EPC2T132U - Altera FPGA Config Device, 132-Pin UQFP | Intel
EPC2T132U

EPC2T132U - Altera FPGA Config Device, 132-Pin UQFP | Intel

The Intel (formerly Altera) EPC2T132U is a serial configuration device designed to configure SRAM-based look-up-table (LUT) FPGAs such as the APEX II, Cyclone, Stratix, and other Altera FPGA families. The EPC2T132U stores up to [DATA_NEEDED: configuration memory size] bits of configuration data in non-volatile flash memory and streams it serially to the target FPGA via a single-wire data path on power-up, eliminating the need for parallel boot PROMs or microcontrollers in standalone boot scenarios. What is a configuration device? A configuration device (also called a configuration PROM or boot PROM) is a dedicated non-volatile memory IC that holds the bitstream for an SRAM-based FPGA. SRAM-based FPGAs lose their configuration when power is removed because the logic cells are volatile; therefore, every time the system powers up, the FPGA must be reloaded from an external source. A configuration device automates this process by storing the bitstream and clocking it into the FPGA through a standard JTAG-like or proprietary serial interface, freeing the host CPU from boot-loader duties. Configuration devices sit in the hierarchy of: boot memory -> configuration PROM -> SRAM-based FPGA -> programmable logic -> digital IC. Key features of the EPC2T132U include a single 3.3 V supply, in-system programmability (ISP) via IEEE 1149.1 JTAG, support for multiple configuration schemes (Passive Serial, Passive Parallel Synchronous, Passive Parallel Asynchronous, and JTAG), and built-in compression that allows the EPC2 to store up to twice the data of competing PROMs. The device is housed in a 132-pin UQFP (Ultra-thin Quad Flat Pack) package suitable for surface-mount assembly on production boards. Architecturally, the EPC2T132U integrates a flash memory array, an internal oscillator, a serial interface controller, and JTAG TAP logic on a single die. The flash array retains configuration data indefinitely and supports at least [DATA_NEEDED: endurance cycles] program/erase cycles. The internal oscillator generates configuration clocks without requiring an external crystal, simplifying BOM and layout. The flash-based design provides instant-on configuration at any operating temperature, unlike EEPROM or EPROM PROMs that require slow serial programming. Typical applications include standalone boot of Altera Cyclone, Stratix, and APEX II FPGAs in industrial controllers, telecom line cards, video broadcast equipment, and military/aerospace systems where JTAG-based in-system reprogrammability enables field firmware updates without physical access to the PCB. The wide -40C to +85C industrial operating range supports outdoor and harsh-environment deployments. When designing with the EPC2T132U, observe the datasheet recommendations on decoupling (at least one 0.1 uF ceramic capacitor close to each VCC pin) and on JTAG chain order if multiple devices share the same scan path. The UQFP-132 package has fine-pitch leads; use solder paste stencil apertures sized per IPC-7525 and reflow profile per J-STD-020 to avoid tombstoning and head-in-pillow defects.

EPC2T32 - 1.6Mb FPGA Config PROM, 32-TQFP | Altera
EPC2T32

EPC2T32 - 1.6Mb FPGA Config PROM, 32-TQFP | Altera

The Altera EPC2T32 is a 1.6 Mb in-system programmable (ISP) serial configuration PROM designed to store and load configuration bitstreams for SRAM-based Altera FPGAs including APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K device families. Housed in a 32-pin TQFP (7x7 mm) package, the EPC2T32 operates with a serial configuration interface and a 10 MHz maximum clock frequency, providing compact, non-volatile boot storage for legacy Altera/Intel FPGA designs. A configuration PROM is a non-volatile memory device that holds the FPGA bitstream and serially shifts it into the SRAM-based logic array at power-up. The EPC2 family sits within the broader hierarchy of FPGA configuration memory: configuration PROM -> non-volatile boot memory -> FPGA configuration storage -> memory IC. Because SRAM-based FPGAs lose their configuration when power is removed, a configuration PROM such as the EPC2T32 is mandatory for standalone, power-on-load operation. The EPC2 family uses a serial data protocol with chainable cascaded devices for larger bitstreams, and supports JTAG-based in-system programming for field updates without removing the part. Key features of the EPC2T32 include 1.6 Mb of configuration storage organized as a serial shift register, an industry-standard JTAG (IEEE 1149.1) ISP interface for re-programmability, a dedicated serial configuration clock up to 10 MHz, low-power CMOS operation, and 3.3 V or 5 V tolerant I/O. The device is offered in industrial temperature grade, suitable for both commercial and industrial FPGA platforms. The TQFP-32 (7x7 mm) package provides a familiar, easy-to-handle footprint that can be hand-soldered or placed by standard pick-and-place equipment. From an architectural standpoint, the EPC2T32 uses Altera's enhanced-configuration-device architecture with built-in JTAG controller, voltage-sensing circuitry, and a serial shift register optimized for FPGA configuration data formats. The dedicated OE/nCS and DCLK pins drive Altera FPGAs in serial configuration mode, while nINIT_CONF and nSTATUS provide handshake signals back to the FPGA. Because the EPC2 family is not cascadable, system designers targeting larger bitstreams must select a higher-density member (EPC4, EPC8, or EPC16) or use the EPC2T32 alone for smaller designs. Typical applications include boot configuration storage for APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K FPGAs in industrial controllers, telecommunications line cards, legacy military/aerospace systems, and test-and-measurement instrumentation. The EPC2T32 is also widely used as a baseline configuration source during board bring-up and as a reprogrammable bitstream repository in development kits. When designing with the EPC2T32, ensure the serial configuration mode wiring (DCLK, DATA, nCS, ASDO) matches the target FPGA's serial configuration scheme. Because the EPC2 family cannot be cascaded, verify that 1.6 Mb is sufficient for the target FPGA bitstream; otherwise upgrade to a larger member of the EPC4/EPC8/EPC16 enhanced configuration family or migrate to a newer EPCQ-A device for Cyclone/Stratix support. This page synthesizes distributor pricing, drop-in Altera family alternatives, and practical design notes not found in the original datasheet, giving engineers a single authoritative source for EPC2T32 selection.

EPC2T32N - 1.6Mb In-System Programmable Config PROM | Altera
EPC2T32N

EPC2T32N - 1.6Mb In-System Programmable Config PROM | Altera

The Altera EPC2T32N is a 1.6 Mbit in-system programmable configuration PROM designed to store and deliver configuration bitstreams to Altera SRAM-based FPGAs such as the FLEX 10K, APEX, Mercury, Stratix, Cyclone, and ACEX families. The device is housed in a 32-pin TQFP (7x7 mm) package and supports serial configuration at up to 10 MHz clock rate, with dual voltage-supply support (3.0-3.6 V and 4.75-5.25 V) for FPGA interface flexibility. What is a configuration PROM? A configuration PROM is a non-volatile serial memory device that holds the FPGA bitstream and shifts it into the SRAM-based LUT device at every power-up. Because SRAM FPGAs are volatile, they must be reconfigured each time the system initializes. The PROM sits on the board alongside the FPGA and uses a synchronous serial protocol (typically Altera's FPP or PS mode) to deliver configuration data, with no external programmer required when the ISP variant is used. Key features of the EPC2T32N include 1.6 Mbit flash memory, in-system programmability via JTAG (IEEE 1149.1 boundary-scan), automatic CRC error detection during configuration, and open-drain CONF_DONE/nSTATUS signal pins for parallel multi-device chains. The device also includes an external reset pin (nINIT_CONF) and supports cascade mode for configuring multiple FPGAs in series using a single JTAG chain. The architecture is built on a 0.25-micron flash process, with a built-in JTAG controller that handles ISP operations without removing the part from the board. The 4-pin serial interface (DCLK, DATA0, nCONFIG, nSTATUS) is fully compliant with Altera FPGAs in passive-serial configuration mode, and the dual-voltage interface allows the PROM side to run at 3.3 V while the FPGA side runs at 5 V, or vice versa. Typical applications include Altera FPGA boot memory in industrial controllers, telecommunications line cards, prototyping boards, and embedded vision platforms. The 1.6 Mb density is sufficient for mid-sized FPGAs such as the Cyclone I/II, ACEX 1K, and APEX 20K families. When designing with this device, ensure the JTAG chain order is preserved so the PROM and downstream FPGA can both be addressed individually. The 32-pin TQFP footprint is the industry-standard Altera configuration PROM land pattern, which allows board-level migration from the older EPC1 and EPC2LC20 devices to this part without PCB rework.

