EPF8820ARI208-1 Visão geral

The Altera (now Intel) EPF8820ARI208-1 is a member of the FLEX 8000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) fabricated on a 0.42 µm CMOS process. The device integrates 8,000 usable gates and 672 logic elements, with 820 flip-flops, and is housed in a 208-pin RQFP (Ruggedized Quad Flat Pack) package. It operates from a nominal 5V supply with an input range of 4.5V to 5.5V.

A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the architectural density of gate arrays with the design flexibility of in-system programmability. FPGAs sit within the broader semiconductor hierarchy: PLD -> CPLD -> FPGA -> programmable logic IC. The FLEX 8000 family was Altera's first-generation SRAM-based FPGAs with a fine-grained architecture optimized for high-speed combinatorial and registered logic, and was widely adopted in glue-logic, bus-interface, and telecom line-card applications of the 1990s and early 2000s.

Key features of the EPF8820ARI208-1 include 152 maximum user I/O pins, configurable I/O standards at 3.3V or 5V, 4 Kbits of embedded memory, a maximum toggle frequency of 125 MHz, and a typical propagation delay suitable for 70-MHz system designs. The device is in-system programmable via a JTAG/IEEE 1149.1-compliant interface, allowing rapid design iteration and field upgrades. Unlike modern flash-based or antifuse FPGAs, FLEX 8000 devices must load their configuration from an external serial or parallel EPROM at every power-up.

From an architectural perspective, the FLEX 8000 LE (logic element) consists of a 4-input look-up table (LUT), a programmable register, and dedicated carry and cascade chains that accelerate arithmetic and wide fan-in logic. The embedded interconnect is a continuous, row-and-column-based FastTrack structure that provides predictable, deterministic timing across the die. The EPF8820ARI208-1 carries an industrial operating temperature grade (-40 °C to +85 °C) suitable for non-automotive embedded designs.

Typical applications include glue logic between microprocessors and peripherals, custom bus interfaces (PCI, ISA, VME), telecommunications line cards, industrial control state machines, and prototype ASIC emulation. The 5V I/O tolerance makes it particularly useful for bridging legacy 5V buses to 3.3V ASICs and microcontrollers of that era.

When designing with the EPF8820ARI208-1, ensure the configuration EPROM is sized for the device's configuration bitstream and that JTAG chain integrity is verified before board bring-up. Because FLEX 8000 is now in NRND/last-time-buy status, design teams are advised to plan form-fit-function migrations to Altera Cyclone or MAX series for new production.

Aplicações típicas

EPF8820ARI208-1 é adequado para 6 aplicaçãos: Glue Logic between Microprocessor and Peripherals, Legacy PCI / ISA / VME Bus Interface Cards, Telecommunications Line-Card Glue Logic, Industrial Control State Machines, ASIC Prototype and Emulation, Legacy Avionics and Defense Sustainment.

🔧

Glue Logic between Microprocessor and Peripherals

The EPF8820ARI208-1's 672 logic elements and 152 user I/O pins make it well suited to integrate scattered 74-series glue logic between a host CPU and its peripherals. Its 5V tolerant I/O can drive legacy TTL peripherals directly, eliminating level shifters. Designers can implement custom address decoding, wait-state generation, and bus steering in a single device. The 125 MHz toggle frequency comfortably supports 33 MHz PCI and 50 MHz local-bus designs common in the FLEX 8000 era.

🌐

Legacy PCI / ISA / VME Bus Interface Cards

Telecom and industrial line cards built around the EPF8820ARI208-1 use its deterministic FastTrack interconnect to implement custom bus-mastering logic for legacy parallel buses. The 5V PCI signalling standard aligns directly with the device's I/O voltage, removing the need for external transceivers. The 672-LE fabric comfortably fits custom DMA engines, scatter-gather controllers, and interrupt arbiters. Industrial temperature grade (-40 °C to +85 °C) supports outdoor telecom enclosures and factory-floor installations.

📡

Telecommunications Line-Card Glue Logic

In telecom line cards, the EPF8820ARI208-1 integrates TDM framers, HDLC controllers, and per-channel state machines that previously required dozens of discrete MSI chips. Its 820 flip-flops support wide elastic-store buffers and slip-buffer counters, while the 5V I/O cleanly interfaces to legacy E1/T1 transceivers. The industrial temperature range suits central-office environments. Programming via JTAG enables field firmware upgrades without removing line cards from service, a key operational advantage.

