EPF8820ATC144-2N Ringkasan

The Altera (Intel) EPF8820ATC144-2N is a FLEX 8000 family Field-Programmable Gate Array (FPGA) delivering 8,000 usable gates, 672 logic elements, and 112 user I/Os in a 144-pin Thin Quad Flat Pack (TQFP) package. Built on a 0.42 µm CMOS SRAM process and operating from a 5 V supply, it supports in-circuit reconfigurability through external configuration EPROMs or Altera EPC1/EPC1064/EPC1213/EPC1441 serial configuration devices, enabling system-level flexibility for prototyping and field updates.

A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that an engineer can program to implement arbitrary digital logic, glue logic, bus interfaces, state machines, and signal-processing datapaths. Within the broader taxonomy, FPGAs sit alongside CPLDs in the programmable logic hierarchy and are categorized under Integrated Circuits > FPGA & CPLD. FLEX 8000 was Altera's register-rich, high-density family positioned between simpler Classic EPLDs and the larger FLEX 10K family that introduced embedded array blocks.

Key features of the EPF8820ATC144-2N include 84 logic array blocks (LABs), 112 maximum user I/O pins, and a maximum toggle frequency of 125 MHz. The device supports multi-voltage I/O operation (TTL and CMOS interfaces) and offers fast in-system configuration via the FLEX configuration scheme. The high-pin-count 144-TQFP package integrates multiple 32-bit buses into a single device, allowing dense glue-logic and peripheral-bridge designs.

The EPF8820ATC144-2N uses Altera's classic 4-input look-up table (LUT) architecture with a continuous routing network, providing predictable timing and good register-to-logic ratios suited for state machines, datapath registers, and address decoding. The 5 V core is robust for legacy industrial interfaces and TTL buses.

Typical applications include TTL and bus integration (PCI bridges, ISA glue logic), high-speed controllers, coprocessor functions, DSP preprocessing, wide-data-path manipulation, and address/data translation between mismatched processor peripherals. The 112 I/Os comfortably handle 32-bit datapaths plus control.

When designing with this part, ensure correct configuration mode selection (FLEX configuration scheme), proper decoupling of the 5 V rail, and observance of TQFP-144 PCB land pattern guidelines for reliable hand or reflow soldering.
