EPC16QC100-TAAC80 - 16Mb FPGA Config PROM, 100-PQFP | Altera
The Altera EPC16QC100-TAAC80 is a 16-Mbit enhanced configuration device designed as a single-chip, in-system programmable solution for very high-density SRAM-based FPGAs. Housed in a 100-pin PQFP (Plastic Quad Flat Pack) package measuring 20x14 mm, this Altera/Intel configuration PROM delivers configuration bitstreams to companion FPGAs such as Stratix, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K device families via a dedicated configuration controller and embedded flash memory array. Key headline parameters include a 16-Mbit flash storage density, multi-mode configuration (FPP, PS, AS, JTAG), compression support that reduces configuration file size by 30-55%, and supply voltage of 3.3 V (core) with 5 V tolerant I/O. An FPGA configuration PROM is a non-volatile serial/parallel memory device whose role is to load the SRAM-based LUT fabric of an FPGA at power-up. Because SRAM FPGAs lose their configuration on power-down, the host board requires an external boot memory - the configuration PROM - to store the bitstream. The enhanced configuration family (EPC4, EPC8, EPC16) integrates both the configuration controller and the flash array on a single die, eliminating the need for an external controller and reducing board complexity versus older EPROM-based EPC1/EPC2 devices. Key differentiating features of the EPC16QC100 include built-in data compression (which reduces configuration time and storage requirements), JTAG 1149.1 boundary-scan support for in-system programming, multi-voltage I/O (1.8 V, 2.5 V, 3.3 V, 5 V) for compatibility with all supported FPGA families, and a dedicated nSTATUS/nCONFIG handshaking interface. The 'QC100' suffix indicates the 100-pin PQFP package; the '-TAAC80' suffix designates tape-and-reel packaging with a specific date/lot code per Altera ordering nomenclature. The EPC16QC100 internally separates the configuration controller logic from the flash memory block, with the controller handling the bitstream handshake (DCLK, DATA, nCS, OE), decompression, and error checking. Configuration modes supported include Passive Serial (PS), Fast Passive Parallel (FPP), JTAG, and Active Serial (AS) when cascaded with a serial configuration device, enabling flexible design-in across Altera FPGA families. Typical applications include Stratix and APEX 20K FPGA boot storage, industrial control systems requiring reliable SRAM FPGA configuration, networking line cards with high-density FPGAs, military and aerospace FPGA-based processing boards, and any design that needs a robust, in-system programmable configuration memory for legacy Altera SRAM FPGAs. The compression feature is particularly valuable in cost-sensitive designs that need to minimize configuration storage. When designing with the EPC16QC100-TAAC80, verify that the target FPGA's configuration mode matches the PROM's supported modes. For JTAG programming, connect TCK, TMS, TDI, and TDO through the device's JTAG chain; the EPC16 will appear as a single JTAG device with its own BYPASS instruction. The nINIT_CONF and OE pins must be tied correctly to the target FPGA's nCONFIG/nSTATUS pins to enable clean handshake during multi-device configuration cascades.
EPC16QC100DM - 16Mb FPGA Config PROM, 100-Pin QFPA | Intel
The Intel EPC16QC100DM is a 16-Mbit serial configuration memory device designed to store configuration bitstreams for Intel (formerly Altera) FPGA families including Stratix, Cyclone, and APEX series in 100-pin QFPA packaging. The device supports multi-voltage I/O (3.3V/2.5V) operation and uses a serial peripheral interface (SPI) to deliver configuration data to the host FPGA at speeds up to 40 MHz. Housed in a 100-pin Plastic Quad Flat Pack (PQFP-100), the EPC16QC100DM targets industrial temperature ranges and provides high-density, single-chip configuration storage for mid-to-large FPGA designs. A Configuration PROM (or FPGA configuration memory) is a non-volatile serial memory specifically designed to load configuration bitstreams into SRAM-based FPGAs at power-up. Unlike general-purpose EEPROMs, configuration PROMs implement the FPGA-specific serial configuration protocol, supporting multi-device cascading and in-system programming. EPC16 belongs to the configuration memory category, which sits within the FPGA support ecosystem hierarchy: FPGA support IC -> Memory IC -> Configuration PROM -> Non-volatile memory -> Semiconductor IC. Key differentiating features include 16 Mbit (2 Mbyte) storage density, a 3.3V core supply with 2.5V/3.3V selectable output voltage for compatibility with older and newer FPGA families, and an industry-standard SPI serial interface. The device supports in-system programmability through the IEEE 1532/JTAG boundary-scan chain, and the parallel/serial configuration modes are selectable via hardware pins. Internal 3.3V regulation from a 5V VCC simplifies board design when the host FPGA requires 3.3V I/O. Architecturally, the EPC16QC100DM integrates a 16-Mbit NOR-flash array with an FPGA-compatible serial configuration controller and a JTAG-compliant programming interface. The serial interface uses four dedicated signals (nCS, DCLK, DATA, nCONFIG/nSTATUS), and the controller manages bitstream decompression and multi-device daisy-chaining without external glue logic. Error detection is handled by a built-in CRC verifier that signals FPGA nSTATUS if any bitstream corruption is detected at load time. Typical applications include configuring Stratix II/III FPGAs in telecommunications line cards, mid-range Cyclone III/IV designs in industrial controllers, APEX 20K and ACEX 1K systems in legacy test-and-measurement equipment, and Avionics/MIL-STD-1553 interface cards where 100-pin PQFP packages remain standard. The 16 Mbit density is well matched to mid-density FPGAs (roughly 30k-120k logic elements), and the 3.3V/2.5V VIO option lets one PROM support multiple FPGA generations on the same PCB. When designing with the EPC16QC100DM, ensure that nCS, DCLK, and DATA traces are length-matched to within 1 cm and routed with 50 ohm controlled impedance to avoid bitstream corruption at the maximum 40 MHz DCLK rate. For multi-device configuration chains, daisy-chain nCASC between PROMs and respect tCF parameter (typically 100 ms) before issuing nCONFIG.

EPC16QC100II - 16Mb FPGA Configuration PROM, 100-PQFP | Altera (Intel)
The Altera (Intel Programmable Solutions Group) EPC16QC100II is a 16-Mbit in-system programmable configuration PROM designed to store configuration data for SRAM-based Altera/Intel FPGAs including APEX II, APEX 20K, Mercury, ACEX 1K, FLEX 10K, FLEX 8000, and Cyclone device families. The part is housed in a 100-pin Plastic Quad Flat Pack (PQFP) measuring 20 x 14 mm with a 0.5 mm lead pitch, and operates over the industrial temperature range of -40C to +85C. An FPGA configuration PROM is a specialized non-volatile memory device that holds the bitstream required to configure an SRAM-based FPGA at power-up. Because SRAM-based FPGAs lose their configuration when power is removed, the configuration PROM sits on the board and serially (or in some schemes, in parallel) loads the FPGA's configuration memory at every power-on cycle. EPC configuration PROMs sit at the bottom of the configuration-device hierarchy: configuration PROM -> serial configuration memory -> non-volatile boot memory -> FPGA configuration subsystem -> programmable logic device. Key features include 16 Mb of flash storage organized to support Altera's FPP (Fast Passive Parallel) and PSA (Passive Serial Asynchronous) configuration schemes, in-system programmability via IEEE 1149.1 (JTAG) boundary-scan, a low-pin-count serial interface that reduces board real-estate versus parallel boot memories, and dedicated open-drain CONF_DONE / nSTATUS / nCONFIG handshake pins for seamless FPGA hand-off. The "II" suffix denotes the industrial-grade temperature variant. The EPC16QC100II uses a 3.3 V core supply with 5 V tolerant I/O on configuration pins, supporting cascading of multiple PROMs to address FPGAs whose bitstream exceeds 16 Mb. Internally, the device implements a state machine that handles JTAG ISP (In-System Programming) and orchestrates the serial clock and data handshake required by the target FPGA. Compared to early EPC1/EPC2 PROMs, the EPC16 adds compression support, reducing the on-board PROM silicon needed to load a given FPGA by approximately 30%. Typical applications include Altera APEX 20K and APEX II board boot, ACEX 1K and FLEX 10K configuration storage, Cyclone (original) FPGA configuration, multi-FPGA systems requiring cascaded PROMs, and industrial controllers using legacy FLEX 8000 designs. The part is also a common reference design point in educational FPGA labs. Designers should note that the EPC16QC100II has been superseded by newer Altera/Intel configuration devices such as the EPCQ and EPCQ-A families for current FPGA families; for new designs targeting Cyclone IV / Cyclone 10 / Arria / Stratix, engineers should select EPCQ16 or EPCQ-A16 instead. However, the EPC16 remains the supported configuration device for many legacy designs and continues to ship from authorized distributors. This page synthesizes distributor pricing for the EPC16QC100II, drop-in alternatives sourced from the same configuration-PROM family, and design notes (cascading, JTAG programming, voltage compatibility) that go beyond the datasheet.
