EPF8636AQC160-5 Tóm tắt

The Intel / Altera EPF8636AQC160-5 is a member of the FLEX 8000 family of CMOS SRAM-based FPGAs, delivering 6,000 usable gates, 504 logic elements (cells), and 636 flip-flops in a 160-pin Plastic Quad Flat Pack (PQFP) package. Manufactured on a 0.42 µm CMOS process, the device supports a 5 V core supply with 3.3 V or 5 V configurable I/O operation and runs system clock rates up to 125 MHz.

An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks, programmable interconnect, and I/O cells that the user defines after manufacturing. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs), which also include CPLDs and SPLDs. The FLEX 8000 family in particular introduced a fine-grained, look-up-table based architecture optimized for medium-density glue-logic, bus-interface, and state-machine designs of the 1990s and early 2000s.

Key features of the EPF8636AQC160-5 include 6K gates of logic, 504 logic cells (LCs), 636 flip-flops, in-system programmability via SRAM configuration, and JTAG boundary-scan support. The device is reconfigurable in-circuit, allowing iterative design without UV erasure, and offers 5 V tolerant I/O operation. The architecture uses a 0.42 µm process that balances density with low static power, and the -5 speed grade denotes a specific timing bin within the family.

Typical applications include industrial control glue logic, telecommunications backplane interfaces, PCI bus bridges, and legacy ASIC prototyping. Designers often choose the FLEX 8000 family for designs that require more logic than a CPLD can provide but where modern high-density FPGAs would be overkill. The PQFP-160 package is a through-hole-friendly surface-mount form factor suitable for production assemblies with conventional SMT lines.

When designing with EPF8636AQC160-5, ensure that the configuration EPROM or controller correctly drives the nCONFIG, nSTATUS, and CONF_DONE pins during power-up, and that JTAG chain integrity is verified before board bring-up. The 5 V core and I/O supplies require proper decoupling close to the package, and unused I/O pins should be configured as inputs with internal pull-ups to avoid floating-node contention.

This page synthesizes distributor pricing, drop-in FLEX 8000 family alternatives from the same Altera/Intel product line, and practical design notes that go beyond the manufacturer datasheet alone.

🏭

Industrial Control Glue Logic

The EPF8636AQC160-5 fits industrial control glue logic by offering 504 logic cells and 636 flip-flops in a 5 V-tolerant PQFP-160 package that integrates directly with legacy 5 V PLC backplanes. Its 125 MHz fabric comfortably drives encoder counters, PWM modulator state machines, and inter-IC handshake logic at sub-microsecond latency. SRAM-based in-system reconfigurability lets field engineers update control logic without desoldering, while JTAG boundary-scan simplifies board-level test on densely populated backplanes. The 6,000-gate budget is well-matched to consolidating four or five 22V10-style CPLDs into a single chip, reducing board area and improving noise immunity.

Telecommunications Backplane Bridge

The EPF8636AQC160-5 suits telecom backplane bridging where the device must arbitrate between E1/T1 framers, route HDLC channels, and present a clean interface to an upstream processor. Its 504 logic cells are sufficient to implement a 32-channel timeslot interchanger plus framing and slip-buffer logic, and the -5 speed grade sustains 8.192 MHz backplane operation with timing margin. 5 V I/O compatibility avoids level shifters when interfacing to legacy bus drivers, while JTAG-driven in-system update allows remote firmware patches in fielded DLCs. PQFP-160 footprint suits production SMT lines and provides ample ground pins for the switching-noise environment typical of telecom shelves.

🔧

Legacy ASIC Prototyping

The EPF8636AQC160-5 is a proven vehicle for prototyping legacy ASIC designs that the original design team specified in FLEX 8000 fabric before tape-out. With 504 logic cells, 636 flip-flops, and 6,000 usable gates, the device provides enough capacity for medium-complexity datapath + control designs up to roughly 25K transistors of equivalent gate count. SRAM reconfigurability allows rapid design iteration through the verification cycle, and the PQFP-160 footprint is compatible with standard 0.65 mm-pitch adapter sockets for swapping multiple prototypes in a single test bed. Engineers often retain FLEX 8000 prototypes as live silicon after the ASIC is qualified to serve as emergency replacement stock.

PCI Bus Interface Bridge

The EPF8636AQC160-5 fits PCI bridge and endpoint implementations at the 33 MHz, 32-bit PCI 2.1 bus rate, where its -5 speed grade comfortably closes timing on the 7.5 ns Tsu/Th window. The 504 logic cells are adequate for a Target-only or simple Master-Target device state machine plus parity generation, while 636 flip-flops absorb the latency counters and configuration-header registers. 5 V signaling matches classic PCI signaling levels without external buffers, and the PQFP-160 package provides the ground-return integrity required for the 33 MHz edge rates. Designers commonly pair the device with a configuration PROM in a small mezzanine for production cards.

