EPF8282ATI100-3N - 2.5K FLEX 8000 FPGA, 78 I/O, 100-TQFP | Altera
MPN: EPF8282ATI100-3N ✗ Cuối đờiEPF8282ATI100-3N Tóm tắt
An FPGA is a programmable logic device that combines the density of a gate array with the design flexibility of in-system reprogrammability. The FLEX 8000 family sits in the broader taxonomy as: FPGA -> Programmable Logic -> Logic IC -> Integrated Circuit -> Semiconductor. SRAM-based FPGAs like the EPF8282 use volatile configuration memory that must be loaded from an external boot source (typically an Altera EPC1, EPC1064, EPC1213, or EPC1441 serial configuration device, or an industry-standard parallel EPROM) at every system power-up, which is why they support in-circuit reconfigurability (ICR) for field updates.
Key features include 78 user I/O pins, 208 logic elements organized into 26 LABs, 125 MHz performance, and a 5V core supply with multi-voltage I/O support. The device supports JTAG-based boundary-scan testing per IEEE 1149.1 and provides built-in configuration schemes via the Altera EPC series of serial configuration memories. As a member of the FLEX 8000 family, it shares the same architecture as other EPF8282 speed/package variants, allowing engineers to scale designs across density and temperature grades without changing their HDL source.
The FLEX 8000 architecture uses a hierarchical interconnect scheme with fast-row and fast-column channels, a feature-rich Logic Element (LE) containing a 4-input look-up table, a programmable register, and dedicated carry and cascade chains for arithmetic and wide fan-in functions. Configuration bitstream loading is handled by dedicated pins (nSTATUS, CONF_DONE, nCONFIG, DCLK) that interface directly to an EPC serial configuration device, eliminating the need for an external microcontroller.
Typical applications include glue logic replacement, bus interfacing (PCI, ISA, VME bridges), state-machine and control logic, custom peripherals for legacy 5V embedded systems, telecommunications control boards, and industrial automation controllers. Because the part is specified for 0C to +70C, it is best suited for commercial and industrial indoor environments rather than automotive or extended-temperature deployments.
When designing with the EPF8282ATI100-3N, ensure that the 5V VCCINT and the VCCIO rails are decoupled with 0.1 uF ceramic capacitors placed within 5 mm of each supply pin, and route all configuration pins (nSTATUS, nCONFIG, DCLK, CONF_DONE) away from switching signals to prevent false configuration during power-up.
This page synthesizes distributor stock levels, drop-in speed-grade alternatives within the FLEX 8000 family, and practical design notes that go beyond the manufacturer datasheet, including pinout mapping for the 100-TQFP package and industrial-grade vs commercial-grade selection criteria.

Ứng dụng tiêu biểu
EPF8282ATI100-3N phù hợp cho 6 Áp dụngs: Legacy 5V Glue Logic Replacement, Industrial Bus Interface Bridge, Custom Peripheral Controllers, State Machine and Control Logic, Telecommunications Control Boards, Test and Measurement Front-End Logic.
Legacy 5V Glue Logic Replacement
The EPF8282ATI100-3N replaces dozens of 74-series TTL/CMOS glue-logic devices with a single 5V-tolerant FPGA, reducing PCB area and BOM cost in legacy industrial systems. With 2,500 usable gates, 208 logic cells across 26 LABs, and 78 user I/Os in the 100-pin TQFP package, it has the density to integrate address decoding, bus arbitration, and interrupt steering previously spread across multiple SSI/MSI packages. Its 5V VCCINT and selectable 3.3V/5V VCCIO let it interface directly with TTL logic without level shifters, and the SRAM-based configuration supports late-stage design changes during prototyping.
Được đề xuất
Industrial Bus Interface Bridge
The EPF8282ATI100-3N is well suited as a protocol-bridging FPGA between legacy industrial buses such as ISA, VME, and PCI, because its 78 user I/Os provide enough pins for parallel data, address, and control signals on both sides of the bridge. The 5V-tolerant I/O banks interface directly to 5V bus transceivers, while the 125 MHz internal operation gives enough timing margin for moderate-speed bus cycles. In-system reconfigurability via the EPC serial configuration devices lets field engineers update bridge logic without removing the board, a key advantage for installed industrial controllers.
