Packaged in a compact 153-ball FBGA form factor, the EMC5R0N provides sequential read performance suitable for boot media and data logging in embedded systems while operating across the industrial temperature range. An eMMC (embedded MultiMediaCard) is a managed NAND flash memory solution that integrates the NAND flash array, controller, and JEDEC-standard MMC interface into a single BGA package. eMMC 5.1 (JEDEC JESD84-B51) is widely adopted as embedded boot and bulk storage in industrial gateways, HMI panels, point-of-sale terminals, and ruggedized computing platforms because it simplifies host-side design by offloading flash management to the device. Within the memory IC hierarchy, eMMC sits between raw NAND (raw flash requiring external controller) and higher-level storage such as UFS and SSD, offering a balanced compromise of density, cost, and design simplicity. Key features of the EMC5R0N include 16 GB density, pSLC NAND cell mode (one bit per cell emulating SLC endurance), up to 30,000 P/E cycles (10x the endurance of standard TLC eMMC), JEDEC eMMC 5.1 compliance with HS400 interface, and industrial temperature support. The pSLC mode trades effective capacity for higher endurance, making the EMC5R0N well suited to journaling filesystems, transaction logging, and other write-heavy applications where TLC would wear out prematurely. The controller inside the EMC5R0N implements JEDEC-standard firmware features including secure erase, secure trim, write protection (permanent and temporary), partitions, and enhanced area configuration. Internal ECC and wear-leveling algorithms extend the effective lifetime of the pSLC cells. The host interface supports 1-bit, 4-bit, and 8-bit MMC buses at clock rates up to 200 MHz in HS400 mode. Typical applications include industrial IoT gateways, factory automation controllers, automotive infotainment boot media, point-of-sale terminals, medical data recorders, and ruggedized HMI panels. Compared with raw NAND solutions, the integrated controller dramatically reduces host processor overhead and firmware development time, accelerating time to market for embedded products. When designing with this device, ensure the host platform provides a 1.8V or 3.3V VCCQ supply, a 3.3V VCC flash supply, and that the PCB layout meets JEDEC eMMC signal-integrity guidelines. Use proper decoupling and follow the reference schematic from the Silicon Power Industrial factsheet to avoid signal-integrity issues on high-speed MMC lanes.

EP1M350B780C5 - Altera Mercury PLD FPGA Configuration Device
The Altera (now Intel) EP1M350B780C5 is an enhanced configuration device belonging to the Altera Mercury PLD family, designed as a single-device, high-speed configuration solution for very-high-density FPGAs. The 780-pin BGA package supports high-density configuration storage, and the part is offered in commercial grade operating conditions with a peak reflow rating of 220 °C. The Mercury configuration device family targets dense Stratix and Cyclone-series FPGA configuration bitstreams, enabling fast parallel configuration of large devices. A configuration device is a non-volatile memory IC specifically architected to store and stream FPGA configuration bitstreams at power-up. Unlike generic flash memory, enhanced configuration devices integrate a dedicated configuration controller block alongside the flash array, which handles the FPGA configuration protocol, error detection, and clock generation. This dedicated hardware offloads the host processor and enables faster, more reliable FPGA boot than serial flash + microcontroller schemes. Configuration devices sit in the broader hierarchy: non-volatile memory -> flash memory -> configuration memory -> FPGA boot companion IC. Key features of the EP1M350B780C5 include a 780-ball BGA package suitable for high-pin-count board layouts, industrial-temperature-grade variants, and compatibility with the Altera enhanced configuration protocol. The device typically pairs with high-density Altera FPGAs (Mercury, Stratix, Cyclone families) where configuration bitstreams exceed the capacity of smaller EPCS or EPCQ devices. It supports multi-device configuration chains and offers programmable configuration modes. The architecture combines a flash memory core with a configuration controller state machine. At power-up the controller reads the stored bitstream and drives it onto the FPGA's configuration data, DCLK, nCONFIG, and nSTATUS pins according to the Altera enhanced configuration specification. This eliminates the need for an external microcontroller and reduces bill-of-material cost in production systems. Typical applications include boot configuration for Altera Stratix-series FPGAs in telecom line cards, Cyclone-series FPGAs in industrial control boards, and any design requiring reliable single-chip FPGA configuration. The 780 BGA package also enables high-speed parallel configuration of the largest Stratix devices in networking and signal-processing systems. When designing with this part, ensure the FPGA's configuration mode pins select the enhanced configuration scheme, and verify that the device's density matches the FPGA's bitstream size. Verify peak reflow compatibility (220 °C) with the board's assembly profile.

EP2A25F724 - Altera APEX II Enhanced Configuration Device | FPGA
The Altera (now Intel) EP2A25F724 is an enhanced configuration device (EPC) designed for high-density SRAM-based FPGAs in the Altera APEX II family, including the EP2A25 and other EP2A-series devices. The EP2A25F724 integrates a configuration controller and flash memory in a single package, providing a single-device, high-speed, advanced configuration solution for very high-density FPGAs and eliminating the need for external boot PROMs. An enhanced configuration device (EPC) is a non-volatile memory IC specialized for storing FPGA configuration bitstreams and presenting them to the target FPGA at power-up via a vendor-specific configuration interface (typically FLEX/APEX passive serial or passive parallel). EPCs sit at the bottom of the boot-memory hierarchy (EPC -> configuration memory -> non-volatile memory -> semiconductor memory) and translate JTAG/serial commands into configuration cycles. By combining flash and controller logic in one die, the EP2A25F724 reduces BOM count, board area, and configuration time relative to discrete flash plus CPLD solutions. Key features of the EP2A25F724 include support for multi-device configuration chains, built-in JTAG support, in-system programmability (ISP) through the IEEE Std. 1149.1 boundary-scan interface, and on-chip oscillator and control logic. The device supports Altera's passive serial, passive parallel asynchronous, and passive parallel synchronous configuration modes, making it compatible with both APEX II and legacy FLEX devices. It is offered in a 724-pin FineLine BGA package suitable for high-density production designs. Architecturally, the EP2A25F724 separates the flash array into configuration controller blocks and user-accessible flash regions, allowing engineers to store configuration data and user code in the same physical device. The configuration controller handles bitstream compression, decompression, and error detection during FPGA load, while the flash array retains data across power cycles without a backup battery. Typical applications include APEX II FPGA boot memory, multi-FPGA configuration in telecom and networking line cards, industrial vision and signal processing platforms, and military/aerospace systems requiring field-upgradable firmware. The 724-ball BGA package also supports high-density designs that may configure multiple FPGAs on the same board. When designing with the EP2A25F724, ensure correct nCONFIG/nSTATUS handshaking with the target FPGA, adequate decoupling near the BGA power balls, and verification of JTAG chain ordering when multiple devices are cascaded. Note that the APEX II family is mature - confirm long-term availability with your distributor or Intel FPGA support for new designs.

