EPF8636AQC160-4N Обзор
An FPGA (Field Programmable Gate Array) is a reprogrammable digital IC whose logic and interconnects are configured by static RAM cells. FPGAs sit within the broader programmable logic hierarchy (PLD → CPLD → FPGA) and are commonly classed as a sub-category of digital ASICs/structured ASICs. They are used wherever a custom digital function must be implemented quickly and updated without respinning silicon, and FLEX 8000 was Altera's first-generation high-density FPGA family introduced in the mid-1990s, later folded into the Intel FPGA portfolio after the 2015 Altera acquisition.
Key features of the EPF8636AQC160-4N include 504 logic elements, 118 user I/Os, embedded JTAG boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1-1990 on selected devices, peripheral registers for fast setup and clock-to-output delay, full PCI Local Bus Specification compliance, and 5 V / 3.3 V I/O compatibility. Maximum toggle performance is approximately 125 MHz internally, with Fmax typically reported near 83 MHz for register-rich designs.
Architecturally, FLEX 8000 devices use continuous, SRAM-based lookup-table (LUT) logic elements arranged in Logic Array Blocks (LABs), interconnected by FastTrack continuous routing. Configuration data is loaded at power-up from an industry-standard parallel EPROM, an Altera serial configuration device, or a system controller, giving true in-circuit reconfigurability (ICR).
Typical applications include PCI bus interface bridges, peripheral glue logic in industrial controllers, legacy telecom backplane controllers, and JTAG-driven prototype boards. The 160-pin PQFP footprint and 5 V I/O make it a drop-in option for legacy designs that still require a high-density 5 V FPGA rather than a modern 3.3 V or 1.8 V device.
When designing with this device, ensure the configuration EPROM is sized for the compressed bitstream, observe 5 V VCCIO ramp sequencing, and use Altera MAX+PLUS II or Quartus for synthesis. JTAG BST pins must be reserved if boundary-scan testing is required.
This page synthesizes distributor pricing, drop-in alternatives within the FLEX 8000 family, and practical design notes not found in the original datasheet, giving engineers a single reference for sourcing and migrating legacy designs.

Типичное применение
EPF8636AQC160-4N подходит для 6 применениеs: PCI Bus Interface Bridge, Industrial Glue Logic Replacement, Legacy Telecom Backplane Controller, JTAG-Based Prototyping Platform, VME / CPCI Legacy Slot Card, Test and Measurement Front-End.
PCI Bus Interface Bridge
The EPF8636AQC160-4N is purpose-built for PCI Local Bus Specification-compliant bridges in legacy industrial PCs and embedded backplanes. Its PCI SIG compliance and 5 V / 3.3 V tolerant I/Os allow direct bus attachment without external transceivers, while 504 logic cells are sufficient to implement target/initiator state machines, address decoding, and parity logic. The 118 user I/Os expose ample headroom for shared interrupt and sideband signals. Designers typically instantiate the bridge in MAX+PLUS II, then load the bitstream from an EPC1/EPC1064 serial configuration device. Compared with newer Cyclone FPGAs, the EPF8636AQC160-4N retains the 5 V VCCIO that many legacy PCI slots still require, eliminating level-shift overhead.
Рекомендуется
Industrial Glue Logic Replacement
The EPF8636AQC160-4N serves as a single-chip replacement for dozens of 74-series glue-logic devices on legacy industrial control boards. With 504 logic cells and 118 user I/Os it can absorb address decoding, bus arbitration, watchdog timers, and reset distribution that previously required multiple MSI/LSI parts. Its 5 V tolerant I/Os interface directly to legacy 74LS/74HC logic, and JTAG boundary-scan (IEEE 1149.1-1990) simplifies board-test routines on the production line. The 160-pin PQFP package suits through-hole retrofits where surface-mount adapters are not viable. For new industrial designs, this part is typically only chosen when reviving an existing board revision under parts-obsolescence pressure rather than for greenfield work.
Рекомендуется
Legacy Telecom Backplane Controller
The EPF8636AQC160-4N is commonly deployed as a backplane controller in legacy telecom shelves where 5 V signalling and PCI-like parallel buses are still in service. Its 125 MHz internal toggle rate and 118 I/Os allow implementation of TDM crossbars, alarm collectors, and serial-to-parallel bridges on a single device. SRAM-based configuration permits remote in-circuit reconfigurability (ICR) for field firmware updates without board swap. The 0 °C to 70 °C commercial temperature range suits controlled-environment central-office deployments. Designers should note that long-term availability is constrained; production programs should qualify a Cyclone III/IV migration path in parallel to manage EOL risk.