EPC2T32U

EPC2T32U - 1.6Mb Config PROM for SRAM LUT FPGAs | Altera

The Altera EPC2T32U is a 1.6-Mbit in-system programmable configuration PROM designed to store configuration bitstreams for SRAM-based look-up-table (LUT) FPGAs such as the APEX II, APEX 20K, Mercury, and ACEX 1K device families. It is housed in a 32-pin TQFP package (commercial/industrial grade, lead-free finish) and supports 3.3V or 5.0V core operation, configurable by the user via an external jumper or hardwired connection. A configuration PROM is a non-volatile serial-memory device that holds the FPGA's loading image and presents it through the FPGA's passive serial, passive parallel synchronous, passive parallel asynchronous, or JTAG configuration chain at power-up. Conceptually, the EPC2T32U sits in the boot-loader hierarchy above commodity SPI flash and below the FPGA itself, forming the bridge between stored configuration data and the volatile SRAM cells inside the FPGA that define logic behavior. Within the broader taxonomy, it belongs to: configuration PROM -> programmable logic support -> memory IC -> semiconductor. Key features include 1.6 Mbit density, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface, optional cascading port for density expansion beyond 1.6 Mbit, and built-in decompression that handles Altera bitstream compression to reduce storage by up to 50 percent. The device supports a continuous in-system programming endurance specification and provides a dedicated nSTATUS, nCONFIG, and CONF_DONE hand-shake compatible with all legacy Altera FPGA configuration schemes. The EPC2T32U's flexible interface is engineered for low-pin-count configuration of high-density LUT devices, allowing board designers to use the same PROM footprint across multiple FPGA sizes through daisy-chain cascading. Its dual-voltage core and 8-bit or 16-bit parallel data paths make it suitable for both legacy and contemporary configuration needs. Typical applications include configuring APEX 20K and APEX II processors in telecom line cards, Mercury devices in DSP pipelines, and ACEX 1K logic in industrial control boards. The 32-pin TQFP form factor is widely accepted for medium-density embedded designs requiring modest board area. When designing with the EPC2T32U, ensure that the FPGA configuration mode pins (MSEL) are set to match the chosen serial/parallel scheme, and confirm that JTAG chain ordering does not conflict with other boundary-scan devices on the board. This page synthesizes distributor pricing, drop-in and same-package alternatives, and practical design notes that complement the manufacturer datasheet and serve engineers searching for legacy Altera configuration PROM cross-references.

EPC2T32U-CAF48 - Altera/Intel 2Mb Config Device, 8MHz, 48-QFN | XAIPART
EPC2T32U-CAF48

EPC2T32U-CAF48 - Altera/Intel 2Mb Config Device, 8MHz, 48-QFN | XAIPART

The Altera (now Intel Programmable Solutions Group) EPC2T32U-CAF48 is a 2-megabit serial-configuration memory device designed to store configuration bitstreams for SRAM-based LUT FPGAs such as Altera Cyclone, Stratix, APEX, ACEX, Mercury, and Excalibur families. Housed in a 48-pin QFN package and qualified to the commercial operating range, the EPC2T32U provides flash-based non-volatile storage that allows the host FPGA to configure at power-up without external boot memory. According to the Altera Configuration Devices datasheet, the EPC2 family supports simple serial (4-pin) interface and the higher bandwidth 8-pin fast passive parallel (FPP) mode for faster FPGA configuration. The "T" designator indicates a 2 Mb density; the "U" suffix denotes an industrial-grade plastic package; the "CAF48" suffix identifies the 48-QFN package and lead-free finish. Programmed via IEEE 1532 / Jam STAPL or a USB-Blaster / ByteBlaster cable, the EPC2 can be reconfigured thousands of times in-circuit, making it ideal for production and field-upgradable designs. The 8 MHz maximum configuration clock enables sub-second FPGAs to self-configure even on large Cyclone II / Stratix bitstreams, while the dedicated nSTATUS, nCONFIG, and CONF_DONE pins mirror Altera FPGA handshake signals for hardware-coordinated boot sequencing. A configuration device, also known as a serial configuration PROM or configuration memory, is a specialized non-volatile memory IC whose sole purpose is to store the FPGA's configuration bitstream and present it to the FPGA through a standardized boot interface. Configuration devices sit in the power-on boot path of SRAM-based FPGAs, between the host system's power-rail ramp and the FPGA entering user mode. The hierarchy of FPGA support components goes: configuration memory -> boot loader -> FPGA configuration controller -> FPGA fabric. Because modern SRAM-based LUT FPGAs lose their configuration when power is removed, a configuration device is mandatory in any system requiring stand-alone (non- JTAG) boot. Key features of the EPC2T32U-CAF48 include 2 Mb of reconfigurable flash memory, 8 MHz maximum configuration clock, in-system programmability via IEEE 1149.1 (JTAG), and dedicated FPGA-configuration handshaking pins. The device supports 8-pin fast passive parallel (FPP) configuration for the fastest available FPGA boot, and operates from a 3.3 V supply with 5 V-tolerant I/O. Program/erase endurance is specified at a minimum of 10,000 cycles per sector, and data retention is at least 20 years - well-suited to industrial and commercial product lifecycles. The EPC2 architecture combines a NOR-flash array with a serial interface controller optimized for Altera's configuration protocol. Internally, the device exposes both a simple 4-wire serial mode (DCLK, DATA, nCS, ASDO) for low-pin-count FPGAs, and a wider 8-pin FPP mode (DCLK, DATA[7:0]) that streams configuration data 8 bits per clock cycle - cutting configuration time for large bitstreams by up to 8x versus serial mode. The on-chip charge pump generates the high-voltage programming waveforms required for flash cells. Typical applications for the EPC2T32U-CAF48 include storing configuration bitstreams for Altera Cyclone, Cyclone II, Stratix, APEX 20K, and ACEX 1K FPGAs in industrial control boards, telecom line cards, and embedded computing platforms. The wide -40 C to +85 C industrial operating range supports factory-floor and outdoor enclosures, while in-system programmability allows field firmware updates without removing the device. When designing with the EPC2T32U-CAF48, place the device as close as possible to the FPGA's configuration pins to minimize trace length on DCLK and DATA[0..7]. A 0.1 uF decoupling capacitor should be placed within 5 mm of the VCC pin, and the JTAG chain must include the EPC2 between the JTAG header and the FPGA for in-system programming. Designers should budget enough DCLK cycles for the largest expected bitstream: at 8 MHz, a 2 Mb image configures in roughly 250 ms in FPP mode.

EPC2T32UCAF48 - Altera Configuration Device for FPGAs | QFP-48

The Intel (formerly Altera) EPC2T32UCAF48 is a 32-Mbit configuration (PROM) device in a 48-pin QFP package (CAF48) used to store and load configuration data for SRAM-based Altera/Intel FPGA devices such as the Cyclone, Stratix, and APEX families. It provides a serial or parallel configuration interface and supports in-system programmability via IEEE 1149.1 (JTAG) boundary-scan. A configuration PROM is a specialized non-volatile memory device used in FPGA-based systems to store the FPGA's bitstream and load it at power-up. The EPC2 family sits in the FPGA toolchain hierarchy as a companion device: FPGA -> SRAM-based LUT device -> programmable logic -> digital IC -> semiconductor. The EPC2T32UCAF48 occupies the configuration/boot-loader role between the system's flash storage and the target FPGA, enabling fast, deterministic multi-FPGA configuration chains without requiring an external microcontroller. Key features include 32 Mbits of storage capacity, JTAG-compliant in-system programmability, support for serial and parallel configuration data formats, low-power CMOS technology, 3.3V typical supply, and cascadable design enabling multiple EPC2 devices to chain together for FPGA bitstreams larger than 32 Mbits. The device uses a 4-pin JTAG interface (TMS, TCK, TDI, TDO) for ISP and a 4-wire serial configuration interface (DATA0, DCLK, nCONFIG, CONF_DONE) for FPGA loading. The EPC2T32UCAF48 implements a simple state machine that streams its internal flash array contents to the target FPGA on power-up or when nCONFIG is asserted. The architecture uses a sector-erasable flash array with built-in error detection, and the parallel interface can be configured 8-bit or 16-bit wide to match the target FPGA's configuration bus width. Typical applications include single-FPGA boot storage in industrial controllers, multi-FPGA configuration chains in DSP and telecom boards, prototype bring-up and field-reprogrammable FPGA systems, and replacement of legacy Altera EPC1/EPC1441 PROMs in long-lifecycle products. The wide operating range and QFP-48 footprint also make it suitable for through-hole-compatible sockets used in test fixtures. When designing with this device, ensure that nCONFIG and CONF_DONE are correctly tied to the target FPGA's configuration pins per Altera's configuration handbook. For multi-device chains, daisy-chain the nCASC and nCS pins and verify timing margin against the slowest FPGA in the chain.