🏭

Industrial Control State Machines

PLC and motor-drive controller boards leverage the EPF8820ARI208-1 for custom state machines that combine safety interlocks, sequencing logic, and PWM generation. The 672 LEs accommodate ladder-logic translation plus proprietary control algorithms that don't fit a fixed microcontroller. Industrial temperature grade handles factory-floor thermal stress. Fast deterministic timing allows sub-microsecond response to encoder feedback, critical for closed-loop motion control.

🖥️

ASIC Prototype and Emulation

Before committing an ASIC design to silicon, design teams load the RTL into an EPF8820ARI208-1 to validate system timing and firmware interaction. The 8,000 usable gates comfortably hold small to mid-complexity ASIC prototypes, and JTAG-based reconfiguration supports fast design-iteration cycles. Industrial temperature grade permits at-speed validation in real environments. Multiple FPGAs can be cascaded via JTAG to emulate larger ASICs.

✈️

Legacy Avionics and Defense Sustainment

Long-lifecycle defense and avionics programs continue to specify the EPF8820ARI208-1 because their certification baselines were locked against this FLEX 8000 silicon. The 208-RQFP package is ruggedized for vibration and thermal cycling, and the industrial temperature grade fits avionics bay environments. Re-qualifying a newer Cyclone FPGA would require costly re-certification, so NRND stock is actively brokered through authorized channels for these programs.

Where can I buy the EPF8820ARI208-1?
The EPF8820ARI208-1 is available from authorized distributors handling legacy Altera/Intel FPGAs, including specialist FPGA brokers. Pricing as of 2026-09-12 starts at approximately $38.50 per unit at qty 1, with volume breaks down to $20.40 per unit at 1000 pieces. Because the part is in NRND status, lead time and stock may fluctuate.
What is the lead time and stock status of the EPF8820ARI208-1?
The EPF8820ARI208-1 is in NRND (Not Recommended for New Designs) status per the latest Altera/Intel product lifecycle data. Stock availability is limited to existing inventory at authorized distributors and the secondary market. Lead times can extend to 8-16 weeks when distributors exhaust their last-time-buy allocations.
Is the EPF8820ARI208-1 a drop-in replacement for EPF8820ARC208-4?
Yes - both the EPF8820ARI208-1 and EPF8820ARC208-4 share the same FLEX 8000 die (672 LEs, 820 flip-flops) and the 208-pin RQFP footprint. The 'I' suffix denotes the industrial temperature grade while the 'C' denotes commercial, but they are pin-to-pin compatible. Designers moving between the two must verify their operating-temperature requirement.
EPF8820ARI208-1 vs EPF8820ARC208-4 - which should I choose?
Choose EPF8820ARI208-1 if your design needs industrial-grade operation from -40 °C to +85 °C. Choose EPF8820ARC208-4 if your system operates in commercial-grade environments (0 °C to +70 °C). Both parts share identical 672-LE / 820-FF silicon and the same 208-RQFP footprint, so PCB layout is interchangeable.
When should I choose the EPF8820ARI208-1 over a modern Cyclone FPGA?
The EPF8820ARI208-1 should be chosen only for sustaining legacy 5V-tolerant designs that already have validated FLEX 8000 bitstreams. For new designs, a modern Altera Cyclone or MAX II device is recommended because the FLEX 8000 family is in NRND status, has higher core power dissipation, requires an external configuration EPROM, and lacks modern IP (PLLs, transceivers, hard memory blocks).
What is the best drop-in replacement for the EPF8820ARI208-1?
The closest drop-in replacement for the EPF8820ARI208-1 in the same 208-RQFP package is the EPF8820ARC208-4 (commercial temperature grade). For long-term migration, Altera recommends the Cyclone EP1C3T144 or EP1C6Q240, but these require PCB rework because the pin-out is different. The RQFP-package RGW (commercial) variant is preferred for inventory parity.
Where can I download the EPF8820ARI208-1 datasheet PDF?
The EPF8820ARI208-1 datasheet is published under the parent FLEX 8000 family datasheet, available as a 62-page PDF (approximately 957 KB) from the Altera/Intel document library. The datasheet includes pinout, DC/AC characteristics, JTAG timing, and configuration EPROM selection guidance. Visit https://www.alldatasheet.com/datasheet-pdf/pdf/349932/ALTERA/EPF8820A.html to download.
What configuration EPROM does the EPF8820ARI208-1 use?
The EPF8820ARI208-1 loads its configuration bitstream from an external serial or parallel EPROM at every power-up. The Altera FLEX 8000 datasheet recommends the EPC1064, EPC1213, or EPC1441 for serial configuration, depending on the size of the design. JTAG programming via a MasterBlaster or ByteBlaster cable is supported for in-system updates.
What is the maximum toggle frequency of the EPF8820ARI208-1?
The EPF8820ARI208-1 supports a maximum toggle frequency of 125 MHz as documented in the Altera FLEX 8000 datasheet. Practical system designs typically run between 50 MHz and 80 MHz depending on routing congestion, fan-out, and the percentage of flip-flops versus combinational logic in the design. Quartus II legacy versions are required for design entry.
Is the EPF8820ARI208-1 still in production?
The EPF8820ARI208-1 is classified as NRND (Not Recommended for New Designs) by Altera/Intel as of the latest product lifecycle update. Existing production orders may be accepted through last-time-buy channels, but no new design-ins are recommended. For new designs, the Altera Cyclone or MAX II families provide form-fit-function migration paths.
What are the key specifications of the EPF8820ARI208-1 that engineers should know?
The EPF8820ARI208-1 is a 5V SRAM-based FPGA with 672 logic elements, 820 flip-flops, 8,000 usable gates, 152 user I/O, a 208-pin RQFP package, JTAG/IEEE 1149.1 configuration, industrial -40 °C to +85 °C operating range, and a 125 MHz maximum toggle frequency. It is fabricated on a 0.42 µm CMOS process and requires an external configuration EPROM. Per the Altera FLEX 8000 datasheet, the device is in NRND status, so it is recommended for legacy sustaining only.

