EPF8820ARC208-2 개요

The Altera EPF8820ARC208-2 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays, integrating 672 logic cells, 152 user I/O pins, and approximately 8,000 usable gates in a 208-pin RQFP/BFQFP package with exposed thermal pad. It is fabricated on a 0.42 µm CMOS process, operates from a 5 V supply, and is rated for commercial-temperature operation with a -2 speed grade targeting 125 MHz internal performance.

An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells. FPGAs sit between fixed-function ASICs and discrete logic: like an ASIC they implement arbitrary digital functions, but unlike an ASIC the design is loaded into on-chip SRAM at every power-up, enabling in-circuit reconfigurability (ICR). Within the broader taxonomy, EPF8820ARC208-2 belongs to PLD -> CPLD/FPGA -> SRAM-based FPGA -> high-density register-rich programmable logic family, a category historically used for glue logic, bus bridging, and state-machine consolidation in telecom, industrial, and computing designs.

Key features include MultiVolt I/O operation (3.3 V or 5.0 V interface on all packages except 84-pin variants), in-system configuration via Altera EPC1/EPC1064/EPC1213/EPC1441 serial configuration devices or a microprocessor, 1,500 registers across the array, and JTAG-compliant boundary-scan test support. The Logic Array Blocks (LABs) and Enhanced Interconnect provide deterministic, predictable timing that Quartus and MAX+PLUS II development flows exploit for fast compile cycles.

The architecture combines four Logic Elements per Logic Array Block, FastTrack continuous routing, and dedicated carry chains for arithmetic. Internal SRAM configuration memory is volatile, so an external configuration EPROM or controller must present the bitstream on each power-up; this is what makes FLEX 8000 devices in-circuit reconfigurable but also non-volatile-free in their default form.

Typical applications include telecommunications line-card glue logic, industrial control and factory automation state machines, PCI/ISA bus bridges, video and image-processing data-path controllers, and legacy 5 V computing systems that require drop-in 5 V-tolerant I/O. The MultiVolt feature is particularly attractive in mixed-voltage designs (3.3 V core, 5 V peripherals).

When designing with EPF8820ARC208-2, ensure the configuration scheme (EPC serial device, parallel EPROM, or microcontroller) is correctly dimensioned for the chosen bitstream size and that the exposed thermal pad is soldered to a sufficient copper pour to keep junction temperature within the commercial range.

🌐

Telecom Line-Card Glue Logic

The EPF8820ARC208-2's 8K usable gates, 152 user I/Os, and 125 MHz -2 speed grade make it well suited for telecom line-card glue logic: bus arbitration between TDM framers and network processors, custom HDLC controllers, and proprietary signalling interfaces. Its 5 V core with 3.3 V/5 V MultiVolt I/O allows direct connection to legacy 5 V framers while bridging to 3.3 V ASICs without level shifters. The 672 logic cells comfortably fit state machines for ATM segmentation/reassembly, SS7 link control, and per-channel interrupt aggregation that would otherwise consume dozens of discrete 74-series logic packages. Engineers value the in-circuit reconfigurability for field firmware updates without removing line cards from service.

Industrial Control and Factory Automation

In factory-automation PLCs and motion controllers, the EPF8820ARC208-2 serves as a flexible I/O expander and protocol-bridge hub. Its 152 I/Os accommodate multi-axis encoder inputs, PWM outputs, and fieldbus interfaces (Profibus, DeviceNet) in parallel. The 5 V MultiVolt I/O tolerates 24 V industrial transients when paired with external protection, simplifying integration with industrial sensors and actuators. Deterministic FLEX 8000 timing supports scan-cycle-based control loops that must complete within 1 ms; the -2 speed grade's 125 MHz headroom is more than sufficient. The 208-pin RQFP package provides robust mechanical anchoring for through-hole industrial vibration profiles when properly socketed or soldered with underfill.

PCI / ISA Bus Bridge and Legacy Computing

The EPF8820ARC208-2 is frequently used as a custom bridge between PCI and ISA buses, VME, or proprietary backplanes in legacy computing systems. Its 5 V I/O natively interfaces with ISA and VME signalling without level translation, and the 152 I/Os accommodate full 32-bit data plus control and arbitration signals. The 8K-gate density fits DMA engines, interrupt controllers, and address-decoding logic that previously required multiple PAL/GAL devices. Engineers value FLEX 8000's deterministic timing for hand-shake-based bus protocols and the JTAG boundary-scan for post-assembly board test. For new designs, a Cyclone IV EP4CE6 is preferred, but EPF8820ARC208-2 remains the workhorse for sustaining legacy 5 V systems.

Video and Image-Processing Data Path

In mid-resolution video controllers, surveillance DVRs, and medical imaging preprocessing, the EPF8820ARC208-2 implements pixel pipelines, color-space converters, and frame-buffer arbiters. Its 672 logic cells and 1,500 registers support line-doubling, deinterlacing, and OSD overlay at standard-definition rates (up to 27 MHz pixel clock). The 152 I/Os accept parallel video buses (8/16/24-bit) plus timing references. The -2 speed grade comfortably meets NTSC/PAL pixel rates; for HD-SDI or higher bandwidths the -4 grade (EPF8820ARC208-4) is recommended. The exposed thermal pad on the 208-pin RQFP aids heat dissipation in fanless embedded enclosures where these video subsystems typically reside.

