EPF8820ARC208-2N 개요

The Altera EPF8820ARC208-2N is a member of the FLEX 8000 family of CMOS SRAM-based Field-Programmable Gate Arrays (FPGAs), delivering 8,000 usable gates organized as 672 logic elements (LEs) in a 208-pin RQFP (BFQFP with exposed pad) package. It is fabricated on a 0.42 µm process and operates from a 5 V supply with selectable 3.3 V or 5.0 V VCCIO for output bank compatibility, supporting up to 152 user I/O pins (148 outputs plus 4 dedicated inputs) at toggle frequencies up to 125 MHz.

An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines a matrix of configurable logic blocks (LEs) with programmable interconnect and I/O cells. Within the broader hierarchy, this places it as: programmable logic -> programmable logic device -> integrated circuit -> semiconductor. FLEX 8000 sits between simple PLDs/CPLDs (gate-count-limited) and modern high-density FPGAs, providing register-rich, in-system reconfigurable logic at a low cost per gate.

Key features of the EPF8820ARC208-2N include in-circuit reconfigurability (ICR) via external EPC1, EPC1213, EPC1064, or EPC1441 Altera configuration devices or a system controller, JTAG boundary-scan test support, and tri-state output buffers with programmable slew-rate control. The 208-pin RQFP package provides an exposed thermal pad that reduces junction-to-ambient thermal resistance for higher-power designs.

The FLEX 8000 architecture uses look-up table (LUT)-based logic elements, fast carry chains for arithmetic, a cascade chain for wide fan-in functions, and a hierarchical interconnect with FastTrack routing. The SRAM configuration memory allows unlimited reconfiguration but requires external non-volatile storage, which Altera provides through its dedicated EPC series configuration EPROMs.

Typical applications include telecommunications glue logic, industrial control interfacing, PCI bus bridges, DSP co-processing front-ends, and legacy system prototyping where a 5 V-tolerant, register-rich PLD replaces multiple discrete 74LS/74F TTL packages. Its in-system reconfigurability also suits remote field-upgradeable designs.

When designing with this device, allocate sufficient configuration time during power-up and verify VCCIO levels match downstream logic; mixing 5 V TTL and 3.3 V logic in different I/O banks is supported only with proper bank-by-bank VCCIO selection. The exposed pad of the 208-RQFP must be soldered to a sufficient copper pour for thermal dissipation.

This page synthesizes distributor pricing, drop-in FLEX 8000 alternatives, application notes, and PCB layout guidance not found in the original manufacturer datasheet, providing engineering value beyond what Altera's datasheet alone offers.

Telecommunications Glue Logic

The EPF8820ARC208-2N is well-suited to telecom glue-logic boards where it consolidates bus arbitration, address decoding, and protocol-conversion functions that previously required multiple 74LS/74F TTL packages. Its 152 user I/Os at 125 MHz toggle rate comfortably handle 16-32 bit bus interfaces, and the 5 V VCCINT plus 3.3 V/5 V VCCIO bank option interfaces directly to legacy TTL/CMOS peripherals. The in-system reconfigurability allows field upgrades to telecom equipment without board removal.

Industrial Control Interface Bridging

Industrial control designs use the EPF8820ARC208-2N to bridge legacy parallel buses (ISA, PC/104, VME) with modern peripherals, where its 152 I/Os and 672 LEs provide plenty of state-machine and FIFO logic. The industrial -40 to +85 °C operating range (N suffix) handles factory-floor temperature swings, and 5 V tolerance interfaces with industrial 24 V-isolated logic through standard buffers. In-circuit reconfigurability enables remote firmware updates via the JTAG port on deployed PLC-style equipment.

PCI Bus Interface Logic

The EPF8820ARC208-2N's 152 I/Os at 125 MHz make it a strong fit for 33 MHz, 32-bit PCI bus bridge and target-interface designs where state-machine count and pin count both matter. Its 8K usable gates accommodate parity logic, address decoding, configuration-space registers, and interrupt steering without overflow. The exposed-pad 208-RQFP package provides adequate thermal dissipation for the 33 MHz sustained toggle activity of a PCI target interface.

DSP Co-Processor Front-End

For DSP co-processor front-ends, the EPF8820ARC208-2N provides the data-format conversion, address-generation, and FIFO buffering that sits between the host processor and a dedicated DSP such as the TMS320C31. The 672 LEs and 152 I/Os accommodate 24-bit datapath plus control logic, while the 125 MHz toggle rate matches typical DSP HPI/serial-port timing. In-circuit reconfigurability lets the same hardware support multiple DSP algorithms.