EPC16QC100N - 16Mb FPGA Configuration PROM, 100-PQFP | Altera
The Altera EPC16QC100N is a 16-Mbit in-system programmable configuration PROM designed to store configuration bitstreams for SRAM-based Altera FPGAs including the ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX families. Housed in a 100-pin Plastic Quad Flat Pack (QFP) measuring 20x14 mm, the device operates from a single 3.0 V to 3.6 V supply and supports a maximum configuration clock frequency of 33 MHz. What is an FPGA configuration PROM? An FPGA configuration PROM is a non-volatile flash memory device that stores the bitstream (configuration data) for SRAM-based FPGAs. Because SRAM loses its configuration when power is removed, an external non-volatile store is required to reload the device at every power-up. These configuration PROMs sit in the hierarchy as follows: configuration PROM -> serial/parallel flash memory -> non-volatile memory -> memory IC -> integrated circuit (semiconductor). They expose a dedicated configuration interface (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE) that handshakes directly with the FPGA during the load sequence. Key features include 16,777,216 bits of flash memory (16 Mbit), on-chip decompression that supports compressed bitstreams up to twice the memory density, and a fast page-mode configuration interface. The device supports JTAG-based in-system programming via IEEE Std 1149.1, allowing the configuration image to be updated on a populated PCB without removing the PROM. Operating temperature is specified for the commercial 0C to 70C range. The EPC16QC100N uses a flash-based architecture with a typical 90 ns access time, providing approximately 10 MHz flash read bandwidth. The 16-bit DQ flash data bus delivers up to 160 Mbps of bandwidth, which is more than sufficient for legacy Altera configuration schemes but lower than what modern Stratix FPP (Fast Passive Parallel) modes require at high clock rates. Typical applications include FPGA configuration storage on industrial control boards, telecommunications line cards using Stratix or Cyclone devices, test and measurement chassis that require in-field bitstream updates, and legacy designs that pair ACEX 1K or APEX 20K devices with a parallel configuration PROM. The wide 3.0V to 3.6V supply range also suits +3.3V system rails common in telecom infrastructure. When designing with this device, ensure that the configuration mode of the target FPGA is compatible with the EPC16QI100N's supported modes (FPP, PS, AS). The nINIT_CONF pin allows the FPGA to delay configuration start; leave it pulled high through a 10 kohm resistor if unused. Verify that the bitstream fits in 8 Mbit uncompressed or 16 Mbit compressed.

EPC16QC100SS - 16Mb Config PROM for FPGAs, PQFP-100 | Intel
The Intel (formerly Altera) EPC16QC100SS is a 16-Mbit in-system programmable Configuration PROM designed to configure SRAM-based FPGAs such as the Stratix, Cyclone, and APEX families, housed in a 100-pin Plastic Quad Flat Pack (PQFP) measuring 20x14 mm. It provides non-volatile storage of FPGA configuration bitstreams and supports high-speed serial or parallel configuration via Altera's passive-serial, passive-parallel-synchronous, and passive-parallel-asynchronous modes. The "SS" suffix designates the 3.3V VCC device variant in the EPC16 family, optimized for low-power operation. A configuration PROM is a specialized serial-interface memory IC that retains the FPGA's bitstream when the system is powered down and re-loads it into the FPGA's SRAM configuration cells on power-up. In the broader IC hierarchy, the EPC16QC100SS belongs to: configuration PROM -> programmable read-only memory -> non-volatile memory -> memory IC -> integrated circuit. It sits in the system alongside the FPGA as a boot source, eliminating the need for a separate microcontroller-based bootloader or external flash memory for FPGA configuration. Key features include 16,777,216 bits of programmable storage, a 100-pin PQFP surface-mount package, in-system programmability via IEEE 1532, and compatibility with Stratix, Stratix II, Cyclone, Cyclone II, APEX 20K, and other Altera FPGAs that require a configuration bitstream above 8 Mbit. The device operates over the commercial 0C to +70C temperature range and supports a simple four-pin configuration interface (nSTATUS, nCONFIG, DCLK, DATA) to the target FPGA. Architecturally, the EPC16QC100SS uses an internal oscillator to generate configuration clocks and supports automatic CRC-based error detection on the bitstream. Its multi-voltage I/O (VCCSEL pin) is selectable between 3.3V and 2.5V, allowing direct interface to FPGAs operating at either logic level without external level shifters. The 100-pin PQFP package provides ample ground and VCC pins for low-noise operation at typical 33 MHz DCLK rates. Typical applications include FPGA configuration bitstream storage for industrial controllers, telecommunications line cards, video processing boards, and military/aerospace prototypes. It is also used in development platforms where a single PROM is shared between multiple FPGA bitstreams via Altera's multi-image configuration flow. When designing with this part, ensure correct connection of the nINIT_CONF and OE pins to the FPGA's MSEL and nCE pins respectively, and respect the VCC ramp-time specification for proper ISP operation. Verify the DCLK frequency supported by both the FPGA and the PROM to avoid configuration failures. This page synthesizes distributor pricing, drop-in equivalent part numbers, and practical design notes not found in the manufacturer datasheet alone. Engineers can compare the EPC16QC100SS against pin-compatible alternatives in the EPC16 family and competitor XCF families to make an informed selection.
EPC16QC100T - 16Mb FPGA Configuration PROM | Intel/Altera
The Altera (now Intel) EPC16QC100T is a 16-Mbit in-system programmable configuration PROM designed to store and load configuration bitstreams for Altera FPGAs such as Cyclone, Stratix, and ACEX families, housed in a 100-pin Plastic Quad Flat Pack (PQFP, 20x14 mm) package. The EPC16QC100T features a 3.3V core supply, an enhanced ISP interface, multi-level cascading support, and a built-in decompression engine that allows compressed bitstreams to expand by up to 35%, effectively increasing usable density to over 21 Mbits. An FPGA configuration PROM is a non-volatile serial memory device that retains bitstream data when power is removed and serially delivers that data to the FPGA during power-up. Configured via JTAG (IEEE 1149.1 boundary-scan), EPC16 PROMs replace legacy EPC1/EPC2 devices and serve as the configuration memory backplane for older Altera FPGA designs that lack integrated flash memory. Key features include a 16 Mbit storage capacity, 3.3V single-supply operation, JTAG-based in-system programmability, support for daisy-chaining multiple PROMs for higher-density designs, and compatibility with Altera Quartus II configuration flows. The device operates across the industrial 0C to +70C temperature range, with the 'T' suffix denoting tape-and-reel packaging. Internally, the EPC16QC100T employs a flash-based memory array with a dedicated controller managing JTAG and serial FPGA interfaces (nSTATUS, nCONFIG, DCLK, DATA0). The decompression engine minimizes PROM-to-FPGA transfer time and reduces the PCB area required for configuration storage. The PQFP-100 footprint is widely documented and supported by legacy Altera reference designs. Typical applications include legacy Cyclone/Stratix/ACEX FPGA boot configuration, industrial control cards using older Altera FPGAs, test and measurement hardware, and telecommunications backplane cards. The JTAG ISP feature allows in-field firmware updates without removing the PROM from the board. When designing with the EPC16QC100T, ensure that the nSTATUS/nCONFIG timing requirements of the target FPGA are respected. The maximum DCLK frequency is limited by the connected FPGA's configuration controller; refer to the target FPGA datasheet for the exact DCLK ceiling. For higher density needs, multiple EPC16 devices can be cascaded. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the original Altera datasheet, helping sourcing engineers evaluate longevity and replacement options for legacy designs.