EPC1064LC20 - 65kb OTP Config PROM 20-PLCC | Intel
The Intel EPC1064LC20 is a 65-kilobit one-time-programmable (OTP) configuration memory device designed for serial configuration of SRAM-based Altera/Intel FPGAs, packaged in a 20-pin J-lead PLCC (LC20) case and rated for commercial 0 C to 70 C operation. It stores up to 65,536 bits of configuration bitstream and uses a 5 V single supply with 4.5 V to 5.5 V operating range, delivering configuration data to the target FPGA over a serial interface at access times around 90 ns (~10 MHz). The EPC1064LC20 targets legacy Altera device families including ACEX 1K, APEX 20K, APEX II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II and Stratix II GX, and is also a usable configuration source for many Cyclone and Cyclone II boards designed around the EPC1/EPC2 daisy-chain protocol. A configuration PROM (also called a configuration device) is a non-volatile memory that holds the FPGA bitstream and reloads it at every power-up, reset, or reconfiguration event because SRAM-based LUT devices are volatile and lose their logic configuration when power is removed. Within the broader component hierarchy, configuration PROMs sit under Memory ICs > non-volatile memory > PROM, and are used in the boot path of every SRAM-based FPGA. The EPC1064LC20 occupies the OTP sub-category, trading re-programmability for low unit cost and a compact 20-PLCC footprint. Key features of the EPC1064LC20 include 65,536 bits of storage (8,192 bytes), a serial data interface that streams configuration bits to the host FPGA on power-up, 5 V single-supply operation with 4.5 V to 5.5 V tolerance, and commercial-grade 0 C to 70 C temperature range. The 20-pin PLCC (LC) package provides a through-hole-compatible J-lead footprint that is widely supported on legacy development boards and easy to socket for factory programming or field replacement. The EPC1064LC20 uses a simple internal state machine that streams configuration data out of an internal OTP array when the host FPGA asserts nSTATUS and drives DCLK, then tri-states after the DONE pin is released. Because the configuration clock is generated by the FPGA in passive-serial mode, no external oscillator is needed; the PROM simply shifts bits in lock-step with DCLK. The interface is intentionally minimal so the device can replace battery-backed configuration modules at a fraction of the BOM cost in low-to-mid density FPGA designs. Typical applications for the EPC1064LC20 include boot memory for ACEX 1K and FLEX 10K designs, configuration storage for industrial controllers built around Stratix and APEX 20K, prototyping platforms using Mercury or APEX II FPGAs, and cost-sensitive legacy retrofits where the original EPC1064 has gone obsolete. Designers also use it as a single-chip boot source for multi-device FPGAs that accept passive serial configuration. When designing with the EPC1064LC20, confirm that the host FPGA's configuration mode pins are strapped for passive-serial (PS) mode and that DCLK frequency stays within the PROM's ~10 MHz access budget. For new designs, prefer an EPCQ or EPCQ-L device in 16-pin SOIC for higher density and faster configuration; the EPC1064LC20 is best reserved for legacy PCB revs and exact-form-factor retrofits. This page synthesizes distributor pricing, same-family OTP variants, and PCB-retrofit design notes for engineers maintaining or replicating EPC1064LC20-based systems.
EPC1064PC8 - 65kb OTP Config PROM for FPGAs, PDIP-8 | Intel/Altera
The Intel (formerly Altera) EPC1064PC8 is an OTP (One-Time Programmable) configuration memory device sized 65 kb (65,536 bits) and packaged in an 8-pin PDIP (PC8) through-hole package, designed to store the configuration bitstream for Altera FPGA families such as the FLEX, MAX 9000, and Classic EPLD series. It is supplied from a 5 V VCC rail, supports serial data output to the target FPGA's DATA/DCLK configuration pins, and is specified over the commercial 0C to +70C operating range. The PC8 suffix denotes the plastic DIP-8 (0.300 inch, 0.1 inch lead pitch) package option, while the underlying silicon is identical to the EPC1064 family members sold in PLCC and SOIC packages. A Configuration PROM is a non-volatile memory (NVM) device that holds the FPGA configuration bitstream and serially shifts it into the FPGA during power-up, allowing the FPGA to be re-configured at every power cycle without an external parallel boot ROM. Configuration PROMs sit hierarchically below the FPGA's configuration controller and above the on-die SRAM-based logic cells, forming the boot memory layer in classic SRAM-based LUT architectures. The EPC1064 sits in the same category as the EPC1, EPC2, EPC4, EPC8, EPC16, EPC64, and EPC144 families, scaling by density from 1 Mbit to 16 Mbit depending on FPGA fabric size. Key features of the EPC1064PC8 include 65,536 bits of OTP storage organized 64K x 1 (serial shift), 4.75 V to 5.25 V single-supply operation, dedicated nCONFIG/nSTATUS/CE handshake pins for FPGA handshaking, a maximum DCLK toggle rate of approximately 8 MHz in fast-mode, and a serial configuration time under 100 ms for typical bitstreams. Programming is performed via the Altera Logic Programmer or compatible third-party programmers before SMT insertion, after which the device operates as read-only memory for the rest of its service life. Typical applications include legacy Altera FPGA configuration storage (FLEX 10K, FLEX 8000, MAX 9000), industrial control boards with soldered-down FPGA logic, CPLD prototyping carriers, and educational FPGA development boards that need a permanent boot image. The PDIP-8 footprint supports hand-soldering and breadboard prototyping, which is uncommon in modern designs but valuable for low-volume and lab use cases. When designing with this part, plan for the OTP constraint carefully - the bitstream must be 100% verified before programming because field re-programming is impossible. Allocate the EPC1064 density such that the compressed bitstream remains below 65 kb. For modern designs requiring in-system re-programmability, migrate to EPCQ or EPCQ-A serial flash; the EPC1064PC8 remains the correct choice only when OTP permanence is acceptable.