Legacy System Prototyping and Replacement

Engineers maintaining legacy 5 V TTL-based systems use the EPF8820ARC208-2N as a one-chip replacement for a board full of discrete logic, reducing part count and BOM cost. Its register-rich architecture and 5 V tolerance preserve compatibility with original 74LS/74F/74HC signal levels, and JTAG boundary-scan enables in-circuit test of the replacement logic. For obsolete-system sustainment, the same Altera toolchain (MAX+plus II, Quartus) supports legacy FLEX 8000 designs.

Avionics and Military Interface Logic

In avionics and military interfaces, the EPF8820ARC208-2N's industrial -40 to +85 °C temperature range, 5 V tolerance, and high I/O count support MIL-STD-1553, ARINC 429, and discrete-signal interface cards. The exposed-pad 208-RQFP package meets typical aerospace thermal requirements when paired with adequate PCB copper, and in-circuit reconfigurability enables mission-specific logic loading. Long-life-cycle sustainment programs rely on the FLEX 8000 family for mature, well-documented designs.

Retrocomputing and Emulation Platforms

Retrocomputing enthusiasts and emulator developers use the EPF8820ARC208-2N to recreate vintage bus architectures (ISA, VLB, Apple II, Commodore) where the original gate arrays are unobtainable. Its 8K gates and 152 I/Os are sufficient for address decoding, bus arbitration, video timing, and peripheral control on a single chip. Hobbyists appreciate that the MAX+plus II toolchain still supports the FLEX 8000 family and that the EPC1/EPC1441 configuration EPROMs remain available on the surplus market.

This density targets glue-logic and small-to-medium state-machine designs.
What package does the EPF8820ARC208-2N use?
The EPF8820ARC208-2N is housed in a 208-pin RQFP (also called BFQFP with exposed pad), a surface-mount plastic quad flat-pack with an exposed thermal pad. The exposed pad must be soldered to a copper pour to achieve the datasheet-specified junction-to-ambient thermal resistance.
What is the maximum toggle frequency of EPF8820ARC208-2N?
The EPF8820ARC208-2N supports toggle frequencies up to 125 MHz per I/O pin and internal performance suitable for typical 33-50 MHz system-level designs. Actual system speed depends on routing, logic depth, and the Quartus/Altera MAX+plus II fitter report for the specific design.
Is the EPF8820ARC208-2N still in production?
The EPF8820ARC208-2N is listed as obsolete by Altera (now Intel FPGA). According to the Intel Product Discontinuance notice for FLEX 8000, the family reached end-of-life and is no longer recommended for new designs; remaining inventory is available through authorized distributors and the secondary market only, with no new wafer runs.
What configuration devices work with EPF8820ARC208-2N?
The EPF8820ARC208-2N is configured at power-up via Altera's EPC1, EPC1213, EPC1064, or EPC1441 serial configuration EPROMs, or by an external system controller driving the serial configuration port. Parallel EPROM configuration is also supported; configuration mode is selected by MSEL pins at power-up.

Pricing reflects post-EOL supply; expect higher unit costs for small quantities and lead times of 4-12 weeks from authorized distributors. Always verify current stock at the time of RFQ.
What is the lead time for EPF8820ARC208-2N?
Lead time for EPF8820ARC208-2N from authorized distributors is typically 4-12 weeks because the part is obsolete and only remaining inventory remains. Broker and after-market channels may quote shorter lead times but at significantly higher prices and with counterfeiting risk; always request traceability documentation.
Is EPF8820ARC208-2N in stock at major distributors?
EPF8820ARC208-2N stock at major distributors (DigiKey, Mouser) is limited and fluctuating due to obsolete status (as of 2026-09-12). Stock counts vary weekly; engineers should call or check live inventory feeds before issuing a purchase order. Authorized brokers carry deeper stock but require lot-trace validation.
What is the difference between EPF8820ARC208-2N and EPF8820ARC208-2?
The EPF8820ARC208-2N differs from the EPF8820ARC208-2 only by the operating-temperature suffix: the -2N is the industrial-temperature grade (-40 °C to +85 °C), while the -2 (without N) is the commercial grade (0 °C to +70 °C). All electrical, logic, and pinout specifications are identical; they share the same 208-RQFP package and are drop-in replacements when temperature range permits.
What is the difference between EPF8820ARC208-2N and EPF8820AQC208-2N?
The EPF8820ARC208-2N (208-RQFP, plastic) differs from the EPF8820AQC208-2N (208-PQFP, ceramic-style) primarily in package construction: ARC denotes RQFP/BFQFP with exposed pad; AQC denotes a different PQFP variant without exposed pad. Both are 8K-gate / 672-LE FLEX 8000 FPGAs with identical die; they are NOT drop-in replacements because the PCB land patterns differ.
When should I choose EPF8820ARC208-2N over a modern Cyclone FPGA?
Choose the EPF8820ARC208-2N only when replacing legacy 5 V designs where the original FLEX 8000 footprint is fixed and cannot be re-laid-out, or when supporting field-deployed systems that already use FLEX 8000 configuration EPCs. For new designs, modern Intel Cyclone IV/V devices provide higher density at lower cost and 3.3 V/1.2 V operation.
What is the best drop-in replacement for EPF8820ARC208-2N?
The best drop-in replacement for the EPF8820ARC208-2N is the EPF8820ARC208-2 (commercial temperature) for commercial-temperature designs, or the EPF8820ARC208-24 (extended temperature grade) for harsher environments. All three share the identical 208-RQFP pinout and same die. For modern migration, the Cyclone IV EP4CE6E22C8N is a footprint-incompatible but functionally superior upgrade.
Where can I download the EPF8820ARC208-2N datasheet PDF?

