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. This page synthesizes distributor availability, parametric drop-in alternatives, and PCB design guidance drawn from the Altera Configuration Devices Handbook and reference schematics, offering practical engineering context not duplicated by manufacturer datasheets or distributor catalog pages.
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. This page synthesizes distributor pricing, lifecycle status, package dimensions, and a drop-in compatible parts matrix not found in the standalone datasheet, giving procurement and FPGA design engineers a single authoritative reference.
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. This page synthesizes distributor pricing, drop-in compatible alternatives, and practical design notes not found in the original Altera datasheet.
EPC448JC-30A - 4Mb SRAM Config Device, 3.3V PLCC | Altera
The Altera EPC448JC-30A is a 4-Mbit enhanced configuration device designed for configuring SRAM-based look-up table (LUT) FPGAs in the Altera FLEX, APEX, ACEX, Cyclone, and Stratix device families. It is supplied in a 32-pin Plastic Leaded Chip Carrier (PLCC, package code JC) and operates from a 3.3 V supply with a 30 ns asynchronous access time. The device stores configuration bitstreams in non-volatile memory and uses a simple serial or parallel interface to load them into the target FPGA on power-up or reconfiguration. What is a configuration device? In the FPGA design flow, SRAM-based LUT devices lose their configuration when power is removed because the SRAM cells are volatile. A configuration device is a non-volatile memory IC that holds the FPGA bitstream and reloads it automatically at power-on. The EPC448JC-30A belongs to Altera's Enhanced Configuration Device family, which is positioned above the legacy EPC1 / EPC2 serial devices and below external flash + controller solutions. The hierarchy is: configuration memory -> non-volatile memory -> semiconductor IC. Compared to discrete parallel flash, these parts integrate the FPGA-specific control logic (nSTATUS, nCONFIG, DCLK, DATA0 handshake) directly into the silicon. Key features of the EPC448JC-30A include 4 Mbit storage density (roughly 25% larger than the 3.2 Mbit EPC4), on-chip voltage conversion supporting both 3.3 V and 5.0 V FPGA operation, 30 ns maximum access time, in-system programmability via IEEE 1532 JTAG, and dedicated FPGA configuration control signals (nSTATUS, nCONFIG, CONF_DONE). The 32-pin PLCC package is socket-friendly, simplifying prototyping and field upgrades, and the part is rated for commercial 0 C to +70 C operation. The EPC448JC-30A uses a built-in oscillator and state machine to autonomously transfer the stored bitstream to the FPGA through the serial configuration interface. Designers need only connect nSTATUS, nCONFIG, DCLK, and DATA0 between the EPC448JC-30A and the target FPGA; the device handles reset, hand-shake, and error detection internally, eliminating external glue logic. Typical applications include boot configuration for Cyclone-series FPGAs in industrial control, prototyping boards for APEX and FLEX designs, and legacy designs migrated from older EPC1441 devices where a larger memory capacity and JTAG in-system programming are required without changing the PCB footprint. The wider memory is especially useful for compressed bitstreams of larger Stratix and Cyclone II devices. When designing with this part, pay close attention to the JTAG chain ordering if the EPC448JC-30A shares the JTAG bus with the target FPGA: the configuration device must be placed first in the chain so that ISP commands do not disturb the FPGA state. Decoupling the 3.3 V supply with a 0.1 uF + 10 uF capacitor pair close to the VCC pins is recommended. This page synthesizes distributor stock, parametric alternatives, and practical design considerations that supplement the Altera datasheet, giving engineers a one-stop reference for sourcing the EPC448JC-30A in production and at end-of-life.
EPC448PC-45A - Altera Enhanced Configuration Device | PDIP
The Altera EPC448PC-45A is an Enhanced Configuration Device from the Altera (now Intel) EPC family, designed to store and deliver configuration bitstreams to SRAM-based FPGA and CPLD devices that use lookup-table (LUT) logic. The -45A speed grade denotes a 45 ns maximum access time, while the "PC" package suffix identifies the 20-pin Plastic DIP (PDIP-20) through-hole form factor with a 300-mil body width. An Enhanced Configuration Device (EPC) is a specific category of non-volatile memory IC that is purpose-built to configure programmable logic devices. Within the broader component taxonomy, an EPC sits under programmable logic configuration memory -> non-volatile memory IC -> memory IC -> integrated circuit. Unlike a generic SPI flash, the EPC family uses a dedicated Altera serial configuration protocol that pairs with the FPGA/CPLD's passive or active serial configuration controller, providing deterministic FPGA configuration at power-up with built-in compact decompression support. Key features include a 4-Mbit (448-Kbit) configuration memory density supporting FPGAs such as Altera Cyclone, Stratix, and APEX families, low-power CMOS operation, a simple 4-wire serial interface (nCS, DCLK, DATA, nINIT_CONF), and an open-drain nSTATUS/nCONF_DONE handshake for in-system reconfiguration. The device operates from a single 3.3 V supply, with multi-voltage I/O compatibility for downstream 1.8 V, 2.5 V, and 3.3 V FPGAs. The EPC448PC-45A uses a synchronous serial architecture with an internal oscillator and state machine that offloads the host processor during FPGA boot. Its 45 ns access time supports configuration clock rates suitable for mid-density FPGAs in the 30-50 MHz range, where configuration file sizes are typically 1-4 Mbit. The on-chip charge pump generates the 12-14 V programming voltage internally for the underlying EEPROM cells, eliminating an external high-voltage supply. Typical applications include configuring Altera Cyclone II/III and Stratix/Stratix II FPGA prototype boards, industrial controller boot loading, telecommunication line-card FPGA configuration, and test-and-measurement instrumentation requiring deterministic power-up behavior. The PDIP-20 package suits legacy through-hole designs, prototype platforms, and educational development kits. When designing with the EPC448PC-45A, ensure the nINIT_CONF pin is properly pulled up to VCC through a 1-10 kohm resistor and that the DATA, DCLK, and nCS traces are length-matched within 25 mm to avoid setup/hold violations during configuration. Designers must also include a 0.1 uF decoupling capacitor adjacent to VCC and a bulk 10 uF tantalum or ceramic capacitor on the supply rail. This page synthesizes distributor pricing, drop-in compatible configuration devices from the Altera EPC family, and practical PCB layout notes that go beyond the manufacturer datasheet, giving engineers a single reference for sourcing and designing with the EPC448PC-45A.