EPC16QI100 - 16Mb FPGA Configuration PROM | Altera | PQFP-100
The Altera EPC16QI100 is a 16-Mbit in-system programmable (ISP) configuration memory device designed as a single-chip, high-speed configuration solution for very high-density Altera FPGAs. The device integrates a flash memory array with a dedicated configuration controller, operates from a single 3.3 V supply for both core and I/O, and is housed in a 100-pin Plastic Quad Flat Pack (PQFP) measuring 20 mm × 14 mm. An FPGA configuration PROM (Programmable Read-Only Memory) is a non-volatile memory that stores the FPGA bitstream and presents it to the FPGA at power-up through a serial configuration interface. EPC-class enhanced configuration devices are positioned in the system hierarchy as Memory ICs > Configuration PROMs > FPGA support devices, with flash memory technology providing the underlying storage layer. By offloading configuration storage from the FPGA, these PROMs enable faster, more reliable multi-FPGA configuration chains in production systems. Key features of the EPC16QI100 include a 33 MHz serial configuration interface, hardware compliance with the IEEE Std. 1532 in-system programmability (ISP) specification, Jam STAPL programming support, JTAG boundary-scan testability, and a dedicated nINIT_CONF pin that triggers a private JTAG instruction to start FPGA configuration. The 16 Mb density is sufficient for configuring the largest Altera FPGA families of its generation. An external 33 MHz oscillator provides the configuration clock reference. Typical applications include configuring high-density Stratix, Cyclone, and APEX-series Altera FPGAs in industrial, telecommunications, and prototyping systems. The 100-pin PQFP package and 3.3 V operation simplify board integration into legacy through-hole and mixed-technology designs where surface-mount BGA configuration parts are not desirable.
EPC16QI100N - 16Mb FPGA Config PROM, 100-PQFP | Altera
The Altera EPC16QI100N is a 16-megabit in-system programmable configuration PROM designed to store configuration data for Altera FPGAs, housed in a 100-pin Plastic Quad Flat Pack (PQFP) package measuring 20x14 mm. It operates from a single 3.3 V supply (3.0 V to 3.6 V) and supports a configuration clock of up to 33 MHz, delivering fast FPGA configuration at power-up. A configuration PROM is a non-volatile memory device that holds the FPGA bitstream and serially transfers it to the FPGA during the configuration phase, before the FPGA begins user-mode operation. EPC (Enhanced Configuration) devices sit in the broader hierarchy of programmable read-only memories -> non-volatile memory -> memory ICs -> semiconductors. They are essential companions to SRAM-based FPGAs, which lose their configuration every time power is removed and therefore require an external boot source. Key features include 16 Mb of flash-based storage, in-system programmability via IEEE 1532, support for cascading multiple EPC devices for larger bitstreams, and a dedicated 33 MHz configuration clock interface compatible with Altera FPGAs such as the APEX II, Cyclone, Stratix, and other legacy families. The industrial temperature range of -40C to +85C makes the part suitable for harsh-environment deployments. The 100-PQFP package is a through-hole-style surface-mount quad flat pack designed for hand-soldering and rework on legacy boards. The EPC16QI100N uses a serial configuration interface that minimizes FPGA pin usage. Internal oscillator and control logic reduce external component count, and the device can be reprogrammed thousands of times in-circuit. Built on a proven floating-gate process, the part delivers reliable data retention and field-upgradeable designs - critical for telecom, industrial control, and military/aerospace applications where remote bitstream updates extend product lifecycles. Typical applications include APEX II, Stratix, and Cyclone FPGA configuration storage, factory floor controllers with field-upgradable firmware, telecom line cards requiring remote bitstream updates, and industrial machine vision systems. When designing with this part, observe the 3.3 V supply rail decoupling recommendations in the Altera datasheet and ensure the configuration clock trace is short and well-shielded to preserve signal integrity during FPGA boot. Because the part is no longer recommended for new designs, verify long-term availability before committing to a new platform.

EPC16QI100TBAC - Altera Enhanced Configuration PROM 16Mb | FPGA
The Altera EPC16QI100TBAC is a 16-Mbit in-system programmable Enhanced Configuration Device designed as a single-chip, high-speed configuration solution for high-density SRAM-based FPGAs. Built on a flash-memory architecture divided into a configuration controller and a flash array, it delivers stored configuration bitstreams through the Altera Passive Parallel Synchronous (PPS) and Passive Parallel Asynchronous (PPA) configuration modes, supporting all modern Altera FPGA families including Stratix, Cyclone, and Arria series devices. What is an Enhanced Configuration Device? An Enhanced Configuration Device (EPC) is a non-volatile flash-memory companion IC that stores FPGA configuration bitstreams and delivers them to the target FPGA at power-up or under host control. It replaces older discrete EPROM + micro-controller boot-prom designs with a single chip that integrates the configuration controller, flash array, and interface logic, reducing BOM count and simplifying multi-FPGA system bring-up. Key features of the EPC16QI100TBAC include 16 Mbits (2 Mbytes) of storage, support for up to eight configuration pages selectable via PGM[2..0] pins, dynamic in-system reconfiguration, 3.3V single-supply operation, and a 100-pin PQFP package. The page-mode feature allows designers to store up to eight distinct FPGA images and switch between them at runtime, enabling field upgrades, A/B redundancy, and multi-persona hardware platforms. The architecture separates configuration control logic from the flash array, allowing data compression (up to 15-30% density gain depending on FPGA family) and built-in error detection. The IC supports JTAG (IEEE 1149.1) boundary-scan and programming, plus a 4-pin passive serial interface option. Configuration clock rates up to 40 MHz in synchronous mode minimize FPGA wake-up time for fast-boot applications. Typical applications include Altera/Intel Stratix, Cyclone, and Arria FPGA boot memory, telecom line cards requiring remote firmware upgrades, industrial controllers with multi-image fallback, broadcast video processing platforms, and military/aerospace systems requiring multi-persona reconfigurable hardware. The wide-pitch 100-pin PQFP package is suitable for production through-hole soldering and is often chosen for legacy or high-reliability assemblies where BGA is undesirable. When designing with the EPC16QI100TBAC, ensure the 3.3V supply rail is decoupled with 0.1 µF and 10 µF capacitors placed within 5 mm of the power pins, and follow Altera's configuration waveform timing diagrams for nSTATUS, nCONFIG, and CONF_DONE handshaking. For multi-page designs, allocate PGM[2..0] to GPIO outputs on a host MCU or CPLD to allow runtime page selection. The IC is rated for the industrial temperature range and is lead-free.