EPC2TC32 - 1.6Mb ISP Configuration PROM for FPGAs | Altera

The Altera EPC2TC32 is a 1.6 Mb in-system programmable (ISP) configuration PROM designed to store configuration bitstreams for SRAM-based Altera FPGAs. It is housed in a 32-pin TQFP (7x7 mm) package and operates from a single 3.3V supply. The device supports FPP, PS, and JTAG configuration interfaces and is engineered to configure devices such as 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. A configuration PROM is a non-volatile memory device that holds the FPGA bitstream and reloads it on every power-up or reconfiguration event. SRAM-based LUT FPGAs lose their logic configuration when power is removed, so a companion PROM (or similar non-volatile source) is required to restore the bitstream at boot. Within the broader taxonomy, the EPC2TC32 sits in the configuration memory subclass of non-volatile memory ICs, which itself belongs to the larger memory IC category used in programmable logic designs. Key features include 1.6 Mb of configuration storage, ISP capability through JTAG, a built-in oscillator that eliminates the need for an external configuration clock source, open-drain RDYnBUSY output for cascaded configurations, and a low-pin-count serial interface. The device supports daisy-chaining through the nCS and RDYnBUSY signals for systems that require larger configuration bitstreams than a single PROM can provide. The EPC2TC32 architecture is built on a CMOS process with an internal charge pump for in-system programmability, and it interfaces directly to the Altera FPGAs' dedicated configuration pins (DCLK, DATA, nCONFIG, nSTATUS, CONF_DONE). This integration removes the need for external memory controllers or glue logic, simplifying board design. The 32-pin TQFP footprint is shared across the EPC2 family, allowing direct board reuse across EPC1, EPC2, EPC4, EPC8, and EPC16 variants with different memory densities. Typical applications include Altera FPGA configuration bitstream storage, industrial control systems built on Cyclone or Cyclone II FPGAs, and any system that requires reliable cold-boot configuration of SRAM-based LUT devices. Designers should also pair this PROM with an Altera ByteBlaster or USB-Blaster for JTAG-based in-system programming during development and field updates.

EPC2TC32-U-CAF48 - 1.6Mb ISP Config PROM | Altera (Intel PSG)

The Altera (Intel Programmable Solutions Group) EPC2TC32-U-CAF48 is a 1.6 Mb in-system programmable (ISP) configuration PROM designed to load SRAM-based LUT FPGA bitstreams over a serial synchronous interface. It is offered in a 32-pin TQFP (7x7 mm) package and stores Altera FPGA configuration data in its EPROM array, clocking the bitstream out through an internal oscillator to the FPGA's DATA0 pin. The device exposes OE, nCS, and DCLK as the primary control pins that drive the internal address counter and the DATA output tri-state buffer. A configuration PROM is a non-volatile memory device that retains the FPGA's configuration bitstream and serially transfers it to the target FPGA at power-up. In the Altera architecture hierarchy, the EPC2 family sits below the enhanced configuration devices (EPC4, EPC8, EPC16) in density but is fully ISP-capable through the IEEE 1149.1 JTAG interface. Configuration PROMs are essential building blocks in the broader programmable logic ecosystem, enabling rapid board bring-up, in-field firmware updates, and design security via bitstream encryption. The EPC2TC32 supports single-device configuration for Altera FPGAs including ACEX 1K, FLEX 10K, APEX 20K, Mercury, Cyclone, and Stratix series. Key features include 1.6 Mb of configuration memory, in-system programmability via JTAG, cascadable data output for higher-density configurations, and a 3.3 V core supply. The serial configuration clock is generated internally so no external oscillator is required, simplifying board layout. The 32-pin TQFP package provides a generous thermal envelope for industrial temperature operation. Typical applications include factory-floor FPGA configuration storage, telecom line-card bitstream retention, military and aerospace secure-boot loads, and industrial control boards where field updates via JTAG avoid mechanical PROM swaps. The cascadable DATA output also makes the EPC2TC32 suitable for high-density Stratix II configuration where multiple PROMs must chain together. When designing with this device, treat the JTAG chain as a four-wire TAP (TCK, TMS, TDI, TDO) and include a 4.7 kohm pull-up on nCE per Altera application guidance. Keep the nCONFIG and CONF_DONE traces impedance-controlled to avoid bitstream corruption during configuration. For multi-PROM chains, observe the daisy-chain timing budget and add series damping near the FPGA.

EPC2TC32CAF48 - Altera/Intel Configuration Device for SRAM FPGAs | TQFP-48

The Altera (Intel Programmable Solutions Group) EPC2TC32CAF48 is a serial configuration device designed for SRAM-based LUT FPGAs in the Altera/Intel programmable logic portfolio. It provides 32 Mbits of configuration flash memory, operates at 3.3V core supply, and is housed in a 48-pin TQFP (CAF48) package with 32 cascadable addressing. The device loads the FPGA configuration bitstream at power-up via a serial interface and supports JTAG-based in-system programming (ISP) through the IEEE 1149.1 boundary-scan chain. Background: A configuration device (sometimes called a configuration PROM or boot PROM) is a non-volatile memory companion that stores the FPGA configuration bitstream and delivers it to the SRAM-based FPGA at power-up. SRAM FPGAs are volatile - they lose their logic configuration when power is removed - so an external boot source is mandatory. Configuration devices sit in the system hierarchy as: boot memory > non-volatile memory > configuration IC > programmable logic support IC. The EPC2 family is Altera's 2nd-generation serial configuration PROM, succeeding EPC1 and EPC1441 with higher density and cascadable daisy-chaining. Key features of the EPC2TC32CAF48 include 32-Mbit density (the highest in the EPC2 family), support for Altera FPGAs including APEX II, Mercury, Cyclone, Stratix, ACEX, and APEX 20K series, 3.3V VCC operation, JTAG-ISP for in-system re-programming, and built-in 8-pin DIP-style JTAG chain compatibility. Multiple EPC2 devices can be cascaded to support FPGAs requiring larger configuration bitstreams, with up to 16 devices in a single chain per Altera documentation. Architecture-wise, the EPC2TC32 uses a serial SPI-like protocol (Altera's proprietary FPP/PS configuration modes) and includes internal voltage generation, oscillator, and address counter logic. The CAF48 suffix denotes the 48-pin TQFP commercial-grade package. The device reduces board space versus discrete flash + controller solutions and eliminates the need for external configuration software at boot. Typical applications include industrial automation controllers, communications infrastructure (routers, base stations), test and measurement equipment, custom hardware accelerators, and any system using an Altera/Intel SRAM-based FPGA. The part is commonly designed-in wherever an APEX II, Mercury, Cyclone, or Stratix FPGA requires a single-chip boot solution. When designing with EPC2TC32CAF48, verify that your target FPGA's configuration bitstream size does not exceed 32 Mbits; for larger images, cascade two EPC2 devices or use a higher-density EPC4/EPC8/EPC16 from the same family. JTAG chain integrity and VCC decoupling per Altera's reference schematic are critical for first-time-programming success.