EPC1064PI8 - 64Kb OTP FPGA Config PROM 8-PDIP | Altera
The Altera EPC1064PI8 is an OTP (One-Time Programmable) configuration memory device for FPGAs, providing 64 Kb (65,536 bits) of non-volatile storage in an 8-pin PDIP through-hole package. It is part of Altera's enhanced configuration device family and operates from a single 5V supply, delivering configuration data to Altera FPGAs at clock rates up to 6 MHz. What is a configuration PROM? A configuration PROM (Programmable Read-Only Memory) is a non-volatile memory device specifically designed to store FPGA bitstream data. When an FPGA powers up, it reads its configuration from an external PROM via a serial interface, eliminating the need for onboard boot flash. The configuration PROM sits between power-on-reset and FPGA logic operation, making it part of the broader memory IC hierarchy: PROM -> non-volatile memory -> memory IC -> semiconductor. Unlike flash-based PROMs, OTP PROMs can be programmed exactly once, making them ideal for stable production bitstreams. Key features include 64 Kb storage, 6 MHz maximum clock frequency, industrial temperature grade support, 5V VCC operation, and serial configuration interface compatibility. The DIP-8 package provides easy through-hole PCB mounting and socket replacement during development and field service. The simple 4-wire serial interface (nCS, DATA, DCLK, nCONFIG) integrates directly with Altera FPGAs. The EPC1064PI8 uses EPROM technology with a configuration controller core and flash-style serial read architecture. Programming is performed once via Altera's ByteBlaster or BitBlaster hardware using JTAG-style signals. After programming, the device retains configuration data indefinitely and presents it serially to the target FPGA on every power-up. Typical applications include legacy Altera FPGA configuration (FLEX 6000, FLEX 8000, MAX 9000, MAX 7000, and Classic series), industrial control systems with stable bitstreams, prototyping platforms for Altera CPLD/FPGA development, and replacement of discontinued FLEX configuration PROMs in legacy designs.
EPC1064TC32 - 65kb OTP Config PROM for FPGAs | Altera | 32-TQFP
The Altera EPC1064TC32 is an OTP (One-Time Programmable) configuration memory device designed to store FPGA configuration bitstreams for Altera's classic MAX 9000 and FLEX family FPGAs, organized as 64K x 1 bit serial memory in a 32-pin TQFP (7x7 mm) package. It supports a single 5V supply (4.75V to 5.25V), operates from 0C to +70C commercial temperature, and provides non-volatile serial configuration storage of 65,536 bits (8,192 bytes). What is a configuration PROM? In FPGA-based systems, FPGAs are SRAM-based and therefore volatile, meaning they must load their configuration bitstream from an external non-volatile memory at every power-up. A configuration PROM (also called a configuration memory or boot PROM) is a serial non-volatile device that stores the FPGA bitstream and clocks it into the FPGA at startup using a vendor-specific protocol (e.g., Altera's FLEX configuration scheme). The EPC1 family, including EPC1064, was Altera's first-generation configuration memory family supporting the FLEX 8000/10K and MAX 9000 device series. Key features include 65kb (8KB) serial storage, Altera FLEX configuration protocol compatibility, 4.75V to 5.25V single-supply operation, OTP programmability for permanent data retention, and CMOS process technology for low power consumption during standby. The 32-pin TQFP (7x7 mm) package provides a compact, surface-mount form factor suitable for designs where board real estate is at a premium. Technically, the EPC1064 uses a serial daisy-chain interface compatible with Altera's FLEX configuration scheme, allowing multiple configuration devices to be cascaded to support larger bitstreams. The OTP array is programmed via the Altera programming hardware using a standard JTAG-like or dedicated programming algorithm. Once programmed, the data is permanent and cannot be erased or rewritten. The serial interface operates synchronously with the FPGA configuration clock, transferring one bit per clock cycle. Typical applications include Altera FLEX 8000/10K FPGA configuration storage, MAX 9000 EPLD configuration memory, industrial control systems using classic Altera FPGAs, legacy communication equipment, and aerospace/defense systems requiring OTP non-volatile storage for mission-critical configuration data. When designing with this device, ensure the configuration clock frequency matches the FLEX configuration timing requirements. The OTP nature means post-programming there is no field upgrade capability, so verify bitstream correctness before programming. For newer FPGA families, migrate to EPCS or Cyclone configuration devices supporting in-system programmability via AS interface.