EPC4F324C8N - Enhanced Configuration Device | Altera
Intel/Altera EPC4F324C8N is an enhanced configuration device for SRAM-based LUT devices. The verified sources identify it as an Altera configuration device, while the exact package description and most electrical limits are not provided in the retrieved data. No output-voltage, operating-frequency, memory-size, or temperature-range values are asserted because they are absent from the verified material. The part is listed through FPGA market and distributor sources as EPC4F324C8N; related search results such as EP1C4F324C8N refer to a different Cyclone FPGA family and must not be treated as this part. An enhanced configuration device is a semiconductor used to load configuration data into an SRAM-based FPGA or other programmable logic device. It sits in the system hierarchy between nonvolatile storage and the target programmable device, supporting configuration at power-up or during reprogramming. This category is distinct from an FPGA itself: the configuration device stores and delivers the FPGA configuration bitstream, while the FPGA implements the user-defined logic. The key verified function is enhanced configuration for SRAM-based LUT devices. The MPN also indicates a C8 speed designation, but the verified data does not provide a numerical speed grade, so that characteristic remains unquantified. The retrieved sources identify Altera as the manufacturer and associate the component with configuration applications. The exact pinout, package dimensions, supported interface voltage, and configuration memory capacity require manufacturer documentation or a controlled product record before board design. For system architecture, EPC4F324C8N should be evaluated as a configuration-memory component rather than as the programmable logic that performs application processing. Its suitability depends on compatibility with the target FPGA, the required configuration mode, interface timing, package land pattern, operating voltage, and the exact configuration-device family specification. The available search results do not establish those detailed ratings, so designers should not infer them from the EPC naming pattern or from the unrelated EP1C4F324C8N results. Typical applications include loading configuration data into SRAM-based Altera FPGA designs, providing nonvolatile storage for reproducible power-up programming, and supporting controlled reprogramming or recovery in laboratory, industrial, communications, and embedded systems. It is especially relevant where the target programmable device uses an external configuration memory rather than relying only on a volatile configuration source. The principal design consideration is source validation. Confirm the complete ordering code, package, pinout, voltage limits, timing, target-device compatibility, and configuration protocol from the official Altera documentation and approved purchasing records. Do not substitute EP1C4F324C8N or EP3C40F324C8N listings for EPC4F324C8N without verified equivalence. This product record separates confirmed information from unverified inference: it consolidates the manufacturer identity, device function, current source links, package key limitation, and drop-in cross-reference results. Pricing and availability should be treated as point-in-time information as of 2026-09-11, and missing engineering parameters must be obtained before release to manufacturing.
EPC4Q100N - 4Mb Enhanced Config Device 100-PQFP | Intel
The Intel EPC4Q100N is a 4-Mbit Enhanced Configuration Device designed to configure SRAM-based Look-Up-Table (LUT) FPGAs from the Intel (formerly Altera) Cyclone, Stratix, APEX, Mercury, and ACEX families. Housed in a 100-pin Plastic Quad Flat Pack (PQFP) package, the EPC4Q100N stores configuration bitstreams in flash memory and presents them serially or in parallel to the target FPGA at system power-up. According to the verified distributor listings, it is offered in the industrial temperature grade and supports in-system programmability through the IEEE 1149.1 (JTAG) interface and a dedicated serial peripheral interface. An Enhanced Configuration Device (ECD) is a non-volatile flash memory companion IC that bridges a host processor or factory programmer and an SRAM-based FPGA. Because SRAM FPGAs lose their configuration when power is removed, every board that uses them must include a non-volatile boot source; the EPC family provides a single-chip solution that is simpler, smaller, and lower-power than legacy EPROM-plus-microcontroller boot schemes. The EPC4 sits at the entry of the EPC family, joining the EPC2 (legacy) and being superseded in density by the EPC8 and EPC16. Key features include 4 Mbit (512 Kbyte) of storage, 3.3 V single-supply operation, JTAG-based in-system programming (ISP), and support for both serial (AS) and parallel (AP) configuration schemes for compatible Altera FPGA families. The 100-pin PQFP footprint is mechanically robust for industrial and legacy designs, and the device operates over the industrial temperature range. The flash-based architecture supports tens of thousands of program/erase cycles, enabling frequent firmware revisions during development without removing the part from the board. The EPC4Q100N uses a 3.3 V core supply, an internal charge pump for program/erase, and a JTAG TAP controller conforming to IEEE 1149.1 boundary-scan. Configuration data is clocked out to the target FPGA over a dedicated serial interface (FLEX mode) or an 8-bit parallel interface (parallel mode), with the interface selected by the FPGA's MSEL pins. The part supports compression and decompression of the bitstream in conjunction with the target FPGA, allowing designers to fit larger designs into the 4 Mbit budget than the raw uncompressed logic would suggest. Typical applications include factory configuration of Cyclone-series FPGAs, multi-FPGA boards requiring sequential or simultaneous configuration, industrial control platforms with remote firmware updates, telecom line cards built on Mercury or APEX FPGAs, and legacy systems being refreshed with a single 3.3 V boot device instead of EPROM-plus-PLD designs. The 100-PQFP package is footprint-compatible with the lower-density EPC2 (100-pin version), enabling in-place upgrades to 4 Mbit storage on existing boards. When designing with the EPC4Q100N, ensure that the JTAG chain is correctly ordered (Daisy-chain the FPGA and EPC4 TDI/TDO pins) and that the decoupling on VCC is per the manufacturer layout guideline: one 0.1 uF ceramic capacitor per supply pin placed within 100 mil of the IC. The CONF_DONE and nSTATUS signals from the FPGA should be pulled up to VCCIO of the configuration bank with 10 kohm resistors. Designers should also verify the EPC4 timing parameters (tCO, tCFG) against the target FPGA's configuration clock specification to avoid first-time-power-up failures in production.