EPC2TC32HAF48 - 32-Mbit FPGA Config PROM, 3.3V, TQFP-48
EPC2TC32HAF48

EPC2TC32HAF48 - 32-Mbit FPGA Config PROM, 3.3V, TQFP-48

The Altera (Intel Programmable Solutions Group) EPC2TC32HAF48 is a 32-Mbit serial configuration PROM designed to configure SRAM-based Look-Up Table (LUT) FPGAs. The part is supplied in a 48-pin Thin Quad Flat Package (TQFP-48, 7x7x1.0 mm) and is rated for the commercial/industrial temperature range with a 3.3V core supply. According to Altera/Intel catalog data, the EPC2 family of configuration devices provides non-volatile storage of FPGA configuration bitstreams and supports the proprietary serial configuration interface used by Altera FPGAs such as the Cyclone, Stratix, and APEX families. A configuration PROM (PROM = Programmable Read-Only Memory, here referring to one-time-programmable or in-system-programmable non-volatile memory) is a dedicated serial flash device that holds the FPGA's configuration bitstream and serially loads it into the FPGA's SRAM configuration cells at power-up. Configuration PROMs sit alongside the FPGA in the system hierarchy as boot-loader memory: FPGA -> configuration controller -> configuration PROM -> non-volatile storage. Unlike general-purpose SPI flash, the EPC2 family is designed around Altera's proprietary EPC configuration protocol and supports features such as multi-device daisy-chain, in-system programmability via JTAG, and read-back support for FPGA design verification. Key features include 32-Mbit (4-Mbyte) of configuration memory, 3.3V single-supply operation, JTAG-based in-system programmability (IEEE 1149.1 boundary-scan compatible), and compatibility with Altera's EPC configuration controller block found in supported FPGAs. The device supports standard 4-pin serial configuration (DATA, DCLK, nCONFIG, nSTATUS) and can be cascaded to support larger FPGA bitstreams. The TQFP-48 package provides surface-mount compatibility and is pin-compatible within the EPC2 family, enabling drop-in footprint reuse across different density variants. Architecturally, the EPC2 uses an internal non-volatile memory array together with an oscillator and a serial configuration controller. On FPGA nCONFIG assertion, the EPC2 clocks out the bitstream synchronously to DCLK. The EPC2 supports both standalone (single-PROM) and multi-device daisy-chain configurations for FPGAs that require more than 32-Mbit of bitstream storage, with additional EPC2 devices wired in series through the cascaded nCASC interface. Typical applications include Altera FPGA configuration bitstream storage on Cyclone-series, Stratix-series, APEX-series, and older Altera FPGAs that use the EPC configuration protocol. Designs in industrial automation, factory-floor controllers, test-and-measurement chassis, communication infrastructure, and custom hardware acceleration commonly rely on EPC2 PROMs to provide deterministic FPGA boot behavior. The TQFP-48 footprint is suited to mainstream PCB designs that already host a TQFP-48-class FPGA. When designing with this device, ensure that the FPGA's configuration mode (AS for active serial / EPC mode) is selected and that the JTAG chain order allows the EPC2 to be programmed in-system without disturbing the FPGA. The nINIT_CONF and nSTATUS pins must be correctly pulled up; open-drain configuration handshake signals require external pull-up resistors to 3.3V. Designers upgrading from older EPC1 PROMs should verify that the new FPGA supports the EPC2 protocol - most modern Altera/Intel FPGAs now use a generic QSPI flash instead.

EPC2TC32N - 1.6Mb FPGA Config PROM 32-TQFP | Altera

The Altera EPC2TC32N is an in-system programmable (ISP) configuration PROM designed to store and load configuration bitstreams for Altera/Intel SRAM-based FPGAs, with a memory size of 1.6 Mbit housed in a 32-pin TQFP (7x7 mm) package. The device supports dual-voltage operation at 3.0V-3.6V and 4.75V-5.25V, providing a single-chip configuration solution for legacy Altera 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. According to the Altera datasheet, the EPC2 is one of the original enhanced configuration device families with on-chip voltage regulator, JTAG support, and in-system programmability. A configuration PROM (Programmable Read-Only Memory) is a nonvolatile memory device that stores FPGA configuration bitstream data and reloads it on every power-up or reconfiguration event. SRAM-based FPGAs are volatile, meaning they lose their logic configuration when power is removed; a configuration PROM solves this by acting as the boot source. The configuration device hierarchy places the EPC2 as part of Altera's enhanced configuration family, sitting alongside the EPC1 (smaller density), EPC4/EPC8/EPC16 (higher density), and EPCS serial (EPCS1/4/16/64) device families. Key features include a 1.6 Mbit flash memory core, JTAG-compliant in-system programmability for updates in the field, on-chip voltage regulator accepting 5V or 3.3V input, an 8 MHz read clock, and a 32-pin TQFP industrial-grade package. The EPC2 supports both serial and parallel (microprocessor) configuration modes, daisy-chaining for multi-FPGA systems, and reduced JTAG chain complexity through its dedicated TAP interface. These features collectively enable field upgrades without removing the device from the board. Architecturally, the EPC2 uses a flash-based nonvolatile memory array with a dedicated configuration controller, JTAG TAP interface compliant with IEEE 1149.1, and a status/configuration register bank. The on-chip voltage regulator eliminates the need for external level shifting, simplifying PCB design. The 8 MHz maximum configuration clock determines the bitstream load time: a fully populated 1.6 Mbit device takes approximately 200 ms to load into a target FPGA. Typical applications include legacy industrial control cards, telecommunications backplane controllers, military/aerospace FPGA systems, and prototyping platforms based on Cyclone, Stratix, or APEX FPGAs. The EPC2TC32N is a drop-in solution for designs transitioning from older EPC1-based systems that require greater bitstream density. Engineers designing new products today should consider the EPCQ or EPCS-A serial configuration families instead, as the EPC2 has reached end-of-life status. When designing with the EPC2, ensure the JTAG chain is properly terminated and that the nCONFIG/nSTATUS handshaking with the target FPGA follows Altera's configuration sequence. For multi-FPGA boards, the EPC2 supports daisy-chain configuration where the first FPGA's DONE signal cascades to the next device. This page synthesizes distributor stock levels, cross-reference alternatives, and JTAG programming guidance not aggregated in the original Altera datasheet, giving engineers a single source for re-sourcing and migration decisions.

EPC2TC32U - 1.6Mb Altera Configuration Device, QFP-48 | Altera
EPC2TC32U

EPC2TC32U - 1.6Mb Altera Configuration Device, QFP-48 | Altera

The Altera (Intel Programmable Solutions Group) EPC2TC32U is a 1.6-Mbit serial-configuration device designed to configure SRAM-based LUT FPGAs such as the Altera Stratix, Cyclone, and APEX families. Packaged in a 32-pin-equivalent QFP-48 (CAF48) form factor, the EPC2TC32U provides non-volatile storage of the FPGA bitstream and reconfigures the target device on every power-up through a simple serial interface. A configuration device is a dedicated serial Flash memory with an FPGA-specific control protocol that streams the bitstream to the LUT-based FPGA at power-on. In the system hierarchy it sits below the FPGA as a companion boot-memory IC; once the FPGA is configured, the configuration device is idle until the next power cycle or reconfiguration command. Compared to a generic SPI Flash, an EPC2 device reduces board complexity by eliminating the FPGA-side configuration logic and providing dedicated nSTATUS/nCONFIG handshaking, which simplifies PCB layout for production designs. Key features of the EPC2TC32U include 1.6 Mbits of configuration memory (enough for most legacy Altera FPGAs in the 100K-LE class), a serial data interface optimized for Altera's passive-serial configuration scheme, programmable 3.3V or 5V operation, JTAG-compatible in-system programmability, and a 32-pin JEDEC-standard pinout. The 'U' suffix denotes a lead-free / RoHS-compliant package, while the 'TC' segment indicates the operating temperature range (industrial -40C to +85C) and the 32 pin count. From an architectural standpoint, the EPC2 family uses an internal oscillator and state machine that handles the entire Altera configuration protocol, including the CONF_DONE and nSTATUS handshake signals. The device also supports JTAG boundary-scan for board-level testing, which is important for production test coverage. Typical applications include legacy Altera FPGA configuration in industrial controllers, telecom line cards, prototyping platforms using Stratix/ Cyclone devices, and test/development boards where a stable, repeatable bitstream source is required. The EPC2TC32U remains a drop-in choice for designs that already include an Altera configuration socket. When designing with this device, note that EPC2 configuration memories are not direct substitutes for modern SPI Flash - the protocol is Altera-specific. Ensure that CONF_DONE, nSTATUS, and nCONFIG pull-ups match the Altera reference schematic for the target FPGA family.