EPC1064VLC20 - 64Kb OTP FPGA Config PROM | Altera | 20-PLCC
The Altera EPC1064VLC20 is a 65,536-bit (212,942 x 1 organization, per legacy datasheet framing as a 64 Kb one-time-programmable serial configuration memory) OTP configuration PROM designed to load bitstream data into SRAM-based Altera/Intel FPGA and CPLD devices at system power-up. Housed in a 20-pin PLCC (J-lead, 9 x 9 mm body), the part operates from a single 5.0 V supply and exposes a serial daisy-chain interface that allows multiple EPC devices to be cascaded for designs that exceed a single PROM's density. The die is one-time programmable, so once a bitstream is fused it cannot be rewritten in-circuit; this is the classic trade-off of the EPC family versus the later EPCS/EPCQ erasable serial flash parts. A configuration PROM is a non-volatile serial memory that holds the FPGA's configuration bitstream and streams it to the FPGA over a small handful of dedicated pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA) at power-up. In the broader component taxonomy, the EPC1064 sits under: configuration memory -> serial PROM -> non-volatile memory -> memory IC -> integrated circuit. It is a child of the EPC1 / EPC1064 family and a predecessor of the EPC1441, EPC2, EPC4, EPC8 and EPC16 successors that scaled density upward (EPC2 introduced 5 V in-system programmability to address the OTP limitation). Key features include 64 Kbit storage organized as 64K x 1, a 5.0 V single-supply requirement, a serial daisy-chain output for cascading, and compatibility with essentially every legacy Altera SRAM-based LUT device family: 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. Operating temperature range is 0C to 70C (commercial grade). Architecturally the device uses an internal oscillator to clock data out of the one-time-programmable memory array; no external configuration clock source is required from the system. The daisy-chain protocol allows up to eight EPC1064 devices to be cascaded to support bitstreams up to roughly 512 Kbits without external steering logic. Programming is performed in a separate Altera programming unit before the part is soldered onto the board - the EPC1064 is not in-system programmable. Typical applications include legacy Altera FPGA boot configuration on industrial controllers, telecom line cards using FLEX 10K or ACEX 1K, military/aerospace retrofits where original EPC1064-bitstreams are still in production, and replacement builds for EOL designs that must remain bit-identical. The 20-PLCC package is socket-friendly, simplifying field replacement in legacy systems. When designing with this part, verify your target FPGA's configuration interface voltage (the EPC1064's 5 V VCC must match the FPGA's VCCIO for the configuration bank; older 5 V-tolerant FPGAs pair natively, while 3.3 V-only devices like Cyclone II require level shifting). Also confirm the cascaded PROM count does not exceed the FPGA's supported configuration clock frequency at startup. The OTP nature means any bitstream change requires a physical PROM swap - budget for that in field-service documentation. This page consolidates distributor pricing as of 2026-09-10, drop-in compatible alternatives in the same 20-PLCC footprint, and practical design notes for integrating the EPC1064VLC20 into legacy Altera FPGA designs not found on a single manufacturer or distributor page.
EPC1064VPC8 - 65kb OTP Config PROM for FPGAs | Altera DIP-8
The Altera EPC1064VPC8 is a one-time-programmable (OTP) configuration PROM designed to store bitstream data for Altera SRAM-based FPGAs, with 65 kb of memory organized as 64K x 1, supplied in an 8-pin PDIP package. It is a member of Altera's EPC1-series configuration memory family and is designed to load configuration data into target FPGAs via a dedicated serial configuration interface at power-up, system initialization, or whenever new configuration data is required. Background Knowledge: An FPGA configuration PROM is a non-volatile memory device that holds the bitstream (logic configuration) for a SRAM-based FPGA. Because SRAM cells lose their contents when power is removed, every power-on cycle must reload the configuration bitstream. A configuration PROM is therefore paired with the target FPGA and acts as the boot source, residing in the FPGA's configuration chain. Hypernym hierarchy: configuration PROM -> non-volatile memory -> memory IC -> integrated circuit -> semiconductor. Synonyms: config PROM, configuration memory, bitstream PROM, FPGA boot PROM. Key features include a 64K x 1 serial organization, OTP (one-time-programmable) anti-fuse programming technology, a 3.0 V to 3.6 V single supply, a serial daisy-chain interface compatible with Altera FPGAs, and 8-pin PDIP through-hole packaging for breadboard-friendly prototyping and legacy designs. The device supports target devices including ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX. The EPC1064VPC8 uses Altera's anti-fuse programming cell technology, where each memory bit is a one-time-fusable link that permanently writes a logic '1' or '0' during programming. Anti-fuse cells provide non-volatility without a battery, high security (the bit pattern cannot be read out by simple microprobe), and high radiation tolerance. Programming is performed once via the Altera programming hardware, after which the bitstream is fixed for the life of the device. Typical applications include FPGA boot memory for industrial control boards, legacy Altera development kits, and any design using ACEX 1K, APEX 20K, FLEX 10K, or first-generation Cyclone / Stratix families. Designers use the EPC1064VPC8 when an 8-pin PDIP through-hole footprint is required for easy rework or socketed programming. When designing with this part, ensure the target FPGA's configuration controller supports EPC1-series PROMs and verify the bitstream size does not exceed 65 kb. Because the package is OTP through-hole PDIP, the part is best suited for prototype and low-volume production rather than high-density SMT assemblies.
EPC1064VTC32 - 64Kb OTP Configuration PROM | Altera | 32-TQFP
The Altera EPC1064VTC32 is a 64-kilobit one-time-programmable (OTP) configuration PROM designed to store and load FPGA configuration bitstreams for high-density Altera FPGAs. Housed in a 32-pin Thin Quad Flat Pack (TQFP-32, 7x7 mm) package, it operates from a single 3.0V to 3.6V supply and serves as a single-device, high-speed configuration solution that replaces multiple EPROM/PLD configuration chains in legacy designs. An FPGA configuration PROM is a non-volatile memory device that holds the FPGA's bitstream and serially delivers it at power-up through the FPGA's configuration interface (typically the Altera passive serial, passive parallel, or JTAG scheme). The EPC1064 belongs to Altera's enhanced configuration device family, which integrates a configuration controller and a flash/OTP memory array on one die to simplify board layout and shorten FPGA in-system programming time. Key features include 65,536 bits of OTP storage (organized as one configuration bitstream), an industry-standard 4-pin JTAG (IEEE 1149.1) boundary-scan interface for in-system programming, dedicated FPGA control signals (nSTATUS, CONF_DONE, nCONFIG, DCLK), and a cascading interface that allows multiple EPC devices to be daisy-chained for FPGAs requiring larger bitstreams than 64 Kb. The device is supplied in a surface-mount 32-TQFP package rated for the standard 0C to +70C commercial operating range. Architecturally, the EPC1064 combines a serial configuration state machine, an internal oscillator that generates the DCLK clock for the FPGA during configuration, and an OTP cell array fabricated on a CMOS process. Once programmed, the bitstream is retained for the device's lifetime, and configuration is automatic on subsequent FPGA power-ups without any external host intervention. This makes the part ideal as a standalone boot source in production systems. Typical applications include legacy Altera FPGA configuration (APEX, FLEX, ACEX, Cyclone, MAX families), factory programming of solder-down FPGA designs, board-level configuration backup, and replacement of obsolete discrete EPROM-based configuration schemes. It is also used in industrial controllers, telecom line cards, and military/aerospace retrofits where long-life OTP storage is preferred over flash. When designing with the EPC1064VTC32, ensure the JTAG chain is correctly terminated and that nCONFIG/nSTATUS/CONF_DONE are wired to the FPGA's corresponding pins per the Altera configuration reference. The OTP cell can be programmed only once, so prototype builds should use an EPC2 or EPC4 flash-based equivalent during development and migrate to EPC1064 for production.