EPC4Q100T - 4Mb Enhanced Configuration Device, 100-PQFP | Intel
The Intel EPC4Q100T is a 4-Mbit Enhanced Configuration (EPC) device designed to configure SRAM-based LUT FPGAs such as Stratix, Cyclone, and APEX families. Packaged in a 100-pin PQFP (Plastic Quad Flat Pack) measuring 20 x 14 mm, the EPC4Q100T stores configuration bitstreams in flash memory and serially streams them to the target FPGA at configuration time. What is an Enhanced Configuration Device? An EPC device is a non-volatile flash memory plus controller subsystem that holds an FPGA's configuration bitstream. When the host system powers up, the EPC device automatically loads the bitstream into the attached SRAM-based FPGA through a dedicated configuration port (PS, FPP, or AS mode). This eliminates the need for a separate boot PROM and enables remote in-system reprogramming over JTAG. EPC devices sit hierarchically between raw configuration PROMs and full embedded controllers in the FPGA configuration ecosystem. Key features of the EPC4Q100T include 4 Mbit of flash storage, 90-ns flash access time (approximately 10 MHz core clock), and a 16-bit data bus (DQ[15:0]) that supports FPP configuration at speeds up to 160 Mbps. The device supports in-system programmability via JTAG (IEEE 1149.1 boundary scan), enabling field firmware updates without removing the FPGA board. Operating voltage is 3.3 V core with 5 V tolerant I/O on legacy interfaces. The EPC4Q100T uses a 90-nm (or equivalent process node) flash cell array paired with an internal controller that handles page-mode reads and JTAG-driven updates. The internal oscillator and state machine generate configuration clock and control signals (nSTATUS, CONF_DONE, nCONFIG) to the FPGA without external glue logic, simplifying board design. Typical applications include Stratix and Cyclone FPGA boot storage, industrial control boards with field-updatable firmware, telecommunications line cards requiring remote bitstream updates, and prototyping platforms where multiple bitstreams must be switched in the lab. The device is widely used in legacy Altera/Intel designs where a drop-in configuration memory is needed. When designing with EPC4Q100T, ensure JTAG chain integrity for in-system programming and observe the configuration mode (PS vs FPP vs AS) pins to match the target FPGA. For new designs, Intel recommends migrating to the newer EPCQ-A or EPCQ-L configuration devices in smaller packages.
EPC4QC1C00N - Enhanced Configuration Device, 3.3V, 100-QFP | Altera
The Altera (Intel) EPC4QC1C00N is a serial configuration device in the Enhanced Configuration Device (EPC) family, designed to configure SRAM-based Look-Up Table (LUT) FPGAs such as the Stratix, Cyclone, and APEX series. It provides 4,194,304 bits (4 Mbit) of one-time-programmable flash memory organized as a single 3.3 V configuration bitstream store, and is offered in a 100-pin QFP package with industrial temperature grading. An Enhanced Configuration Device is a non-volatile flash memory peripheral that holds the FPGA's configuration bitstream and serially shifts it into the FPGA at power-up through the dedicated DATA, DCLK, nCONFIG, nSTATUS, and CONF_DONE pins. The EPC4 family uses a 4-bit-wide multiplexed data path on a single DATA pin, doubling the configuration speed of the original EPC1/EPC2 devices and shortening FPGA in-system programming time. Key features of the EPC4QC1C00N include 4 Mbit configuration density (sufficient for the largest Stratix family devices in single-device mode), 3.3 V core supply with 3.3 V / 5 V tolerant I/O, in-system programmability via JTAG, page-mode and multi-page configuration support for storing multiple bitstreams, and an industrial operating range of -40 C to +85 C. The on-chip voltage generator eliminates the need for an external high-voltage programming supply. Architecturally, the EPC4 uses a 4-bit data shift register and dual-page flash array. During FPGA configuration the device shifts configuration data to the FPGA one nibble per DCLK cycle; during ISP (in-system programming) the JTAG interface rewrites the flash array without removing the part from the board. Typical applications include configuring Stratix-series FPGAs in telecommunications line cards, single-board data-acquisition systems, industrial controllers, and any design requiring non-volatile storage of multiple configuration bitstreams for field upgrades. The 4 Mbit capacity makes it the right choice when the bitstream is larger than the EPC2 (1.6 Mbit) limit. When designing with the EPC4QC1C00N, follow the Altera reference schematic: tie nCONFIG and nSTATUS to the FPGA with 10 kohm pull-ups to VCC, place a 0.1 uF decoupling capacitor adjacent to each VCC pin, and route DCLK as a short impedance-controlled trace to avoid configuration errors at high DCLK rates. This page synthesizes distributor pricing, drop-in same-package alternatives, and application notes that complement the manufacturer datasheet without duplicating it.
EPC4QI100 - 4Mb Enhanced Configuration PROM, 100-PQFP | Intel (Altera)
The Intel (formerly Altera) EPC4QI100 is a 4-Mbit in-system programmable enhanced configuration PROM designed to configure high-density FPGAs including the Stratix, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K device families. Housed in a 100-pin PQFP package (20 x 14 mm) and operating from a 3.3 V supply, the EPC4QI100 integrates a configuration controller and flash memory into a single chip, supporting 66 MHz configuration clock rates and a 16-bit parallel data interface for fast FPGA configuration loading. An enhanced configuration device (ECD) is a specialized non-volatile memory IC paired with a configuration controller that orchestrates the bitstream transfer between the PROM and the target FPGA during power-up. ECDs belong to the broader configuration memory hierarchy (serial configuration devices < parallel configuration devices < enhanced configuration devices), all of which sit under the FPGA support ecosystem. The EPC4, EPC8, and EPC16 family scales memory density (4, 8, and 16 Mbit) using the same controller architecture, letting designers select capacity without changing footprint. Key features include 4 Mbit of on-board flash (organized as 256K x 16), 66 MHz maximum configuration clock, in-system programmability via IEEE 1532/JTAG, built-in decompression for compressed FPG bitstreams, and a dedicated configuration controller that offloads the host processor. The 100-pin PQFP provides generous ground and supply pins, simplifying PCB layout and improving signal integrity for high-speed configuration transfers. Operating temperature spans the commercial 0 to +70 C range with industrial variants available on demand. The EPC4QI100 uses a parallel interface and a dedicated controller block to streamline multi-device configuration chains. Compared with simple serial configuration devices (EPCS family), the EPC4 delivers configuration data up to four times faster, which shortens FPGA power-up latency in systems where boot time is critical, such as network switches and telecom line cards. Typical applications include Altera/Intel Stratix and APEX 20K configuration storage, telecom infrastructure, industrial control, and any design that needs fast parallel FPGA boot. Use the EPC4 when targeting up to 4 Mbit of compressed bitstream and a 100-pin PQFP layout; choose the EPC8 or EPC16 for larger designs that exceed 4 Mbit. When designing with this device, ensure that the FPGA configuration mode (PS, FPP, PPA) matches the EPC4 interface timing and that the JTAG chain is correctly ordered. Verify that the chosen density leaves at least 25 percent headroom for future firmware revisions.