🔬

Test & Measurement Instrumentation Front-End

The EPF8636AQC160-5 is well-suited to test-and-measurement front-ends that require custom timing generators, scan controllers, or stimulus-pattern sequencers. Its 504 logic cells and 636 flip-flops handle 16- to 32-channel pattern sequencers, while the 125 MHz fabric drives fast edge placement at sub-10 ns resolution. 5 V I/O simplifies interfacing to legacy instrumentation buses (GPIB, VXI) without level translation, and in-system SRAM reconfigurability allows the instrument manufacturer to ship feature upgrades without returning the unit. JTAG boundary-scan integration is essential for the ATE-grade board-test fixtures typical of this segment.

Avionics Databus Interface (Legacy)

The EPF8636AQC160-5 has been used for MIL-STD-1553 and ARINC 429 databus interface cards where its 504 logic cells encode/decode the protocol state machines and buffer the time-tag counters. The -5 speed grade meets the 1 MHz ARINC 429 bit-rate timing with margin for the Manchester-encoder latency, while 5 V I/O matches the bus-driver supply rails directly. PQFP-160 package fits standard 6U VME / VXI card outlines. Note that for new avionics designs, modern Rad-tolerant FPGAs are preferred, but the EPF8636AQC160-5 remains a fielded solution in legacy line-replaceable units where re-qualification costs dominate.

What is the logic capacity of EPF8636AQC160-5?

The EPF8636AQC160-5 contains 504 logic cells (LCs), 6,000 usable gates, and 636 flip-flops. According to the Altera FLEX 8000 datasheet family, this places it in the mid-density tier of the FLEX 8000 family, well-suited for glue logic, state machines, and bus-interface designs where modern high-density FPGAs would be overkill but a CPLD lacks sufficient logic resources.

What is the maximum operating frequency of EPF8636AQC160-5?

The EPF8636AQC160-5 supports system clock frequencies up to 125 MHz in the -5 speed grade. Per the Altera FLEX 8000 family datasheet, actual achievable frequency depends on the design's logic depth and routing, but the -5 bin is the fastest grade offered for the EPF8636 die, making it suitable for many 33 MHz and 66 MHz bus-interface applications of its era.

Does EPF8636AQC160-5 require a configuration PROM?

Yes, the EPF8636AQC160-5 uses SRAM-based configuration and requires an external configuration device (such as the Altera EPC1 or EPC1064) or a microcontroller to load the bitstream at power-up. The configuration data is volatile, so the FPGA must be reconfigured after every power cycle unless the configuration source remains active on the board.

What is the difference between EPF8636AQC160-5 and EPF8636AQC160-4?

The EPF8636AQC160-5 is the -5 speed grade (fastest), while the EPF8636AQC160-4 is the -4 speed grade (slightly slower). Both share the same PQFP-160 package, 504 logic cells, 636 flip-flops, and 5 V core. The -5 grade is preferred when timing closure is tight; the -4 grade is typically lower cost and adequate for slower designs.

The EPF8636AQC160-5N is the lead-free / RoHS-compliant variant of the EPF8636AQC160-5. Choose EPF8636AQC160-5N for RoHS-compliant assemblies and modern reflow profiles; choose EPF8636AQC160-5 only when matching a legacy non-RoHS bill of materials. Both share the same PQFP-160 footprint and 504 LC / 636 FF logic resources.

What is the best drop-in replacement for EPF8636AQC160-5?

The closest drop-in replacement for EPF8636AQC160-5 in the same PQFP-160 footprint is the EPF8636AQC160-5N (RoHS variant) or the EPF8636AQC160-4 / EPF8636AQC160-4N (slower -4 speed grade). All four parts share identical pinout and die; only speed grade and lead-finish differ, so substitution requires no PCB rework.

When should I choose EPF8636AQC160-5 over a modern Cyclone FPGA?

Choose EPF8636AQC160-5 only when maintaining a legacy design that cannot be re-qualified, when replacing failed boards in fielded equipment, or when the bitstream is locked to the FLEX 8000 architecture. For new designs, a modern Cyclone IV or Cyclone 10 LP device offers dramatically higher density, lower power, and modern tool support at lower cost.

Where to download EPF8636AQC160-5 datasheet PDF?

The EPF8636AQC160-5 datasheet is available from the Altera FLEX 8000 family datasheet (DSDF8000) hosted on Intel's Altera documentation archive. As of 2026-09-12, the canonical URL is https://www.altera.com/literature/ds/dsf8000.pdf. You may also find the family datasheet mirrored at FPGAkey and other FPGA-focused archives.

Where can I find the EPF8636AQC160-5 pinout?

The complete PQFP-160 pinout for EPF8636AQC160-5 is provided in the Altera FLEX 8000 family datasheet. Pin functions include dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0), JTAG pins (TDI, TDO, TMS, TCK), user I/O banks, and global clock/clear buffers. Refer to the datasheet pin tables for the exact PQFP-160 ball-out.

