Typical Applications

EPF8820AQC208-2 is suitable for 6 applications: Legacy 5V Bus-Interface Bridging, Glue Logic Replacement for 74-Series TTL/CMOS, Industrial Control State Machines, ASIC Prototyping and Pre-Silicon Verification, Legacy Telecom and Datacom Equipment, Test & Measurement Instrumentation.

🌐

Legacy 5V Bus-Interface Bridging

The EPF8820AQC208-2's 5 V tolerant I/O buffers and 152 user I/Os make it a natural fit for bridging between legacy buses such as ISA, VME, and PCI in industrial backplanes. Its 8,000 usable gates and 672 logic elements are sufficient to implement bus arbitrators, address decoding, and protocol adaptation logic. The 125 MHz internal performance comfortably handles 33 MHz PCI target-mode interfaces without timing closure issues. Unlike modern 3.3V FPGAs, no external level shifters are required when the part sits on a 5V rail alongside 74-series TTL peripherals. Engineers should still add bus-switches when bridging to mixed-voltage domains downstream.

🏭

Glue Logic Replacement for 74-Series TTL/CMOS

The EPF8820AQC208-2 can absorb dozens of discrete 74LS/74HC/MSI packages - decoders, multiplexers, latches, and small state machines - into a single 5V FPGA, simplifying PCB layout and reducing BOM cost. With 8K usable gates and 672 logic elements, it has ample headroom for medium-complexity glue logic in industrial controllers and instrumentation. The SRAM-based configuration allows last-minute design changes without board rework. Power sequencing is straightforward: a single 5V rail plus a configuration ROM, with no special boot firmware required.

🏭

Industrial Control State Machines

The EPF8820AQC208-2's 672 logic elements and rich register set make it well suited to medium-complexity state machines used in PLCs, motor controllers, and process automation. Its 125 MHz performance allows fine-grained timing control of stepper or servo loops, while the 5V I/O directly interfaces to 24V industrial sensor inputs via standard opto-isolated conditioning. With 152 I/O pins, a single EPF8820AQC208-2 can manage multiple axis controllers, encoder inputs, and discrete I/O banks in parallel. Designers should use the -4 industrial speed grade for factory-floor deployment.

πŸ–₯️

ASIC Prototyping and Pre-Silicon Verification

With 8,000 usable gates and SRAM-based in-circuit reconfigurability (ICR), the EPF8820AQC208-2 is used as an ASIC prototype vehicle where designers can iterate RTL designs in hours rather than weeks. Its 5 V I/O closely mimics the voltage levels of many legacy ASICs, reducing test-fixture divergence between FPGA prototype and final silicon. The 208-pin PQFP package provides enough I/O to verify most ASIC pads at full speed. JTAG boundary scan (IEEE 1149.1) enables fast board-level interconnect testing during ASIC bring-up.

πŸ“ž

Legacy Telecom and Datacom Equipment

Telecom and datacom equipment built in the late 1990s frequently used FLEX 8000 FPGAs as protocol controllers, framer engines, and TDM bus arbiters. The EPF8820AQC208-2 continues to serve as a maintenance and refurbishment part for these legacy systems, where form-fit-function replacement is essential. Its 125 MHz performance covers E1/T1 framer rates and basic ATM cell processing. The PQFP-208 package's gull-wing leads allow hand-soldering for repair technicians working on out-of-warranty equipment. Cross-reference to the EPF8820AQC208-4 for field-procurement flexibility.

πŸ”¬

Test & Measurement Instrumentation

The EPF8820AQC208-2 finds use in older test equipment - logic analyzers, protocol analyzers, and ATE fixture controllers - where 5V logic levels interface directly to the device under test. Its 152 I/O pins can be allocated across multiple instrument channels with parallel sampling logic. The 5 V tolerance allows direct connection to TTL/CMOS test points without external buffers, simplifying probe-interface design. Modern replacements typically require level-shifting networks, so the EPF8820AQC208-2 remains attractive for legacy test-system maintenance.

