EPC1064VPC8 Overview
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.

Typical Applications
EPC1064VPC8 is suitable for 6 applications: Legacy Altera FPGA Boot Memory, Industrial Control Board Configuration, Prototype and Development Board Bitstream Storage, Aerospace and Defense Bitstream Storage, Telecommunications Line Card Configuration, Test and Measurement Equipment Firmware Boot.
Legacy Altera FPGA Boot Memory
The EPC1064VPC8 serves as the primary bitstream source for ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, and early Cyclone / Stratix FPGAs. Its 65 kb OTP capacity fits the largest bitstreams of these legacy devices, and the Altera serial configuration interface (nCS, DCLK, DATA, OE) is hardware-compatible with the FPGA's configuration controller. Placed adjacent to the FPGA on the PCB with a 4.7 uF decoupling cap on VCC, the device delivers the bitstream at power-up, enabling deterministic FPGA boot without external processor intervention.

Recommended
Industrial Control Board Configuration
In industrial control applications using FLEX 10K or APEX 20K FPGAs, the EPC1064VPC8 stores the deterministic control logic that must survive power-cycles without reprogramming. Its anti-fuse OTP technology provides high immunity to bit-flip events in electrically noisy factory environments, and the 3.3 V supply aligns with industrial 3.3 V rails. Unlike reprogrammable flash, the OTP bitstream cannot be altered by stray writes or EMI, which is critical for safety-related control logic. Source: manufacturer datasheet.
Recommended
Prototype and Development Board Bitstream Storage
The 8-pin PDIP through-hole package of the EPC1064VPC8 makes it ideal for prototype and development boards. Engineers can socket the PROM, swap it between boards, and program it on a standalone Altera programmer before dropping it into the target system. The 65 kb capacity supports full ACEX 1K, FLEX 10K, and early Cyclone bitstreams, allowing one PROM to support many reference designs. The PDIP form factor also simplifies rework and inspection during development. Source: Altera datasheet.
Recommended
Aerospace and Defense Bitstream Storage
Anti-fuse OTP memory is preferred for aerospace and defense applications because it offers high radiation tolerance and tamper resistance. The EPC1064VPC8 stores critical FPGA bitstreams for avionics, guidance, and secure communication systems where reprogramming is undesirable. The DIP package allows easy conformal coating and inspection. Designers should verify radiation and temperature qualifications against their specific program requirements, as commercial-grade OTP parts may not meet all defense specifications. Source: industry application note.
Recommended
Telecommunications Line Card Configuration
Telecommunications line cards based on Altera APEX 20K or FLEX 10KE FPGAs use the EPC1064VPC8 to store the protocol-processing bitstream. The OTP memory ensures the bitstream cannot be modified by network attacks or accidental writes, while the 3.3 V supply aligns with telecom board rails. The serial configuration interface enables fast boot times needed for hot-swap and line-card insertion scenarios. Source: Altera datasheet.
Recommended
Test and Measurement Equipment Firmware Boot
Test and measurement instruments that use FLEX 6000 or ACEX 1K FPGAs for high-speed data acquisition rely on the EPC1064VPC8 to load their DSP and timing logic at boot. The OTP memory guarantees deterministic start-up, and the 65 kb capacity accommodates the bitstreams of these mid-density FPGAs. The through-hole PDIP form factor also simplifies field service and PROM replacement in legacy test equipment. Source: manufacturer datasheet.

Key Differentiators
- Same family, multiple package options for footprint flexibility (vs EPC1064VLC20)
- Anti-fuse OTP vs flash reprogrammability (vs EPCQ-series flash configuration devices)
- Drop-in 8-PDIP family members for legacy board reuse (vs EPC1064PI8 / EPC1064PC8)
Design Notes
Place a 0.1 uF decoupling capacitor as close as possible to the EPC1064VPC8 VCC pin (pin 1). Add a 10 uF bulk capacitor on the same 3.3 V rail to support the inrush current during FPGA configuration. Keep VCC ripple below 50 mVpp; noisy supplies can corrupt the serial configuration data transfer and cause FPGA configuration failures.
Route the nCS, DCLK, DATA, and OE traces between the EPC1064VPC8 and the target FPGA as short, matched-length lines. Keep these traces away from switching power supply nodes and high-frequency clock signals. The serial configuration interface is sensitive to skew; if DCLK exceeds 10 MHz, consider source-series termination to dampen reflections. The 8-pin PDIP allows socket mounting for easy reprogramming during development.
Do not assume any EPC1064VPC8 variant is field-reprogrammable - the device is OTP and once programmed, the bitstream is fixed. Verify that the bitstream size does not exceed 65 kb before committing the PROM; if it does, cascade multiple EPC1-series PROMs or migrate to EPCQ flash. RoHS non-compliance (per distributor data) means the part uses lead-bearing solder; confirm compatibility with your assembly process or seek RoHS-compliant alternatives such as EPCQ devices.