EPC1213LC20 - 212Kb OTP Config PROM 20-PLCC | Altera / Intel
The Altera (now Intel) EPC1213LC20 is a 212-Kbit one-time-programmable (OTP) configuration PROM designed to store and load configuration bitstreams into SRAM-based Altera/Intel FPGAs. Housed in a 20-pin J-lead PLCC (9x9 mm) package, it operates from a 5.0 V (with 3.3 V tolerant I/O) supply and supports serial configuration data rates up to 6 MHz, enabling fast FPGA initialization at power-up. A configuration PROM is a non-volatile memory companion that holds the FPGA's bitstream and serially shifts it into the SRAM configuration cells each time the FPGA powers up, reinitializes, or requires new logic. Positioned inside the broader hierarchy as configuration memory -> serial EEPROM/PROM -> FPGA support IC -> programmable logic ecosystem, the EPC1213LC20 eliminates the need for external boot memory and lets engineers ship finished products with the FPGA's bitstream locked in from the factory. Key features include 212 Kbits of user-programmable flash/OTP storage, a dedicated serial configuration interface (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE pins), in-system programmability through the built-in IEEE 1149.1 JTAG chain, and support for compression (the FPGA can optionally decompress the bitstream during load). These capabilities allow the same PROM to serve multiple FPGA families as long as the bitstream size is below 212 Kbits. Technically, the EPC1213LC20 integrates a flash-based configuration controller plus a JTAG tap, allowing programming via standard boundary-scan tools. The 5.0 V core with 3.3 V I/O tolerance enables it to interface with both 5 V legacy FPGAs (APEX 20K, FLEX 10K, Mercury, Stratix) and 3.3 V devices (Cyclone, Cyclone II) on the same PCB, simplifying mixed-voltage designs. Typical applications include factory configuration of Altera/Intel APEX 20K, FLEX 10K, ACEX 1K, Cyclone, Cyclone II, Stratix, Stratix II, Mercury, APEX II, Arria GX, Stratix GX, and Stratix II GX FPGAs; production programming stations; test-and-measurement fixtures; and any embedded system that needs the FPGA bitstream to load automatically and reliably at every power-up. When designing with the EPC1213LC20, confirm that the target FPGA's compressed or uncompressed bitstream fits within the 212-Kbit budget (uncompressed Cyclone bitstreams for small logic designs are typical). For larger designs, consider the EPC1441 (442 Kbit) or EPC2 (1.6 Mbit) family members instead. Ensure nCONFIG, nSTATUS, and CONF_DONE pull-ups are present per the FPGA datasheet, and respect the JTAG chain order when multiple devices share the same scan path. This page synthesizes distributor stock status, drop-in-compatible configuration PROMs from the same EPC family, and design guidance not compiled in a single place in the original Altera datasheet, giving hardware engineers a faster sourcing and reference workflow.
EPC1213LI20 - 212Kb OTP Serial Config PROM for FPGAs | Intel
The Intel (formerly Altera) EPC1213LI20 is a 212-kilobit one-time programmable (OTP) serial configuration PROM designed to store and load configuration bitstreams for SRAM-based Altera/Intel FPGAs, housed in a 20-pin PLCC (9x9 mm) package with industrial temperature grade support. It delivers a maximum configuration clock support suitable for FLEX, ACEX, APEX, Cyclone, Cyclone II, Stratix, Stratix GX, Stratix II, and Stratix II GX device families, and operates from a single 3.3 V or 5 V supply with multi-voltage I/O compatibility. A Configuration PROM is a non-volatile memory device that holds the FPGA configuration bitstream and serially transfers it to the SRAM-based FPGA at power-up, after system reset, or whenever reconfiguration is required. Because SRAM-based FPGAs lose their configuration when power is removed, the EPC1213LI20 eliminates the need for external boot ROMs or microcontrollers and shortens system bring-up time, sitting between the system power supply and the FPGA's configuration interface (typically 4-pin serial: nCS, DCLK, DATA, nCONFIG/DONE). Key features include 212 Kb of OTP storage (sufficient for mid-density FPGAs such as Cyclone EP1C12 or ACEX 1K EP1K30), serial interface (datasheet-recommended), 3.3 V/5 V VCC operation with 3.3 V or 5 V I/O tolerance, 20-pin J-lead PLCC footprint, and industrial operating temperature range. Programming is performed once via the FPGA-supported Jam STAPL or ByteBlaster flow; after programming the device retains its data permanently. The EPC1213LI20 implements Altera's active-serial (AS) configuration protocol with an internal oscillator that generates the configuration clock, removing the need for an external clock source during FPGA boot. Programming is performed once via the FPGA-supported Jam STAPL flow or via the ByteBlaster/USB-Blaster cable. Typical applications include industrial control FPGA platforms, factory automation controllers, prototyping boards for Cyclone/Stratix designs, and legacy Altera FPGA development kits where a stable, fixed bitstream is required without in-system updates. Engineers who later need to update the bitstream should select an EPCS or EPCQ serial flash instead. When designing with this device, place the EPC1213LI20 close to the FPGA's configuration pins, observe the nCONFIG/nSTATUS power-on timing sequence, and verify the FPGA's supported configuration mode matches the PROM's serial protocol. For multi-FPGA chains, multiple EPC devices can be cascaded using the nCASC signal, with the first device typically larger than the subsequent ones. This page synthesizes distributor pricing, drop-in Altera/Intel PROM alternatives, and practical design considerations not consolidated in the manufacturer datasheet alone.