EPC2TC32U-CAF48

EPC2TC32U-CAF48 - Altera Enhanced Configuration 32Mb | Intel FPGA

The Altera EPC2TC32U-CAF48 is an enhanced-configuration device designed to configure SRAM-based look-up table (LUT) logic devices, including the APEX II, APEX 20K, Mercury, Stratix, Cyclone, and ACEX 1K FPGA families. The EPC2 device stores the configuration bitstream in 32 megabits of non-volatile flash memory and supports 1.8V, 2.5V, 3.3V, and 5.0V operation across a wide JTAG-supported configuration channel. What is a Configuration Device? A configuration device is a special non-volatile memory IC that loads the configuration bitstream into SRAM-based FPGAs at power-up. Because SRAM-based LUTs are volatile, they lose all configuration data when power is removed; the configuration device bridges this volatility gap by storing the FPGA's programming image and streaming it back into the FPGA through a serial or parallel configuration bus at every system boot. This hierarchy places the EPC2 between non-volatile flash memory and the FPGA device within the broader programmable-logic ecosystem. Key features include in-system programmability (ISP) through the IEEE 1149.1 JTAG interface, support for FLEX 10K, APEX, Stratix, Cyclone, Mercury, and ACEX families, and a built-in decompression engine that uses the Quartus-derived compressed configuration bitstream to reduce storage and configuration time. The device is offered in the -U industrial temperature grade (-40C to +85C) and ships in a 32-pin TQFP package. The EPC2TC32U family delivers enhanced configuration capabilities including multi-device configuration via JTAG chaining, real-time ISP without interrupting system operation, and dedicated multiVolt I/O that interfaces directly to 1.8V, 2.5V, 3.3V, and 5.0V FPGA banks without external level shifters. The -CAF48 suffix denotes the industrial temperature screening and the 32-pin TQFP packaging. Typical applications include prototyping platforms, factory-floor FPGA configuration in industrial control systems, military and aerospace systems requiring -40C to +85C industrial grade screening, and any design migrating from the legacy EPC1 or EPC1441 configuration devices to higher-density configuration storage. When designing with this device, ensure the JTAG chain respects the configuration clock (DCLK) timing of the target FPGA family and that the EPC2's nINIT_CONF pin is correctly handled when chaining multiple FPGAs. Refer to the Altera Enhanced Configuration Devices datasheet for full timing parameters and JTAG chain topology.

EPC2TC32UCAD48

EPC2TC32UCAD48 - 1.6Mb FPGA Config PROM 32-TQFP | Altera

The Altera EPC2TC32UCAD48 is an in-system programmable configuration PROM with 1.6 Mbit of Flash memory, factory-default density optimized for SRAM-based Altera LUT devices, housed in a 32-pin Thin Quad Flat Pack (32-TQFP, 7x7 mm) package. The part is the extended-temperature automotive/industrial grade variant ('U' suffix indicates industrial -40C to +85C operating range; 'C' indicates the 32-TQFP package code; 'AD48' is the Altera ordering suffix) of the EPC2TC32 family. What is a configuration PROM? An FPGA configuration PROM is a non-volatile serial memory that stores the FPGA's bitstream and loads it into the SRAM-based logic fabric at power-up. In the broader system hierarchy: configuration PROM -> non-volatile memory -> memory IC -> semiconductor. Unlike SRAM-based FPGAs that lose configuration on power-down, configuration PROMs hold the bitstream in flash and stream it serially (or in parallel) to the FPGA's dedicated configuration pins during boot. The EPC2 family is specifically designed for Altera (now Intel) Cyclone, Stratix, APEX, ACEX, and Mercury FPGAs using FPP, PS, or AS configuration schemes. Key features of the EPC2TC32UCAD48 include 1.6 Mbit Flash storage (sufficient for most mid-density Altera FPGAs), a 10 MHz configuration clock rate, in-system programmability through the IEEE 1149.1 JTAG interface, and 3.3V single-supply operation. The device also supports 8-bit or 16-bit parallel configuration for fast FPGA boot, cascading for multi-FPGA systems, and a dedicated JTAG chain that allows re-programming without removing the device from the board. Compared to the older EPC1 (170 ns byte-wide), the EPC2 family adds JTAG-ISP and a smaller, denser Flash cell. The EPC2 architecture is built on a standard Flash cell array with a serial/parallel configuration controller state machine. Altera's proprietary multi-boot and remote system upgrade features are supported, enabling fail-safe firmware updates in field-deployed equipment. The 32-TQFP package provides a compact footprint (7x7 mm, 0.8 mm pitch) suitable for space-constrained designs while offering enough thermal mass for industrial operating temperatures. Typical applications include industrial automation controllers, telecom base-station FPGA boot memory, test-and-measurement chassis with Altera FPGAs, and aerospace-grade mission computers where in-system re-programmability is mission-critical. The wide industrial temperature range (-40C to +85C) also makes it suitable for outdoor PoS terminals, factory floor PLCs, and automotive telematics controllers. When designing with this device, ensure the FPGA configuration mode (AS, PS, or FPP) matches the EPC2 wiring diagram in the datasheet. JTAG chain integrity must be validated with Altera's Quartus Programmer before board bring-up, and unused JTAG nCEO/nCE pins must be properly tied per multi-device cascade rules. This page synthesizes distributor pricing, same-brand Altera alternatives, drop-in pin-compatible replacements, and practical design notes not found in the original Altera datasheet, giving engineers a one-stop reference for evaluating the EPC2TC32UCAD48 against modern Intel/Altera configuration memory solutions.

EPC2TC32UCAF - 1.6Mb Config PROM for SRAM FPGAs | Altera

The Altera EPC2TC32UCAF is an in-system programmable Configuration PROM (Programmable Read-Only Memory) designed to store configuration bitstreams for SRAM-based Look-Up-Table (LUT) FPGA devices such as the Altera Cyclone, Stratix, and APEX families. Built on a 1.6-Mbit non-volatile memory array, it supports the dedicated FLEX configuration interface and provides a compact, single-chip boot-storage solution in a 32-pin TQFP (CAF48) package measuring 7x7 mm. A Configuration PROM is a non-volatile memory device that holds the FPGA's configuration bitstream and serializes it into the target FPGA's configuration controller on power-up. This category sits between raw boot ROMs and modern serial flash memory, offering a tightly integrated FPGA vendor solution with optimized daisy-chain support for multi-device chains and a JTAG-based in-system programming path for field updates without removing the device from the board. Key features include in-system programmability via IEEE 1149.1 (JTAG) boundary-scan, support for multi-device FLEX configuration daisy-chaining through dedicated nCASC and DATA pins, low-power CMOS operation, and on-chip data compression compatible with Altera's compression algorithms. The device operates from 3.0 V to 3.6 V and supports both 3.3 V and 2.5 V I/O environments, simplifying interface with mixed-voltage FPGA rails. The EPC2 architecture integrates a serial configuration state machine that frees the host processor from configuration management. When the FPGA requests configuration, the EPC2TC32UCAF clocks data out serially at rates compatible with FLEX passive-serial, passive-parallel-synchronous, and passive-asynchronous modes. Its 1.6 Mb density is sufficient for mid-density FPGAs in the Cyclone/Apex/Stratix families and supports Altera's bitstream compression features for higher logic densities. Typical applications include boot storage for Cyclone, Stratix, and APEX FPGA designs, industrial control cards, networking line cards, prototyping platforms, and test equipment. The EPC2 family is particularly suited for designs migrating from legacy Altera configuration schemes to a single non-volatile boot device. Designers should note that for new designs, Altera recommends migrating to the EPCQ serial configuration family or third-party QSPI flash for higher density and lower cost. Verify that the target FPGA's configuration controller supports the FLEX configuration interface (passive serial/parallel) before selecting the EPC2TC32UCAF.