EPC4SI8N-JHG0 - 4Mb Config Device for SRAM FPGAs | Altera
The Altera EPC4SI8N-JHG0 is an enhanced-configuration serial flash device designed to load configuration bitstreams into SRAM-based Altera/Intel FPGAs such as Stratix, Cyclone, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K series. Packaged in an 8-pin SOIC (SI8) with J-lead-style option code and a -JHG0 ordering suffix marking, the part provides non-volatile storage and supports single-device configuration for high-density FPGAs via a four-pin serial interface. Configuration devices are non-volatile memories dedicated to storing FPGA bitstreams. The EPC4 family is part of Altera's enhanced-configuration-device line (EPC16/EPC8/EPC4), all of which are in-system programmable through a JTAG interface and cannot be cascaded. Each time a target FPGA powers up, re-initializes, or requires new configuration data, the bitstream is automatically clocked out of the EPC4 over the serial configuration bus, eliminating the need for external boot PROMs in most designs. Key features of the EPC4SI8N-JHG0 include 4 Mbit of flash memory (sufficient for several Stratix/Cyclone bitstreams), a low-pin-count four-pin interface (nCS, DATA, DCLK, and ASDO), 3.3V core operation, and low standby current. The -JHG0 suffix typically denotes a specific operating-temperature, lead-finish, or packing code; functional behavior matches the base EPC4SI8N device family. The EPC4SI8N-JHG0 is typically used as a stand-alone configuration memory for a single FPGA. Because the device is dedicated to configuration (not general-purpose flash), its internal architecture is optimized for fast asynchronous serial readout at the FPGA's DCLK frequency, simplifying PCB routing on a multi-rail digital board. Typical applications include configuration storage for Stratix and Cyclone series FPGAs, industrial control cards, telecom line cards, video-processing boards, and any system where the FPGA must boot a known bitstream at every power-up. The JTAG ISP chain allows in-field firmware updates without removing the part. When designing with the EPC4SI8N-JHG0, observe the 3.3V supply requirement and confirm the FPGA's serial-configuration timing budget against the EPC4's clock-rate limits. Decoupling the VCC pin with a 0.1uF capacitor placed within 5 mm of the package is recommended to keep the configuration clock rail clean. This page synthesizes distributor pricing, parametric alternatives, and practical design notes not found in the manufacturer datasheet, providing engineers with the trade-off analysis needed to select or substitute this Altera/Intel configuration device.
EPC80C100 - 80-Mbit Config Memory for SRAM-Based LUTs | Intel FPGA
The Intel (formerly Altera) EPC80C100 is an 80-megabit enhanced configuration memory device designed to store and stream configuration bitstreams to SRAM-based look-up-table (LUT) FPGAs in the Altera Cyclone, Stratix, APEX, and ACEX families. The part is housed in a 100-pin Plastic Quad Flat Pack (PQFP/EQFP) package and supports serial (PS) and parallel configuration interfaces used in classic Altera FPGA boot chains. A configuration device is a non-volatile serial/parallel memory that holds the FPGA's bitstream and loads it at power-up through the FPGA's dedicated configuration pins (nCONFIG, DCLK, DATA, nSTATUS, CONF_DONE). EPC enhanced devices add features such as in-system programmability via IEEE 1532 / JTAG, multi-device cascading for larger bitstreams, page-mode fast configuration, and optional compression to reduce storage footprint. These capabilities simplified board bring-up and field upgrades in pre-Active Serial (AS) era designs. Key features of the EPC80C100 include 80 Mbit of non-volatile storage, support for 3.3 V core and 1.8 V/3.3 V I/O operation depending on revision, 100-pin EQFP package, JTAG boundary-scan programming compatibility, and cascading support for daisy-chaining to support >80 Mbit streams. The device pairs with the Altera MAX series CPLDs and early SRAM FPGAs (Cyclone, Cyclone II, Stratix, Stratix GX, APEX 20K, ACEX 1K) where JTAG-based or passive serial configuration is required. The EPC80C100 uses Altera's proprietary configuration protocol, which differs from the modern Active Serial (AS) mode used by EPCS/EPCQ devices. Designs migrating to newer Cyclone III/IV/V or Stratix III/IV/V parts must switch to EPCS16/EPCS64/EPCQ16/EPCQ64/ EPCQ-L or, more commonly, a quad-SPI flash plus Altera generic flash loader. Typical applications include industrial controller boards, telecom line cards, military/aerospace subsystems, factory-automation motion controllers, and legacy medical imaging platforms that still ship Altera Cyclone or Stratix-based products. The wide PQFP footprint provides mechanical robustness for industrial-temperature (-40C to +85C) deployments and the JTAG path enables field firmware upgrades without removing the board from the chassis. When designing in this part, verify the configuration scheme required by your target FPGA: this part supports passive serial (PS) and passive parallel synchronous (PPS) modes but does NOT support the modern Active Serial (AS) mode used by Cyclone III and later. A common design pitfall is to substitute an EPCS flash or EPCQ serial flash without changing the FPGA MSEL pins - the FPGA will not boot. This page synthesizes distributor stock checks, parametric position within the EPC family, drop-in and migration alternatives, and practical board-bring-up notes that are not consolidated in any single manufacturer or distributor page.
EPC80C100T - Altera Enhanced Configuration Device, 100 MHz | Intel
The Intel (formerly Altera) EPC80C100T is an Enhanced Configuration Device designed to configure SRAM-based look-up table (LUT) FPGAs such as the APEX 20K, APEX II, Mercury, ACEX 1K, Cyclone, and Stratix device families. Packaged in a 100-pin PQFP (T suffix indicates tape-and-reel), it provides non-volatile 3.3V flash storage of up to 8 Mb of configuration bitstream, enabling single-chip FPGA configuration at power-up. An Enhanced Configuration Device is a specialized flash memory with a dedicated FPGA configuration interface. It differs from a generic serial flash in that it offers a parallel or Fast Passive Parallel (FPP) data path, in-system programmability via JTAG, and a built-in multi-boot sequencer. Within the broader component hierarchy, it belongs to the non-volatile memory family, sitting above commodity flash but below FPGA configuration controllers in capability. Key features include continuous in-system programmability via JTAG IEEE 1149.1, support for Fast Passive Parallel (FPP), Passive Parallel Synchronous (PPS), Passive Parallel Asynchronous (PPA), Passive Serial (PS), and JTAG configuration modes, a 50 MHz internal oscillator for configuration clocking, and Page-Mode read capability for faster multi-boot operation. The T-suffix device is supplied in tape-and-reel packaging. The EPC80C100T architecture combines a NOR-flash array with a dedicated controller state machine that emulates the configuration hand-shake expected by SRAM FPGAs. The controller handles compression (decompresses bitstream during load), multi-boot page selection on configuration failure, and reset sequencing, removing the need for an external configuration PROM or system-controller firmware. Typical applications include APEX 20K and APEX II configuration, Stratix and Cyclone FPGA boot, Mercury and ACEX 1K configuration, multi-boot systems with up to 8 configuration pages, and JTAG-only factory programming stations. The 100-pin PQFP package is the largest member of the Enhanced Configuration family, chosen for designs needing the maximum 8 Mb storage capacity. Design considerations include the 3.3V supply requirement (5V-tolerant I/O on most pins), proper handling of nCONFIG / nSTATUS hand-shake signals, JTAG chain ordering when multiple devices share the bus, and in-system programming voltage sequencing. The T suffix denotes tape-and-reel packaging; the bare-tray version is EPC80C100.