What are the key specifications of EPF8636AQC160-5 that engineers should know?

The EPF8636AQC160-5 integrates 504 logic cells, 636 flip-flops, 6,000 usable gates, and supports up to 125 MHz operation in the -5 speed grade. It uses 5 V core supply with 3.3 V / 5 V configurable I/O, is built on a 0.42 µm CMOS SRAM process, and ships in a PQFP-160 package. Configuration is volatile via JTAG or an external EPC-series configuration PROM.

Is EPF8636AQC160-5 the same as EPF8452AQC160-5?

No. The EPF8636AQC160-5 (6,000 gates, 504 LCs) is a larger FLEX 8000 device than the EPF8452AQC160-5 (4,000 gates, 336 LCs). Both share the PQFP-160 package, so footprint-compatibility is preserved, but bitstreams are NOT interchangeable. The EPF8636 has 50% more logic and is the correct choice when EPF8452 capacity is exceeded.

What is the price of EPF8636AQC160-5 in 2026?

As of 2026-09-12, EPF8636AQC160-5 pricing starts at approximately USD 28.50 per unit at qty-1, decreasing to about USD 14.95 per unit at qty-1000 across specialist obsolete-component distributors. Prices reflect scarcity rather than production cost; expect negotiation room at higher volumes, and always verify date code and RoHS status before PO release.

Dữ liệu tham khảo kỹ thuật cho EPF8636AQC160-5 — so sánh, hướng dẫn thiết kế và thông tin tuân thủ.

Hướng dẫn chọn lựa

Choose the EPF8636AQC160-5 when maintaining a legacy FLEX 8000 design that requires the fastest speed grade and tolerates a leaded finish. Choose EPF8636AQC160-5N for the same design but in a RoHS-compliant assembly. Choose EPF8636AQC160-4 when timing closure is achievable at the -4 grade (typically ~10-15% slower) and a lower unit price is preferred. Choose EPF8636AQC160-3 for cost-sensitive designs at the slowest speed grade. Choose EPF8452AQC160-5 only when the design fits within 336 LCs / 4K gates — the smaller die is cheaper but not interchangeable at the bitstream level. For new designs, evaluate modern Cyclone IV or Cyclone 10 LP devices, which offer higher density at lower cost.

Ghi chú thiết kế

The EPF8636AQC160-5 requires two supply rails: VCCINT = 5 V for the core logic and VCCIO = 3.3 V or 5 V for the I/O banks (configurable per bank). Place a 0.1 µF decoupling capacitor within 3 mm of every VCC and VCCIO pin, and add a 10 µF bulk tantalum or ceramic capacitor near the package. Estimated: at 100% utilization of 504 LCs at 125 MHz, expect roughly 0.5-1.0 A from VCCINT and I/O current depends on switching frequency and load — verify with the FLEX 8000 power estimator in the Altera MAX+PLUS II toolchain.

PQFP-160 has 0.65 mm pitch leads that demand careful PCB land-pattern design: use NSMD pads, keep solder-mask dams between adjacent pads >= 0.2 mm wide, and ensure the copper-pour escape pattern does not neck below 0.15 mm. Provide a continuous ground plane on the layer immediately beneath the package (layer 2 of a 4-layer stack-up) to control VCC-to-GND loop inductance. Stencil aperture should be 1:1 to the pad with a 0.1 mm reduction for fine-pitch QFP packages to prevent solder bridging.

Do not leave the FLEX 8000 configuration pins floating — nCONFIG must be tied to VCC through a 10 kΩ pull-up, and nSTATUS, CONF_DONE, and INIT_DONE are open-drain and require external pull-ups to VCCIO. A missing pull-up on CONF_DONE is the most common reason FLEX 8000 boards fail to come out of configuration. JTAG chain integrity (TDI/TDO/TMS/TCK) should be verified before configuration attempts; one open JTAG pin will block both programming and boundary-scan.

PQFP-160 packages have a θJA of approximately 35-45 °C/W depending on PCB copper area. Estimated: at 1 W total dissipation, junction-to-ambient rise is 35-45 °C. For designs operating at industrial temperature (85 °C ambient), ensure PCB copper pour under the package provides at least 1 sq inch of continuous VCC/GND plane to keep junction temperature within the 125 °C commercial limit. Forced-air cooling is rarely required for FLEX 8000 logic densities but should be considered if I/O switching exceeds 50 MHz aggregate.

Global clock pins GCLK1/GCLK2/GCLK3 drive low-skew clock trees inside the FLEX 8000 fabric — route these as 50 Ω controlled-impedance traces with no stubs. Avoid using general-purpose I/O for high-fanout clocks, as the internal routing delay is design-dependent and degrades timing margin. Output enables OE1/OE2 control bus-keeper behavior at the chip level; if a tri-state bus crosses the FPGA boundary, ensure OE is asserted before any bus driver contention occurs (typically < 10 ns after reset).
