EPF8820ARC160-2 개요
What is a FLEX 8000 FPGA? FLEX 8000 is a legacy SRAM-based Field-Programmable Gate Array family introduced by Altera (now Intel PSG) in the mid-1990s. Hierarchically, FLEX 8000 sits between simple PLDs/CPLDs (small logic-only devices) and modern high-density SRAM FPGAs (Cyclone, MAX series): device -> FPGA -> programmable logic -> integrated circuit -> semiconductor. FPGAs contain configurable logic blocks (here, 4-LUT-based LEs grouped into LABs), programmable routing, and I/O cells; SRAM configuration makes them in-system reprogrammable but requires a configuration memory on every power-up.
Key features include 120 user I/O pins supporting 5 V TTL/CMOS interfaces, on-chip SRAM-based configuration memory, multi-volt I/O compatibility, JTAG (IEEE 1149.1) boundary-scan test support, and a 4-input Look-Up Table (LUT) logic architecture. The part is built on a 0.5 µm CMOS SRAM process (Altera FLEX 8000 family), giving it non-volatile operation only when paired with an external configuration EPROM such as the EPC1 or EPC2.
The device targets applications like industrial control glue logic, telecom line-card interface bridging, PCI bus interface bridging, custom peripherals for embedded microprocessors, and legacy replacement of 74-series and 4000-series MSI/LSI logic. With 120 I/O it can sink/source up to 25 mA per pin (typical) and supports PCI-compliant drive.
When designing with EPF8820ARC160-2, plan for configuration: a serial configuration EPROM (EPC1/EPC2) or microcontroller must load the SRAM at every power-up. The 160-BQFP package has a footprint roughly 28 mm × 28 mm; provide four-layer PCB with solid ground and power planes for noise-sensitive applications.

일반적인 애플리케이션
EPF8820ARC160-2 적합 용도: 6 애플리케이션s: Legacy Industrial Glue Logic, PCI Bus Bridge / Interface Bridging, Telecom Line-Card Interface Logic, Embedded Microcontroller Peripheral Expansion, Custom State Machines and Protocol Controllers, Legacy Replacement and Field Repair.
Legacy Industrial Glue Logic
The EPF8820ARC160-2 fits legacy industrial glue-logic applications that previously required dozens of 74-series MSI parts. Its 672 logic elements deliver roughly 8,000 usable gates, enough to integrate address decoding, bus arbitration, custom state machines, and interrupt controllers on a single 5 V device. With 120 user I/O, the part can replace a full board of discrete logic while running from the same 5 V supply as the surrounding TTL/CMOS circuitry. Engineers use the FLEX 8000 architecture to retain in-system reprogrammability during system bring-up, allowing last-minute logic fixes without board respins.
추천
PCI Bus Bridge / Interface Bridging
The EPF8820ARC160-2 is widely used as a PCI bus bridge or interface bridging device between microprocessors, DSPs, and legacy peripherals. Its 120 user I/O pins can carry an entire 32-bit PCI bus (32 data/address + 8 control) plus ancillary control lines, and the 4-input LUT + carry-chain architecture synthesizes 32-bit counters, FIFOs, and address-decoding logic efficiently. The 5 V TTL I/O is PCI-compliant when the device is configured in PCI mode. Designers appreciate the in-system SRAM programmability for fixing protocol bugs in the field without respinning the host board.
추천
Telecom Line-Card Interface Logic
Telecom line-card and central-office designs adopted the FLEX 8000 family for custom interface and framing logic. The EPF8820ARC160-2 with 672 LEs and 120 I/O implements HDLC controllers, framing bit-processors, T1/E1 line-interface glue, and custom serial-to-parallel converters on a single device. Its commercial 0 °C to 70 °C range suits environmentally controlled CO bays. The 160-BQFP package's large thermal copper pad area also helps dissipate heat in enclosed, fan-less line-card assemblies. JTAG boundary-scan eases in-system test of the dense BQFP footprint.
추천
Embedded Microcontroller Peripheral Expansion
Embedded designs using 8-bit and 16-bit microcontrollers (8051, 68xxx, MIPS, x86) often lack I/O or peripheral features, and the EPF8820ARC160-2 serves as a configurable peripheral-expansion companion. With 120 I/O it adds parallel ports, PWM generators, quadrature decoders, or custom serial interfaces (UART, SPI, I2C master/slave) next to a host MCU that has run out of pins. The 5 V supply matches legacy MCU rails, and in-system SRAM programmability allows firmware engineers to update peripheral behavior alongside MCU firmware revisions.
추천
Custom State Machines and Protocol Controllers
The EPF8820ARC160-2 is a natural fit for complex state-machine and protocol-controller implementations where discrete 74LS/74AS state machines would consume too much board area. With 672 4-input LUT-based logic elements, the device can implement multi-state machines with hundreds of states, packet-framing logic, custom synchronous protocols, and proprietary bus controllers. Engineers benefit from FPGA design tools that synthesize state machines directly from HDL descriptions, and the in-system reprogrammability allows rapid protocol iteration during OEM development.
추천
Legacy Replacement and Field Repair
Many long-lifecycle industrial, military, and avionics systems still contain EPF8820ARC160-2 devices that must be repaired for decades. The part supports legacy replacement and field-repair workflows by enabling direct PCB-level swaps on existing 160-BQFP land patterns. Distributors Ocean-Components, Wolfchip, and Micro-Semiconductor report thousands of remaining new-old-stock pieces, which feeds the aftermarket repair pipeline. The 5 V supply, JTAG test, and known-good bitstream ensure repaired systems retain original functionality without requalification.

설계 노트
The EPF8820ARC160-2 requires a clean 5 V supply (4.75 V to 5.25 V) on VCCINT pins, plus separate VCCIO1/VCCIO2/VCCIO3/VCCIO4 rails for each of the four I/O banks. Estimated: a fully utilized EPF8820 with all 120 I/O toggling at 50 MHz draws roughly 200-300 mA on VCCINT plus I/O supply current proportional to loading. Decouple each VCC/VCCIO pin with a 0.1 µF ceramic and place a bulk 47 µF tantalum near the device. Configuration EPROM supply must ramp within Intel-specified tRSTL/VCC timing to avoid configuration failure.
The 160-BQFP (Metric Quad Flat Pack) has a 0.65 mm pitch and ~28 mm body. Provide 4-layer PCB with solid ground and power planes directly under the device for VCCINT/GND return paths. Keep configuration EPROM (EPC1/EPC2) within 50 mm to minimize passive-serial trace length. Use 0.1 µF decoupling within 5 mm of each VCC pin. JTAG chain should have a 10 kΩ pull-up on TCK/TMS/TDI to keep the boundary-scan state valid at power-up.
Common pitfalls with EPF8820ARC160-2 designs: (1) forgetting that configuration SRAM is volatile - the device WILL NOT retain its design without an external EPC1/EPC2 EPROM or MCU passive-serial master; (2) mixing 160-BQFP metric) and 160-PQFP (JEDEC) land patterns - they are NOT identical; (3) ignoring the speed-grade downgrades: replacing -4 with -2 reduces timing margin; (4) leaving JTAG chain unterminated can lock the device into a non-functional state during power-up; (5) using 3.3 V signals on a 5 V VCCIO bank without level translation violates Absolute Maximum Ratings.