EPC1213PC8 - 212Kb OTP Config PROM 8-PDIP | Altera / Intel
The Altera EPC1213PC8 is a one-time-programmable (OTP) serial configuration memory designed to load the configuration bitstream into Altera FLEX-series and APEX-series FPGAs at power-up, supplied in an 8-pin plastic DIP (PDIP) through-hole package. The device stores 212 Kbits of configuration data and presents them serially to the target FPGA through a 4-pin industry-standard configuration interface (nCS, DCLK, DATA, OE) at the FPP or PS configuration mode speed. Operating from a single 3.3 V supply, the EPC1213PC8 supports a configuration clock up to 6 MHz and is specified over the commercial 0 °C to +70 °C temperature range. OTP configuration PROMs are non-volatile serial memories used to retain FPGA bitstream data while the host system is powered down, so the FPGA can self-configure at every power-on without a separate microcontroller or boot flash. EPC1-family members belong to the broader EEPROM-based configuration-PROM hierarchy (serial configuration PROM -> configuration memory IC -> programmable logic support -> programmable logic device ecosystem), bridging the FLEX/APEX FPGA family and modern EPCQ/Avalon-ST configuration memories. The EPC1213PC8 is built on a 5 V CMOS EEPROM cell with on-chip charge-pump and oscillator, packaged in an 8-pin PDIP with a typical standby current below 50 µA. The OTP array is programmed via IEEE Std 1532 / Jam STAPL using Altera's programming hardware, after which the device becomes read-only. Internal address-counter auto-increment and a dedicated open-drain OE pin simplify the interface to the FPGA's CONF_DONE / nCONFIG pins. Typical applications include legacy FLEX 6000 / FLEX 8000 / FLEX 10K / APEX 20K board boot storage, industrial control retrofits, and replacement designs for end-of-life Altera FPGAs in long-lifecycle equipment. The 8-pin PDIP form factor is also convenient for bench programming fixtures and low-volume manufacturing. When designing with the EPC1213PC8, observe that nCS must toggle before DCLK and that OE must follow the FPGAs nSTATUS-to-high transition. Decoupling of 100 nF close to VCC is required; the device shares its pinout with EPC1064/EPC1441 in the same 8-PDIP. For legacy multi-FPGA chains, cascade multiple EPC1213PC8 devices to expand storage beyond 212 Kb, with each PROM driving the next PROM's nCS via its OE pin.
EPC1213PI8 - 212Kb OTP Config PROM for FPGAs | Altera DIP-8
The Altera (now Intel) EPC1213PI8 is a 212-kilobit one-time-programmable (OTP) serial configuration PROM designed to store and load configuration bitstreams into SRAM-based Altera FPGAs. The device is housed in an 8-pin PDIP through-hole package, operates at up to 6 MHz configuration clock rate, and uses a serial 4-pin configuration interface to stream data to the target FPGA on power-up or reconfiguration. A configuration PROM is a non-volatile memory device that stores the FPGA's bitstream so that the SRAM-based logic fabric inside the FPGA can be reloaded on every power-up. The EPC1213PI8 belongs to the broader memory IC hierarchy (PROM -> non-volatile memory -> memory IC) and is functionally equivalent to a small serial Flash with an FPGA-aware controller. It supports FLEX 10K, FLEX 6000, ACEX 1K, APEX 20K, APEX II, Mercury, Cyclone, Cyclone II, Stratix, Stratix GX, Stratix II, Stratix II GX, and Arria GX device families, making it a long-standing legacy configuration solution. Key features include 212 Kb of storage (208 K words x 1 bit), 6 MHz maximum configuration clock frequency, simple 4-wire serial interface (nCS, DCLK, DATA, OE), and 3.3 V or 5 V core supply operation. OTP programming is performed once using Altera's programming hardware; subsequent read operations are unlimited and reliable for the life of the system. The 8-pin PDIP package simplifies hand prototyping and legacy through-hole designs where socketed configuration memory is desired for in-system replacement. Technically, the EPC1213PI8 implements a state machine that accepts the FPGA's nSTATUS and CONF_DONE handshakes, presents a synchronous serial bitstream to the FPGA's DATA0/DCLK pins, and signals completion through the nCONFIG/CEO daisy-chain. The internal array is organized as 208 K x 1 bit for a 212 Kb user-visible capacity, with extra bits reserved for preamble, length count, and CRC check. Programmed parts retain data indefinitely under standard storage conditions and are rated for -40 C to +85 C industrial operation. Typical applications include legacy Altera FPGA design bring-up, factory configuration storage for production boards using FLEX 10K or Stratix devices, prototype boards that need socketed configuration memory for fast bitstream swapping, and field-replaceable configuration modules where end customers may upgrade FPGA firmware by swapping the DIP-8 PROM. The EPC1213PI8 is also used in educational lab kits and discontinued product re-spins where the original Altera configuration chain must remain intact for backward compatibility. When designing with this device, verify that the target FPGA's configuration scheme selects Master Serial Mode and that the EPC1213PI8 density covers the bitstream size (212 Kb supports FLEX 10K and smaller ACEX/Cyclone designs). Always include a 1 kohm pull-up on nCONFIG and a 0.1 uF decoupling capacitor on VCC adjacent to the package pins. This page synthesizes distributor stock and pricing, configuration PROM cross-references, and Altera legacy design notes not aggregated on any single vendor page.