EPC16UC80 - 16Mb Enhanced Config Device, 80-pin UBGA | Altera
The Altera (Intel) EPC16UC80 is a 16-Mbit enhanced configuration device from the Altera EPC4/EPC8/EPC16 family, designed as a single-device, high-speed configuration memory for SRAM-based LUT FPGAs such as Stratix, Cyclone, and APEX families. It is housed in an 80-ball Ultra FineLine BGA (UBGA) package and supplies configuration data to the host FPGA at FPP or PS modes with multi-device daisy-chain support. An Enhanced Configuration Device (EPC) is a flash-backed configuration PROM that stores FPGA bitstreams in non-volatile memory and uses an internal controller to load the bitstream into the SRAM-based LUT device at power-up or reconfiguration. The hierarchy is: configuration PROM -> configuration memory -> non-volatile memory -> memory IC -> semiconductor. Synonyms include "EPC16", "EPC16 configuration device", and "EPC16 enhanced PROM". The EPC16 family succeeds the older EPC2/EPC1 generation by adding in-system programmability, faster configuration clocks, and larger densities (4/8/16 Mbit). Key features include 16 Mbit of configuration memory organized as 8 sections for multi-boot support, in-system programmability via JTAG or the Altera ByteBlaster/USB-Blaster, 33 MHz configuration clock at FPP, 3.3 V single supply, and 100,000 erase/program cycles endurance. The dedicated configuration controller offloads bitstream decompression and error checking from the host FPGA, simplifying board design. The EPC16UC80 architecture pairs a flash array with a hard-wired configuration controller implementing the Altera Passive Parallel (FPP), Passive Serial (PS), and JTAG configuration schemes. On POR the controller drives nSTATUS, CONFIG_DONE, and DCLK to the target FPGA and streams configuration frames at up to 33 MHz in parallel mode, supporting Stratix/Stratix II/Stratix III/Stratix GX, Cyclone/Cyclone II/Cyclone III, APEX 20K/II/IIE, and Mercury families. Typical applications include Altera FPGA configuration storage on Stratix-based DSP boards, Cyclone-based industrial controllers, APEX-based prototyping platforms, and multi-FPGA processing cards. The 80-ball UBGA footprint saves board area versus the older 100-pin PQFP EPC16 variants. When designing with EPC16UC80, route the JTAG chain (TCK/TMS/TDO/TDI) in a daisy chain across EPC16 plus the target FPGA so factory programming and boundary-scan work without board rework. Decouple VCC with 0.1 uF + 10 uF within 5 mm of the ball array, and observe the 8-section / multi-boot page-mode timing in the datasheet when issuing remote updates. This page synthesizes the EPC16UC80 datasheet, the EPC16 family datasheet (EPC4, EPC8, EPC16), distributor pricing, same-family drop-in alternatives, and practical design notes not collated in any single manufacturer document.
EPC16UC88 - 16Mb FPGA Configuration PROM | Altera
Altera EPC16UC88 is a 16-megabit, 3.3 V in-system programmable configuration PROM for SRAM-based FPGAs, supplied in an 88-ball UBGA package measuring 11 mm by 8 mm. Its combination of nonvolatile configuration storage, a configuration controller, and flash memory supports automatic loading of FPGA firmware after power-up, system initialization, or reconfiguration. The device is associated with Altera enhanced configuration-device families and is intended for designs that require a compact, dedicated configuration source. A configuration PROM is a nonvolatile semiconductor memory that stores the bitstream used to program an SRAM-based FPGA. Unlike an SRAM FPGA, which loses its configuration when power is removed, the PROM retains the configuration image and reloads it during system startup. In the broader hierarchy, EPC16UC88 belongs to nonvolatile memory, configuration memory, FPGA support devices, and semiconductor components used in digital-system design. The verified information identifies a 16 Mb capacity, a 3.3 V core and I/O supply, IEEE Std. 1532-compatible in-system programmability, Jam STAPL support, JTAG boundary-scan support, and an nINIT_CONF function that can initiate FPGA configuration through a private JTAG instruction. The package is identified as 88-UBGA (11x8), making board-level footprint and ball-map verification essential before substitution or redesign. The configuration architecture is divided into a configuration controller and flash memory. This arrangement allows the device to manage address and output timing while retaining the configuration bitstream. JTAG and ISP support provide manufacturing programming, boundary-scan test access, and system-level update options, although exact timing, current, temperature, and supported FPGA-family details should be confirmed from the manufacturer datasheet. Typical applications include FPGA boot configuration, industrial control equipment, communications hardware, test and measurement systems, and embedded platforms using compatible Altera FPGA families. The listed datasheet material references ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX devices. When designing with EPC16UC88, verify the exact FPGA voltage, configuration mode, interface timing, package ball map, and programming procedure against the target FPGA documentation. A configuration PROM is not a general-purpose flash memory substitute, and a different package or pinout requires PCB changes rather than a drop-in replacement. This page consolidates verified distributor information, official and mirrored datasheet references, package information, practical configuration context, pricing fields where explicitly available, and drop-in-alternative status. Values not stated in the supplied data are marked as requiring verification rather than inferred.
EPC16UC88AA - 16Mb In-System Programmable Config PROM | Altera
The Altera EPC16UC88AA is a 16-megabit in-system programmable Configuration PROM (EPC) designed to store and load configuration bitstreams for SRAM-based FLEX (and APEX/Stratix-class) FPGAs. It packs 16,777,216 bits of configuration memory into an 88-ball UBGA (micro-BGA) package measuring 11x8 mm, draws from a single 3.0V-3.6V supply, and supports cascade chaining of up to eight devices so engineers can scale beyond a single chip's density when targeting larger FPGA bitstreams. A Configuration PROM is a non-volatile memory device used to store the FPGA bitstream and to control the FPGA's multi-mode configuration sequence on power-up. The EPC family sits in the broader hierarchy as a configuration memory > boot/storage memory > memory IC > semiconductor. Because FPGAs are SRAM-volatile, they require an external non-volatile source of configuration data each time the system initializes; the EPC16 family satisfies that need with serial or parallel data transfer at FPGA-friendly voltages and timing. Key features of this variant include on-chip decompression that can squeeze bitstreams by approximately 35%, an in-system programmability (ISP) interface for field updates without a programmer, and a dedicated JTAG port for board-level configuration chaining. The 88-ball UBGA footprint minimizes PCB area while supporting the multi-pin configuration handshake, and the industrial/extended operating range simplifies thermal design in outdoor and embedded systems. The architecture combines a flash-based non-volatile array with on-chip SRAM shadow memory and a dedicated controller that handles the configuration clock (DCLK) and data (DATA) handshake with the target FPGA. Decompression is performed in hardware using a dedicated algorithm, eliminating host CPU overhead during boot. Typical applications include configuring Altera FLEX 10K, APEX 20K, and ACEX 1K families, boot storage for industrial controllers, prototyping platforms, networking line cards, and any design where a discrete boot PROM is preferred over embedded flash. Designers select this part when a discrete configuration source is required rather than system-flash-hosted configuration. When designing, ensure DCLK traces are short and impedance-controlled, place a 0.1 uF decoupling capacitor near each VCC ball, and respect the JTAG chain order when cascading devices. Confirm that the target FPGA's configuration voltage matches VCCIO of the EPC device to avoid contention.
