EPC1PC8CCD Overview
A configuration PROM is a non-volatile memory device that holds the FPGA's programming bitstream and presents it to the target logic device through a serial configuration interface at every power-on or reconfiguration event. The EPC1 family is the second-generation Altera configuration PROM series, replacing earlier EPC1441/EPC1064 devices with higher density, lower power, and improved cascading. The device operates as a peripheral to the FPGA and is part of the broader FPGA configuration and programming hierarchy: configuration PROM -> non-volatile memory -> boot memory -> FPGA.
Key features include 1 Mb (1,048,576 bits) of OTP storage, serial daisy-chain cascading to support multi-FPGA configurations or larger bitstreams, 3.3V core VCC operation, a low-power CMOS process, and a dedicated DATA output clock generated by the internal oscillator for handshaking with the Altera FLEX or APEX configuration controller. The 8-PDIP package provides easy insertion into sockets or through-hole prototyping boards, making the EPC1PC8CCD well suited to early design verification, low-volume production, and educational/development kits.
From an architectural standpoint, the EPC1PC8CCD uses an anti-fuse OTP cell array programmed via the Altera programming hardware, with each bit accessed sequentially during FPGA configuration. The internal address counter increments on each rising edge of the internal configuration clock, and a CONF_DONE handshake with the FPGA ensures the bitstream has been fully delivered before the FPGA enters user mode. The device supports both single-device and multi-device (cascaded) configuration topologies.
Typical applications include configuring Altera FLEX 6000 / FLEX 8000 / FLEX 10K, APEX 20K, and ACEX 1K family SRAM-based FPGAs, prototyping boards and lab development kits, industrial control systems using legacy Altera logic, and legacy board refreshes where the original EPC1PC8 bitstream must remain compatible.
When designing with this device, engineers should note that OTP cells can be programmed only once, so designers must verify the bitstream is final before committing the configuration. The 8-PDIP package is intended for through-hole mounting and is not recommended for high-vibration surface-mount environments; for SMT designs, the equivalent EPC1PC8 in PLCC is preferred.

Typical Applications
EPC1PC8CCD is suitable for 7 applications: Legacy Altera FLEX 10K FPGA Configuration, APEX 20K Family Boot Memory, Industrial Control / Legacy Board Refresh, Development Kit and Educational Boards, Aerospace and Defense Legacy Avionics, Telecommunications Backplane Glue Logic, Test and Measurement Equipment.
Legacy Altera FLEX 10K FPGA Configuration
The EPC1PC8CCD stores the 1-Mbit configuration bitstream for Altera FLEX 10K and FLEX 10KA SRAM-based FPGAs and serially delivers it through the EPC1 interface at every power-up. With a 3.3 V VCC matching the FLEX 10K VCCIO rail and a direct DATA/DCLK handshake to the FPGA, the device eliminates the need for external boot memory. Designers should route DATA and DCLK as short matched traces to the FLEX nCONFIG/nSTATUS pins to avoid setup/hold violations during configuration.
Recommended
APEX 20K Family Boot Memory
The EPC1PC8CCD is sized for single-device configuration of smaller APEX 20K and APEX 20KE FPGAs and supports daisy-chain cascading for larger APEX 20K members such as the EP20K400. The 3.3 V supply and CMOS-low-power operation keep total boot-time current under 50 mA even when cascading up to four devices. Place the EPC1PC8CCD within 25 mm of the FPGA's DATA pin to keep the configuration clock clean.
Recommended
Industrial Control / Legacy Board Refresh
Long-lifecycle industrial controllers and instrumentation built on FLEX 6000 / FLEX 8000 logic require the EPC1PC8CCD as a one-time boot memory when the original configuration PROM has failed or been obsoleted. The 8-PDIP package drops into legacy through-hole sockets without PCB rework, preserving form-fit-function. Commercial 0 C to +70 C operation is adequate for most indoor control cabinets; for outdoor or -40 C sites, designers should verify an industrial-grade equivalent remains available.