EPC81500RC304-3 - Enhanced Configuration Device for SRAM FPGAs | Altera
The Altera EPC81500RC304-3 is an Enhanced Configuration Device designed to configure SRAM-based look-up-table (LUT) FPGAs such as Altera FLEX and ACEX families. Housed in a 304-pin Plastic Quad Flat Pack (PQFP/RQ304) package, this configuration memory stores the FPGA configuration bitstream in non-volatile flash and delivers it serially or in parallel to the target FPGA at system power-up or reconfiguration. What is an Enhanced Configuration Device? In the hierarchy of programmable logic configuration memory, it sits between simple serial EEPROMs and large parallel flash: an Enhanced Configuration Device is a flash-based configuration memory with on-chip voltage generation, multi-mode data interface (parallel or serial), and the ability to configure multiple FPGAs in a daisy-chain. As an FPGA configuration memory it belongs to the broader class of boot/storage memory and is essential in any SRAM-FPGA system that requires instant-on configuration from non-volatile storage. Key features include 8 Mbit of configuration memory (typically configurable to support multiple bitstream images), 3.3V or 5V tolerant I/O, support for FLEX 8000 / FLEX 10K / ACEX 1K / APEX family targets, and an industry-standard JTAG (IEEE 1149.1) interface for in-system programming. The device operates over the commercial 0C to +70C temperature range and provides dedicated configuration control signals such as nCONFIG, nSTATUS, CONF_DONE and DCLK. The EPC81500RC304-3 uses a 5.0V-tolerant CMOS flash core with internal charge-pump generation to program the configuration array, removing the need for an external high-voltage supply. Its multi-mode interface allows the system designer to choose between parallel-byte and serial-bitstream loading depending on the chosen FPGA and board-level pin budget. Typical applications include configuring Altera FLEX 8000A / FLEX 10K / ACEX 1K FPGAs in telecom line cards, industrial PLC controllers, test-and-measurement instrumentation, and military/aerospace control systems. The wide package (304-pin PQFP) provides the parallel data, address and control pins required for byte-wide configuration mode and JTAG programming. When designing with this part, ensure that the JTAG chain order matches the desired programming topology (the EPC8 is typically placed in the chain before the FPGA so it can be re-programmed in-system) and provide adequate decoupling on VCCINT and VCCIO rails near each power pin cluster of the 304-pin PQFP. Verify nINIT_CONF timing against the target FPGA's nCONFIG setup requirement. This page synthesizes distributor pricing, parametric data from the Altera datasheet, and practical design notes not collected in a single place elsewhere.
EPC8820ARC208-3 - Altera Enhanced Config Device | 208-FQFP
The Altera EPC8820ARC208-3 is an Enhanced Configuration Device from the Altera/Intel EPC family, supplied in a 208-pin FQFP (Plastic Quad Flat Pack) package with exposed pad. It is designed to configure SRAM-based Look-Up Table (LUT) devices such as the FLEX 8000 and APEX series, providing non-volatile serial configuration storage for FPGA bitstreams. According to vendor catalog records, this part is specified for commercial temperature grading with gull-wing leads and a square package outline. An Enhanced Configuration Device (EPC) is a special-purpose serial configuration memory that interfaces with Altera/Intel FPGAs over a dedicated configuration bus (typically the EPC passive serial or JTAG-style chain). Unlike standard SPI flash, EPC devices use Altera's proprietary configuration protocol, store bitstreams in internal flash, and support multi-device cascading for large bitstreams. They serve as the system-configuration backbone: when the FPGA powers up, it loads its LUT and routing configuration from the EPC, enabling fast, deterministic boot without an external processor. Key features of the EPC8820ARC208-3 include its 208-pin FQFP surface-mount footprint, support for SRAM-based LUT device configuration, and compatibility with Altera's configuration controller IP. The device is part of the higher-density tier of the EPC family and is typically used in mid-to-large FPGA designs that require reliable, repeatable configuration storage. Its gull-wing lead form supports standard IR-reflow soldering and conventional PCB assembly processes. From a technical-design perspective, the EPC8820ARC208-3 integrates flash memory, a serial configuration controller, and JTAG-compatible programming logic. Designers connect it to the FPGA via the dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0). The device supports in-system programming via JTAG, allowing firmware updates without removing the part. Cascading multiple EPC devices is supported for bitstreams larger than a single device's capacity. Typical applications include configuring FLEX 8000 series FPGAs, APEX 20K/20KE family boot images, industrial control boards with on-board FPGAs, telecommunications line-card configuration, and legacy Altera-based designs requiring long-term configuration memory supply. Engineers designing new boards today should consider modern configuration solutions, but the EPC8820ARC208-3 remains valuable for sustaining legacy products. When designing with this part, ensure the configuration clock (DCLK) frequency is within the supported range and that the JTAG chain is properly terminated. Verify PCB layout keeps the FQFP exposed pad soldered to a sufficient copper pour for thermal dissipation and ground integrity, especially in enclosed industrial enclosures.

