EPF8820AQC208-2 Обзор

The Altera (Intel Programmable Solutions Group) EPF8820AQC208-2 is a member of the FLEX 8000 family of CMOS Field-Programmable Gate Arrays (FPGAs), delivering approximately 8,000 usable gates, 672 logic cells (also referred to as registers), and 152 user I/Os at a maximum toggle frequency of 125 MHz, all in a 208-pin Power Quad Flat Pack (PQFP) package. The device operates from a 5 V supply and is specified over the commercial 0 C to 70 C temperature range, targeting glue-logic, bus-interface, and state-machine replacement in legacy 5V designs.

A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines an array of configurable logic blocks (CLBs), a programmable interconnect fabric, and programmable I/O cells. Within the broader semiconductor taxonomy, an FPGA belongs to: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. FPGAs differ from CPLDs primarily by their SRAM-based configuration memory and finer-grained architecture, and they are typically used where high gate counts, register-rich designs, or in-system reconfigurability are required.

The FLEX 8000 family is implemented in a 5 V CMOS process with on-chip SRAM configuration memory. Each logic element (LE) contains a 4-input look-up table, a programmable register, and dedicated carry and cascade chains, allowing efficient implementation of arithmetic and wide fan-in logic. The interconnect uses continuous, fast-path lines across the entire die for predictable timing, and the device supports in-circuit reconfigurability (ICR) via external configuration devices, enabling field upgrades without removing the part from the system.

Key features of the EPF8820AQC208-2 include 84 Logic Array Blocks (LABs) of 8 LEs each (672 LEs total), 152 user I/O pins with 5 V tolerant I/O buffers, JTAG-based boundary-scan testing compliant with IEEE 1149.1, and a dedicated configuration interface. The PQFP-208 package provides gull-wing leads on a 28 mm x 28 mm body suitable for standard surface-mount assembly with a 0.5 mm lead pitch.

Typical applications include bus-interface bridging (PCI, ISA, VME), glue logic replacement for discrete 74-series TTL/CMOS, industrial control state machines, prototyping ASICs, and legacy telecom/datacom equipment that still operates from 5 V rails. The combination of high I/O count and 5V tolerance makes the EPF8820AQC208-2 well suited for backplane interfacing where 5V signaling is mandatory.

When designing with this part, note that FLEX 8000 devices are SRAM-based and require a configuration ROM on every power-up; JTAG programming alone does not retain the design. Designers should also verify that the 5V I/O tolerance is compatible with downstream devices and consider using series resistors or bus-switches when bridging to 3.3V peripherals. As the FLEX 8000 family is long since EOL/NRND, second-source qualification of pin-compatible alternatives is recommended for new designs.

Типичное применение

EPF8820AQC208-2 подходит для 6 применениеs: 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.

🔬

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.

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.

Where can I download the EPF8820AQC208-2 datasheet PDF?

The EPF8820AQC208-2 datasheet PDF is hosted on the Altera/Intel PSG FLEX 8000 family datasheet page (dsf8000.pdf).

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.

Заметки по проектированию

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.
