EPF8282ATC100-2W 概要
An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), programmable interconnect, and configurable I/O cells that the user programs after manufacture. FPGAs sit within the broader hierarchy: programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. Compared to older PLDs such as PALs and GALs, FPGAs offer far higher logic density, register-rich architectures, and SRAM or antifuse configuration memory. The FLEX 8000 family uses SRAM configuration, which means the device must be reloaded at every power-up from an external EPROM or an Altera EPC1/EPC1064/EPC1213/EPC1441 configuration device.
Key features of the EPF8282ATC100-2W include 2,500 typical gates (5,000 maximum), 282 logic elements, 78 user I/Os, 208 flip-flops, 0.5 micron CMOS SRAM process, 5V tolerant I/O, JTAG boundary-scan support, and an industrial-grade speed grade of -2 (the "W" suffix denotes the wider industrial operating-temperature range). The device supports in-system programmability via the IEEE Std 1149.1 (JTAG) interface and can be cascaded with other FLEX 8000 devices for higher-density designs.
The architecture uses four Logic Array Blocks (LABs) per row, with each LAB containing eight Logic Elements (LEs). Each LE consists of a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade paths. FastTrack Interconnect provides continuous routing rows and columns for predictable timing closure.
Typical applications of the EPF8282ATC100-2W include legacy 5V peripheral glue logic, industrial-control state machines, bus-bridging between microprocessor and peripheral buses, prototyping for ASIC emulation, telecom backplane controllers, and military/aerospace systems that still require FLEX 8000 silicon. When designing with this device, ensure a configuration source (EPC1, EPC1064, or parallel EPROM) is present at every power-up, since SRAM cells lose their pattern when VCC drops below the data-retention threshold.

主な用途
EPF8282ATC100-2W の用途: 6 件s: Legacy 5V Peripheral Glue Logic, Industrial Control State Machines, Microprocessor Bus Bridging, ASIC Prototyping and Emulation, Telecom Backplane Controllers, Military and Aerospace Legacy Systems.
Legacy 5V Peripheral Glue Logic
The EPF8282ATC100-2W's 78 user I/Os and 5V-tolerant interface make it well suited for legacy 5V peripheral glue logic. The part integrates 2,500 typical gates, 282 logic elements, and 208 flip-flops, providing enough capacity to replace multiple 22V10 or 16V8 SPLDs while running on the same 5V rail. In a typical application the FPGA sits between a microcontroller bus and 5V peripherals, decoding chip-selects and generating wait-states. Compared to a discrete PLD solution, the FLEX 8000 device offers higher density and JTAG-based in-system reprogrammability, which simplifies board bring-up and field updates.
おすすめ
Industrial Control State Machines
Industrial control designs benefit from the EPF8282ATC100-2W's industrial temperature grade (denoted by the W suffix), 208 flip-flops, and SRAM-based reconfigurability. The FPGA can implement multi-stage FSMs for motor sequencing, valve control, or conveyor logic while surviving harsh factory environments. FastTrack Interconnect provides deterministic timing for safety-critical paths, and JTAG (IEEE 1149.1) boundary-scan enables in-field verification of the FPGA-to-PCB connection. The 100-pin TQFP package also supports hand-rework during prototyping, which is valuable in low-volume industrial automation builds.
おすすめ
Microprocessor Bus Bridging
The EPF8282ATC100-2W is often deployed as a bus bridge between microprocessors and peripherals that use mismatched address or data widths. With 78 user I/Os and 282 logic elements, the device can re-map an 8-bit peripheral bus to a 16-bit or 32-bit processor bus, generate chip-select decoding, and insert wait-states as needed. SRAM configuration lets engineers iterate on the bridge logic in seconds via JTAG, eliminating the long lead times of masked ASIC redesigns. The 100-pin TQFP exposes enough I/O to also handle interrupt glue and DMA handshaking in a single chip.
おすすめ
ASIC Prototyping and Emulation
Designers use the EPF8282ATC100-2W as a fast-turnaround ASIC prototyping platform for low-to-mid complexity ASICs. The 2,500-gate capacity, SRAM configurability, and JTAG-based in-system programming let design teams emulate and verify logic before committing to silicon. Several FLEX 8000 devices can be cascaded on a single JTAG chain to emulate larger ASICs, and the FastTrack Interconnect preserves timing predictability across the chain. The 100-pin TQFP package is convenient for hand-wired prototype boards and FPGA-based emulation rigs used in aerospace and defense verification flows.
おすすめ
Telecom Backplane Controllers
Legacy telecom backplanes rely on the EPF8282ATC100-2W for control-plane glue logic because of its 5V tolerance and high I/O count. The device can implement time-slot assignment logic, address decoding for backplane transceivers, and alarm-monitoring state machines. Industrial-grade temperature operation suits outdoor equipment cabinets, and JTAG boundary-scan supports field diagnostics. The 208 RAM bits and 208 flip-flops are sufficient for small FIFOs and packet-header inspection without needing an external memory device.
おすすめ
Military and Aerospace Legacy Systems
The EPF8282ATC100-2W is specified for industrial temperature operation, which makes it a candidate for legacy military and aerospace systems that were designed around FLEX 8000 silicon and require form-fit-function replacement. Long-life-cycle programs use the W-suffix variant to maintain qualification baselines, and 100-pin TQFP is convenient for through-hole-style rework on ruggedized boards. JTAG boundary-scan is essential for field-programmable bitstream verification on avionics and naval platforms. Designers should verify lot date codes and obtain full traceability documentation when sourcing this obsolete part for safety-critical applications.

設計ノート
The EPF8282ATC100-2W is a SRAM-based FPGA, so it must be reconfigured at every power-up. Always include a configuration source such as the Altera EPC1, EPC1064, EPC1213, or EPC1441, or a standard parallel EPROM. Hold nCONFIG low during power-up ramp until the supply rails stabilize, then drive nCONFIG high to begin configuration. CONF_DONE goes high only after the bitstream has been successfully loaded.
Industrial-grade operation (-40C to +85C ambient for the W suffix) requires adequate thermal relief on the PCB. While FLEX 8000 devices consume less power than modern FPGAs, the 100-pin TQFP package should still be tied to a ground plane with multiple thermal vias to spread heat. For designs that operate continuously at high toggle rates, derate by 10-15 percent above 70C ambient to maintain timing margin.
Place the configuration EPROM (EPC1 or EPC1064) as close as possible to the EPF8282ATC100-2W to minimize trace-induced noise on the configuration data lines. Provide local 0.1 uF decoupling capacitors on every VCC pin and a bulk 10 uF tantalum capacitor near the device. Keep JTAG signals (TMS, TCK, TDI, TDO) short and away from switching signals to preserve in-system programming reliability.
Do not confuse the EPF8282ATC100-2W (industrial) with the EPF8282ATC100-2N (commercial); substituting one for the other will invalidate any qualification baseline. Because the part is obsolete, counterfeit risk is high - source only from authorized distributors and request date-code and lot-traceability documentation. Verify the bitstream CRC at every JTAG chain before relying on field-deployed hardware.
