EPF8636AQC160-4 - FLEX 8000 FPGA, 6K Gates, 160-PQFP | Intel
MPN: EPF8636AQC160-4 ✗ Cuối đờiEPF8636AQC160-4 Tóm tắt
What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor device whose logic and interconnections are configured by the user after manufacture through SRAM look-up tables, routing matrices, and configurable logic blocks. FPGAs occupy the same hierarchical slot as programmable logic devices (PLDs) and complex PLDs (CPLDs) but offer far higher gate density, putting them above CPLDs and below mask-programmed ASICs in the programmable logic taxonomy.
Key features of the EPF8636AQC160-4 include 63 Logic Array Blocks (LABs), 118 user I/O pins, and 5 V core / I/O supply operation. The "-4" speed grade denotes the slowest of the FLEX 8000 commercial speed bins, trading frequency for lower cost. The device supports MultiVolt I/O, allowing 3.3 V and 5.0 V interface voltages on the same die, which simplified mixed-voltage board designs in the late 1990s and early 2000s.
Architecturally, the FLEX 8000 family uses a continuous FastTrack interconnect routing fabric that delivers predictable, low-skew connections across the device, paired with embedded memory bits and look-up-table based logic elements. Configuration is loaded at power-up from a serial EPROM such as the EPC1, EPC1064, EPC1213, or EPC1441, or from a microprocessor or system controller.
Typical applications include industrial control glue logic, telecom backplane bus bridges, peripheral interface adapters, and legacy equipment retrofits where the design was originally captured against FLEX 8000 silicon. The wide 118-I/O count also supports parallel data-acquisition front ends and 32-bit processor co-processing in cost-sensitive platforms.
A critical design consideration is end-of-life status: FLEX 8000 devices are no longer recommended for new designs. Engineers should plan migration paths to Cyclone-series FPGAs or to MAX-series CPLDs when equivalent logic capacity is sufficient. Existing boards should expect distributor-only inventory and rising unit prices.
This page synthesizes distributor pricing, parametric comparison data, and practical design notes that are not consolidated in the original datasheet, supporting both procurement and engineering review for legacy boards still relying on FLEX 8000 silicon.

Ứng dụng tiêu biểu
EPF8636AQC160-4 phù hợp cho 6 Áp dụngs: Legacy Industrial Glue Logic, Telecom Backplane Bus Bridge, Peripheral Interface Adapter, Data Acquisition Front End, 32-bit Processor Co-Processor, Legacy Equipment Retrofit.
Legacy Industrial Glue Logic
The EPF8636AQC160-4 fits legacy industrial glue-logic applications because its 6,000 usable gates, 504 logic elements, and 118 user I/Os provide ample capacity for bus-bridge, address-decode, and state-machine functions common in PLC backplanes and motor-control boards. With 125 MHz maximum toggle frequency and a 5 V core, it interfaces directly to legacy 5 V peripheral ICs without level shifters, simplifying board design. The MultiVolt I/O feature also lets one device bridge to 3.3 V processors where modern controllers have been retrofitted into older equipment.
Được đề xuất
Telecom Backplane Bus Bridge
The EPF8636AQC160-4 is well-suited as a telecom backplane bus bridge because its 118 user I/Os support wide parallel buses, and its 5 V tolerant MultiVolt I/O pins can interface to both legacy 5 V bus transceivers and 3.3 V control logic. The 504 logic elements provide enough capacity for protocol conversion between E1/T1 framers, HDLC controllers, and processor-side DMA engines, while 125 MHz toggle frequency accommodates standard telecom line rates plus overhead. The 160-pin PQFP package keeps the part on conventional SMT assembly lines used in telecom hardware.
Được đề xuất
Peripheral Interface Adapter
As a peripheral interface adapter, the EPF8636AQC160-4 benefits from its 118 I/O count, which supports a wide range of legacy peripherals (ISA, SCSI, parallel ports, GPIB) on a single device. The SRAM-based architecture allows in-system reconfiguration for firmware updates via JTAG, and the MultiVolt I/O feature enables direct connection to mixed-voltage peripherals without external level translation. Designers can use 504 logic elements to implement state machines, FIFOs, and interrupt controllers in a single chip, replacing multiple 74-series TTL packages.