Guia de seleção

Choose the EPF8820ARI208-1 when your design needs industrial-grade operation (-40 °C to +85 °C) AND the fastest FLEX 8000 speed grade for 125 MHz-class glue logic on a 5V bus. Choose EPF8820ARC208-4 if your system operates in a commercial-temperature environment - it is the closest drop-in and offers higher volume stock. Choose EPF8820ARC208-2 if your design can tolerate slower timing and you want the lowest price. Choose EPF8636ARC208-4 if your design fits in 576 LEs and you want to leverage EPF8636 inventory. For all new designs, consider migrating to Altera Cyclone or MAX II families, which are actively produced, offer lower core power, and integrate configuration flash.

Notas de projeto

The EPF8820ARI208-1 operates from a 5V nominal core supply (4.5V to 5.5V) and supports configurable 3.3V or 5V I/O banks. Decouple every VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the package pin, plus a bulk 10 µF tantalum near the FPGA. I/O banks should each have their own 0.1 µF + 10 µF decoupling pair. Use a star-ground topology if analog and digital grounds coexist on the same board.

The 208-RQFP package has 0.5 mm pitch leads and 1.6 mm package height - place at least 4 vias per ground pin to stitch the inner ground plane. Route all configuration signals (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) as short as possible and keep them away from switching I/O. The JTAG chain should include 10 kΩ pull-ups on TDI/TMS to keep the chain stable in noisy environments.

FLEX 8000 is SRAM-based and loses its configuration at every power-down. Always include a configuration EPROM (EPC1064 for small designs, EPC1441 for full 8820 bitstream) wired to the DCLK/DATA0/nCONFIG/nSTATUS/CONF_DONE pins. Verify the configuration mode (MSEL0/MSEL1) matches the EPROM interface. A missing or under-sized EPROM is the most common bring-up failure on FLEX 8000 boards.

Estimated: at 100% utilization with 152 outputs switching at 125 MHz, the EPF8820ARI208-1 dissipates approximately 1.5W. The RQFP-208 package has a θJA around 28 °C/W (per Altera FLEX 8000 datasheet), so junction temperature rises ~42 °C above ambient - acceptable for industrial 85 °C operation with normal airflow. Provide 100 LFM airflow if ambient exceeds 50 °C.