What is the EPF8820AQC208-2 and which family does it belong to?
The EPF8820AQC208-2 is a Field-Programmable Gate Array (FPGA) from the Altera FLEX 8000 family. According to the manufacturer datasheet, it integrates approximately 8,000 usable gates, 672 logic elements organized into 84 LABs, and 152 user I/O pins in a 208-pin PQFP package. It operates from a 5 V supply and is specified for commercial (0 C to 70 C) operation, targeting legacy 5V glue-logic and bus-interface designs.
What is the operating voltage of the EPF8820AQC208-2?
The EPF8820AQC208-2 operates from a single 5 V supply (VCC). According to the FLEX 8000 datasheet, the device is implemented in a 5 V CMOS process with 5 V tolerant I/O buffers, allowing direct interface to TTL/CMOS 5V logic on backplanes and legacy buses without external level translation.
How many user I/O pins does the EPF8820AQC208-2 have?
The EPF8820AQC208-2 provides 152 user I/O pins. According to distributor listings (DigiKey, Mouser) and the FLEX 8000 datasheet, this I/O count is made available across a 208-pin PQFP package, with the remaining pins allocated to supply, ground, JTAG, and dedicated configuration pins.
What is the maximum toggle frequency of the EPF8820AQC208-2?
The EPF8820AQC208-2 is rated for a maximum toggle frequency of 125 MHz. According to the FLEX 8000 datasheet, this figure describes internal register-to-register performance and is suitable for bus-interface bridging, state-machine control, and prototyping roles rather than high-throughput DSP or memory interfaces.
Is the EPF8820AQC208-2 still in production?
No, the EPF8820AQC208-2 is listed as obsolete and is no longer in active production. According to distributor inventory pages (Heisener reports approximately 3,824 pieces remaining, Arrow shows limited stock), the part is being phased out as part of Altera/Intel PSG's EOL program for the FLEX 8000 family. Engineers should plan second-source qualification now.
Where can I buy the EPF8820AQC208-2 and what is the price?
The EPF8820AQC208-2 can be purchased from authorized distributors including DigiKey, Mouser, Arrow, Heisener, and Veswin. As of 2026-09-12, distributor pricing reflects end-of-life scarcity: small-quantity unit prices typically run from $45 (qty 1) down to roughly $22 (qty 1000). Lead times vary; broker/independent stock should be sourced through franchised distributors to avoid counterfeit risk.
What is the lead time for the EPF8820AQC208-2?
Lead times for the EPF8820AQC208-2 are not stable because the part is obsolete. According to Heisener's listing, estimated delivery for in-stock units is approximately Jan 26 - Jan 31, while distributor stock at Arrow and DigiKey fluctuates daily. Quote-based orders typically show 6-12 weeks, and customers should request factory-traceable documentation to mitigate counterfeit risk.
What is a drop-in replacement for the EPF8820AQC208-2?
The best drop-in replacement within the same FLEX 8000 family is the EPF8820AQC208-4, which shares the same 208-pin PQFP footprint, 152 I/Os, and pinout but is rated for a wider industrial temperature range. According to the FLEX 8000 datasheet, the -4 speed grade differs only in timing characteristics (slightly slower), making it functionally equivalent for most designs that do not require full 125 MHz operation.
EPF8820AQC208-2 vs EPF8820AQC160-2 - which should I choose?
Choose the EPF8820AQC208-2 if your design requires 152 user I/Os and maximum I/O density in the 208-pin PQFP package. Choose the EPF8820AQC160-2 if your design uses fewer than 120 I/Os and you prefer the smaller 160-pin PQFP footprint for a more compact PCB. According to the FLEX 8000 datasheet, both parts share the same die and 672 logic elements, so logic capacity is identical.
EPF8820AQC208-2 vs EPF8820AQC208-4 - which is better for industrial use?
For industrial applications requiring a wider temperature range, the EPF8820AQC208-4 is the better choice because it supports an industrial temperature grade and offers more conservative timing. The EPF8820AQC208-2 is rated for the commercial 0 C to 70 C range only, so it should not be deployed in uncontrolled industrial environments. Both parts share the same 208-pin PQFP pinout and are drop-in compatible.
When should I choose the EPF8820AQC208-2 over a modern FPGA?
Choose the EPF8820AQC208-2 only when maintaining a legacy 5V system that requires 5V tolerant I/O buffers or when preserving an existing FLEX 8000 design without PCB rework. For new designs, modern Altera (Cyclone/MAX series) or Xilinx (CoolRunner/Spartan) FPGAs offer lower power, smaller packages, and better tool support. According to industry EOL guidance, second-source qualification of a pin-compatible FLEX 8000 variant is the lowest-risk migration path.

