EPF8820AGC192-2 - FLEX 8000 FPGA, 8K Gates, 192-Pin CPGA | Intel
MPN: EPF8820AGC192-2 ✗ Cuối đờiEPF8820AGC192-2 Tóm tắt
An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be electrically reconfigured by the designer after manufacture. FPGAs sit within the broader hierarchy: programmable logic device (PLD) -> FPGA -> programmable logic -> digital semiconductor. The FLEX 8000 family, introduced in the mid-1990s, was one of the early register-rich, SRAM-based CMOS PLD families aimed at glue-logic, bus-interface, and state-machine consolidation in 5 V systems.
Key features include a maximum clock frequency of 125 MHz, propagation delay of 5.0 ns (per third-party catalog data), 3.3 V or 5 V tolerant I/O operation, and configurable I/O standards. The device supports multiple I/O voltage references, allowing direct interfacing with 3.3 V and 5 V buses. In-circuit reconfigurability lets the design be updated in-system without removing the part, which was a defining advantage of the FLEX 8000 family over one-time-programmable PLDs.
Architecturally, the EPF8820AGC192-2 uses a SRAM-based lookup-table fabric backed by registers, with FastTrack interconnect providing predictable routing delays. The 192-pin CPGA ceramic package is intended for through-hole industrial and military sockets where mechanical robustness and thermal performance outweigh the board area required by plastic QFP alternatives.
Typical applications include industrial bus controllers, legacy 5 V system glue logic, telecom backplane interface logic, prototyping platforms, and retrocomputing or avionics systems where FLEX 8000 designs are preserved as firmware-equivalent IP. The 5 V tolerant I/O simplifies integration with TTL and CMOS legacy buses.
When designing with this part, ensure the configuration EPROM is correctly selected and that ICR is disabled during reset to prevent spurious configuration loading. The CPGA package requires a through-hole socket; verify socket footprint and pin-1 orientation before layout.

Ứng dụng tiêu biểu
EPF8820AGC192-2 phù hợp cho 6 Áp dụngs: Legacy 5 V Industrial Glue Logic, Telecom Backplane Interface Logic, Military and Avionics Retrocomputing, Prototyping Platform FPGA, Firmware-Equivalent IP Preservation, Bus Protocol Bridge and State Machine Controller.
Legacy 5 V Industrial Glue Logic
The EPF8820AGC192-2 is purpose-built for legacy 5 V industrial systems where modern sub-3.3 V FPGAs cannot directly interface with TTL buses. Its 5 V VCCINT supply and 3.3 V/5 V tolerant I/O eliminate the need for level-shifters when bridging to 5 V microcontrollers, optocouplers, and bus transceivers. With 8K usable gates and 672 logic cells, the part consolidates multiple 74-series glue-logic ICs onto one programmable device, reducing PCB area and BOM count in PLC backplanes, motor-control boards, and process-control instruments. The 192-pin CPGA package withstands industrial vibration and thermal-cycling environments better than plastic QFP, making it a fit for factory-floor controllers expected to operate for 15+ years.
Được đề xuất
Telecom Backplane Interface Logic
The EPF8820AGC192-2 historically served telecom backplane designs as a programmable bus-interface controller, framing unit, or HDLC channel handler. Its 125 MHz internal clock and 1,500 registers provide the throughput needed for T1/E1 aggregation, while the 192-pin CPGA package enables high I/O count for parallel backplane buses. The in-circuit reconfigurability allowed field upgrades without board swap - critical for telecom central-office equipment where downtime is measured in revenue loss per minute. Modern systems have largely migrated to Cyclone IV/10 devices, but the EPF8820AGC192-2 remains in service in deployed equipment where the design IP is locked to the FLEX 8000 architecture and 5 V backplane signaling.
Được đề xuất
Military and Avionics Retrocomputing
The 192-pin ceramic CPGA package qualifies the EPF8820AGC192-2 for military and avionics retrocomputing platforms where plastic-encapsulated parts are unacceptable for hermeticity and outgassing reasons. The part supports legacy MIL-STD-1553, ARINC 429, and discrete-signal interface cards on legacy aircraft, naval systems, and ground vehicles. With 8K gates and 1,500 registers, it implements bus monitors, discrete I/O concentrators, and protocol bridges on cards designed in the 1990s-2000s. Long-term supportability depends on diminishing factory stocks and authorized aftermarket distributors; form-fit-function replacement requires part-number identity or verified drop-in equivalents, neither of which exist in the open market as of 2026-09-12.
Được đề xuất
Prototyping Platform FPGA
Universities, research labs, and retrocomputing hobbyists use the EPF8820AGC192-2 as a teaching and prototyping platform for FLEX 8000-era design flows, including the original Altera MAX+PLUS II and Quartus II development environments. The 192-pin CPGA socket allows the part to be swapped between projects, and the in-circuit reconfigurability supports rapid iteration. While modern Cyclone or Artix boards offer more logic density at lower cost, the EPF8820AGC192-2 retains pedagogical value for studying 5 V CMOS PLD architecture, SRAM-based configuration, and legacy EDA toolchains. Its through-hole package also makes it accessible for solder-less breadboard prototyping where fine-pitch BGAs cannot be used.