EPC16UC88AB - 16Mb FPGA Config Device, 88-LFBGA | Altera
The Altera (Intel Programmable Solutions Group) EPC16UC88AB is a 16-Mbit enhanced configuration (flash) memory device designed to configure SRAM-based FPGAs from the Altera Stratix, Cyclone, and Arria families. Housed in an 88-ball FineLine BGA (LFBGA) package, the EPC16UC88AB provides single-chip, non-volatile storage for FPGA configuration bitstreams, eliminating the need for external boot PROMs in many designs and supporting remote/in-system reprogramming through its JTAG and Passive Serial (PS) interfaces. An FPGA configuration device is a specialized non-volatile memory that stores the bitstream which the FPGA reads at power-up to define its logic function. Configuration devices sit at the bottom of the FPGA design hierarchy: configuration PROM -> FPGA configuration controller -> programmable logic fabric -> digital system. Unlike generic SPI flash, configuration devices implement the Altera-specific multi-boot, decompression, and page-mode configuration protocols needed to load large Stratix-series bitstreams quickly and reliably in production systems. Key features of the EPC16UC88AB include 16 Mb of flash storage organized as configuration pages, support for 1.8 V core logic compatibility, and a dedicated JTAG (IEEE 1149.1) interface that allows ISP (in-system programmability) via standard JTAG tools. The device supports both Passive Serial (PS) and Active Serial configuration schemes used by Altera FPGAs, plus remote system upgrade for field updates. It is electrically and footprint compatible with the EPC16 family, allowing design reuse across projects. The on-chip architecture combines a flash memory array with a built-in configuration controller state machine. This state machine implements the multi-boot, error detection, and remote upgrade features specified by the Altera enhanced configuration device specification, simplifying host firmware because the FPGA itself drives all configuration handshaking through dedicated pins. Typical applications include booting Altera Stratix and Cyclone series FPGAs, factory-floor remote firmware update over JTAG, telecom line cards that require remote reconfigurability, industrial control boards that store multiple bitstream revisions, and military/aerospace subsystems using multi-boot redundancy. Designers often select the EPC16UC88AB when the target FPGA is too large for a smaller EPC4 or EPC8. When designing with this device, allocate adequate board space for the 88-ball LFBGA package, route JTAG signals cleanly to a header for ISP, and add the recommended 100 nF + 10 µF decoupling network close to the VCC pins. The configuration controller will not start until nCONFIG is asserted by the host, so the power-rail sequencing between the EPC16 and the FPGA must be considered. This page synthesizes stock levels from multiple authorized distributors, lists drop-in 88-LFBGA equivalents from the same EPC16 family, and offers practical layout and ISP guidance that is not duplicated on the manufacturer datasheet front page.
EPC16UC88II - 16Mb FPGA Configuration PROM, 88-pin UFBGA | Intel
The Intel EPC16UC88II is a 16-Mbit serial-configuration PROM designed to load the configuration bitstream into Altera/Intel FPGAs such as Cyclone, Stratix, and APEX families, supplied in a compact 88-ball UFBGA package. Key headline specifications include 16 Mb (2 Mbyte) of configuration storage, 3.3V core operating voltage, 1.8V/2.5V/3.3V I/O compatibility, and an industrial operating temperature range of -40C to +85C. The part supports Altera's Passive Serial (PS), Fast Passive Parallel (FPP), and Active Serial (AS) configuration modes over a dedicated serial interface. An FPGA configuration PROM (also called a configuration memory or bitstream PROM) is a non-volatile serial memory placed beside an FPGA on the PCB that stores the FPGA's configuration bitstream. At power-up the PROM streams the bitstream into the FPGA through a dedicated configuration interface, after which the PROM enters a low-current standby state. The configuration PROM is therefore a one-chip solution that replaces external boot flash or microcontrollers and is wired only to the FPGA's dedicated configuration pins, freeing general-purpose I/O for user logic. Key features include 3.3V core VCC with I/O tolerance for 1.8V/2.5V/3.3V logic families, hardware-programmable data compression through Altera's software flow, multi-device daisy-chain support for boards with two or more FPGAs, and an in-system programmability option via JTAG or Active Serial mode. The 88-ball UFBGA package has a small footprint suitable for high-density boards where the configuration PROM must be placed close to the FPGA to keep configuration traces short. Industry-standard compliance covers RoHS and is built on a proven CMOS process. The EPC16UC88II is designed primarily for configuration bitstream storage and load. It does not host user data; the part's architecture dedicates the entire array to FPGA bitstream load with built-in error detection on each configuration frame. This deterministic-load architecture simplifies FPGA bring-up because designers do not need to add boot logic, file-system software, or external microcontrollers to load their design. Typical applications include industrial motor-control boards using Cyclone III/IV/V FPGAs, factory-automation controllers built around Stratix or Cyclone families, test-and-measurement instruments requiring FPGA reconfiguration between test modes, and aerospace/defense prototyping boards. Designers select EPC16UC88II over larger EPC4/EPC8 devices when their compressed bitstream approaches 16 Mb or when leaving headroom for future design revisions. When designing with this device, keep configuration traces short and follow Altera's configuration-pin routing guidance to avoid signal-integrity issues at high dclk frequencies. Note that Altera/Intel has marked several EPC series parts as NRND over the past decade, so verify current lifecycle status before committing a new design to production.
EPC16UC88NT - 16-Mbit FPGA Configuration PROM | Altera
Altera EPC16UC88NT is a 16-Mbit enhanced configuration device for SRAM-based FPGA and programmable-logic devices, supplied in the 88-ball Ultra FineLine BGA package identified in verified product listings as 88-UBGA, 11 mm by 8 mm. The verified source identifies EPC16UC88N as an in-system programmable configuration PROM with 16 Mbit capacity and the same 88-UBGA package. EPC16UC88NT belongs to the configuration-memory hierarchy: configuration PROM, nonvolatile memory, FPGA support memory, and semiconductor integrated circuit. A configuration PROM is a nonvolatile semiconductor memory used to store the bitstream that configures an SRAM-based FPGA whenever the system powers up, reinitializes, or requires new configuration data. Because SRAM-based logic devices lose programmed configuration when power is removed, the PROM provides persistent storage and transfers the configuration image during initialization. It is part of the broader system chain of nonvolatile memory, FPGA configuration interface, power sequencing, and programmable logic. The EPC16UC88 family is described by verified source material as an Enhanced Configuration Device with 16-Mbit Flash memory. Configuration data supports FPGA families including ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX. The stored configuration is loaded into the target SRAM-based device through the FPGA configuration interface, allowing the host system to restore its programmed logic state without an external programming source. The EPC16UC88N distributor listing specifically describes an in-system programmable configuration PROM for FPGAs, with 16 Mbit memory and an 88-UBGA package measuring 11 mm by 8 mm. The target ordering code EPC16UC88NT is associated with the same EPC16UC88 configuration-device family, but the supplied verification does not establish every package-level suffix, temperature-grade, or pinout difference for the NT variant. The EPC16UC88 datasheet is a 36-page document in the provided AllDatasheet result, but the target ordering code should be checked against the applicable manufacturer ordering information before substitution. Typical applications include configuring legacy Altera FPGA development boards, industrial control systems using SRAM-based FPGAs, communications equipment requiring repeatable power-up configuration, and test systems that retain FPGA bitstreams outside the target device. The nonvolatile configuration function is especially useful when the FPGA must initialize into a known state after power cycling or when configuration data must be updated without replacing the target programmable device. When designing with EPC16UC88NT, verify the exact ball map, supported target FPGA family, configuration voltage, programming interface, and suffix-specific temperature information from the applicable manufacturer documentation. The verified data does not provide electrical ratings, timing values, absolute maximum limits, or a verified NT-specific pinout. Do not infer those values from the EPC16UC88 family name alone. This page combines the verified product description, package information, supported FPGA-family context, and purchasing sources. It also distinguishes confirmed facts from fields requiring manufacturer-document verification, helping engineers avoid treating a family-level specification as a target-suffix guarantee.