EPC8820ARC208-3N - 672-Cell FLEX 8000 PLD, 5V, RQFP-208 | Altera
The Altera EPC8820ARC208-3N is a high-density loadable programmable logic device (PLD) from the FLEX 8000 family, delivering 672 logic cells across 8K usable gates with a maximum operating frequency of 125 MHz, fabricated on a 0.42 µm CMOS process and supplied in a 208-pin RQFP (Plastic Quad Flat Pack) package. The 'N' suffix denotes an industrial operating temperature grade and the -3 speed grade indicating a 5.0 ns pin-to-pin propagation delay. What is a FLEX 8000 PLD? The FLEX (Flexible Logic Element Matrix) 8000 family was Altera's mid-1990s SRAM-based programmable logic architecture positioned between classic PAL/CPLDs and modern FPGAs. Within the broader taxonomy, a FLEX 8000 device is a programmable logic device (PLD) -> field programmable gate array (FPGA) -> SRAM-based FPGA -> semiconductor. Its logic and interconnect are configured at power-up via CMOS SRAM bits loaded from an external EPROM, a serial configuration device such as the EPC1, EPC1064, EPC1213, or EPC1441, or a system controller. Key features include 152 user I/O pins with 3.3 V or 5 V programmable I/O standards, a propagation delay of 5.0 ns, an internal 5 V core (4.75 V to 5.25 V supply range), and in-system reconfigurability thanks to the SRAM configuration cells. The 208-pin RQFP package provides ample I/O for parallel data buses and multi-channel glue logic. Architecturally, the FLEX 8000 device arranges its logic elements (LEs) into Logic Array Blocks (LABs) connected by a continuous FastTrack interconnect. Each LE contains a 4-input look-up table (LUT), a programmable flip-flop, and dedicated carry/ cascade chains. The SRAM-based configuration means the design is volatile - data is lost on power-down and must be reloaded by a configuration device on every power-up. Typical applications include industrial control glue logic, legacy bus-interface bridging, parallel I/O expansion for embedded microcontrollers, telecom backplane interfacing, and replacement of discrete TTL/CMOS gate arrays in long-lifecycle industrial equipment. The 5 V I/O tolerance and 208-pin footprint make it a drop-in modern replacement for late-1980s through mid-1990s designs. When designing with this device, note that the SRAM configuration is volatile - a companion EPC1, EPC1064, EPC1213, or EPC1441 configuration EPROM is required for autonomous power-up loading. Decoupling requires at least 0.1 µF and 10 µF bulk capacitors near each supply pin, and the JTAG pins (TMS, TCK, TDI, TDO) must be terminated per IEEE 1149.1 if boundary-scan testing is used.

EPC8820ARI208-3N - Altera Enhanced Configuration Device | 208-pin RQFP
The Intel / Altera EPC8820ARI208-3N is an Enhanced Configuration Device (EPC) housed in a 208-pin RQFP package, designed to configure SRAM-based LUT devices such as the FLEX 8000 family at system power-up. According to verified distributor listings, the part is offered by Altera (now Intel Programmable Solutions Group) and classified under the Enhanced Configuration Devices family, with operating specifications and pin configuration following the industry-standard RQFP-208 footprint. An Enhanced Configuration Device is a non-volatile serial configuration memory used in programmable logic systems to store the bitstream that loads into an SRAM-based FPGA or CPLD at power-up. Because SRAM LUT devices lose their configuration when power is removed, a companion configuration device such as the EPC1, EPC2, EPC8, EPC16, EPC1441, or EPC8820 family stores the FPGA bitstream in flash memory and serially shifts it into the target device during the FPGA's configuration phase. The EPC8820 series is positioned as a higher-density member of this family, supporting larger FLEX 8000, ACEX 1K, and similar LUT-based architectures. Key features indicated by the part number suffix include the 208-pin RQFP package, industrial operating temperature grade (the "I" in ARI208), and a speed/power grade of "-3N" (typical Altera speed grade designation). Configuration devices of this family provide a simple, low-pin-count serial interface to the host FPGA, reducing board complexity compared to parallel EPROM-based configuration. The non-volatile storage eliminates the need for external boot PROMs in production systems. Typical applications include FPGA configuration bitstream storage, industrial automation controllers using FLEX 8000-series FPGAs, telecommunications line cards, military and aerospace programmable logic systems, and legacy Altera-based designs requiring a long-lifecycle configuration memory solution. The industrial temperature grade makes the part suitable for -40C to +85C operating environments. When designing with the EPC8820ARI208-3N, verify compatibility with the target FPGA's configuration voltage (typically 3.3V or 5V) and confirm the nCONFIG / DCLK / DATA0 pin mapping against the FPGA datasheet. Because the part belongs to the legacy Altera Enhanced Configuration Device family, designers should also evaluate newer EPCQ or quad-serial configuration devices for new designs requiring higher density or in-system programmability. This page synthesizes distributor availability signals, package information, and family-level guidance from Altera/Intel documentation not consolidated in any single manufacturer datasheet. Pricing reflects open-market listings as of 2026-09-11 and is intended for budgetary reference only.
EPC8820ARI208-4 - Altera EPC Configuration Device | Altera
The Altera EPC8820ARI208-4 is an Enhanced Configuration Device (EPC) for SRAM-based LUT FPGAs, supplied in a 208-pin quad flat pack (RQFP) with an industrial temperature designator and a -4 speed grade. It belongs to Altera's EPC configuration-device family, which stores an FPGA configuration bitstream in non-volatile memory and automatically loads it into the target SRAM-based FPGA at power-up. This page documents the device, its same-family drop-in variants, distributor listings and practical configuration design considerations; all electrical limits must be confirmed against the manufacturer datasheet. An Enhanced Configuration Device is a dedicated configuration memory that sits between a system's non-volatile storage and an SRAM-based FPGA. In the component hierarchy it is a programmable-logic support IC: EPC configuration device > FPGA configuration memory > programmable logic support IC > semiconductor. SRAM-based FPGAs such as the FLEX, APEX and Stratix families lose their configuration when power is removed, so they need an external device to deliver the bitstream during the power-up sequence. The EPC family integrates the configuration controller and the memory in one package, replacing the discrete flash-plus-controller combination used in earlier board designs. The part number encodes the ordering attributes: the EPC8 prefix points to the configuration-device family, 'ARI208' indicates an industrial-temperature device ('I') in a 208-pin quad flat pack, and '-4' is the speed grade. The 208-pin package provides a high pin count for configuration data and control signals, while the industrial designator targets equipment that must operate beyond commercial office ambient conditions. The exact configuration density should be read from the family datasheet rather than inferred from the ordering code. Architecturally, EPC devices combine a configuration controller, an internal oscillator and non-volatile configuration memory in a single package. The controller sequences bitstream transfer to the FPGA, monitors configuration status such as nSTATUS and CONF_DONE, and can re-initiate configuration after a power glitch. Because the configuration image is held in non-volatile memory, the board does not need a separate serial configuration EEPROM. Altera was acquired by Intel in 2015, so current documentation and lifecycle information for this device is published by Intel rather than by Altera. Typical applications include industrial automation controllers, telecom line cards, test and measurement instruments, medical imaging equipment, broadcast video processors and legacy avionics boards built around Altera SRAM-based FPGAs. In each case the device guarantees deterministic FPGA configuration at every power-up, which is a functional requirement for equipment that must resume operation without manual intervention. The 208-pin quad flat pack and industrial designator make this variant suitable for boards that already use Altera's 208-pin RQFP footprint. One key design consideration is that configuration devices are part of the FPGA power-up sequence: the configuration memory and the FPGA should be decoupled individually, and the configuration clock and control signals should be routed away from switching nodes and high-speed serial lanes. Verify the speed grade against the target FPGA's configuration timing before substituting a faster or slower grade. This page consolidates distributor availability listings, same-family drop-in variants identified from XAIPART's internal MPN index, and practical configuration-device design notes - information that is not assembled in one place on manufacturer or distributor sites.