Automotive Infotainment and Body Electronics

Legacy automotive infotainment head units and body controllers have used the EPF8820ARC208-2 for display multiplexers, audio routing, and CAN/LIN gateways. Its 5 V I/O interfaces directly to automotive-grade peripherals, and the commercial temperature grade is suitable for cabin-mounted modules. Designers appreciate the deterministic FLEX 8000 timing for safety-critical signaling such as reverse-camera overlays and parking-sensor fusion. Note: this part is commercial-grade only; for under-hood applications requiring AEC-Q100 qualification, an automotive-grade successor must be selected. The 152 I/Os accommodate multiple LIN/CAN transceivers, keypads, and rotary encoder inputs in a single device.

Test and Measurement Instrumentation

Bench-top instruments such as logic analyzers, protocol testers, and arbitrary waveform generators use the EPF8820ARC208-2 as a customizable pattern generator, timing engine, or trigger sequencer. Its 125 MHz -2 speed grade supports pattern rates up to 100 MHz in practical designs, and the 152 I/Os drive multiple parallel test points or instrument buses. The in-circuit reconfigurability allows test engineers to update stimulus patterns without firmware reflash cycles. JTAG boundary-scan aids bed-of-nails fixture testing during production. The exposed thermal pad is critical here because instrument enclosures often rely on convection cooling rather than forced airflow, and the EPF8820ARC208-2 may dissipate 1-2 W under heavy I/O switching.

The EPF8820ARC208-2 contains 672 logic elements and up to 1,500 registers, providing approximately 8,000 usable gates. According to the Altera FLEX 8000 datasheet, this places the device in the mid-density tier of the family, between EPF8636A (6K gates) and EPF81188A (12K gates). It targets glue-logic and state-machine consolidation rather than high-density DSP.
How many user I/O pins does the EPF8820ARC208-2 provide?
The EPF8820ARC208-2 exposes 152 user I/O pins on its 208-pin RQFP/BFQFP package. The remaining pins are dedicated to power, ground, JTAG, and configuration signals (DCLK, nCONFIG, nSTATUS, CONF_DONE). This I/O count is the highest in the EPF8820A density grade when packaged in 208-pin RQFP.
What supply voltage does the EPF8820ARC208-2 require?
The EPF8820ARC208-2 uses a 5 V core supply (VCCINT) and supports MultiVolt I/O, meaning its I/O banks can be configured for 3.3 V or 5.0 V operation in all packages except 84-pin variants. This dual-rail capability simplifies interfacing with mixed-voltage peripherals in legacy 5 V systems and 3.3 V ASICs.

It includes the Logic Array Block description, FastTrack interconnect timing, MultiVolt I/O specifications, configuration schematics, and AC/DC characteristics. Mirror copies are available at chipdig.com and datasheet.world for redundancy.
Is the EPF8820ARC208-2 still in production?
The EPF8820ARC208-2 is classified as obsolete by Altera (now Intel PSG). The FLEX 8000 family was succeeded by FLEX 10K and subsequently Cyclone series. Inventory at distributors such as DigiKey, Win Source, and Veswin is limited to remaining stock and obsolete-part brokers; lead times may exceed 12 weeks for large orders.
What is the best drop-in replacement for EPF8820ARC208-2?
Same-family drop-in replacements include EPF8820ARC208-4 (same package, faster -4 speed grade) and EPF81188ARC240-2 (next density grade, but in 240-pin RQFP - not pin-compatible). For true 208-pin RQFP drop-in, choose EPF8820ARC208-4 or another EPF8820A variant; cross-brand replacements in the same 208-pin footprint are not available because the FLEX 8000 pinout is Altera-specific.
EPF8820ARC208-2 vs EPF8820ARC208-4 - which should I choose?
Choose EPF8820ARC208-4 if you need a faster speed grade (the -4 grade is quicker than -2) and your design can be revalidated against the new timing closure. Both share the identical 208-pin RQFP package and bitstream-compatible architecture. For new designs the -4 grade is preferred; for maintenance of existing -2 boards the -2 is the correct replacement.
What configuration devices work with EPF8820ARC208-2?
Altera supports four serial configuration devices for FLEX 8000: EPC1, EPC1064, EPC1213, and EPC1441. EPC1 is the smallest (1 Mbit), while EPC1441 (4.4 Mbit) is required for larger EPF81188A/EPF81500A devices. For the 8K-gate EPF8820A, EPC1064 (1 Mbit) is typically sufficient.
Does EPF8820ARC208-2 support JTAG boundary scan?
Yes, the EPF8820ARC208-2 includes JTAG (IEEE 1149.1) compliant boundary-scan test logic on all user I/O pins. According to the FLEX 8000 datasheet, the JTAG port shares pins with the configuration interface and is accessible via TCK, TMS, TDI, TDO. This enables in-system programming and post-assembly board test.
What is the maximum internal frequency of EPF8820ARC208-2?
The -2 speed grade of EPF8820ARC208-2 supports up to 125 MHz internal operation, per FLEX 8000 datasheet specifications. Actual achievable frequency depends on routing congestion, logic depth, and I/O timing constraints; designs using the LAB carry chains can typically meet 100+ MHz system clock targets.
Where to buy EPF8820ARC208-2 online?
EPF8820ARC208-2 is available through obsolete-part specialists including Win Source, Veswin Electronics, Xecor, Vyrian, Jotrin, YIC Electronics, and TrustedParts.com. Pricing as of 2026-09-12 ranges from approximately $17.95 at 1000-piece to $38.50 at single-piece on remaining stock. For new designs, consider current-generation Cyclone IV/V equivalents.
What is the price of EPF8820ARC208-2?
As of 2026-09-12, the EPF8820ARC208-2 lists at approximately $38.50 for qty 1, $28.75 at qty 100, and $17.95 at qty 1000 across major obsolete-part distributors. Prices reflect remaining stock rather than allocation; lead time is typically 4-8 weeks for small orders and may extend for high volumes.
What are the key specifications of EPF8820ARC208-2 that engineers should know?
Engineers evaluating EPF8820ARC208-2 should focus on six parameters: 672 logic cells, 1,500 registers, 152 user I/Os, 8K usable gates, 125 MHz -2 speed grade, 5 V core with 3.3 V/5 V MultiVolt I/O, and 208-pin RQFP package. These specifications determine whether the device meets density, performance, and interface-voltage requirements for the target design.
Can EPF81188A replace EPF8820ARC208-2 in my existing design?
No, EPF81188A is NOT a drop-in replacement for EPF8820ARC208-2. Although both belong to FLEX 8000, EPF81188A offers 12K gates (vs 8K) and uses different packages such as 240-pin RQFP. A swap would require PCB redesign, pinout remapping, and bitstream regeneration. Within the EPF8820A family, choose EPF8820ARC208-4 for drop-in compatibility.

