EPF8282ATC100-2 Présentation
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that engineers can configure after manufacturing to implement arbitrary digital logic. The FLEX 8000 family sits in the hierarchy: FPGA → programmable logic device (PLD) → logic IC → integrated circuit → semiconductor. FPGAs differ from CPLDs in their distributed SRAM-based configuration memory, which provides higher logic density and register-rich architectures at the cost of requiring external configuration storage on power-up.
Key features of the EPF8282ATC100-2 include in-circuit reconfigurability (ICR) via the serial configuration interface, JTAG boundary-scan test support, and a multi-volt I/O interface compatible with 5 V and 3.3 V signalling. The device integrates 282 flip-flops distributed across 26 LABs, supporting registered state machines, counters, and datapath logic. The MAX+PLUS II development system provides VHDL, Verilog HDL, and waveform design entry, synthesis, simulation, and timing analysis for the FLEX 8000 family.
The FLEX 8000 architecture is built on a continuous, hierarchical routing fabric with FastTrack interconnect lines spanning the entire device. Each LAB contains 8 logic elements (LEs) with a 4-input look-up table (LUT), programmable register, and carry-chain for arithmetic operations. Dedicated input pins and clock networks support synchronous design patterns common in bus interfacing, peripheral control, and telecommunications glue logic.
Typical applications include bus-interface bridging (PCI, ISA, VME), peripheral controllers, telecommunications line-card glue logic, industrial control state machines, and legacy system upgrades where ASIC-equivalent functionality is needed without the NRE cost. The 100-TQFP footprint makes the EPF8282ATC100-2 compatible with through-hole and surface-mount assembly lines that have been validated for the FLEX 8000 family.
Designers should verify timing closure with MAX+PLUS II timing analysis and budget sufficient I/O headroom for 5 V tolerance on legacy buses. Because the FLEX 8000 family has been in production for decades, second-source supply remains available from authorized distributors and stocking partners.
This page synthesizes distributor pricing, drop-in alternatives from the Site MPN list, and practical design considerations not consolidated on the manufacturer datasheet, helping engineers source pin-compatible replacements for legacy FLEX 8000 designs.

Notes de conception
The EPF8282ATC100-2 requires a clean 5 V supply with adequate decoupling. Per the FLEX 8000 datasheet, place 0.1 µF ceramic bypass capacitors within 5 mm of every VCC pin and provide bulk decoupling (10-47 µF tantalum or ceramic) on the power plane. Estimated ICC (active, all I/Os switching) is approximately 50-100 mA depending on utilization and clock rate; designers should budget 500 mA peak from the 5 V regulator with 20% margin. During configuration download, ICC may spike briefly to 200 mA - the regulator must maintain regulation under this transient load.
The FLEX 8000 family uses SRAM-based configuration memory that is volatile - the bitstream must be reloaded from an external configuration PROM (typically EPC1 or EPC2) on every power-up. Designers frequently forget that JTAG programming does not persist across power cycles without an attached configuration device. For production systems, always include a configuration PROM in the BOM. Additionally, the 5 V I/O tolerance is absolute maximum 5.5 V; operation above this threshold damages the I/O cells. Designers migrating from 5 V to 3.3 V logic must verify signal-level compatibility before connecting mixed-voltage buses.
The 100-pin TQFP package has a thermal resistance θJA of approximately 50 °C/W in still air, rising to 35 °C/W with 100 LFM airflow. Estimated: at 50 mA ICC and 5 V supply, quiescent power dissipation is 0.25 W, yielding a junction temperature rise of 12.5 °C above ambient - well within the 0-70 °C commercial range. However, designers driving 78 I/Os at high toggle rates should add 0.5-1.0 W to the dissipation budget for IO switching losses. For enclosed systems, verify junction temperature with the manufacturer's thermal model before finalizing the mechanical design.