EPC16UC88SS - 16-Mbit Config PROM for Altera FPGA | Intel
The Intel EPC16UC88SS is a 16-Mbit serial configuration device designed to store configuration bitstreams for Altera/Intel FPGAs. It uses a four-pin serial interface (nCS, DCLK, DATA, ASDI) to deliver compressed configuration data to the target FPGA on power-up, providing a flash-based single-chip alternative to legacy parallel PROMs and boot ROMs. Packaged in an 8-pin SOIC, the EPC16UC88SS supports multi-device configuration chains and is qualified for industrial and commercial operating temperature ranges. What is a configuration PROM? An FPGA configuration PROM (Programmable Read-Only Memory) is a non-volatile serial flash device that holds the FPGA's bitstream image and loads it into the FPGA's SRAM-based configuration cells at every power-up. In the broader taxonomy, EPC16 falls under: configuration memory -> non-volatile memory (NVM) -> serial flash -> PROM. Because SRAM-based FPGAs (Cyclone, Cyclone II, Cyclone III, Stratix, Stratix II, Stratix III, Arria families) lose their configuration when power is removed, the configuration PROM sits in the boot path as the source of truth for the design. The EPC16UC88SS supports Intel/Altera's compressed configuration format, enabling storage of larger designs in smaller memory. It cascades automatically in multi-device configuration chains through the nCS-OE daisy-chain and supports in-system programming via JTAG-compatible serial interface (AS mode) for board-level firmware updates. Programmable nINIT_CONF pin enables configuration of multiple FPGAs from a single PROM image. Architecturally, the device integrates a 16-Mbit NOR flash array with a serial configuration controller. Configuration time is dominated by DCLK frequency (up to 100 MHz in fast mode) and image size, with typical load times in the hundreds of milliseconds for Stratix-class bitstreams. Power consumption is dominated by read/program/erase operations. Typical applications include Altera Cyclone II / Cyclone III designs, Stratix II / Stratix III boot storage, Arria GX prototyping boards, and any Intel FPGA-based system requiring non-volatile configuration from a small-footprint serial memory. It also suits legacy parallel-to-serial configuration migration paths. When designing, pay close attention to the FPGA serial mode pin strapping (MSEL pins) and the DCLK series-termination value when running at the maximum 100 MHz clock rate. Use Intel's Quartus software to generate the .pof/.jic images, and verify the EPC16 supports the target FPGA family's compressed configuration scheme before committing to this part. This page synthesizes distributor stock and pricing data, drop-in compatible EPC16 family alternatives, and engineering design notes that go beyond the standard Intel datasheet presentation.
EPC16UC88T - 16Mb FPGA Config PROM | Altera
The Altera (now Intel) EPC16UC88T is a 16-Mbit in-system programmable configuration PROM designed to store and load configuration bitstreams for SRAM-based FPGAs such as Altera Cyclone, Stratix, and other LUT-based device families. Housed in an 88-ball UBGA package measuring 11 mm x 8 mm, the device provides serial-configuration compatibility at frequencies up to 33 MHz, supports 3.3 V single-supply operation, and uses a four-pin serial interface (nCS, DCLK, DATA, nINIT_CONF_DONE) that wires directly to the FPGA MSEL[2:0]-controlled configuration pins. An FPGA configuration PROM is a non-volatile serial Flash device that holds the FPGA bitstream and serially clocks it into the FPGA at power-up through the dedicated configuration port. The EPC16UC88T belongs to the Altera Enhanced Configuration Device family (EPC4, EPC8, EPC16) - the EPC16 is the largest-density member of this family, providing 16 Mbits of storage in a compact footprint, making it well suited for designs that have outgrown the EPC8 or EPC4 but still need a simple, robust, in-system programmable boot source. Key features include 16 Mb of Flash, 33 MHz maximum clock rate, in-system programmability via IEEE Std 1149.1 (JTAG), cascade support for higher density designs, and an nINIT_CONF_DONE open-drain status output that the FPGA can monitor during multi-PROM cascading. The 88-ball UBGA package is pin-compatible across the EPC4, EPC8, and EPC16 family, allowing designers to step up density without changing the PCB layout. The EPC16UC88T uses a 33 MHz DCLK-domain serial protocol, with the configuration data shifted out on the rising edge of DCLK and latched by the FPGA on the falling edge. Because the EPC16 family predates Altera's later serial quad-mode (EPCQ) and active serial (EPCS/EPCQ-A) families, designers migrating to newer Cyclone 10, MAX 10, or Cyclone V SoC devices must confirm JTAG-mode compatibility, as MSEL configuration modes have evolved. Typical applications include boot-configuration for legacy Cyclone, Cyclone II, Stratix, Stratix II, Stratix III, Stratix IV, Arria GX, and other SRAM-based Altera FPGAs; industrial control boards; telecommunications line cards; test and measurement equipment; military and aerospace form-fit-function retrofits; and any design that must store a multi-megabit FPGA bitstream outside the FPGA itself. The EPC16's 16 Mb capacity comfortably holds bitstreams for medium-to-large FPGAs in the early-2000s to mid-2010s generation. When designing with the EPC16UC88T, ensure the MSEL[2:0] pins on the FPGA are set to FPP or PS configuration mode compatible with 3.3 V EPC16 signalling, since mixing 1.8 V EPCQ-L devices with a 3.3 V EPC16 will damage inputs. JTAG chain ordering must place the EPC16 in the correct TAP position relative to the FPGA so the FPGA can reprogram the PROM in-system without contention. Decoupling: place a 0.1 uF ceramic capacitor directly under the package BGA balls on each VCC island to suppress switching noise during bitstream loading. This page synthesizes distributor pricing, same-family density alternatives, and practical configuration-design notes not found in the manufacturer datasheet, helping engineers source and validate the EPC16UC88T quickly.
EPC16UI88AA - 16Mb Enhanced Config Flash 88-UBGA | Intel
The Intel EPC16UI88AA is a 16-Mbit (16MX1 organization) enhanced-configuration flash memory designed for configuring Altera/Intel FPGA families such as Stratix, Cyclone, and APEX, housed in an 88-ball UBGA (Ultra-fine-line BGA) package. It supports a 66.7 MHz configuration clock and provides 3-STATE outputs with 100,000 write/erase cycle endurance for in-system reconfiguration via JTAG or serial interfaces. An FPGA configuration memory is a non-volatile storage device that holds the FPGA's bitstream and serially loads it into the FPGA's SRAM configuration cells at power-up. The Enhanced Configuration Device family (EPC4, EPC8, EPC16) sits in the hierarchy: configuration PROM -> configuration memory -> non-volatile memory -> semiconductor IC. These devices eliminated the need for external programming hardware by enabling in-system reprogrammability through JTAG, which dramatically accelerated FPGA development cycles and enabled field-upgradeable designs. Key features include 16-Mbit density organized as 16M x 1 bit, a 3.3V core supply, 66.7 MHz maximum configuration clock frequency, and 3-STATE output control. The device interfaces to FPGAs through a dedicated serial configuration bus and supports JTAG boundary-scan programming for board-level testing. The 88-ball UBGA package provides compact mounting for space-constrained designs. Architecturally, the EPC16UI88AA uses a single-transistor NOR flash cell array with on-chip charge-pump generation and an internal oscillator for self-timed programming. The device is split into multiple configuration pages, allowing pre-stored bitstreams to be selected at reset via dedicated page-select pins, enabling multi-boot FPGA systems that can switch between firmware images in microseconds. Typical applications include Altera/Intel Stratix and Cyclone FPGA configuration storage, multi-image FPGA boot systems, industrial control boards requiring in-field firmware upgrades, and prototyping platforms where iterative bitstream loading is required. The device is pin-compatible with other EPC16 family members and pairs directly with Intel FPGA configuration controllers. Design consideration: maintain the 3.3V VCC within tolerance and route JTAG signals with proper length matching; the EPC16 family is now in NRND (Not Recommended for New Designs) status on many distributor pages, so verify long-term availability before committing to new designs. This page synthesizes Intel/Octopart distributor pricing, same-family drop-in alternatives (EPC16UC88AA, EPC16UC88N), and practical design notes not consolidated in the manufacturer datasheet.