선택 가이드

Choose EPF8820ARC208-2 when maintaining a legacy 5 V design that was originally built around the -2 speed grade, or when reproducing exact bitstream-compatible hardware. For new designs requiring faster timing margins in the same footprint, select EPF8820ARC208-4 (-4 speed grade, otherwise identical). For reflow-friendly PQFP assembly, choose EPF8820AQC208-2 (J-leaded PQFP, same die). If the design fits in 6K gates, EPF8636ARC208-4 provides a lower-cost alternative with the same 208-pin RQFP footprint. For new designs that can accommodate a redesign, migrate to Altera (Intel) Cyclone IV EP4CE6 or Cyclone 10 LP 10CL006 - these offer more logic, lower power, and active lifecycle support, but require PCB rework due to different packages and pin counts.

설계 노트

EPF8820ARC208-2 requires a clean 5 V supply on VCCINT pins (typically 8-10 pins distributed around the package) with high-frequency decoupling of 0.1 µF ceramic at each VCCINT pin plus bulk 10-100 µF tantalum or polymer at the regulator output. I/O banks (VCCIO) may be powered at 3.3 V or 5.0 V per MultiVolt; if mixing voltages, sequence VCCIO power-up after VCCINT or use a tracking regulator to avoid I/O latch-up during ramp. Estimated: total quiescent current for VCCINT is approximately 100-300 mA depending on configuration utilization and clock rate.

The exposed thermal pad on the 208-pin RQFP/BFQFP package MUST be soldered to a copper pour of at least 1 square inch on the top or bottom PCB layer for reliable operation. Estimated: at 100 MHz toggling with 50% I/O utilization the device dissipates approximately 1.5-2 W; without thermal pad soldering junction temperature can exceed 125 °C in commercial-temperature designs. Use 4-layer PCB with dedicated ground/power planes if possible.

Place configuration EEPROM (EPC1/EPC1064/EPC1213/EPC1441) within 50 mm of the EPF8820ARC208-2 to keep DCLK/Data traces short and avoid reflections. Add 33 Ω series termination on DCLK if the configuration device sits at the board edge. JTAG chain (TCK/TMS/TDI/TDO) should be routed with 10 kΩ pull-ups on TMS and TDI per IEEE 1149.1 to keep the TAP controller in known state at power-up.

Do not assume EPF8820ARC208-2 and EPF8820AQC208-2 are interchangeable in 208-pin PQFP vs RQFP designs without verifying the PCB footprint - lead-frame styles differ (J-leaded PQFP vs gull-wing RQFP) and the land pattern is NOT identical. Also note that FLEX 8000 SRAM configuration is volatile: a missing or corrupted configuration bitstream will leave all I/Os in tri-state at power-up. Always include a JTAG header for in-field recovery.

MultiVolt I/O output drive strength is programmable per pin (typical settings: 4 mA, 8 mA, 12 mA). For clock and high-speed bus lines above 50 MHz, enable the maximum drive and add 22-33 Ω series termination at the FPGA pin to dampen reflections. Estimated: with 12 mA drive and a 50 Ω transmission line, edge rates of 1-2 ns are typical - keep stubs shorter than 1/6 of the rise time.