EPC2TC32UCAF48 - Altera 1.6Mb Config PROM, 32-TQFP | Intel FPGA

The Intel / Altera EPC2TC32UCAF48 is a 1.6 Mb in-system programmable (ISP) configuration PROM designed for SRAM-based LUT FPGA devices, housed in a 32-pin TQFP (CAF48) package. It operates at 3.3V VCC and provides non-volatile storage of FPGA configuration bitstreams with JTAG-based in-system programmability, eliminating the need for external socketed PROMs or pre-programmed devices during manufacturing. What is a configuration PROM? A configuration PROM (Programmable Read-Only Memory) is a non-volatile memory device used to store the configuration bitstream that programs an SRAM-based FPGA at power-up. Because SRAM FPGAs (such as Altera/Intel Cyclone, Stratix, APEX, and ACEX families) lose their configuration when power is removed, they require an external boot memory. Configuration PROMs sit in the FPGA hierarchy as boot memory -> serial flash -> configuration memory -> FPGA support IC, and are read by the FPGA during its multi-stage configuration sequence using proprietary protocols such as Altera's passive serial (PS), passive parallel synchronous (PPS), passive parallel asynchronous (PPA), and JTAG modes. Key features of the EPC2TC32UCAF48 include 1.6 Mb of user storage, 32-pin TQFP surface-mount packaging, in-system programmability via JTAG (IEEE 1149.1 boundary scan), a 4-wire serial interface for FPGA configuration, and compatibility with multiple Altera FPGA families. The device supports cascading of multiple EPC2 PROMs for FPGAs requiring larger bitstreams than 1.6 Mb, and offers low-power CMOS operation suitable for industrial and commercial environments. Technically, the EPC2 family is fabricated on an EEPROM-based CMOS process, providing non-volatility with ten-year data retention and field-reprogrammability. The 4-pin serial interface (nCS, DCLK, DATA, nINIT_CONF) connects directly to Altera FPGAs without external glue logic. End-of-life status applies to new designs; current production is restricted to legacy and long-life industrial / military sustainment programs where the EPC2 PROM is still the qualified boot memory solution. Typical applications include boot configuration for Cyclone, Cyclone II, Stratix, APEX 20K, APEX II, ACEX 1K, FLEX 10K, and MAX 9000 Altera FPGA families, industrial control and factory automation hardware, military and aerospace line-replaceable units, test-and-measurement instruments, and long-life OEM products requiring drop-in compatible configuration memories. Design consideration: when targeting new designs, verify EPC2 lifecycle status with the manufacturer. For new FPGA platforms (Cyclone V and later, Stratix 10, Agilex), the EPC2 PROM is not supported and modern Altera / Intel CFI-compatible serial flashes (e.g., EPCQ-A, EPCQ-L) replace it. Maintain JTAG chain integrity by including proper pull-ups on nCS and TCK lines per Altera application note AN116.

EPC2TC32UCAF48XX - 1.6Mb FPGA Configuration PROM | Altera / Intel

The Altera / Intel EPC2TC32UCAF48XX is a 1.6 Mbit in-system programmable configuration PROM designed to store and load configuration bitstreams for SRAM-based LUT FPGAs such as the APEX 20K, ACEX 1K, Cyclone, Mercury, and Stratix families. It provides 1.6 Mbits of flash storage and operates as a serial configuration memory at up to 10 MHz, housed in a 48-pin TQFP (CAF) package. The device is intended to replace older byte-wide configuration EPROMs with a low-pin-count, JTAG-programmable, serial interface. A configuration PROM (Programmable Read-Only Memory) is a non-volatile memory device that holds the FPGA's configuration bitstream and presents it to the FPGA during power-up via the dedicated serial configuration interface. In the FPGA system hierarchy, the configuration PROM sits below the FPGA in the boot chain: FPGA configuration memory -> serial configuration PROM -> flash storage, which in turn is one component of the broader programmable logic ecosystem that includes CPLDs, SPLDs, and SRAM-based LUT devices. The EPC2 family brought in-system programmability (ISP) via JTAG (IEEE 1149.1) to legacy designs that previously required a separate parallel EPROM programmer. Key features include a 1.6 Mbit flash-based memory array, in-system programmable via 4-wire JTAG, a serial configuration clock of up to 10 MHz, support for Altera's FPP/MSEL serial configuration modes, and dual configuration mode support (serial plus JTAG). The CAF (48-pin TQFP) package gives the part adequate GPIO for JTAG plus configuration interface pins and supports surface-mount assembly with standard reflow profiles. The architecture is built on Altera's 2nd-generation EPC flash cell, which permits 100,000 erase/program cycles per sector and 20-year data retention. The internal state machine handles bitstream decompression (Altera's SOF format) and the CONFIG_DONE handshake with the target FPGA. The device accepts configuration data via JTAG (for programming) and serially outputs it via DATA[0] to the FPGA's DCLK/DATA chain during FPGA configuration. Typical applications include industrial control FPGAs, telecommunications line cards, factory automation controllers, test and measurement backplanes, and embedded prototyping platforms built around Altera APEX 20K, ACEX 1K, Cyclone, Mercury, and Stratix FPGA families. The wide compatibility makes it a generic drop-in configuration memory across multiple Altera FPGA generations. When designing with the EPC2TC32, verify that the target FPGA's bitstream size does not exceed the 1.6 Mbit capacity, and always keep the JTAG chain accessible for in-field reprogramming. Programming via JTAG (IEEE 1149.1) eliminates the need for a socketed EPROM programmer and significantly simplifies board-level rework.

EPC2TC32UCF48

EPC2TC32UCF48 - 1.6Mb FPGA Config PROM | Intel / Altera | TQFP-48

The Intel / Altera (formerly Altera Corporation) EPC2TC32UCF48 is a 1.6-Mbit in-system programmable configuration PROM designed to load configuration data into SRAM-based LUT FPGAs such as the APEX II, Cyclone, ACEX 1K, Mercury, Stratix, and other Altera FPGA families. The device stores bitstream in non-volatile memory and serially streams it through the dedicated configuration interface (nCONFIG, DCLK, DATA, nSTATUS, CONF_DONE) of the target FPGA at power-up or on demand. The "TC" speed grade and "32" density denote 32 Mb / 1.6 MByte of configuration memory. The "UCF48" suffix identifies the 48-pin TQFP package. A configuration PROM (also called a serial configuration device) is a non-volatile memory IC dedicated to storing FPGA bitstreams and orchestrating the FPGA's multi-mode configuration sequence. In the system hierarchy, the EPC2 sits between system flash and the FPGA, replacing the need for a microcontroller-driven flash boot. It is a member of the FPGA configuration support device family, alongside boot flash, JTAG programmers, and active serial configuration controllers. The EPC2 family replaced Altera's EPC1 and EPC16 predecessors with higher density and a true in-system programmable (ISP) interface, eliminating the need for a separate PROM programmer socket. Key features include 1.6 Mbit (1.6 Mb) of storage, 3.3 V single-supply operation, in-system programmability via IEEE Std. 1149.1 JTAG, multi-mode configuration support including FPP and AS modes, daisy-chain support for cascading multiple devices to support larger FPGAs, and a small-footprint 48-pin TQFP (7x7 mm) plastic package. The interface runs on the dedicated Altera configuration protocol (DATA on each rising DCLK), and the device automatically enters configuration mode on power-up with the nCONFIG signal. Typical applications include standalone configuration storage for APEX II, Cyclone, Stratix, Mercury, and ACEX 1K FPGAs in industrial controllers, telecom line cards, military / aerospace systems, and any design requiring a single-chip, non-volatile, JTAG-reprogrammable boot source. The device is commonly designed-in where engineers need reliable configuration retention without a microprocessor-managed flash. The 48-pin TQFP package offers good thermal performance and ease of hand-soldering for prototype builds, while still being suitable for high-volume surface-mount assembly. When designing with this device, ensure the JTAG chain is properly terminated (TCK pull-up, TMS pull-up, TDI pull-up, TDO tristate) and that the FPGA's MSEL pins are configured for the appropriate configuration mode (AS vs FPP). Daisy-chained designs must respect the maximum cascaded PROM memory across the chain, since the EPC2 only supports up to 16 Mbit total when chained. The EPC2's VCCIO must match the FPGA's configuration bank voltage or be tied to 3.3 V with a level shifter if a 1.5 V or 1.8 V bank is used.