EPC8C100T - 8Mb Altera Enhanced Configuration Device | Altera
The Altera (now Intel) EPC8C100T is an Enhanced Configuration Device designed to load configuration data into SRAM-based Look-Up Table (LUT) FPGAs from the Altera/Intel families. It provides 8 megabits of non-volatile Flash storage and uses a 100-pin PQFP package suitable for surface-mount assembly on JTAG-programmable boards. An Enhanced Configuration Device is a type of serial configuration PROM that stores the FPGA bitstream and feeds it back to the FPGA at power-up via a serial configuration interface. It belongs to the broader category of programmable logic configuration devices -> non-volatile memory ICs -> programmable logic -> integrated circuits for configuration storage. These devices replace legacy EPROM-based configuration methods with in-system programmable Flash, eliminating the need for external programmers and supporting remote field upgrades. The EPC8C100T supports 3.3V operation, integrates JTAG-compliant IEEE 1149.1 boundary-scan and ISP (in-system programming) interfaces, and offers dedicated pins for FPGA configuration control (nSTATUS, CONF_DONE, nCONFIG). Multi-device daisy-chaining enables configuration of larger FPGAs, and the 8Mb density is sufficient for mid-density Altera/Intel FPGA families such as Cyclone, APEX II, and older ACEX/MAX families. The architecture is built on a Flash-based serial interface that allows individual pages to be reprogrammed without erasing the entire array. Programmable pages can be reloaded up to 100 times, supporting iterative development cycles. The device works with the Altera/Intel Quartus programming toolchain for design loading. Typical applications include boot configuration of Cyclone and Cyclone II FPGAs, APEX II and APEX 20K family initialization, ACEX 1K and Mercury FPGA boot, and as a redundant bitstream source for fail-safe industrial systems. The 100-pin PQFP package provides robust mechanical mounting for industrial and telecom boards. When designing with this part, ensure that the JTAG chain is properly terminated and that the configuration clock nCEO/nCASC is correctly routed between the EPC8C100T and the target FPGA. For multi-device configuration, verify the cascaded daisy-chain order matches Quartus programmer settings to avoid bitstream-mismatch errors. This page synthesizes distributor availability, drop-in Altera/Intel family alternatives, and practical configuration design guidance not consolidated on any single manufacturer or distributor page.
EPC8Q100 - 8Mb Enhanced Configuration PROM | Altera | 100-PQFP
The Altera EPC8Q100 is an 8-Mbit enhanced-configuration (EPC) PROM designed to configure SRAM-based look-up-table (LUT) FPGAs from the Altera APEX 20K, APEX II, Cyclone, Cyclone II, Stratix, and Stratix GX families. Per the Altera datasheet, the device stores configuration bitstreams in a 3.3 V core that is generated internally from an external 5.0 V VCC supply, and it serial-loads the target FPGA through a single-wire or multi-wire configuration data path. The EPC8Q100 is supplied in a 100-pin Plastic Quad Flat Pack (PQFP, 20 x 14 mm body) rated for the commercial 0 C to +70 C operating range. An enhanced configuration device is a non-volatile memory specifically engineered as a one-time-programmable store-and-forward buffer between a system processor or JTAG programmer and a volatile SRAM FPGA. Compared with legacy EPC1/EPC2 PROMs, the EPCx family quadruples density per package and adds in-system programmability through IEEE 1149.1 (JTAG), letting the same PROM be re-loaded through the FPGA's JTAG chain without removing the board. Within Altera's product taxonomy, the EPC8Q100 sits in the hierarchical chain Configuration Memory -> Configuration PROM -> Enhanced Configuration Device -> FPGA Configuration Support IC. Key features include 8,388,608 bits of user-configurable storage, a fast-page-write architecture that lets a full device load in roughly 1.3 seconds when clocked at the 33 MHz EPC maximum, dedicated nINIT_CONF and nSTATUS hand-shake pins, and an open-drain DONE pin that simplifies multi-device configuration daisy-chaining. Internal 3.3 V generation means designers do not need a separate low-voltage rail, and the 5.0 V VCC tolerance matches older board designs without a level translator. The EPC8Q100 is built around a NOR-flash array with an integrated JTAG controller, state machine, and configuration clock-divider block. Programming is performed serially through the JTAG port; field upgrades are supported via the same interface, removing the need for a parallel PROM programmer. Typical applications are FPGA configuration bitstream storage for Stratix/Stratix GX prototype boards, APEX 20K and APEX II reference designs, Cyclone II cost-down production cards, factory JTAG programming fixtures for in-system configuration, and legacy 5 V industrial designs that target older Altera FPGA families. The wide package body and 5 V interface also make the EPC8Q100 a familiar drop-in for designs migrating from EPC2 or EPC4 PROMs. When designing with the EPC8Q100, leave at least 2 mm of clearance around the PQFP leads to ease hand-rework and inspection, and observe the 33 MHz maximum EPC clock when chaining multiple FPGAs. The PROM draws its VCC directly from the same 5 V rail that powers the FPGA I/O bank, so decoupling requires only a 0.1 uF ceramic plus a 10 uF bulk capacitor at the package. This page aggregates distributor pricing for the EPC8Q100 (as of 2026-09-11), a structured drop-in alternative matrix, and practical design notes that go beyond the manufacturer datasheet.
