EPF8282ATI100-3NGZ 개요
An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs) interconnected by a programmable routing matrix. The FLEX 8000 family belongs to the first-generation SRAM-based programmable logic hierarchy, sitting between simple PLDs and modern high-density FPGAs. After Altera's 2015 acquisition by Intel, the family has been formally classified as mature/obsolete; the manufacturer recommends migration to MAX 10 or Cyclone IV families for new designs.
Key features of the EPF8282ATI100-3NGZ include SRAM-based configuration (allowing in-system re-programmability), 78 general-purpose I/Os, dedicated input registers, fast continuous interconnect (FastTrack), and JTAG-compliant boundary-scan test support per IEEE 1149.1. The device is well suited to glue-logic, bus-interface bridging, and state-machine consolidation tasks that previously required multiple 74-series TTL parts.
From an architectural standpoint, the FLEX 8000 LAB combines 8 logic cells with a local interconnect that feeds the row and column FastTrack routing. Each logic cell contains a 4-input LUT, a programmable flip-flop, and dedicated carry/cascade chains. Configuration bitstream is loaded from an external EPROM or via JTAG, with the device entering user mode once all frames are loaded.
Typical applications include industrial glue logic, legacy peripheral replacement (bus bridges such as ISA-to-local bus), prototyping of medium-complexity state machines, factory automation controllers, and educational FPGA platforms. The 100-pin TQFP footprint also makes the part attractive for hand-soldered prototypes and through-hole-friendly designs where a BGA would be impractical.
When designing with this part, supply decoupling is critical: place 0.1 µF ceramic capacitors on every VCCINT/VCCIO pin and use a bulk 33 µF tantalum near the package. PCB traces carrying high-speed clocks must be length-matched and isolated from switching I/O. Because the FLEX 8000 family is now NRND/obsolete, designers should verify long-term availability before committing to new production.

일반적인 애플리케이션
EPF8282ATI100-3NGZ 적합 용도: 6 애플리케이션s: Industrial Glue Logic Consolidation, Legacy Peripheral / Bus Bridge, Factory Automation State Machine, Educational FPGA Platform, Test & Measurement Fixture, Avionics Legacy Subsystem Sustainment.
Industrial Glue Logic Consolidation
The EPF8282ATI100-3NGZ fits legacy industrial glue-logic consolidation where multiple discrete 74-series TTL/MSI chips can be replaced by a single re-programmable device. With 208 logic cells across 26 LABs and 78 user I/Os, it offers enough capacity to integrate address decoding, bus arbitration, and timing-control functions that previously consumed a square inch of board area. Its 5 V tolerant I/Os interface directly to older industrial buses (ISA, PC/104, VME), eliminating level shifters. The 100-TQFP package supports hand-prototyping for technicians servicing installed equipment, while the SRAM-based configuration allows on-site firmware updates via JTAG without removing the part from the board.
추천
Legacy Peripheral / Bus Bridge
The EPF8282ATI100-3NGZ is well matched to legacy peripheral bridge applications such as ISA-to-local-bus conversion, parallel-port expansion, and 8-bit-to-16-bit bus widening. The 78 I/Os comfortably accommodate two full 8-bit buses plus control signals, and the 125 MHz internal toggle rate allows protocol translation at standard peripheral speeds. The industrial -40 to +85 °C temperature grade ensures reliable operation in factory-floor enclosures without active cooling. Engineers commonly use the JTAG boundary-scan feature to test solder joints on assembled bridge boards, dramatically reducing field return rates.
추천
Factory Automation State Machine
In factory automation controllers, the EPF8282ATI100-3NGZ can replace discrete PLC-like relay ladder logic with a deterministic hardware state machine. Its 26 LABs each containing 8 logic cells provide ample headroom for sequencing conveyor motors, valve actuators, and safety interlocks. The 5 V supply matches legacy industrial backplanes, and the 100-TQFP package can be wave-soldered on standard FR-4 boards used in motor-control cabinets. The SRAM-based architecture enables last-minute logic revisions via JTAG during commissioning, a major advantage over hard-wired relay panels.