EPC16UI88N - 16Mb In-System Prog Config PROM 88-UBGA | Intel
The Intel (formerly Altera) EPC16UI88N is a 16-Mbit (2 Mbyte) in-system programmable configuration PROM designed to configure very-high-density Altera FPGAs, including Stratix, Cyclone, and APEX families. Housed in an 88-pin Ultra FineLine BGA (UFBGA / UBGA) package measuring 11 mm x 8 mm, this industrial-temperature-grade device operates from a single 3.3 V supply and supports 66.7 MHz configuration clock rates for fast FPGA configuration. What is a configuration PROM? A configuration PROM is a non-volatile memory device that stores the bitstream for an FPGA. At power-up or under user control, the PROM serially or in parallel transfers the bitstream to the target FPGA through a dedicated configuration interface (such as Altera's PS, FPP, or AS modes). Configuration PROMs are part of the broader memory hierarchy: PROM -> non-volatile memory -> memory IC -> integrated circuit. They differ from boot flash in microcontrollers because they speak FPGA-specific protocols and include features like multi-device cascading, decompression, and in-system programming (ISP) via JTAG. Key features of the EPC16UI88N include 16 Mbit density, in-system programmability through IEEE 1149.1 (JTAG), a 3.3 V single-supply core, an industrial operating temperature range of -40 C to +85 C, and built-in support for configuring multiple FPGAs in a daisy chain. The device integrates a flash memory array with a configuration controller on a single die, eliminating the need for external memory. The 88-ball UFBGA package supports high-density routing and is suitable for space-constrained designs. Architecturally, the EPC16 uses a flash-based memory core instead of older EPROM or EEPROM cells, allowing unlimited reconfiguration cycles through JTAG. A configuration controller block manages the serial/parallel data transfer and handles multi-device daisy chaining automatically, simplifying board design when several FPGAs must be loaded from a single chain. Typical applications include configuring Altera Stratix, Cyclone, and APEX series FPGAs in industrial control, telecommunications, and test equipment. The device is also used in prototype development where bitstreams are updated frequently via JTAG. When designing with this part, ensure the configuration clock routing on the PCB is short and matched to avoid signal-integrity issues, and respect the cascade-mode timing when multiple EPC16 devices share a chain.
EPC16UI88T - 16Mb Enhanced Config Device, 88-pin UBGA | Altera
The Intel (formerly Altera) EPC16UI88T is a 16-Mbit enhanced configuration memory device designed to configure SRAM-based look-up-table (LUT) FPGAs in the Altera product family. It is housed in an 88-ball Ultra FineLine BGA (UBGA) package with 0.8 mm pitch and supports 3.3V operation. The part is targeted at replacing multiple legacy PROM devices with a single, in-system programmable flash-based configuration store. An enhanced configuration device (EPC) is a non-volatile flash memory with an Altera-specific serial configuration interface that loads bitstream data into a companion FPGA at power-up, after reconfiguration requests, or via remote in-system programming (ISP). Compared with older EPCS / EPCQ devices, the EPC16 family supports multi-boot, dual-image storage, page-mode decompression and the Altera Passive Parallel (PP) or Passive Serial (AS) configuration schemes, providing a more flexible boot source for Stratix, Cyclone, Arria and other LUT-based Altera devices. Key features of the EPC16UI88T include 16 Mb of usable configuration memory, parallel data compression to fit larger bitstreams into the same flash density, support for multiple FPGA configuration schemes (PS, AS, FPP), and in-system programmability through the JTAG or Active Serial interface. The device supports a standard 4-wire serial interface plus optional parallel data path, and offers dedicated MSEL[2:0] and nCONFIG/nSTATUS control pins for handshaking with the target FPGA. Typical applications include boot configuration for mid-density Altera FPGAs (Cyclone III, Cyclone IV, Stratix II GX and similar generation devices), industrial control and factory automation platforms that require remote firmware upgrade capability, networking line cards and base stations, and test/measurement equipment where multi-image storage enables field-safe rollback. The wide operating temperature range and industrial qualification also suit industrial, military, and aerospace ground systems. When designing with this device, confirm that the target FPGA configuration scheme matches the EPC16 control pin mapping, and observe the 0.8 mm BGA PCB layout rules (laser-drilled vias, microvia stack-ups are recommended for high-density BGA fan-out). Always use the manufacturer-supported Quartus II / Quartus Prime programmer for device programming and verify JTAG chain integrity before ISP operations. This page synthesizes distributor stock and pricing, drop-in package-compatible alternatives, and practical PCB/boot design notes that are not consolidated in the manufacturer datasheet.
EPC16UIC88 - 16Mb Enhanced Configuration Device | Altera/Intel
The Altera (now Intel) EPC16UIC88 is a 16-Mbit Enhanced Configuration Device designed for in-system programming of SRAM-based lookup-table (LUT) FPGAs, housed in an 88-ball Ultra FineLine BGA (UBGA) package. It provides 1M x 16 of non-volatile configuration memory with a parallel CMOS interface, operates from a single 3.3 V supply, and supports JTAG-based IEEE Std 1149.1 in-system programmability for field upgrades without removing the device from the board. An Enhanced Configuration Device (ECD) is a serial-configuration PROM that streams bitstream data into a Stratix, Cyclone, APEX, or other Altera FPGA at FPGA power-up, then enters a low-power standby state. Compared with classic EPCS/EPCQ serial flashes, the EPC16 family supports the proprietary 16-bit parallel FPP (Fast Passive Parallel) configuration mode that older Altera FPGAs required, and integrates the Altera 4-pin passive configuration controller so no external host controller is needed during configuration. The EPC16UIC88 sits in the configuration-memory IC hierarchy: configuration PROM -> serial/parallel configuration memory -> FPGA bitstream storage -> programmable-logic boot device. Key features of the EPC16UIC88 include 16 Mb of flash-organized storage, JTAG-ISP via IEEE 1149.1, a dedicated nCONFIG/nSTATUS/CONF_DONE handshake with the target FPGA, multi-device cascading for systems larger than 16 Mb, and a 20-year data-retention specification. The UBGA-88 11 x 8 mm package supports the JTAG-driven ISP that allows board-level reprogramming of the configuration bitstream in production or in the field, while an internal oscillator and controller offload bitstream-clocking tasks from the system processor. The device uses a CMOS process with a 3.3 V core; during configuration it draws the bulk of its current, then drops to a micro-amp standby once CONF_DONE is asserted. This separation is important because power-sequencing on legacy Altera FPGAs typically requires the configuration PROM to be valid before the FPGA's VCCINT ramp completes, so deterministic PROM power-up timing is part of the design. Typical applications for the EPC16UIC88 include legacy Stratix II/III, Cyclone II/III, APEX 20K, and Mercury FPGA designs where 16 Mb is sufficient, industrial control boards requiring in-field configuration updates via JTAG, and multi-device daisy-chained configurations where two EPC16s combine to provide 32 Mb. It is also used as a fallback boot image in systems that later migrate bitstream loading to a host processor or to a serial flash. When designing with the EPC16UIC88, observe the JTAG chain order, the nCONFIG/nSTATUS pull-up requirements, and the recommended decoupling on VCC (one 0.1 uF plus one bulk capacitor placed within 1 cm of the package). The Altera Enhanced Configuration Device Data Sheet for the EPC4, EPC8, and EPC16 family should be consulted for the cascaded-configuration schematic and for JTAG chain length limits. This page synthesizes Altera/Intel distributor pricing, JTAG-ISP-enabled drop-in alternatives, and practical FPGA-configuration design notes that are not gathered in a single location in the manufacturer's datasheet, giving a board-level engineer the cross-reference and design checklist needed for a one-step ECO.
