EPF8820AQC208-3 概要

The Altera (Intel) EPF8820AQC208-3 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), housed in a 208-pin Plastic Quad Flat Pack (PQFP) package with 152 user I/Os. It integrates 672 logic elements and 8,000 usable gates, organized into 84 Logic Array Blocks (LABs), and operates from a 5 V supply (4.75 V to 5.25 V).

A Field Programmable Gate Array (FPGA) is a semiconductor IC built around an array of configurable logic blocks (CLBs/LABs) connected by programmable interconnect. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit between fixed-function ASICs and discrete logic in the design hierarchy. Unlike gate arrays or standard-cell ASICs, FPGAs are reprogrammed in-circuit, accelerating prototyping and reducing non-recurring engineering (NRE) cost.

The FLEX 8000 architecture combines a fine-grained logic fabric with dedicated FastTrack interconnect and a continuous SRAM configuration memory. Each LAB contains 8 logic elements (LEs) and local interconnect, while FastTrack rows and columns provide predictable, tpd-independent delays across the device. The EPF8820AQC208-3 also features built-in JTAG (IEEE 1149.1) boundary-scan support and in-circuit reconfigurability (ICR) via external EPROM (EPC1, EPC1064, EPC1213, EPC1441) or a system controller.

Typical applications include glue-logic replacement, peripheral bus bridging, custom state-machine controllers, telecom interface glue, and industrial control front-ends. The 152 available I/Os at 5 V tolerance (commercial grade 0C to 70C) make it well suited to legacy TTL/CMOS bus interfaces. The device is also commonly deployed as a hardware accelerator for DSP pre/post-processing in cost-sensitive systems where modern FPGAs are over-spec.

When designing with this part, note that the EPF8820AQC208-3 is marked Obsolete/EOL per the latest distributor listings; only remaining stock and refurbished supply are available. Designers should validate long-term availability for new production and consider modern Cyclone or MAX series as functionally equivalent drop-in alternatives where possible.

This page synthesizes distributor pricing, pin-to-pin compatible alternatives from the Altera FLEX 8000 family, and design notes not found on the original Altera datasheet, including context on SRAM configuration and JTAG testing for legacy designs.

主な用途

EPF8820AQC208-3 の用途: 6 件s: Legacy Telecom Glue Logic, Industrial Control Front-End, Custom Peripheral Bus Bridge, Hardware State-Machine Controller, DSP Pre/Post-Processing Accelerator, Test & Measurement Fixture Logic.

🌐

Legacy Telecom Glue Logic

The EPF8820AQC208-3 fits telecom glue-logic designs thanks to its 152 5V-tolerant I/Os that connect directly to legacy TTL/CMOS bus peripherals without level shifters. With 672 LEs across 84 LABs it bridges E1/T1 framers, HDLC controllers, and time-slot interchangers at line rates up to tens of MHz. Unlike smaller CPLDs, the FastTrack interconnect delivers uniform tpd across the die, simplifying timing closure when fanning out to multiple bus segments. A typical circuit places the EPF8820AQC208-3 between a framer IC and a backplane transceiver, with JTAG access for boundary-scan production test.

🏭

Industrial Control Front-End

The EPF8820AQC208-3 is widely deployed in industrial PLC and motion-control front-ends because its 5 V I/O tolerance mates directly with 24 V isolated digital inputs and 5 V sensor buses via external buffers. The 672-LE capacity is sufficient for PWM generation, encoder decoding (incremental and SSI), and custom deterministic state machines. The commercial 0C to 70C operating range suits cabinet-mounted controllers, while JTAG boundary-scan accelerates in-circuit test on densely populated backplanes. Designers benefit from FastTrack predictable routing when fanning out 100+ control signals across multiple connector banks.

🖥️

Custom Peripheral Bus Bridge

With 152 user I/Os and 8,000 usable gates, the EPF8820AQC208-3 can implement multi-master bus bridges between legacy ISA, PC/104, and proprietary peripheral buses. Its SRAM-based fabric lets designers iterate bridge protocols during system bring-up without mask charges, and JTAG enables live reconfiguration of bus protocol state machines during field debug. The 208-pin PQFP footprint offers ample 5V-tolerant I/O for both address/data multiplexing and interrupt/control signal replication. Compared to a discrete 74-series implementation, the EPF8820AQC208-3 reduces PCB area by 5-10x and consolidates timing-critical glue into one timing-closed device.

🔧

Hardware State-Machine Controller

The EPF8820AQC208-3 excels at implementing complex, multi-state control sequencers that would otherwise require dozens of PAL/GAL devices. With 84 LABs it can hold 50+ parallel finite state machines plus their interlock logic, and its SRAM configuration enables late-stage firmware changes. The 5V I/Os interface directly to opto-isolated industrial outputs, while the JTAG TAP controller provides a window into internal states during integration testing. Designers typically use MAX+PLUS II to enter state machines as AHDL/Verilog and synthesize into the device. Compared to a microcontroller, the FPGA delivers deterministic single-clock-cycle state transitions without RTOS overhead.