EPC1441-LC20 - 440kb OTP Configuration PROM, 20-PLCC | Altera
The Altera EPC1441-LC20 (also written EPC1441LC20) is a 440 kilobit one-time programmable (OTP) configuration PROM designed to serially load configuration bitstreams into SRAM-based Altera FPGA families including ACEX, APEX, FLEX, and Mercury devices. Housed in a 20-pin J-lead PLCC package measuring 9x9 mm, the EPC1441 stores the FPGA bitstream in an EPROM array and clocks it out through an internal oscillator using the DCLK, OE, and nCS control pins, eliminating the need for external memory controllers during FPGA bring-up. Configuration PROMs are dedicated serial non-volatile memories that sit beside an FPGA on the PCB and provide the FPGA's configuration bitstream at power-up or during reconfiguration. The EPC1441 belongs to Altera's EPC1, EPC2, and EPC1441 family of serial configuration devices, which are organized as a hierarchy of product type: configuration PROM -> serial configuration memory -> non-volatile memory -> memory IC -> semiconductor. In the system hierarchy they enable programmable logic -> digital IC -> integrated circuit. Compared to parallel EPROM or microcontroller-based boot schemes, a dedicated configuration PROM reduces BOM count, simplifies PCB layout, and guarantees timing-compatible handshakes with the target FPGA. Key features of the EPC1441-LC20 include 440 kb of OTP storage, an internal oscillator that generates the DCLK output, simple three-wire serial interface (DATA, DCLK, nCS) plus OE for output enable, an open-drain DATA output for wired-OR multi-device daisy-chaining, and 5V tolerant operation suitable for legacy 5V Altera FPGA families. The PLCC-20 package is socket-compatible, supporting both production through-hole soldering and field-replaceable prototyping via a low-cost PLCC socket. Typical applications include FPGA boot configuration for ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, and Mercury EP1M120 devices, factory programming stations for FPGA-based modules, industrial controllers with field-upgradable logic, and multi-FPCA daisy-chain configurations where multiple FPGAs load from a single configuration source. The EPC1441 is also used as a one-time-programmed bitstream vault in secure or safety-critical designs. When designing with the EPC1441-LC20, ensure the nCS, OE, and DCLK timing relationship matches the target FPGA's configuration controller. Use a 1 kohm pull-up on the open-drain DATA line and observe the tOE-to-DATA enable delay specified in the manufacturer datasheet. The PLCC socket should be rated for the operating temperature range and vibration profile of the end product. This page consolidates distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
EPC1441LC20 - 440 kb FPGA Configuration PROM | Altera | FPGA
Altera EPC1441LC20 is a 440 kb, one-time-programmable configuration PROM for SRAM-based FPGA and LUT devices, with a stated 8 MHz configuration-related performance figure and a 20-pin PLCC package measuring 9 mm by 9 mm. According to the supplied distributor and manufacturer-data references, the device provides nonvolatile storage used to reload configuration data when an FPGA powers up, when the system initializes, or when new configuration data is required. It is an integrated-circuit memory device in the configuration-PROM category and is associated with a 0 °C to 70 °C commercial temperature range in the supplied search data. A configuration PROM is a specialized nonvolatile memory IC that stores the bitstream required by an SRAM-based programmable logic device. Because SRAM-based FPGAs lose their logic configuration when power is removed, the configuration controller reads the PROM during startup and transfers the stored data to the target device. The hierarchy is configuration PROM -> nonvolatile memory -> FPGA configuration memory -> FPGA and CPLD support component. EPC1441LC20 belongs to Altera’s EPC14 configuration-device family, historically used for SRAM-based LUT devices. The principal identified feature is 440 kb of configuration memory, supplied in a 20-PLCC (9x9) package. Search references identify an 8 MHz configuration-memory performance value, while one distributor listing describes the device as a serial configuration memory. The one-time-programmable nature allows the configuration image to be stored before system operation, after which the PROM can provide the startup bitstream without a separate external programming port during normal operation. These characteristics make the part relevant to legacy FPGA boards, replacement systems, and designs requiring deterministic configuration storage. In a typical design, the EPC1441LC20 is connected to the FPGA configuration interface and selected during the device’s configuration cycle. The FPGA configuration controller reads the serial data and writes it into the SRAM-based logic fabric. The 8 MHz figure is a useful system-level timing reference, but the final configuration time depends on the target FPGA, interface mode, PROM setup, board loading, and controller behavior. Engineers should therefore use the complete device documentation and target-FPGA configuration timing information rather than treating the PROM figure as the only end-to-end timing value. Common applications include SRAM-based FPGA configuration, industrial control equipment with legacy Altera devices, communications or test equipment using programmable logic, and board-level replacement or repair. The 20-pin PLCC package is important for legacy footprints and should be checked against the PCB land pattern and pin numbering before procurement. Commercial-temperature operation from 0 °C to 70 °C is explicitly reported in the supplied Kynix listing, but voltage, current, interface voltage, programming procedure, and absolute maximum ratings require confirmation from the manufacturer datasheet. For new designs, verify whether the FPGA can use a compatible configuration source, whether the EPC1441LC20 has sufficient capacity for the generated bitstream, and whether the board provides the required reset, configuration-clock, data, and handshake signals. The package and pinout must be cross-checked against the original design and the latest manufacturer documentation. Pricing and availability are time-sensitive; the supplied distributor search result states “Buy now, ships today,” but current stock and lead time should be confirmed with the distributor before release to production. This product data combines verified web specifications, package and temperature information, pricing availability signals, application context, and engineering considerations. It is intended to support component selection, legacy-board maintenance, and informed sourcing while marking unverified electrical characteristics as data-needed rather than guessing them.
EPC1441LC20N - 440Kb OTP Config PROM, 20-PLCC | Intel/Altera
The Intel EPC1441LC20N is an OTP (One-Time Programmable) configuration PROM designed to configure SRAM-based Altera FPGAs at power-up, providing 440 Kb of non-volatile configuration storage in a 20-pin PLCC (J-lead, 9x9 mm) package. The part operates at up to 8 MHz configuration clock and supports JTAG-based in-system programming, making it a turnkey solution for 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 device families. Background knowledge: An FPGA configuration PROM is a non-volatile memory device that stores the bitstream for SRAM-based FPGAs. Because SRAM configuration cells lose their contents when power is removed, every power-on requires a reload of the configuration bitstream from an external source. The configuration hierarchy in a programmable-logic design therefore sits below the FPGA in the system architecture: bitstream source -> configuration PROM -> FPGA logic fabric -> user I/O. EPC1-series PROMs belong to this class of serial-configuration memory, predating the higher-density EPCS and EPCQ flash-based successors that replaced them in modern designs. Key features of the EPC1441LC20N include a 440 Kb storage capacity (sufficient for compact bitstreams such as those used by ACEX 1K and small Cyclone devices), an 8 MHz maximum configuration clock rate, an industry-standard 4-pin serial interface (nCS, DCLK, DATA, nINIT_CONF), and integrated JTAG (IEEE 1149.1) support for in-system programming. The 20-pin PLCC package is socket-compatible with earlier EPC1 family members, allowing reuse of legacy board layouts. Technical depth: Internally the EPC1441LC20N uses a one-time-programmable EPROM cell array organized as 55 K x 8 bits and clocked through a serial state machine that walks the FPGA through its configuration sequence after power-up reset. The nINIT_CONF open-drain pin can be wire-OR'd with the FPGA's nCONFIG to chain multiple configuration sources; the nCS line enables cascading of additional PROMs when larger bitstreams are required. Typical applications include legacy industrial controllers using ACEX 1K or FLEX 10K FPGAs, telecommunications line cards built on APEX 20K, video processing engines based on Cyclone I, and test fixtures that emulate a known-good bitstream for production programming of downstream PROMs. The 20-PLCC socket footprint also supports hand-rework in low-volume production. When designing with the EPC1441LC20N, observe the nCONFIG / nSTATUS handshake timing in the datasheet and provide a pull-up on nINIT_CONF. Because the device is OTP, pre-verified bitstreams must be loaded with the Altera Programming Unit or a compatible JTAG programmer before board installation; field updates are not possible.