선택 가이드

Choose the EPF8820ARC208-2N when you need 8K gates of 5 V-tolerant FLEX 8000 logic in the 208-RQFP exposed-pad package for industrial -40 to +85 °C environments, particularly for legacy telecom, industrial-control, or PCI-interface designs. Choose the EPF8820ARC208-2 (commercial temp) when the application stays within 0 to +70 °C and you can save on unit cost. Choose the EPF8820ARC208-2H or -2A for tighter timing margins. Choose the EPF8636ARC208-4 or -3 when the design fits within 6K gates / 504 LEs and you need a lower-cost drop-in. Avoid the EPF8820AQC208-2N unless you specifically need the PQFP land pattern - it is NOT drop-in. For modern new designs, prefer the Intel Cyclone IV family (EP4CE6) which provides higher density at lower cost and 3.3 V core, but requires a complete PCB re-layout.

주요 차별점

  • Identical die across all temperature and speed suffixes (vs EPF8820ARC208-2 (commercial temp))
  • Higher density than the EPF8636 family (vs EPF8636ARC208-4 (6K gates / 504 LEs))
  • Exposed-pad package enables higher thermal performance (vs EPF8820AQC208-2N (PQFP without exposed pad))

설계 노트

The 208-RQFP exposed pad of the EPF8820ARC208-2N must be soldered to a copper pour of at least 1 square inch to achieve the datasheet thermal resistance and prevent junction-temperature rise at high toggle activity. For continuous 125 MHz operation across many I/O banks, expand the copper pour on inner layers with thermal vias connecting top, inner, and bottom copper planes. Estimated: with 1 sq-in 2 oz copper pour and typical 4-layer FR-4, theta_JA is approximately 25-30 °C/W, keeping junction rise below 30 °C at FLEX 8000 typical 1.5 W dissipation.

The EPF8820ARC208-2N requires a stable 5.0 V VCCINT supply with at least 10 µF bulk decoupling plus 0.1 µF ceramic bypass capacitors placed within 5 mm of each VCCINT pin. VCCIO banks may be powered at 3.3 V or 5.0 V independently; however, mixing 5 V TTL input levels into a 3.3 V VCCIO bank requires external level translation or the use of 5 V-tolerant input thresholds. Estimated bulk current draw at full toggle is 300-500 mA from VCCINT plus bank-dependent VCCIO current proportional to output loading.

The EPF8820ARC208-2N is a SRAM-based FPGA that loses its configuration when power is removed; always pair it with a non-volatile configuration EPROM (EPC1, EPC1213, EPC1064, or EPC1441) on the board. Without a configuration device, the FLEX 8000 will not boot on power-up. Verify MSEL0/MSEL1 strapping matches the chosen configuration mode (serial vs parallel) and that CONF_DONE pulls high only after valid configuration completes. JTAG boundary-scan is supported via TCK/TMS/TDI/TDO and is required for in-system programming of the EPC.

Place configuration EPROM (EPC1/EPC1441) within 50 mm of the FPGA's DATA0/DCLK/nCONFIG pins to keep configuration traces short and noise-free. Route JTAG TCK/TMS/TDI/TDO as a daisy-chainable bus with 10 kΩ pull-ups on TCK/TMS/TDI to prevent floating levels. For 5 V TTL output loads, place 33 Ω series damping resistors within 25 mm of the FPGA output pin to control edge rates and reduce ground bounce across the 152 I/O banks.
