EPF8636AQC160-4 Présentation

The Intel (formerly Altera) EPF8636AQC160-4 is a member of the FLEX 8000 family of CMOS SRAM-based FPGAs, delivering approximately 6,000 usable gates with 504 logic elements housed in a 160-pin Power Quad Flat Pack (PQFP) package. The device is fabricated on a 0.42 µm CMOS process and supports a maximum toggle frequency of 125 MHz, making it suitable for glue-logic, bus-interface, and state-machine designs in legacy systems.

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.

Applications typiques

EPF8636AQC160-4 convient pour 6 applications: 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.

🌐

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.

🧩

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.

📊

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.

🖥️

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.

🔧

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.

What family does the EPF8636AQC160-4 belong to?
The EPF8636AQC160-4 is a member of the Intel (formerly Altera) FLEX 8000 family of CMOS SRAM-based FPGAs, fabricated on a 0.42 µm process and packaged in a 160-pin PQFP. According to the Altera datasheet, the FLEX 8000 family targets glue-logic, bus-bridge, and state-machine applications that require between 2,500 and 16,000 usable gates with predictable FastTrack interconnect routing.
How many usable gates and logic elements does the EPF8636AQC160-4 contain?
The EPF8636AQC160-4 contains 504 logic elements and is rated for approximately 6,000 usable gates. According to FLEX 8000 family documentation, usable-gate counts are lower than the raw register-plus-interconnect equivalent because routing overhead is subtracted; designers should plan board-level logic capacity against the 6,000-gate figure rather than the maximum die capacity.
What is the maximum operating frequency of the EPF8636AQC160-4?
The EPF8636AQC160-4 has a maximum toggle frequency of 125 MHz for the -4 speed grade, which is the slowest commercial bin in the FLEX 8000 family. Faster -3, -2, and -1 speed grades are available in the same package; the -4 grade was selected for cost-sensitive legacy designs where frequency headroom was not a critical constraint.
What is the supply voltage and I/O configuration of the EPF8636AQC160-4?
The EPF8636AQC160-4 operates from a 5 V core supply and supports MultiVolt I/O, allowing each I/O bank to be configured for either 3.3 V or 5.0 V operation. According to the FLEX 8000 datasheet, this MultiVolt feature permits mixed-voltage interfacing on a single die, simplifying designs that must bridge legacy 5 V peripherals with 3.3 V processors on the same board.
Is the EPF8636AQC160-4 still in production?
No, the EPF8636AQC160-4 is classified as obsolete and is no longer in active production. The FLEX 8000 family has been superseded by Intel's MAX-series CPLDs and Cyclone-series low-cost FPGAs. Stock is available only through distributors holding legacy inventory, and unit prices have risen substantially compared to the original 1990s list price.
Where can I buy the EPF8636AQC160-4 today?
The EPF8636AQC160-4 can be sourced from authorized and independent distributors including DigiKey, Mouser, Octopart-listed vendors, Avaq, Xecor, and Jotrin Electronics.

Where can I find the EPF8636AQC160-4 pinout?
The EPF8636AQC160-4 pinout is documented in the Altera FLEX 8000 family datasheet under the 160-pin PQFP package section, showing the assignment of 118 user I/O pins, dedicated configuration pins (MSELn, nSTATUS, CONF_DONE, DCLK, DATA0), JTAG pins (TDI, TMS, TCK, TDO), power (VCCINT, VCCIO), and ground pins. Cross-reference this against the package land pattern when laying out a replacement board.
Is there a modern Intel FPGA equivalent to the EPF8636AQC160-4?
Modern Intel FPGAs functionally equivalent to the EPF8636AQC160-4 include members of the MAX II, MAX V, MAX 10, and Cyclone IV / Cyclone 10 LP families, depending on required logic density, I/O count, and supply voltage. None share the 160-pin PQFP footprint, so migration requires PCB rework; designers should plan for new land patterns and 1.8 V or 3.3 V core supplies during migration.

Guide de sélection

Choose the EPF8636AQC160-4 only for legacy field replacement where the original FLEX 8000 design is already implemented on a 160-pin PQFP footprint. For new designs, choose MAX II/MAX V CPLDs when logic capacity below 5,000 gates suffices, or Cyclone IV/Cyclone 10 LP FPGAs when more logic and modern features are needed - none of these modern parts share the 160-pin PQFP footprint, so PCB rework is required. Within the FLEX 8000 family, choose EPF8636AQC160-3 if extra timing margin is needed, EPF8636AQC160-4N for RoHS-compliant builds, or EPF8452AQC160-4 when the design fits 4,500 usable gates and cost reduction is the priority. All drop-in alternatives share the same 160-pin PQFP land pattern, enabling PCB reuse across the FLEX 8000 160-pin PQFP family.

Notes de conception

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.

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.