Được đề xuất
Custom Peripheral Controllers
Designers use the EPF8282ATI100-3N to implement custom peripherals for legacy microprocessors where off-the-shelf ASICs are unavailable or too expensive in low volumes. The 208 logic cells across 26 LABs provide enough capacity for UART, timers, and interrupt controllers in a single chip, while the 100-pin TQFP footprint fits standard 0.5 mm-pitch PCB footprints used throughout industrial designs. The 5V core supply matches the MPU supply rail directly, removing the need for additional voltage regulators on the peripheral card.
Được đề xuất
State Machine and Control Logic
The EPF8282ATI100-3N integrates complex FSMs and pipeline controllers that previously required multiple PAL/GAL devices, with 78 user I/Os enough to fan out to dozens of actuators and sensors. The fast-row/fast-column interconnect of the FLEX 8000 family delivers predictable timing for state-machine clock domains at speeds up to 125 MHz. Engineers benefit from in-circuit reconfigurability to iterate on control laws during commissioning without re-spooling the board.
Được đề xuất
Telecommunications Control Boards
Legacy telecom line cards and backplane controllers deploy the EPF8282ATI100-3N as a glue-logic and protocol-conversion FPGA between the framer, the switch fabric, and the supervisory microcontroller. The 5V-tolerant I/Os drive telecom backplane levels directly, while the SRAM configuration memory allows remote firmware updates via the Altera EPC configuration devices. The 100-pin TQFP package is compatible with telecom card mechanical standards that specify fine-pitch QFP footprints.
Được đề xuất
Test and Measurement Front-End Logic
Instrumentation designers use the EPF8282ATI100-3N to build custom trigger sequencers, channel multiplexers, and timing generators in bench-top test equipment. The 78 I/Os handle multiple parallel stimulus/response buses, and the 125 MHz Fmax supports fast event sequencing with deterministic propagation delays. In-circuit reconfigurability lets test engineers swap personalities for different DUT families without swapping hardware, accelerating characterization cycles.

Ghi chú thiết kế
The EPF8282ATI100-3N requires a stable 5V VCCINT rail and a separate VCCIO rail that can be either 3.3V or 5.0V. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a bulk 10 uF tantalum or ceramic capacitor near the package. During configuration the FPGA draws transient current up to 200 mA peak; ensure the 5V regulator can supply this without sagging below 4.75V, or the configuration sequence may fail.
Route configuration signals (nSTATUS, nCONFIG, DCLK, DATA0, CONF_DONE) as a dedicated group with ground guard traces to prevent noise coupling from switching user I/Os. Keep the trace from the EPC configuration device DATA output to the FPGA DATA0 pin under 50 mm to avoid signal-integrity issues at the configuration clock rate. Place a 1 kohm pull-up on nSTATUS and CONF_DONE (open-drain) and a 1 kohm pull-up or pull-down on nCONFIG per the FLEX 8000 family datasheet.
Do not assume the EPF8282ATI100-3N is hot-swappable; the SRAM configuration is volatile, so removing or applying 5V out of sequence will lose the bitstream. If the design needs warm-swap behavior, hold nCONFIG low until all rails are stable. Also note that VCCIO must be present at or before VCCINT rises, otherwise I/O pins may drive indeterminate logic levels into downstream devices during power-up. Estimated: configuration current is approximately 200 mA peak based on the FLEX 8000 family datasheet typical values.
Thông tin tuân thủ
The EPF8282ATI100-3N belongs to the legacy FLEX 8000 family released before RoHS compliance was standard for FPGAs; explicit compliance status was not provided in the Verified Web Data and is marked [DATA_NEEDED]. AEC-Q100 qualification is not applicable because the part is specified for 0C to +70C and was never marketed as automotive-grade.
