EPF8820ATC144-6 Ringkasan

The Altera EPF8820ATC144-6 is a member of the FLEX 8000 programmable logic device family, delivering approximately 8,000 usable gates, 672 logic cells, and 112 user I/Os in a 144-pin TQFP (LFQFP) package. Operating from a 5V supply at a 125MHz internal frequency, this CMOS SRAM-based FPGA provides low-cost, high-density register-rich programmable logic with in-circuit reconfigurability.

A Field Programmable Gate Array (FPGA) is a semiconductor IC built around an array of configurable logic blocks (CLBs), programmable routing channels, and programmable I/O cells. FPGAs sit at the top of the digital logic hierarchy: programmable logic device (PLD) -> complex PLD (CPLD) -> FPGA -> SoC FPGA. The FLEX 8000 family targets glue-logic, bus-interface, and state-machine consolidation roles where discrete 74-series logic or a CPLD would otherwise consume excessive board area.

Key features include 84 Logic Array Blocks (LABs) with 8 logic elements per LAB, 4 dedicated input pins, MultiVolt I/O supporting 3.3V or 5.0V interface (144-pin packages), and configuration via industry-standard parallel EPROM or Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441). The -6 speed grade specifies a worst-case propagation delay of approximately 1.9ns.

The FLEX 8000 architecture uses continuous SRAM configuration memory, allowing in-system reconfiguration (ICR) via a controller or configuration device. Each LAB contains an expansion product-term array and a carry chain for arithmetic functions; interconnect uses FastTrack routing with row and column channels. Die size and process technology make this device the lowest-density FLEX 8000 variant, suitable for designs that exceed CPLD capacity but do not require modern high-logic-count FPGAs.

Typical applications include bus-interface bridging (PCI, ISA, VME), glue-logic consolidation in industrial controllers, state-machine replacement, address decoding and interrupt handling in embedded systems, and legacy 5V peripheral interfacing where MultiVolt I/O removes the need for level shifters. Production-intent designs targeting this part typically migrate to newer Cyclone or MAX families today.

Design considerations include dedicated VCCINT and VCCIO rail separation for 3.3V/5.0V I/O, mandatory configuration device selection (EPC1, EPC2, EPC1441), and JTAG support via nCONFIG, nSTATUS, and CONF_DONE pins. The -6 speed grade represents one of the slower grades in the family; faster -3 or -2 grades are usable when timing margins are tight.