📺

DSP Pre/Post-Processing Accelerator

In cost-sensitive DSP subsystems, the EPF8820AQC208-3 acts as a hardware accelerator for FIR filtering, data formatting, and protocol encapsulation offloaded from a host DSP. Its 672 LEs support 16-tap FIR filters or parallel CRC engines running at full 5V I/O speeds, and FastTrack interconnect ensures uniform sample-to-sample timing. Designers often pair the FPGA with a serial EEPROM configuration device (EPC1 or EPC1064) for fast power-up boot, and route JTAG to a header for emulator access. Compared to a DSP software implementation, the FPGA variant typically delivers 3-10x throughput per MHz while freeing the host DSP for control tasks.

🔬

Test & Measurement Fixture Logic

The EPF8820AQC208-3 is a strong fit for ATE pin-card and bed-of-nails fixture logic, where 152 5V I/Os connect to UUT pins through relays and the FPGA orchestrates stimulus/response sequences. Its SRAM fabric lets test engineers swap personality bitstreams for different UUTs in seconds, and JTAG provides full visibility into FPGA states during fixture bring-up. The commercial temperature range suits bench fixtures, while the 208-PQFP is easy to socket or rework. Designers appreciate the deterministic FastTrack delays when sequencing parallel test vectors to multiple UUT pins at once.

The official Altera FLEX 8000 datasheet is hosted at alterasemi.com/datasheet/alterasemi/EPF8820AQC208-3.pdf. This PDF covers architecture, DC characteristics, AC switching characteristics, JTAG BSDL, and configuration timing for the entire FLEX 8000 family including the EPF8820AQC208-3.
Can a Cyclone or MAX FPGA replace EPF8820AQC208-3?
A modern Intel Cyclone IV or MAX II device can functionally replace the EPF8820AQC208-3, but it is NOT pin-to-pin compatible. Any replacement requires PCB rework, footprint change, and re-synthesis in Quartus II because both the package and the logic architecture differ.
Does EPF8820AQC208-3 support JTAG boundary scan?
Yes, the EPF8820AQC208-3 includes built-in JTAG (IEEE 1149.1) boundary-scan support, allowing production test access to all 152 user I/Os and the configuration interface. JTAG also enables in-system programming via the same TAP controller used for production test.
What are the key specifications of EPF8820AQC208-3 that engineers should know?
The EPF8820AQC208-3 integrates 672 logic elements across 84 LABs, supports 152 user I/Os at 5 V (4.75 V to 5.25 V) supply, and operates commercially from 0 C to 70 C. It uses SRAM configuration loaded from EPC1/EPC1064/EPC1213/EPC1441 EPROMs, supports JTAG 1149.1 boundary scan, and ships in a 28 mm x 28 mm 208-pin PQFP. Status is Obsolete/EOL.

選定ガイド

Choose the EPF8820AQC208-3 for legacy 5V glue-logic designs that require 152 I/Os at 5 V tolerance and 672 LEs of logic capacity. For designs needing faster timing closure, the EPF8820AQC208-2N offers the -2 speed grade in the identical 208-PQFP footprint. For higher logic capacity in the same package, upgrade to the EPF81188AQC208-3 which provides 1,188 LEs (+77%) in the identical footprint. For cost-sensitive designs that can accept fewer I/Os, the EPF8820AQC160-3/-4 options pack the same die into a smaller 160-pin PQFP. None of these alternatives are modern - the entire FLEX 8000 family is EOL - so use this part only for legacy support, not new production.

設計ノート

The EPF8820AQC208-3 requires a clean 5 V supply (4.75 V to 5.25 V) with adequate decoupling. Place one 0.1 uF ceramic capacitor per VCC pin pair and one bulk 22-47 uF tantalum or aluminum polymer capacitor near each VCC bank. SRAM-based FPGAs draw surge currents during configuration; the bulk capacitor prevents VCC droop that can cause configuration failures. Estimated: at 25 MHz toggle activity on 100 I/Os, ICCINT is typically 150-250 mA; size the regulator for at least 1.5x this value plus headroom for inrush.

Use a 4-layer PCB with dedicated VCC and GND planes for the EPF8820AQC208-3. Route all 152 user I/Os on short, matched traces and avoid 90-degree bends to reduce reflections on 5V TTL-level signals. Place configuration EPROM (EPC1/EPC1064/EPC1213/EPC1441) within 50 mm of the FPGA to keep configuration traces short. Expose JTAG pins (TCK, TMS, TDI, TDO, nCONFIG, nSTATUS, CONF_DONE) to a 0.1-inch header or 10-pin JTAG ribbon for debug and production programming.

Because the EPF8820AQC208-3 is marked Obsolete/EOL, do not use it for new production designs without a written last-time-buy commitment from Altera/Intel. Modern designs should target Cyclone IV, MAX II, or MAX V as functionally equivalent replacements, but note that none of these are pin-compatible - a PCB redesign is required. For legacy support, qualify a single broker-sourced lot and verify authenticity before use.

The 208-pin PQFP package has relatively long lead inductance (~5-7 nH) that can create ground bounce on heavily-loaded outputs. Use series damping resistors (22-33 ohm) on outputs driving backplane connectors, and avoid simultaneous switching of more than 16 outputs per bank. For clock distribution, dedicate one global FastTrack buffer per clock domain to minimize skew.
