EPC1213PI8 概述
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.

典型应用
EPC1213PI8 适用于 8 应用s: FLEX 10K Configuration Storage, Stratix FPGA Prototype Boards, Legacy Cyclone Design Re-Spins, APEX 20K Industrial Control Systems, ACEX 1K Educational Lab Kits, Mercury Wireless Base Station Bitstream Backup, Arria GX Config in Test Equipment, Field-Replaceable Configuration Module.
FLEX 10K Configuration Storage
The EPC1213PI8 stores the FLEX 10K configuration bitstream and presents it serially to the FPGA on power-up via nCS/DCLK/DATA. FLEX 10K designs require approximately 80-200 Kbit depending on utilization, all within the EPC1213PI8's 212 Kbit capacity. Used in legacy industrial controllers and telecom line cards that must continue operating without redesign.
推荐
Stratix FPGA Prototype Boards
Designers building Stratix evaluation boards use the EPC1213PI8 to load test bitstreams through the Master Serial configuration chain. The 6 MHz DCLK rate is sufficient for Stratix configuration at default POR delays. The PDIP-8 socket allows quick bitstream swaps during bring-up, eliminating the need to re-program Flash during iteration cycles.
推荐
Legacy Cyclone Design Re-Spins
End-of-life Cyclone and Cyclone II boards are re-spun for continued production using the EPC1213PI8 because the original Altera configuration chain remains intact without PCB rework. The 212 Kbit density accommodates most Cyclone bitstreams (10K to 30K logic elements). Drop-in compatibility with existing Master Serial Mode firmware preserves backward compatibility.
推荐
APEX 20K Industrial Control Systems
APEX 20K designs in factory automation and process control use the EPC1213PI8 to provide non-volatile configuration storage. The industrial -40 C to +85 C operating range supports harsh factory environments. OTP programming eliminates accidental bitstream corruption from EMI events that might otherwise affect in-system programmable Flash devices.
推荐
ACEX 1K Educational Lab Kits
University and training labs use the EPC1213PI8 to load ACEX 1K student designs because the through-hole PDIP-8 package is easily socketed and re-programmed across lab sessions. The simple 4-wire configuration protocol allows students to focus on FPGA logic without learning complex Flash controller interfaces. The 6 MHz clock keeps bitstream load times under 50 ms.
推荐
Mercury Wireless Base Station Bitstream Backup
Mercury (the predecessor to Stratix) wireless base station prototypes store configuration in the EPC1213PI8 as a backup to onboard Flash. The OTP nature guarantees the bitstream cannot be corrupted by software bugs during field updates, providing a known-good recovery image for emergency FPGA re-load via JTAG over the field service port.
推荐
Arria GX Config in Test Equipment
Test and measurement equipment using Arria GX transceivers stores the FPGA bitstream in the EPC1213PI8 to enable rapid board swap in factory calibration lines. The 212 Kbit density covers the smaller Arria GX device variants. Through-hole PDIP assembly simplifies hand-rework when swapping configuration memory between equipment units during calibration.
推荐
Field-Replaceable Configuration Module
End customers upgrade FPGA firmware by physically swapping the EPC1213PI8 chip in its IC socket, eliminating the need for JTAG programmers in the field. Common in industrial controllers, vending machines, and point-of-sale terminals where factory technicians without FPGA tools must perform firmware upgrades. The OTP nature ensures the new bitstream is locked once installed.

设计说明
The EPC1213PI8 is one-time-programmable (OTP). Verify the .pof bitstream file with a test load into a working FPGA before programming the OTP device - a misprogrammed EPC1213PI8 cannot be erased and must be physically replaced. Always use Altera's Quartus II Programmer with verification enabled; never program in-system during production without a known-good reference bitstream stored offline.
Place a 0.1 uF decoupling capacitor as close as possible to the VCC pin (pin 4) of the EPC1213PI8, with trace length under 5 mm to minimize inductance. During FPGA configuration switching transients, the EPC1213PI8 can draw brief inrush currents up to 50 mA. Add a bulk 10 uF tantalum or ceramic capacitor on the VCC rail shared between the PROM and FPGA to prevent supply droop during configuration clock startup.
Route the 4-wire configuration signals (nCS, DCLK, DATA, OE) as a matched-length group with trace impedance controlled to 50 ohm if the FPGA is more than 50 mm away. The DCLK and DATA lines are source-synchronous from the FPGA, so length-matching within 10 mm minimizes setup/hold violations at the 6 MHz configuration clock. Add 33 ohm series damping resistors near the FPGA pins if ringing is observed on the DATA line during readback.
合规信息