Được đề xuất
Data Acquisition Front End
The EPF8636AQC160-4 fits data-acquisition front ends because its 118 user I/Os accept parallel output from multi-channel ADCs, and its 504 logic elements implement digital filtering, channel multiplexing, and timing control. With 5 V I/O, it interfaces directly to legacy parallel-output ADCs without level translation, and the 125 MHz toggle frequency supports sample rates above what most 5 V ADCs can deliver. The 160-pin PQFP package provides sufficient I/O count for 16-bit-wide data buses plus dedicated control and clock pins per channel.
Được đề xuất
32-bit Processor Co-Processor
The EPF8636AQC160-4 serves as a 32-bit processor co-processor using its 504 logic elements for custom accelerators, address-decode logic, and external bus arbitration. The 5 V core supply matches legacy 5 V processors and DSPs, while MultiVolt I/O permits direct connection to 3.3 V peripheral buses without external translation. The 118 user I/Os handle 32-bit data plus 24-32 bit address plus control signals, and SRAM-based configuration supports field upgrades via JTAG when co-processor firmware is updated alongside host processor firmware.
Được đề xuất
Legacy Equipment Retrofit
The EPF8636AQC160-4 supports legacy equipment retrofit applications where the original board was designed against FLEX 8000 silicon and replacement parts must remain pin-compatible. Its 160-pin PQFP footprint matches the original PCB land pattern, eliminating the need for board rework during field replacements. The 5 V core and MultiVolt I/O keep compatibility with surrounding legacy analog and digital components, while SRAM-based configuration allows last-minute firmware updates when retrofitting introduces new peripheral behaviors. Distributor-only inventory makes planning essential.

Ghi chú thiết kế
The EPF8636AQC160-4 is obsolete and not recommended for new designs. According to Intel's FLEX 8000 family discontinuance notices, last-time-buy windows have closed and only distributor-channel inventory remains. When designing new boards, select MAX II, MAX V, MAX 10, or Cyclone-series FPGAs instead; for repair or field replacement of legacy equipment, source the original part or one of the listed same-package drop-in alternatives (EPF8636AQC160-3, EPF8636AQC160-4N, EPF8636AQC160-3N).
Estimated: VCCINT (5 V core) typically draws 50-150 mA depending on logic utilization and toggle rate, while VCCIO (3.3 V or 5.0 V I/O) draws an additional 10-50 mA per bank depending on switching frequency and load. Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, plus a 10 µF tantalum bulk capacitor near the device. Each VCCIO bank should have its own 0.1 µF decoupling cap to suppress switching transients on the I/O supply rail.
Do not omit the MSEL0/MSEL1 configuration-mode strap resistors - they select between serial EPROM, parallel EPROM, and microprocessor configuration modes, and floating MSEL pins cause configuration failure. Ensure nSTATUS has a 10 kΩ pull-up to VCCINT and CONF_DONE has a 10 kΩ pull-up to VCCINT per the FLEX 8000 datasheet, otherwise the device will not exit configuration cleanly. For JTAG boundary-scan testing, tie TMS high through a 10 kΩ resistor so the TAP controller enters Test-Logic-Reset at power-up.
Estimated: at maximum toggle rate with all 118 I/Os switching, total power dissipation can reach 0.5-1.0 W; the 160-pin PQFP package has a θJA of approximately 35-45 °C/W in still air, yielding a junction temperature rise of 17-45 °C above ambient. Provide a continuous ground plane on the top and bottom PCB layers under the device for thermal spreading, and place thermal vias under the die-attach pad (if present) to conduct heat to inner copper layers.
Thông tin tuân thủ
The base EPF8636AQC160-4 (without N suffix) is typically a SnPb-finish part per FLEX 8000 era manufacturing; the N-suffix variants (EPF8636AQC160-4N, EPF8636AQC160-3N) provide lead-free RoHS-compliant terminal finish. AEC-Q100 is not applicable because the part is rated for commercial temperature (0 to +70 °C), not automotive.
