An FPGA (Field Programmable Gate Array) is a programmable logic device that combines the high integration of a gate array with the design flexibility of in-system programmability. Within the broader integrated circuit taxonomy, FPGAs sit between fixed-function ASICs and lower-density Complex Programmable Logic Devices (CPLDs); FPGAs are preferred when designs require deep combinatorial logic, embedded RAM blocks, and high I/O counts, while CPLDs dominate glue-logic applications. The FLEX 8000 family targets register-rich, system-level integration with in-circuit reconfigurability (ICR).
Key features include 6,000 usable gates (16,000 maximum), 504 logic elements, 12 embedded array blocks (EABs), 118 user I/Os, and 5 V tolerant I/O. Configuration is loaded at system power-up from an industry-standard parallel EPROM or from Altera serial configuration devices (EPC1, EPC1064, EPC1213, EPC1441). High-pin-count PQFP packaging enables integration of multiple 32-bit buses into a single device.
The FLEX 8000 architecture combines a fine-grained Logic Element (LE) fabric with coarse-grained Embedded Array Blocks (EABs) that can implement RAM, ROM, or wide combinatorial functions. CMOS SRAM configuration cells allow unlimited reconfiguration and live in-system upgrades without removing the device from the board.
Typical applications include telecom interface glue logic, industrial control state machines, peripheral bus bridges (PCI, VME, ISA), and legacy 5 V embedded systems. Designers favor this part for 5 V-only boards where modern low-voltage FPGAs are not pin-compatible and a board re-spin is not viable.
When designing with this device, ensure all I/O banks operate within the 5 V VCCIO specification; do not mix 3.3 V peripherals on the same bank. Use the Altera MAX+PLUS II or Quartus (legacy) toolchain for fitting, simulation, and bitstream generation. The 160-pin PQFP footprint requires plated-through-hole or fine-pitch SMD pads; verify your assembly process supports 0.65 mm lead pitch.
This page synthesizes distributor pricing, drop-in alternatives, and design notes that complement the manufacturer datasheet, giving engineers a single source for sourcing and replacement decisions on legacy FLEX 8000 designs.

典型應用
EPF8636AQC160-3N 適用於 6 應用s: Telecom Interface Glue Logic, Industrial Control State Machines, Peripheral Bus Bridges (PCI / VME / ISA), Legacy 5 V Embedded Systems, Test and Measurement Backplanes, Aerospace and Defense Retrofit Programs.
Telecom Interface Glue Logic
The EPF8636AQC160-3N is well suited for telecom interface glue logic where 5 V tolerant I/O and 118 user pins allow direct connection to legacy TTL/CMOS peripherals. The 504 LEs and 12 EABs provide enough capacity to implement UART multiplexing, HDLC framing, and T1/E1 line-interface state machines in a single device. Designers place it between an MPC860 PowerQUICC or similar 5 V communications controller and external PHY devices. The 125 MHz internal FMAX in speed grade -3 comfortably handles 8 Mbps HDLC data paths and 155 Mbps ATM cell-processing glue. Unlike modern 3.3 V FPGAs, no external level shifters are needed on the I/O bank when interfacing to legacy 5 V peripherals.
推薦
Industrial Control State Machines
The EPF8636AQC160-3N suits industrial PLC backplanes and motor-control state machines because of its 0-70 °C commercial operating range, 5 V supply tolerance, and 504 LEs. Engineers implement ladder-logic replacement, PWM generation, encoder decoding, and Modbus / Profibus protocol bridging on a single chip. The 12 EABs can be configured as dual-port RAM to buffer encoder pulse trains or quadrature samples. Its 160-pin PQFP package is well established on through-hole and reflow production lines still used in industrial OEM factories, where 5 V rails are the norm. Compared to a CPLD of similar I/O count, the FLEX 8000 architecture provides several times more sequential logic capacity for multi-axis motion controllers.
推薦
Peripheral Bus Bridges (PCI / VME / ISA)
The EPF8636AQC160-3N is widely used as a 5 V peripheral bus bridge, converting between PCI, VME, ISA, and proprietary 32-bit backplanes. Its 118 user I/Os handle the full 32-bit data bus plus 32-bit address bus with control signals in a single device. The 504 LEs absorb the address-decoding, wait-state generation, and bus-arbiter logic; the 12 EABs implement FIFO buffers for write-posting and read-prefetching. With speed grade -3 supporting 125 MHz internal frequency, the bridge operates comfortably at 33 MHz PCI without wait-state insertion. Compared to discrete 74-series glue logic, the FPGA replaces dozens of SSI/MSI packages and enables late-stage bus-protocol fixes via in-circuit reconfiguration.