Firmware-Equivalent IP Preservation
Many equipment manufacturers ship products with FLEX 8000 bitstreams that have been certified, validated, or otherwise locked by regulatory bodies (FDA, FAA, NRC). When the original FPGA is end-of-life, the only path to preserve the certification is to source the exact same die and package. The EPF8820AGC192-2 is the canonical part for these designs, and even when the silicon is re-marked or pulled, regulators accept the substitution if the part number matches. This drives continued procurement of the EPF8820AGC192-2 long after Altera/Intel discontinued the family, despite the 41 percent counterfeit risk noted in open-market distributor intelligence.

Bus Protocol Bridge and State Machine Controller
The EPF8820AGC192-2 is well-suited to bus-protocol bridging between legacy and modern interfaces - for example, ISA-to-PCI bridges, VMEbus arbiters, or serial-to-parallel protocol converters. Its 672 logic cells implement deep state machines with 1,500 registers, and the 5 V I/O tolerance interfaces directly to TTL peripheral chips. The 192-pin CPGA package provides ample I/O count (typically 150+ user I/O pins) for parallel bus implementations. Designers use the FLEX 8000 family to consolidate scattered 74LS glue logic, PALs, and GALs onto a single reprogrammable device, simplifying board layout and enabling late-stage design changes via in-circuit reconfiguration.

Ghi chú thiết kế
Counterfeit risk is significant: per GlobalSpec distributor intelligence as of 2026-09-12, the EPF8820AGC192-2 has a 41 percent counterfeit threat in the open market. Always procure from authorized distributors or independent sources that provide traceability, date-code, and lot documentation. Re-marked pulls from the 1990s-2000s are common; X-ray and decapsulation inspection may be required for high-reliability applications.
The 192-pin CPGA package requires a through-hole PGA socket (e.g., 3M Textool or equivalent). Verify the socket pin numbering matches the FLEX 8000 datasheet pin table before PCB layout. The CPGA ceramic package is heavier than plastic equivalents - use mechanical support standoffs if the board is subject to vibration or shock (e.g., MIL-STD-810 environments).
FLEX 8000 I/O are 3.3 V/5 V tolerant but the VCCINT core is 5 V only. Do not interface 1.8 V or 2.5 V signals directly without level shifters. For multi-voltage buses, use external transceivers (e.g., 74LVTH245 for 3.3 V, 74HCT245 for 5 V TTL). Decouple VCCINT with 0.1 µF ceramic + 10 µF tantalum per supply pin per the FLEX 8000 datasheet decoupling recommendations.
