EPF8820ARC208-3-NW Ringkasan

The Altera (now Intel) EPF8820ARC208-3-NW is a member of the FLEX 8000 family of CMOS programmable logic devices (PLDs), delivering up to 8,000 usable gates, 1,500 registers, and 152 user I/O pins in a 208-pin RQFP (28x28 mm) package with an exposed thermal pad. The device operates from a 4.75 V to 5.25 V single supply and supports system clock frequencies consistent with 5 V FLEX 8000 silicon, making it a drop-in legacy option for industrial and military designs.

A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement any digital logic function. FPGAs sit in the broader taxonomy of programmable logic devices -> complex programmable logic devices (CPLDs) and FPGAs -> programmable logic -> digital IC -> integrated circuit. FLEX 8000 devices occupy the high-density register-rich segment of Altera's classic SRAM-based FPGA portfolio, sitting between early MAX-class CPLDs and later APEX/Cyclone families in both density and process node.

Key features include in-circuit reconfigurability (ICR) via external configuration devices or intelligent controllers, 100% factory-tested logic, multiVolt I/O support in compatible families, and JTAG-based boundary-scan testing. The device offers 4.75V-5.25V core supply tolerance, 152 user I/Os, and a power-optimized architecture that supports sleep mode for low-power standby. The exposed thermal pad on the 208-RQFP package allows PCB ground-plane attachment for improved heat spreading in industrial chassis. The FLEX 8000 architecture uses an SRAM-based look-up table (LUT) fabric with embedded register cells, offering faster place-and-route than CPLDs but requiring configuration at every power-up.

Typical applications include industrial glue logic replacement, telecommunications backplane glue, legacy 5 V bus controllers, prototyping platforms for VHDL/Verilog designs, and digital signal conditioning interfaces. The device is well suited to designs that need high register count and I/O density without migrating to newer 3.3 V / 1.5 V FPGA families, particularly where the 5 V tolerance of FLEX 8000 is required. Design considerations include mandatory external configuration memory (EPC) for SRAM configuration cells, JTAG programming chain design, and careful 5 V power-rail decoupling to support hot-swap or backplane insertion. This page synthesizes distributor pricing, FLEX 8000 family alternatives, and configuration-memory design notes that go beyond the bare datasheet.