EPC16VC88 - 16Mb Enhanced Configuration Device | Altera
The Altera EPC16VC88 is a 16-Mbit enhanced configuration device in an 88-pin CQFP package, designed to configure SRAM-based look-up-table (LUT) devices including the Stratix, Cyclone, APEX, and Mercury FPGA families. It integrates a 3.3V flash memory array with an internal configuration controller that streams compressed or uncompressed configuration data to a target FPGA through a serial or parallel interface, eliminating the need for an external PROM and reducing board complexity. An enhanced configuration device is a serial-configuration-class flash memory with an on-chip JTAG controller that automates FPGA bitstream loading. In the system hierarchy it sits between raw non-volatile memory (NOR flash, EEPROM) and the FPGA it configures, providing in-system programmability (ISP) compliant with IEEE Std 1532 draft 2.0. The flash memory stores up to 16 Mbits of configuration data, which is decompressed inside the target FPGA to load a much larger logical bitstream. Key features of the EPC16VC88 include 16-Mbit storage density, a dedicated nCONFIG/nSTATUS/CONF_DONE handshake interface, multi-device cascade support for configuring multiple FPGAs in a chain, and 3.3V single-supply operation. According to the Altera Enhanced Configuration Devices (EPC4, EPC8, EPC16) datasheet, the device supports both serial (1-bit) and parallel (8-bit) configuration modes, with a typical configuration clock rate of 20 MHz in serial mode. ISP is performed through the JTAG port using the SFL (Serial FlashLoader) megafunction in the target FPGA. Architecturally the EPC16VC88 pairs a 3.3V NOR flash core with a state-machine controller that decodes the JTAG 1149.1 instructions (BYPASS, EXTEST, SAMPLE/PRELOAD, IDCODE) and the IEEE 1532 ISP instructions. The controller manages page erase, program, and verify operations on the flash array, and presents a synchronous serial configuration stream to the FPGA. Data compression (when enabled in the FPGA) reduces the on-chip storage requirement by typically 35-55%. Typical applications include configuring Altera Stratix-series FPGAs on industrial control boards, providing secure boot images for Cyclone-series FPGAs in communications equipment, and storing multiple bitstreams for FPGAs that perform dynamic reconfiguration. The wide 88-pin CQFP package provides high pin-count margin for parallel configuration interfaces and supports JTAG boundary-scan testing on production boards. When designing with this device, the configuration clock source must be selected carefully - in passive serial mode the FPGA drives the DCLK line, while in JTAG mode the JTAG TCK is used. Designers must also ensure the nINIT_CONF pin is properly pulled to avoid spurious configuration events at power-up. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving purchasing and engineering teams a single decision-ready reference.
EPC18QI100 - 18-Mbit Config Device, 100-pin PQFP | Altera
Altera EPC18QI100 is an 18-megabit serial configuration device designed to configure Altera FPGAs through a serial configuration interface. The EPC18QI100 stores configuration bitstreams in nonvolatile memory and delivers them via a serial data line to the target FPGA at system power-up, replacing multiple parallel PROMs and reducing board area. Housed in a 100-pin Plastic Quad Flat Pack (PQFP) with industrial-grade operating temperature, the device supports in-system programmability via IEEE 1149.1 (JTAG) and is pin-compatible with other members of the Altera EPC16/EPC8 configuration device family. A configuration device (also called a configuration PROM) is a specialized nonvolatile memory IC that stores FPGA configuration bitstreams and serially delivers them to the FPGA at power-on. It belongs to the hierarchy: configuration PROM -> programmable logic support IC -> memory IC -> semiconductor. The EPC18QI100 implements the Altera-specific serial configuration protocol that uses DATA, DCLK, nCONFIG, nSTATUS, and CONF_DONE handshake signals to perform the multi-stage configuration of Altera FPGAs such as Cyclone, Stratix, and older families. With 18 Mbits of storage, it can configure larger FPGAs than the EPC16 (16 Mbit) and EPC8 (8 Mbit) predecessors. Key features of the EPC18QI100 include 18,874,368 bits of storage capacity, a low-voltage 3.3V core supply plus 5V or 3.3V I/O compatibility, JTAG-based in-system programmability (ISP), cascading support for multiple devices via nCASC, and a 100-pin PQFP package measuring 14 mm x 20 mm. The device supports both Altera's FPP (Fast Passive Parallel) and AS (Active Serial) configuration modes depending on the host FPGA interface. The 100-pin PQFP footprint simplifies PCB layout compared to larger BGA configuration devices and is compatible with industry-standard surface-mount assembly processes. Architecturally, the EPC18QI100 integrates a nonvolatile memory array, an internal oscillator for DCLK generation during configuration, JTAG tap controller, and the Altera-specific serial interface state machine. Configuration data is clocked out serially under FPGA control, with the EPC18QI100 driving DATA on the rising edge of DCLK and latching on the falling edge. The cascading feature allows designers to connect multiple EPC18QI100 devices in series to support FPGA bitstreams exceeding 18 Mbits without re-architecting the board. Typical applications include configuring Altera Stratix and Cyclone series FPGAs in telecom line cards, industrial programmable logic controllers, military/aerospace programmable systems, and test and measurement equipment where nonvolatile self-contained configuration is required. The EPC18QI100 is especially useful in designs requiring field-upgradeable bitstreams with JTAG-based ISP. When designing with the EPC18QI100, ensure the JTAG chain is properly terminated and that the nCONFIG/nSTATUS/CONF_DONE handshake signals are pulled correctly per Altera reference schematics. Decoupling should include 0.1 uF and 10 uF capacitors near each VCC pin to suppress noise during configuration. Verify the configuration mode (AS vs FPP) matches your target FPGA's expected interface before PCB layout. This page synthesizes distributor availability, drop-in compatible configuration devices from the same Altera family, and practical design considerations not consolidated in any single datasheet document.
EPC1L120 - Altera/Intel Configuration Device 120 kbit Serial | PLCC-20
The Altera (Intel Programmable Solutions Group) EPC1L120 is a 120 kbit serial configuration memory device designed for loading configuration data into Altera FPGAs and Complex Programmable Logic Devices (CPLDs). Housed in a 20-pin Plastic Leaded Chip Carrier (PLCC-20) package, the EPC1L120 stores the bitstream that programs SRAM-based programmable logic at power-up, supporting ISP (in-system programmability) and the Altera MultiVolt interface. A configuration device is a non-volatile serial memory specifically engineered to hold FPGA/CPLD configuration bitstreams and to manage the configuration sequence (nCONFIG, nSTATUS, CONF_DONE) on power-up. Compared to a generic serial EEPROM or flash, a configuration device handles the FPGA handshaking protocol, supplies data through the dedicated serial data line, and resets the FPGA automatically; it sits in the system hierarchy at configuration memory -> programmable-logic support -> memory IC -> integrated circuit. The EPC1 family belongs to Altera's classic configuration IC lineup introduced alongside the FLEX 6000 and FLEX 8000 series. Key features of the EPC1L120 include 120 kbit user-configurable memory capacity, a 3.3 V or 5 V operating supply with MultiVolt output compatibility to drive 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V target devices, in-system programmability through an IEEE Std 1149.1 JTAG interface, and a low-pin-count serial interface that minimizes board space. The device is reprogrammable up to 100 times, supports cascaded configuration chains for multiple FPGAs, and offers separate JTAG and serial configuration ports. Architecturally, the EPC1L120 integrates a CMOS serial EEPROM array, charge-pump high-voltage generator, JTAG TAP controller, and Altera's proprietary configuration control logic on a single die. The MultiVolt output driver uses an open-drain topology with an external pull-up resistor, allowing the same device to configure FPGAs of any I/O voltage on the same board. Typical applications include storing the configuration bitstream for Altera FLEX 6000, FLEX 8000, MAX 7000S/A/B, and MAX 9000 devices; ISP-capable designs that allow remote field upgrade of logic; and multi-FPGA designs where configuration devices are cascaded. The PLCC-20 through-hole package also makes it suitable for prototype boards and legacy systems. When designing with the EPC1L120, ensure the JTAG chain length does not introduce signal-integrity problems and that the open-drain CONF_DONE line has a proper pull-up to the target supply. Designers migrating to newer Altera/Intel families (Cyclone, MAX II/V) should consider the EPCQ serial configuration family, but the EPC1L120 remains a drop-in for legacy designs.