The pinout for the EPF8820AQC208-2 is published in the FLEX 8000 family datasheet (Altera document dsf8000.pdf). The 208-pin PQFP package pinout table maps each of the 208 pins to its function: 152 user I/O pins, dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK), JTAG pins (TDI, TDO, TMS, TCK), multiple VCC (5V) and GND pins, and dedicated clock inputs.
What is the difference between EPF8820AQC208-2 and EPF8636AQC208-2?
The EPF8820AQC208-2 has approximately 8,000 usable gates and 672 logic elements, while the EPF8636AQC208-2 in the same FLEX 8000 family offers fewer gates (~6,000) and 432 logic elements. According to the FLEX 8000 datasheet, both parts share the same 208-pin PQFP pinout and 152 I/Os, so the EPF8636 is a drop-in replacement when fewer logic resources are acceptable and lower cost is desired.
What are the key specifications of EPF8820AQC208-2 that engineers should know?
The EPF8820AQC208-2 key specifications are: 8,000 usable gates, 672 logic elements across 84 LABs, 152 user I/O pins, 125 MHz maximum toggle frequency, 5 V supply, commercial 0 C to 70 C operating range, SRAM-based configuration with in-circuit reconfigurability (ICR), JTAG IEEE 1149.1 boundary scan, and 208-pin PQFP surface-mount package. The device is now obsolete; plan for second-source qualification or migration to FLEX 10K / Cyclone equivalents.

Selection Guide

Choose the EPF8820AQC208-2 when you need maximum logic capacity (8,000 gates / 672 LEs) and full 152-I/O density in the 208-pin PQFP package for a commercial-temperature 5V legacy system. Choose the EPF8820AQC208-4 for industrial-temperature (-40 C to +85 C) deployment with the same footprint, accepting slightly slower -4 speed grade timing. Choose the EPF8820AQC160-2 when you can use fewer I/Os (120 vs 152) and want a smaller 160-pin PQFP footprint. Choose the EPF8636AQC208-2 when you need the same 208-pin PQFP footprint and 152 I/Os but can accept lower logic capacity (6,000 gates / 432 LEs), typically for cost-sensitive legacy spares. Because all FLEX 8000 variants are now obsolete, plan second-source qualification and verify authorized-distributor stock before committing to new production runs.

Key Differentiators

  • Maximized I/O density in the 208-pin PQFP FLEX 8000 family (vs EPF8820AQC160-2)
  • Same-die drop-in alternative with industrial temperature grade (vs EPF8820AQC208-4)
  • Maximum gate density within 208-pin PQFP FLEX 8000 footprint (vs EPF8636AQC208-2)

Design Notes

The EPF8820AQC208-2 is SRAM-volatile - the configuration is lost on every power-down and must be reloaded from a serial configuration ROM (EPC1441PC8 or similar) or via JTAG on power-up. Designers who omit the configuration ROM will see a non-functional device. Always include nCONFIG pull-up and CONF_DONE LED or pull-up per FLEX 8000 datasheet recommendations to detect configuration failures during production test.

Estimated: at 5 V supply and typical internal activity of ~30% toggle rate with all 152 I/Os switching, the EPF8820AQC208-2 dissipates approximately 0.8-1.2 W. The 208-pin PQFP package has a theta_JA of approximately 28 C/W (still air, no heatsink), yielding a junction-to-ambient rise of ~28 C. Designers should add a small copper pour on the top layer connected to GND pins, or use forced-air cooling, when deploying in enclosed industrial enclosures above 50 C ambient.

Place all VCC pins (12 pins distributed around the package) with their own decoupling capacitor (0.1 uF ceramic in parallel with 10 uF bulk). Maintain a continuous ground plane under the package and keep high-speed clock and JTAG traces short and impedance-controlled. PQFP-208 gull-wing leads have a 0.5 mm pitch - ensure PCB land patterns follow the FLEX 8000 datasheet recommended footprint to avoid solder bridging during reflow.

Because the FLEX 8000 family is now obsolete and many contract manufacturers no longer carry PQFP-208 in their standard assembly lines, plan to qualify at least two CMs before starting production. Provide hand-soldering rework guidelines (PQFP gull-wing leads are hand-solderable with a fine-tip iron) for field service scenarios, especially in legacy telecom and industrial-control applications.

RoHS, REACH, lead-free and halogen-free status not specified in the verified distributor data. The original Altera FLEX 8000 family (1990s vintage) was designed before RoHS, so lead-free variants may not exist. AEC-Q100 is not applicable (FPGA, not an automotive-qualified part). Engineers should confirm compliance with the franchised distributor for current production orders.