Рекомендуется
JTAG-Based Prototyping Platform
The EPF8636AQC160-4N is a strong fit for university and R&D prototyping boards that use JTAG (IEEE 1149.1-1990) for both configuration and boundary-scan test. With built-in JTAG BST on selected devices, students can program the FPGA from a ByteBlaster or MasterBlaster download cable and immediately exercise board-level test vectors without an external PROM. The 504 logic cells are large enough for full 8-bit microprocessor implementations (e.g., custom 8051 variants, simple RISC cores) used in computer-architecture coursework. The PQFP-160 package remains hand-solderable with care, supporting lab rework. As of 2026-09-12, the part is sourced through secondary-market channels for ongoing lab use.
Рекомендуется
VME / CPCI Legacy Slot Card
The EPF8636AQC160-4N is widely used on legacy VMEbus and CompactPCI peripheral cards where 5 V signalling and PCI compliance are mandatory. Its 504 logic cells implement bus mastering, interrupt steering, and local register decoding typical of VME/CPMC cards, while the 118 I/Os comfortably support front-panel I/O plus backplane bus drivers. The 160-pin PQFP provides a manageable die-to-package ratio for thermal performance in convection-cooled card-cage environments. Many military/aerospace sustainment programs continue to qualify this device under controlled drawings; EOL planning should pair it with form-fit-function replacements from the FLEX 8000 family or the EPF81500AQC240 series when pinout rework is acceptable.
Рекомендуется
Test and Measurement Front-End
The EPF8636AQC160-4N is well suited to legacy test-and-measurement front-ends such as logic-analyzer pods, pattern-generator channels, and boundary-scan controllers. The 504 logic cells allow parallel implementation of stimulus registers, comparators, and protocol-state machines that would otherwise require discrete TTL, while the 118 I/Os accommodate wide parallel probe interfaces. JTAG BST (IEEE 1149.1-1990) compliance simplifies integration into ATE fixtures. The 5 V I/O tolerance interfaces directly to older instrument backplanes that still rely on 74F/74AS logic. Engineers modernizing these instruments should note that this device supports the full IEEE 1149.1 boundary-scan instruction set including EXTEST, SAMPLE/PRELOAD, and BYPASS.

Заметки по проектированию
Estimated: at 5 V VCC with 50% toggle rate on all 118 user I/Os, I/O current draw is dominated by capacitive load charging. Use bulk decoupling of 100 µF tantalum plus 0.1 µF ceramic per VCC pin, and place a 1 µF tantalum near each VCCINT pin. The FLEX 8000 datasheet recommends placing one decoupling capacitor within 5 mm of every VCC/GND pin pair. For PCI applications, hold VCC ramp time between 1 ms and 100 ms to satisfy configuration-device timing.
Do not assume all 160 PQFP pins are user I/O - the EPF8636AQC160-4N dedicates specific pins to JTAG (TCK, TMS, TDI, TDO), configuration (nCONFIG, CONF_DONE, nSTATUS), and power (VCCINT, VCCIO, GND). Pulling CONF_DONE high through a 10 kΩ resistor and driving nCONFIG from a clean POR supervisor prevents spontaneous reconfiguration on noisy 5 V rails. Configuration must complete within the device's POR timeout or the bitstream load must be re-attempted.
The 160-pin PQFP has 0.65 mm pitch leads; route all signals on inner layers with 0.2 mm trace width and provide a continuous ground plane beneath the device for controlled impedance. Keep JTAG trace lengths below 50 mm to avoid signal-integrity issues. For production boards, expose JTAG header pins (TCK, TMS, TDI, TDO, GND) to enable in-system programming via ByteBlasterMV or MasterBlaster cables.
Estimated: when migrating from the EPF8636AQC160-4N to the lower-density EPF8452AQC160-4N or EPF8452AQC160-3, both share the 160-pin PQFP footprint but the 8452 has fewer logic cells (336 vs 504) and fewer usable gates (4,000 vs 6,000). Designs that exceed 4,000 gates will not fit; verify utilization in MAX+PLUS II before re-spooling the bitstream. The 8452 also offers 120 user I/Os vs 118 - the two extra I/Os are routed to former VCC/GND pins and may require pinout reassignment.
Информация о соответствии
Compliance data not present in the verified web data; the EPF8636AQC160-4N is a 1990s-era legacy device whose original PQFP package was typically leaded (SnPb). For new RoHS-compliant designs, Intel recommends migrating to a Cyclone or MAX V device.