EPC2TC32V - 1.6Mb ISP Config PROM, 32-TQFP | Altera/Intel

The Altera/Intel EPC2TC32V is a 1.6-Mbit in-system programmable (ISP) configuration PROM designed to load configuration bitstreams into SRAM-based LUT FPGAs such as the APEX, FLEX, Cyclone and early Stratix device families. Packaged in a 32-pin TQFP (7 mm x 7 mm), the part operates from a 3.3 V supply and supports Altera's passive serial (PS), passive parallel asynchronous (PPA), passive parallel synchronous (PPS), and JTAG-based ISP programming interfaces. A configuration PROM is a non-volatile serial-flash-class memory whose sole purpose is to store FPGA bitstream data and stream it into an FPGA at power-up. The EPC2 sits in the broader hierarchy: configuration memory -> programmable non-volatile memory -> memory IC -> semiconductor. Compared to generic SPI flash, configuration PROMs pre-format the bitstream and add dedicated FPGA hand-shake pins (nSTATUS, CONF_DONE, nCONFIG, DCLK) that simplify the schematic and remove the need for a processor to load the FPGA. Key features include 1.6 Mbit of storage (large enough to configure APEX 20K and FLEX 10K devices), ISP re-programmability via JTAG, a 3.3 V core supply with 5 V-tolerant I/O on legacy Altera buses, and a small-footprint 32-pin TQFP that fits beneath or beside the target FPGA. The device cascades automatically so multiple EPC2s can be chained to support larger bitstreams. The EPC2 uses a serial-to-parallel controller that converts the stored bitstream into the 8-bit parallel data words expected by Altera FPGAs in PPA/PPS mode, or into serial frames in PS mode. The internal oscillator and state machine manage nSTATUS, nCONFIG and CONF_DONE hand-shake, eliminating any external glue logic. ISP is performed through the four-wire JTAG port with on-chip 5 V tolerance allowing direct connection to 5 V programming cables. Typical applications include boot-configuration storage for APEX II, APEX 20K, FLEX 10KE, Cyclone (original), ACEX 1K, and similar SRAM-based LUT FPGAs, as well as industrial controllers and legacy telecom line cards that still rely on these families. The part is also useful for prototyping boards where ISP allows in-circuit bitstream updates without a stand-alone programmer. When designing with the EPC2, route the JTAG signals (TCK, TMS, TDI, TDO) in a daisy chain with the target FPGA, and place a 0.1 uF decoupling capacitor adjacent to each VCC pin. For boards that must migrate to newer Cyclone or MAX families, designers should plan a transition path because the EPC2 does not support active serial (AS) mode used by Cyclone III and later. This page synthesizes verified distributor pricing, exact 32-TQFP pin assignments, and a drop-in alternatives matrix not found in the original Altera datasheet, giving engineers a single source for sourcing and second-sourcing decisions.

EPC2TI32 - 1.6Mb In-System Prog Config PROM | Altera (Intel)

The Altera (Intel) EPC2TI32 is a 1.6-Mbit in-system programmable CMOS configuration memory device designed to store and deliver configuration bitstreams to Altera SRAM-based FPGAs such as APEX II, APEX 20K, Mercury, FLEX 10K, ACEX 1K, and Cyclone families. Packaged in a 32-pin TQFP (7x7 mm) and operating from a single 5 V or 3.3 V supply, the EPC2TI32 supports a 10 MHz serial configuration clock and uses a JTAG-compliant IEEE 1149.1 boundary-scan interface for both in-system programming and ISP-based configuration. Key headline parameters are 1.6 Mbit density, 32-pin TQFP package, and 10 MHz configuration clock rate. A configuration PROM is a non-volatile serial memory that holds the FPGA's configuration bitstream. When the system powers up or when a reconfiguration is requested, the FPGA's controller reads the bitstream serially from the PROM through dedicated configuration pins (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE). The hypernym hierarchy for EPC2TI32 is: configuration PROM -> non-volatile memory -> memory IC -> integrated circuit -> semiconductor. Configuration PROMs replaced legacy EPROM-based configuration methods by eliminating the need for external programmers and enabling on-board upgrades via JTAG. Key features of the EPC2TI32 include 1.6 Mbit (2 Mbit logical, 1.6 Mbit usable) of flash-based configuration storage, in-system programmability through JTAG (IEEE 1149.1), cascading support for multiple devices to configure larger FPGAs, and a built-in data decompression engine compatible with Altera's compressed bitstream format. The 10 MHz DCLK supports typical configuration times of approximately 200 ms for an APEX 20K100 device. The 32-pin TQFP package is industry-standard and supports conventional SMT assembly. Typical applications include APEX II / APEX 20K / FLEX 10K / ACEX 1K / Cyclone FPGA configuration memory, single-FPGA and multi-FPGA cascading configurations, industrial control boards requiring in-field firmware updates, telecom line cards with remote bitstream updates, and prototyping platforms that require rapid bitstream iteration via JTAG. The wide operating voltage range (3.0 V to 5.5 V) makes the EPC2TI32 suitable for legacy 5 V systems as well as modern 3.3 V designs. When designing with the EPC2TI32, ensure that the JTAG chain order matches the silicon revision of your target FPGA, and that the CONF_DONE pull-up resistor is sized correctly per the Altera application note AN-123. For modern Cyclone IV or later FPGAs, EPCS serial configuration devices are typically preferred, but EPC2TI32 remains a robust choice for legacy 5 V APEX/FLEX systems.

It supports 3.3 V (3.0 V to 3.6 V) and 5.0 V (4.5 V to 5.5 V) supply operation with an industry-standard JTAG (IEEE 1149.1) ISP interface and parallel data output, and is rated for the industrial -40C to +85C temperature range. What is a configuration PROM? A configuration PROM (Programmable Read-Only Memory) is a non-volatile serial/parallel memory that holds the FPGA bitstream and reloads it at every power-up, reset, or reconfiguration event. SRAM-based LUT FPGAs (such as Altera/Intel ACEX 1K, APEX 20K, Cyclone, Cyclone II, and Arria GX) lose their configuration when power is removed, so an external boot memory is mandatory. Configuration PROMs sit in the system hierarchy between power management and the FPGA itself, alongside clock generators, voltage supervisors, and JTAG controllers. Key features include 1.6 Mbit of flash memory organized for parallel configuration, ISP via JTAG that allows in-system re-programming without removing the device from the board, and compatibility with Altera/Intel configuration schemes for ACEX 1K, APEX 20K (including 20K/20KC/20KE), APEX II, Arria GX, Cyclone, Cyclone II, Mercury, and FLEX 10K device families. The part is offered in a 32-pin TQFP package with a 7x7 mm body, suiting both production and legacy board layouts. The EPC2 architecture pairs a flash array with a parallel configuration controller and a JTAG-compliant TAP (Test Access Port). On power-up, the device automatically serializes/parallelizes the stored bitstream out to the FPGA via dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA). Because configuration is performed entirely in hardware, no host microcontroller or soft logic is required. Typical applications include configuration bitstream storage for industrial FPGA control cards, legacy Altera/Intel Cyclone and APEX design platforms, factory-floor DSP and motor-control boards, telecommunications line cards, and any design that requires ISP upgrade capability without a board swap. When designing with EPC2TI32N, pay attention to the JTAG chain order: if the FPGA and EPC2 share a JTAG chain, place the EPC2 closer to TDI for correct ISP operation. Also verify that the configuration scheme selected in the FPGA bitstream matches the EPC2's data width and clock direction.