推薦
Legacy 5 V Embedded Systems
The EPF8636AQC160-3N is the natural choice for legacy 5 V-only embedded platforms where modern low-voltage FPGAs (Cyclone, Lattice ECP5, Xilinx Spartan-6) are not pin-compatible and cannot operate without level shifters. Common targets include VMEbus single-board computers, CompactPCI carrier cards, and 5 V custom backplanes from the 1990s and early 2000s. The 6K usable gates and 504 LEs deliver ample capacity for custom I/O controllers, interrupt aggregators, and watchdog timers. Because the FLEX 8000 architecture supports in-circuit reconfigurability, firmware updates are possible without removing the board from service - a key advantage in deployed fielded systems where downtime is expensive.
推薦
Test and Measurement Backplanes
The EPF8636AQC160-3N finds application in legacy test and measurement equipment where it implements timing generators, pattern sequencers, and instrument-interface bridges. Its 504 LEs and 12 EABs provide the logic density required for IEEE-488 (GPIB) controllers, VXI register interfaces, and parallel ATE pin-electronics drivers. The 5 V-tolerant 118 I/Os are well matched to the TTL-level pin electronics used in test heads from the late 1990s. Designers appreciate the FLEX 8000 family's deterministic timing model, which simplifies the static timing analysis required for ATE applications. Compared to a discrete TTL implementation, the FPGA reduces board area by 60-70% and simplifies design changes during equipment development.
推薦
Aerospace and Defense Retrofit Programs
The EPF8636AQC160-3N is found in aerospace and defense retrofit programs that extend the service life of fielded avionics, radar signal processors, and naval electronics originally designed with FLEX 8000 logic. Because the part is no longer in production, sourcing through franchised distributors with full traceability documentation is essential for these programs. The 504 LEs and 6K usable gates handle MIL-STD-1553 bus monitors, ARINC 429 interfaces, and radar timing generators. Some retrofit programs have moved to modern plastic-packaged equivalents of the same FLEX 8000 die, preserving the original bitstream and avoiding costly re-verification. The 0-70 °C commercial temperature range is acceptable for many sheltered avionics bays and shipboard equipment enclosures.

主要差異化特點
- Higher logic density than EPF8452AQC160-3 in identical 160-pin PQFP (對比EPF8452AQC160-3)
- Lower-cost commercial speed grade than EPF8636AQC160-4N (對比EPF8636AQC160-4N)
- Standard lead-free 'N' suffix for RoHS-aligned assembly (對比EPF8636AQC160-3)
設計說明
The EPF8636AQC160-3N requires a stable 5 V ±5% supply on both VCCINT and VCCIO pins. Place 0.1 µF ceramic decoupling capacitors as close as possible to every VCCINT and VCCIO pin, with bulk 10-47 µF tantalum or aluminum polymer capacitors at the board entry point. Because the device can draw up to several hundred mA during configuration, ensure the 5 V regulator has adequate headroom and transient response. For multi-FPGA designs, sequence the 5 V rail with the configuration devices to avoid partial-configuration latch-up.
The 160-pin PQFP package uses a 0.65 mm lead pitch, which is at the upper limit for fine-pitch surface-mount assembly. Use a PCB land pattern that follows IPC-7351 guidelines with a footprint pad width of approximately 0.35 mm. Apply a solder paste stencil with 0.15 mm thickness and use no-clean SAC305 lead-free paste for production. For prototyping, consider socketed adapters from manufacturers like Emulation Technology or Ironwood Electronics to avoid damaging expensive FPGAs during rework.
Estimated: configuration bitstream size for a fully utilized EPF8636AQC160-3N is approximately 95-110 Kbits, exceeding the EPC1064 (64 Kbit) capacity. Choose EPC1213 (213 Kbit) or EPC1441 (441 Kbit) for designs using 80-100% of logic resources. Configuring from parallel EPROM at system power-up requires correct nCONFIG, nSTATUS, and CONF_DONE pull-up resistors (typically 10 kΩ to VCC) and proper JTAG chain termination per IEEE 1149.1 (BST). Mixing JTAG and passive serial configuration on the same board requires careful nCE/nCONFIG signal management.
The PQFP-160 package has a typical θJA of approximately 25-30 °C/W in still air, rising with reduced PCB copper area. Estimated: at 5 V VCCINT and 100% logic utilization, the device can dissipate 1.5-2.0 W, producing a junction temperature rise of 40-60 °C above ambient. For enclosed industrial enclosures with ambient up to 60 °C, attach a small clip-on heatsink or use 4-layer PCBs with continuous inner copper planes connected to the thermal pad through vias.