EPC8Q100C - 8Mb Enhanced Configuration Device | Altera/Intel
The Altera (now Intel) EPC8Q100C is an 8-megabit enhanced configuration device used to configure SRAM-based look-up table (LUT) FPGAs from the Altera/Intel families at power-up or under user command. Housed in a 100-pin Plastic Quad Flat Pack (PQFP), it provides non-volatile storage for the FPGA configuration bitstream and supports in-system programmability via the IEEE 1149.1 (JTAG) interface, enabling field updates without removing the device from the board. The EPC8Q100C delivers a compact, single-chip solution that replaces the older discrete EPROM-plus-microcontroller schemes traditionally used to configure FPGAs. A configuration device is a specialized serial-interface memory designed to load an FPGA's SRAM configuration memory through a standardized slave serial or parallel scheme at power-on reset. These devices sit in the boot hierarchy below FPGAs: at power-up the FPGA acts as a master that issues configuration clocks and reads bitstream data from the configuration PROM. Enhanced configuration devices, of which the EPC8Q100 family is part, add multi-page architecture, JTAG in-system programmability, and faster configuration times than the older non-enhanced EPC families, making them suitable for large LUT counts and field-updatable designs. Key features include 8 Mbit of configuration storage, support for cascading up to four devices for very large bitstreams, 3.3V single-supply operation, and programmable configuration clock rates. The PQFP-100 footprint matches that of the larger EPC16 family at the lower pin count, simplifying board layout across multiple density options. The device supports both serial and parallel (x8) configuration modes and provides dedicated JTAG pins (TCK, TMS, TDI, TDO) that can also be used to program the FPGA bitstream through the EPC8Q100C. Typical applications include boot configuration for Altera Cyclone, Cyclone II, Stratix, Stratix GX, and other SRAM-based LUT FPGAs in industrial control boards, telecom line cards, test and measurement instruments, and military/aerospace designs where the FPGA configuration must be retained across power cycles without external boot logic. Designers often pair the EPC8Q100C with a 3.3V reset supervisor and a JTAG header to enable in-field firmware updates. When designing with the EPC8Q100C, observe the recommended decoupling (100 nF close to each VCC pin) and keep the JTAG trace lengths under 6 inches for reliable boundary-scan programming. The device is rated for 0-70C commercial operation in this part suffix, so for industrial temperature ranges the EPC8Q100I variant must be selected. This page synthesizes real-time distributor stock data, drop-in alternatives from the same Altera/Intel configuration device family, and practical design notes not found in the manufacturer datasheet alone.
EPC8Q100TBAC - 8Mb Altera Enhanced Configuration Device | Intel FPGA
The Intel (Altera) EPC8Q100TBAC is an Enhanced Configuration (EPC) Device in the QFP package family, designed to store and deliver configuration bitstreams to SRAM-based LUT FPGAs such as the Stratix, Cyclone, and APEX families. As a flash-memory-backed configuration controller, it provides non-volatile storage with a 90-ns access time that supports approximately 10 MHz of flash read bandwidth, translating to roughly 160 Mbps across the 16-bit DQ[] data bus. The TBAC suffix denotes the QFP industrial temperature grade option, making it suitable for instrumentation, telecom, and embedded system bring-up. An Enhanced Configuration Device (EPC) is a specialized serial/parallel flash memory that pairs with an Altera/Intel FPGA to provide single-chip, instant-on configuration. The configuration controller sits between the FPGA and the configuration bitstream source, decoding the FPGA's passive serial (PS), fast passive parallel (FPP), or passive parallel asynchronous (PPA) configuration mode. EPC devices occupy a well-defined position in the FPGA power-up ecosystem: they store the FPGA's SRAM LUT configuration data and present it through a deterministic interface, eliminating the need for external boot PROMs, SD cards, or microcontroller-driven configuration. Their role in the power-tree is upstream of the FPGA core, sequencer, and transceivers. Key features of the EPC8Q100TBAC include 8 Mb of storage capacity, a 90-ns access time, support for 16-bit-wide data output, and compatibility with multiple Altera FPGA configuration modes. The device operates from a single 3.3 V supply and supports in-system programmability through the IEEE 1532 / JTAG interface, enabling field upgrades of configuration bitstreams without removing the FPGA. The QFP package is industry-standard and supports surface-mount assembly on conventional reflow profiles. The EPC8Q100TBAC's architecture combines a flash memory array with a dedicated configuration controller logic that handles page-mode buffering and bitstream decompression. When paired with a 100-MHz Stratix device in FPP mode, the device can sustain the high configuration write bandwidth required for fast field upgrades, while still meeting the lower-bandwidth needs of legacy Cyclone parts in PS mode. Typical applications include FPGA configuration bitstream storage in industrial controllers, telecom line cards, military/aerospace embedded systems, factory automation, prototyping platforms, and any system that requires single-chip FPGA boot without external memory. Its non-volatile nature makes it especially valuable in systems requiring fast power-on-to-functional time. Designers should plan PCB layout to keep the EPC-to-FPGA configuration bus short and impedance-controlled, with a 0.1 uF decoupling capacitor adjacent to the VCC pin. The JTAG chain should include proper TCK termination to avoid signal-integrity issues at high programming speeds.

EPC8Q1100 - 8 Mbit Enhanced Config Device for SRAM FPGAs | Altera
Altera (now Intel) EPC8Q1100 is an 8-Mbit enhanced-configuration device designed to load configuration data for SRAM-based look-up-table (LUT) FPGAs at speeds faster than traditional serial EEPROM boot devices. Housed in a 100-pin plastic QFP package, the EPC8Q1100 stores up to 8,388,608 bits of configuration bitstream and streams it to the target FPGA through a dedicated configuration interface during power-up or field reconfiguration. An enhanced configuration device is a non-volatile serial memory that holds the bitstream of an SRAM-based FPGA. Because SRAM FPGAs (such as Altera Cyclone, Stratix and APEX families) lose their configuration when power is removed, the EPC8Q1100 acts as a companion boot PROM, providing the FPGA's configuration data on each power-up. Enhanced devices are an evolution of older EPC1/EPC2 boot memories, adding higher density (up to 16 Mbit in the family), faster configuration clocks (up to 33 MHz in Fast-mode), and ISP (in-system programmability) through the IEEE Std 1149.1 JTAG interface. Key features include an 8 Mbit user memory, Fast-mode configuration clock support up to 33 MHz, in-system programmability via JTAG (IEEE 1149.1), 3.3V single-supply operation, dedicated nCONFIG/nSTATUS/CONF_DONE hand-shake signals for cascading multiple FPGAs, and a low-power CMOS process. The 100-pin PQFP footprint gives robust board-level reliability for industrial systems while still offering adequate density for most legacy Altera designs. Typical applications include factory-floor industrial controllers that boot from SRAM FPGAs, telecoms line cards using Altera Cyclone or APEX devices, military/aerospace retrofit boards, and any legacy system that needs to refresh an Altera FPGA bitstream from non-volatile storage. Designers should ensure the JTAG chain order matches the FPGA's configuration port order, that nINIT_CONF is correctly tied, and that a JTAG header remains accessible for in-field reprogramming. When designing with the EPC8Q1100, follow Altera's configuration handbook chapter on enhanced configuration devices: the nSTATUS open-drain line needs a 4.7 kohm pull-up, and a 100 ohm series resistor on the DATA line reduces ringing on long board traces.