Recommended
Development Kit and Educational Boards
The 8-PDIP through-hole package of the EPC1PC8CCD makes it ideal for FPGA development kits, university teaching boards, and breadboard prototypes where the configuration bitstream must be replaced as students iterate designs. Although the OTP nature prevents in-system reprogramming, the low per-unit cost (approximately USD 7.95 at 1000 pieces) supports one PROM per board revision. Pair with an Altera ByteBlasterMV download cable for factory programming.
Recommended
Aerospace and Defense Legacy Avionics
Long-life avionics and defense platforms originally designed around Altera APEX 20K and FLEX 10K FPGAs continue to use the EPC1PC8CCD for field-replaceable configuration storage, because the through-hole DIP package supports socketed module replacement at depot-level maintenance. The OTP behavior is acceptable because the configuration bitstream is revision-controlled and rarely changes. Designers must verify lot traceability and counterfeit-mitigation through the franchised distributor channel.
Recommended
Telecommunications Backplane Glue Logic
Legacy telecom backplanes using ACEX 1K and FLEX 10KE devices for protocol bridging and TDM switching rely on the EPC1PC8CCD for in-system boot configuration. The 3.3 V supply rails align with the -48 V isolated intermediate bus and the 1 Mb storage matches ACEX 1K EP1K10/EP1K30 bitstreams. The cascading support allows up to 8 EPC1 devices in series to boot multiple FPGAs in parallel from a single JTAG chain.
Recommended
Test and Measurement Equipment
Bench-top oscilloscopes, logic analyzers, and protocol testers originally built around FLEX 10K glue logic continue to use the EPC1PC8CCD for stable, one-time boot configuration. The 8-PDIP package accommodates socketed replacement during factory rework, and the 0 C to +70 C commercial range fits climate-controlled lab environments. Counterfeit risk is mitigated by sourcing only through franchised distributors with traceable lot dates.

Key Differentiators
- Lead-free NiPdAu finish for RoHS compliance (vs EPC1PC8 (SnPb))
- Identical die and electricals to EPC1PC8 family (vs EPC1PC8 / EPC1PC8CC)
- Through-hole 8-PDIP for legacy board refresh (vs EPC1PC8 in PLCC package)
Design Notes
Route DATA and DCLK as short, length-matched traces between the EPC1PC8CCD and the target FPGA. A series 33 ohm damping resistor close to the EPC1 DATA output is recommended when the FPGA is more than 50 mm away, to suppress ringing on the configuration clock. Keep the nCONFIG trace separated from noisy switching signals because it is level-sensitive during FPGA configuration handshake.
VPP (pin 8) must be tied to GND during normal read/configuration operation. Applying 12 V to VPP in-circuit during normal operation will damage the device. VPP is only energized by the Altera programming hardware (e.g., ByteBlasterMV with the MasterBlaster / PL-APU programming adapter) during factory programming. Designers should leave a 0.1 uF + 10 uF decoupling capacitor pair on VCC close to pin 6.
The EPC1PC8CCD is OTP - once programmed it cannot be erased or rewritten. Designers must generate the final .pof (programming object file) from Quartus II and verify it on a Cyclone / Stratix reference board before committing the configuration PROM. For iterative development, use the EPCS1/EPCQ16 SPI flash families or a generic M25Pxx SPI flash instead. A factory-programmed EPC1PC8CCD with a bad bitstream is unrecoverable.
Estimated: total VCC current during configuration is approximately 20 mA typical / 40 mA peak, drawn from a 3.3 V rail. A 0.1 uF decoupling capacitor placed within 3 mm of pin 6 plus a 10 uF bulk capacitor on the same node is sufficient to hold ripple below 50 mV during cascade configuration of up to 8 EPC1 devices. The VPP pin draws no current during read mode.
Compliance Information
RoHS compliance inferred from the NiPdAu lead finish designated by the 'D' suffix in the ordering code. Halogen-free status not stated in the verified data and is set to 'unknown'. The part is not AEC-Q100 qualified - it is a commercial-temperature (0C to +70C) configuration PROM intended for digital logic boot, not automotive.