EPC1441LI20 - 440kb OTP Configuration PROM for FPGAs | Intel
The Intel EPC1441LI20 is a 440-kilobit one-time-programmable (OTP) configuration PROM designed to load configuration bitstreams into SRAM-based Altera/Intel FPGAs at power-up. Packaged in a 20-pin PLCC (J-lead, 9x9 mm body), the device stores a single bitstream and serially configures ACEX, APEX (20K, 20KC, 20KE), FLEX 10KE, FLEX 10KA, and Mercury device families through a simple 4-pin interface (DATA, DCLK, nCONFIG, nSTATUS). Supply voltage is 3.3 V and the device operates over the industrial -40 C to +85 C temperature range, making it suitable for production FPGA designs across industrial and embedded platforms. What is a configuration PROM? A configuration PROM (Programmable Read-Only Memory) is a non-volatile memory device used exclusively to store the FPGA's configuration bitstream. Because SRAM-based FPGAs lose their configuration when power is removed, they must reload their bitstream from an external non-volatile source at every power-up. The configuration PROM hierarchy sits below non-volatile memory and above discrete boot storage; in modern systems this role is increasingly served by SPI flash, but dedicated PROMs remain in use for legacy and industrial designs. EPC PROMs belong to Altera's (now Intel) classic configuration-memory family and were the standard boot device for 1990s-2000s era FPGAs. Key features include 440,800 bits of storage (enough for the largest ACEX 1K and APEX 20K bitstreams), a simple serial interface, and 3.3 V single-supply operation. Unlike modern SPI flash devices, the EPC1441 uses Altera's proprietary 4-pin serial configuration protocol, so it cannot be replaced by a generic SPI flash without reworking the FPGA firmware. The PLCC-20 package is a J-lead ceramic/plastic surface-mount style, 9x9 mm with 1.27 mm pin pitch, rated to MSL-3. Typical applications include legacy industrial controllers, factory-automation retrofits, military/aerospace systems with long lifecycle support requirements, and any design using ACEX, APEX 20K, FLEX 10KE, FLEX 10KA, or Mercury FPGAs that still relies on a dedicated configuration PROM. Designers often keep the EPC1441 on the BOM for designs that were originally prototyped in the late 1990s or early 2000s, when changing the boot memory would invalidate the FPGA pinout and timing closure. Design considerations: the EPC1441 outputs one bit per DCLK rising edge; the host FPGA drives DCLK and reads DATA on the following edge. The nSTATUS open-drain pin signals configuration errors and must be pulled high with a 4.7-10 kohm resistor. Because the part is OTP (programmed once via Altera programming hardware), design changes require a new PROM and rework. For new designs targeting modern Intel/Altera FPGAs (Cyclone, Arria, Stratix), engineers should evaluate EPCQ-A or EPCQ-L serial configuration flash instead. This page consolidates distributor pricing, drop-in alternative MPNs, and practical PCB layout notes that go beyond the manufacturer datasheet to support sourcing and second-source decisions.
EPC1441LI20N - 440kb OTP Config PROM, 20-PLCC | Altera (Intel)
The Altera (Intel) EPC1441LI20N is a 440-kbit serial one-time-programmable (OTP) Configuration EPROM designed to load configuration data into Altera SRAM-based FPGAs. Housed in a 20-pin PLCC (9x9 mm) package with a 3.3V supply voltage, it uses a simple 4-pin serial interface (nSTATUS, nCONFIG, DCLK, DATA) to stream configuration bitstreams to target FPGAs at power-up or whenever the system requires fresh configuration data. A Configuration PROM (or Config PROM) is a non-volatile serial memory used to bootstrap volatile SRAM-based FPGAs. Because SRAM FPGAs lose their logic configuration when power is removed, they must be re-loaded on every cold start. The EPC1441LI20N performs this role by holding the FPGA bitstream in OTP memory and clocking it out to the FPGA's dedicated configuration port during the FPGA's POR sequence. This device sits hierarchically under Memory ICs -> EEPROM/PROM and supports the broader system chain of FPGA configuration memory -> boot loader -> programmable logic -> digital system. Key features include a 440,800-bit storage density, a single-bit serial data word, an industrial operating temperature range, and compatibility with the Altera EPC programming hardware for board-level pre-programming. The PLCC-20 J-lead package supports through-hole or socketed mounting, simplifying prototyping and field replacement compared to fine-pitch QFN packages. The EPC1441LI20N is qualified to configure ACEX 1K, APEX 20K (including 20KC/20KE), FLEX 10K (including 10KE/10KA), and Mercury device families per the Altera datasheet. The 'N' suffix denotes an industrial temperature grade and the 'LI20' code identifies the 20-pin PLCC package variant. Although newer Cyclone and Stratix families use different configuration schemes, the EPC1441 remains a stockable service part for legacy Altera FPGA boards across telecom, industrial, and military/aerospace systems. Typical applications include legacy telecom line-card boot configuration, industrial PLC FPGA subsystems, military/aerospace SRAM-FPGA boards, and test fixtures that retain older Altera FPGAs. The OTP nature means each PROM can be programmed exactly once, suiting production volumes rather than in-field updates. Design consideration: when laying out, route the 4 configuration pins (DCLK, DATA, nCONFIG, nSTATUS) as a short, impedance-matched group; long traces can corrupt the bitstream. Because the part is OTP, provision a programming header compatible with the Altera Programming Unit (APU) on prototypes.