추천
Educational FPGA Platform
The EPF8282ATI100-3NGZ, despite being mature, remains a cost-effective learning platform for students studying FPGA fundamentals. The 208 logic cells are sufficient for teaching combinational logic, finite state machines, and basic soft-core processors, while the 100-TQFP package is large enough to be probed by oscilloscope clips without specialized fine-pitch tooling. The Altera/Intel MAX+PLUS II and Quartus II design software still supports the FLEX 8000 family, so students can develop real bitstreams on modern PCs. Breadboarding-friendly 5 V I/Os let beginners interface directly to LEDs, switches, and simple sensors without level translation.
추천
Test & Measurement Fixture
The EPF8282ATI100-3NGZ serves well as the configurable pattern-generation heart of custom test fixtures used in ATE stations and bench-top characterization rigs. Its 78 I/Os can be routed to DUT sockets, while the 125 MHz internal rate supports medium-speed serial protocols like I²C, SPI, and UART emulation. The SRAM configuration allows quick test-pattern changes between device-under-test variants - simply re-load the bitstream over JTAG without removing the FPGA. Industrial temperature rating and 5 V tolerance simplify integration with legacy ATE backplanes that predate low-voltage FPGA generations.
추천
Avionics Legacy Subsystem Sustainment
The EPF8282ATI100-3NGZ continues to play a sustainment role in older avionics LRUs (Line Replaceable Units) where re-engineering is cost-prohibitive but where form-fit-function replacement is required. The 100-TQFP footprint, 5 V supply, and 78 I/Os match the original Avionics Standard design, and the -40 to +85 °C industrial temperature range satisfies cabin-electronics environments. Because the part is obsolete, sustainment programs typically stock pile inventory or use aftermarket brokers; the EPF8282ATI100-3N drop-in is preferred for new LRU builds because of its Pb-free lead finish aligned with modern aerospace environmental regulations.

- Industrial temperature range vs commercial siblings (vs EPF8282ATC100-3)
설계 노트
The EPF8282ATI100-3NGZ requires a clean 5 V core supply on each VCCINT pin (7, 31, 47, 62, 78, 96). Place a 0.1 µF ceramic decoupling capacitor within 5 mm of every VCCINT pin and a single 33 µF tantalum bulk capacitor near the package. The device draws higher inrush current during configuration; ensure the 5 V regulator can supply at least 500 mA peak. Power-rail sequencing must hold the nCONFIG pin low until VCCINT is stable to avoid spurious configuration attempts.
The 100-pin TQFP has a 0.5 mm pitch, which is hand-solderable with fine-tip tools but requires careful paste-stencil design for reflow (150 µm aperture is typical). Use 4-layer PCB stack-up with continuous ground plane under the device to provide low-impedance return paths for the 78 I/Os. Match length on the global clock nets (DCLK, dedicated clock inputs) within 1 mm to avoid skew; place series-termination resistors within 5 mm of the FPGA clock pins.
Do not assume the FLEX 8000 family supports modern 3.3 V LVCMOS I/O standards - the EPF8282A I/Os are 5 V TTL-compatible only. Driving 3.3 V signals directly is fine, but applying 5 V to a downstream 3.3 V device will damage it. Configuration bitstreams must be loaded from an Altera-format .sof or .pof file generated by MAX+PLUS II or Quartus II; older MAX+PLUS II version differences can render bitstreams non-portable. Finally, always verify silicon date codes - pre-2005 production batches may have mask revisions with subtle timing differences.
Because the EPF8282ATI100-3NGZ is now obsolete, design for second-source replacement: leave a footprint compatible with the MAX 10 (10M02SCE144) 144-pin TQFP option for future migration, even if the FLEX 8000 is populated initially. Route JTAG signals (TCK, TMS, TDI, TDO, nSTATUS, nCONFIG, DCLK) to a 2×5 0.1-inch header so the board can be re-programmed in-circuit. Avoid routing sensitive analog signals near the 78 I/O banks to minimize simultaneous-switching noise (SSN) coupling into the 5 V supply.
규정 준수 정보
The -NGZ suffix implies Pb-free lead finish (Altera's -N suffix notation for the FLEX 8000 family). RoHS and REACH compliance status could not be confirmed from the verified distributor data; check the Altera/Intel legacy product page or request a manufacturer certificate of compliance (CoC) for production use. AEC-Q100 qualification is not applicable for industrial-grade FPGAs in this package.
