EPF8282AVTC100-4 Ringkasan

The Altera EPF8282AVTC100-4 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), delivering approximately 2,500 usable gates with 208 logic cells in a 100-pin TQFP package. It operates on a 4.75 V to 5.25 V supply, runs at a maximum internal frequency of 125 MHz in the -4 speed grade, and is built on a 0.42 µm CMOS process technology. The device provides 78 user I/O pins, four dedicated inputs, and is configured at system power-up via an industry-standard parallel EPROM, an Altera EPC1/EPC1064/EPC1213/EPC1441 serial configuration device, or a system controller.

What is an FPGA? An FPGA (Field Programmable Gate Array) is a programmable logic device that allows engineers to implement custom digital circuits by configuring an array of logic cells, routing channels, and I/O blocks after manufacture. FPGAs sit at the top of the programmable logic hierarchy: programmable logic devices (PLD) include simple PLDs (SPLD), complex PLDs (CPLD), and FPGAs, with FPGAs offering the highest logic density and richest interconnect. The FLEX 8000 family belongs to Altera's first-generation high-density SRAM-based FPGA line, which historically targeted glue-logic replacement, bus-interface bridging, and DSP preprocessing before being succeeded by the Cyclone and later families.

Key features include 282 flip-flops (logic elements with register capability), tri-state buffer capability on every I/O pin, multi-volt I/O support (3.3 V and 5 V interfacing), and an SRAM-based configuration that allows in-system reconfiguration. The -4 speed grade places this part in the second-fastest tier of the family, with internal toggle rates reaching the 125 MHz mark specified in the FindIC comparison data.

Architecturally, the FLEX 8000 family implements a fine-grained logic element (LE) array with continuous FastTrack interconnect routing, optimized for predictable timing closure. Each LE contains a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade chains, enabling efficient implementation of arithmetic and wide gating functions at moderate logic densities.

Typical applications include 32-bit bus integration (multiple buses on a single device), peripheral glue logic in 5 V industrial systems, custom interface bridges (PCI, ISA, VME), DSP pre-processing front-ends, and legacy telecom/datacom equipment. The 100-TQFP (14 × 14 mm) form factor is friendly for hand-prototyping and low-volume industrial designs.

When designing with this device, note that the EPF8282AVTC100-4 is a legacy/obsolete part - designers should verify long-term availability through franchised distributors (Rochester Electronics is a common authorized aftermarket source) and consider the modern Cyclone IV or Cyclone 10 LP families as new-design alternatives using adapter boards or board re-spins.

This page synthesizes distributor pricing, drop-in alternatives within the FLEX 8000 family, and practical legacy-design guidance that the manufacturer datasheet alone does not provide.