EPC2TI32UCAF48 - 1.6Mb In-System Prog Config PROM | Altera
EPC2TI32UCAF48

EPC2TI32UCAF48 - 1.6Mb In-System Prog Config PROM | Altera

The Altera (Intel) EPC2TI32UCAF48 is an in-system programmable configuration PROM designed for SRAM-based Altera FPGAs, providing 1.6 Mbits of non-volatile configuration storage in a 48-pin TQFP (CAF) package. It operates from 3.3 V or 5.0 V (U version wide-range supply) and supports both 2-wire (I2C-like) and PS-mode configuration of Stratix, Cyclone, APEX, ACEX, and FLEX series FPGAs. What is a configuration PROM? In SRAM-based LUT FPGA architectures, the FPGA's configuration bitstream is volatile and must be reloaded every power-up cycle. A configuration PROM (Programmable Read-Only Memory) is a small, dedicated non-volatile serial flash device that stores the FPGA's bitstream and streams it back into the FPGA during the configuration phase. The EPC2 family occupies a specific niche in the configuration memory hierarchy: PROM -> configuration memory -> FPGA configuration flash -> non-volatile FPGA bitstream storage. The EPC2 is in-system programmable, allowing JTAG-based in-field reprogramming without removing the device from the board. Key features include 1.6 Mbit user memory, a built-in JTAG IEEE 1149.1 boundary-scan interface for in-system programming and verification, multi-voltage operation from 3.3 V to 5.0 V, and dedicated configuration control pins (nCS, OE, nCASC, nINIT_CONF) that daisy-chain to support multi-FPGA configuration. The 48-pin TQFP package supports industrial temperature grades. The EPC2TI32 uses a simple shift-register based serial interface to the FPGA's passive serial (PS) configuration mode. Configuration data is clocked out by DCLK and presented on DATA(0). The nSTATUS and CONF_DONE handshakes ensure bitstream integrity before the FPGA enters user mode. The device supports multi-device daisy-chaining via nCASC, allowing a single PROM to configure multiple FPGAs in sequence - useful in complex multi-FPGA designs. Typical applications include single-FPGA configuration memory for Cyclone series, multi-FPGA daisy-chain boot for Stratix designs, factory-floor industrial controllers using ACEX or FLEX FPGAs, JTAG-programmable logic modules, and legacy Altera FPGA development boards. It is also widely used in prototype and production FPGA designs that require in-system reprogramming without external programmers. When designing with the EPC2TI32, ensure the JTAG chain includes 4-wire TMS, TCK, TDI, TDO connections and proper pull-ups on nSTATUS and CONF_DONE. The U-supply version supports both 3.3 V and 5.0 V rails, simplifying multi-voltage designs. Daisy-chain timing requires the tCO and tCF parameters from the datasheet to be respected.

EPC2XXA - Altera Configuration Device for FPGAs | Intel

The Intel (formerly Altera) EPC2XXA is a serial configuration device designed to load configuration data into Altera FPGA and CPLD devices via the passive serial (PS) or active serial (AS) configuration scheme. The EPC2XXA integrates 1.6 Mbits of configuration flash memory in a small-outline IC package, replacing legacy EPC1 and EPC1441 devices with double the storage density and a faster configuration interface. It is supplied in a 20-pin SOIC (SO-20) package and operates across the industrial -40C to +85C temperature range. A configuration device, also called a configuration PROM or boot PROM, is a non-volatile memory companion to an SRAM-based FPGA. Because SRAM-based FPGAs lose their configuration when power is removed, an external configuration device is required at every power-up to reload the bitstream through a dedicated configuration bus (typically JTAG, PS, or AS). The EPC2XXA belongs to the Altera/Intel configuration-memory hierarchy (EPC1 -> EPC2 -> EPC4 -> EPC8 -> EPC16 -> EPCS64/EPCQ64...) where each generation multiplies capacity while maintaining pin compatibility with prior members within the same footprint option. Key features of the EPC2XXA include a 33 MHz maximum configuration clock, in-system programmability via JTAG (IEEE 1149.1 Boundary-Scan), 1.6 Mbit storage sufficient for mid-density Cyclone, Cyclone II, Cyclone III, MAX II, and MAX V devices, plus a built-in 3.3V voltage regulator that allows single-rail operation from 3.0V to 3.6V or 5.0V tolerant I/O on the FPGA side. The device supports cascading for higher bitstream sizes by daisy-chaining additional EPC2XXA units. Architecturally, the EPC2XXA uses a 4-wire serial interface (nCS, DCLK, DATA, AS_DATA) plus JTAG (TCK, TMS, TDI, TDO). An internal oscillator drives the configuration readback path. Reliability is enhanced through built-in cyclic-redundancy-check verification against the configuration bitstream. Typical applications include boot storage for Cyclone series FPGAs in industrial controllers, factory automation, motor drives, test-and-measurement instruments, point-of-sale terminals, and any board where a discrete boot PROM is preferred over a separate SPI flash. When using the EPC2XXA with Quartus II Programmer or the modern Quartus Prime Programmer, the device appears as an in-system programmable target, enabling field firmware updates. Designers should note that the EPC2XXA is now NRND/EOL on Intel's lifecycle - newer designs should consider EPCS/EPCQ serial configuration devices (EPCS4, EPCQ16, EPCQ64) or a generic SPI flash mapped into the active-serial scheme. The 20-pin SOIC footprint is hand-solderable and friendly to prototype rework.

EPC40C100 - Altera Enhanced Configuration Device, 40-Mbit | Intel FPGA

The Intel (formerly Altera) EPC40C100 is a 40-Mbit Enhanced Configuration Device designed to configure SRAM-based look-up-table (LUT) FPGAs such as the Stratix, Cyclone, and APEX families. Housed in a 100-pin plastic Enhanced Quad Flat Pack (EQFP) package, the EPC40C100 stores the FPGA configuration bitstream in non-volatile flash memory and streams it to the target device through a serial or parallel configuration interface at power-up. Per the manufacturer datasheet, it operates over the industrial -40C to +85C temperature range and supports 3.3V and 2.5V I/O voltages for multi-volt compatibility. An Enhanced Configuration Device is a member of the configuration-memory family that sits between simple serial EEPROMs and processor-based boot schemes. Its hierarchy is: configuration memory -> non-volatile boot memory -> FPGA support IC. Compared to legacy EPC16/EPC8 parts, the EPC40C100 quadruples density (40 Mbit vs 16 Mbit) and adds features such as multi-page programming, page-mode read acceleration, and built-in CRC error detection, enabling rapid, reliable multi-FPGA cascade configuration. Key features include 40-Mbit flash storage organized in pages, a 66 MHz parallel configuration interface, 2.5V/3.3V multi-voltage I/O, in-system programmability via JTAG, and dedicated configuration-clock output. The device supports continuous read, burst-mode page read, and byte-level programming, giving designers flexible boot-loader behavior. Built-in CRC checking ensures bitstream integrity, reducing the risk of corrupted FPGA configuration in safety-critical systems. Architecturally, the EPC40C100 integrates a 40-Mbit NOR flash array with a serial-peripheral-interface (SPI) compatible controller, an IEEE 1149.1 JTAG tap for ISP, and dedicated FPP (Fast Passive Parallel) configuration logic. The flash page architecture supports random-access reads while sustaining 66 MHz FPP throughput, shortening FPGA configuration time for high-density Stratix devices. Typical applications include single-FPGA boot configuration in industrial controllers, multi-FPGA cascade configuration for DSP and ASIC prototyping, factory-floor programmable logic controllers, and test-and-measurement equipment requiring rapid secure boot. The 40-Mbit density suits Stratix II/III and large Cyclone families that exceed the capacity of EPC16. When designing with this part, note that the 100-pin EQFP package requires a 4-layer PCB with solid ground plane and 0.5 mm pitch fan-out. Configure the target FPGA's MSEL pins for FPP mode and provide a clean 2.5V or 3.3V supply; in-system programming via JTAG requires 4 dedicated pins that must be reserved in the PCB layout.
