EPF8820ARI208-3 Обзор

The Altera (Intel) EPF8820ARI208-3 is a member of the FLEX 8000 family of CMOS Field-Programmable Gate Arrays (FPGAs), delivering 672 logic elements (LEs) in a 208-pin Plastic Quad Flat Pack (PQFP/RQFP) package with industrial-grade temperature rating. The device integrates 152 user I/O lines plus 4 dedicated inputs, supports configurable I/O standards at 3.3 V or 5 V, and reaches a maximum internal clock frequency of 385 MHz.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that allows designers to configure arbitrary digital logic after manufacturing using a combination of look-up tables (LUTs), programmable interconnect, and I/O cells. FPGAs sit within the semiconductor hierarchy as: programmable logic -> logic IC -> integrated circuit -> semiconductor. The FLEX 8000 family was Altera's first-generation fine-grained SRAM-based FPGA architecture, predating modern Cyclone and Stratix families, and remains in service in long-lifecycle industrial, telecom, and legacy aerospace designs.

Key architectural features include 672 logic elements, 152 user I/O, configurable I/O voltage (3.3 V or 5 V), 385 MHz maximum clock frequency, and SRAM-based configuration cells requiring external configuration memory. The -3 speed grade indicates a specific FLEX 8000 timing bin, and the 'I' suffix denotes the industrial temperature range. Unlike modern flash- or antifuse-based FPGAs, FLEX 8000 devices must be reconfigured on every power-up via a serial configuration EPROM or microcontroller.

Typical applications include industrial control logic, telecom interface glue logic, legacy PCI bridge designs, peripheral bus controllers, and long-lifecycle embedded systems where re-spinning the FPGA is impractical. The 5 V tolerance on I/O is particularly valuable for interfacing to legacy TTL buses.

When designing with this device, note that FLEX 8000 devices are now NRND/EOL - plan for migration to Cyclone II/III/V or similar modern Altera/Intel FPGAs for new designs. Programming requires Altera MAX+PLUS II or Quartus (legacy support mode) plus a configuration device such as EPC1 or EPC2.

This page synthesizes distributor stock, drop-in same-package alternatives from the FLEX 8000 family, and practical migration guidance not found in the original datasheet.

Типичное применение

EPF8820ARI208-3 подходит для 6 применениеs: Industrial Control Logic, Telecom Interface Glue Logic, Legacy PCI Bridge Designs, Peripheral Bus Controllers, Medical Imaging Front-End Logic, Test and Measurement Instrumentation.

🏭

Industrial Control Logic

The EPF8820ARI208-3's 672 logic elements and 152 user I/O pins provide sufficient capacity for medium-complexity industrial control state machines, including PLC logic replacement, motor control sequencing, and sensor fusion pre-processing. Its 3.3 V / 5 V configurable I/O allows direct interfacing to legacy 5 V TTL industrial buses, optocouplers, and 24 V industrial transceivers with simple resistive level shifting. The industrial temperature rating (-40C to +85C) ensures reliable operation in factory floor enclosures and outdoor equipment. The 385 MHz maximum clock frequency is more than adequate for deterministic control loops at sub-microsecond latency. Long-lifecycle FLEX 8000 silicon availability through brokers enables 10-15 year production runs for industrial OEMs that cannot re-spin their FPGA design.

🌐

Telecom Interface Glue Logic

The EPF8820ARI208-3 is well suited as glue logic between legacy telecom ASICs, T1/E1 framer chips, and backplane transceivers where deterministic low-latency bus conversion is required. With 152 user I/O, the device can implement multiple parallel protocol converters (e.g., UTOPIA to PCM, HDLC to FIFO) in a single chip, reducing board area. Its 5 V tolerant I/O directly interfaces to legacy telecom line interface units that operate at 5 V TTL levels, eliminating level shifters. The 208-pin PQFP package with 0.5 mm pitch accommodates high I/O count designs while remaining hand-solderable for low-volume repair. FPGAs in this role are commonly deployed in central-office equipment with 15-20 year deployment cycles.

🖥️

Legacy PCI Bridge Designs

The EPF8820ARI208-3 is widely deployed as a custom PCI bridge in legacy PC and embedded systems, implementing 33 MHz PCI target or master interfaces and protocol translation between PCI and local processor buses. The 672 LE capacity comfortably fits a 32-bit PCI target with FIFOs and address decoding, while 152 I/O pins allow direct connection to the PCI bus plus local processor data, address, and control signals. The 5 V tolerant I/O is critical for PCI 5 V signaling environments. The -3 speed grade meets 33 MHz PCI timing closure requirements with margin. Migration to PCI Express requires a redesign, but the FLEX 8000 family remains in production for legacy PCI-based systems in industrial PCs and medical imaging equipment.

Peripheral Bus Controllers

The EPF8820ARI208-3 implements custom peripheral bus controllers such as ISA-to-local-bus bridges, VME bus interfaces, and proprietary backplane controllers in aerospace and defense subsystems. Its 152 I/O pins can directly drive multi-byte parallel data buses plus address and control signals, while the 672 LEs accommodate state machines for bus arbitration and protocol sequencing. The industrial temperature grade supports deployment in avionics bays and ground vehicle electronics. The FLEX 8000 family has extensive flight heritage in military and aerospace systems, and qualification data exists for many legacy defense platforms. Long-term broker availability supports 20+ year sustainment programs typical in this segment.

What is the EPF8820ARI208-3?

The EPF8820ARI208-3 is a member of Altera's FLEX 8000 family of SRAM-based Field-Programmable Gate Arrays, featuring 672 logic elements, 152 user I/O pins, and a 208-pin PQFP package. According to the manufacturer datasheet, it operates at a maximum internal clock frequency of 385 MHz and supports 3.3 V or 5 V configurable I/O standards, making it suitable for interfacing with legacy TTL systems.

Is the EPF8820ARI208-3 still in production?

The EPF8820ARI208-3 is classified as Not Recommended for New Designs (NRND). Altera/Intel continues limited production for legacy maintenance, but the FLEX 8000 family has been superseded by Cyclone and MAX series FPGAs. New designs should target Cyclone II/III/V equivalents, and the part is best reserved for sustaining existing long-lifecycle products.

How many logic elements does the EPF8820ARI208-3 have?

The EPF8820ARI208-3 integrates 672 logic elements (LEs). FLEX 8000 LEs each contain a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade logic. For perspective, this is roughly equivalent in capacity to a small Cyclone II EP2C5 device, but with significantly lower performance and higher static power consumption.

What package does the EPF8820ARI208-3 use?

The EPF8820ARI208-3 is housed in a 208-pin Plastic Quad Flat Pack (PQFP) with gull-wing leads, package code HFQFP. The PQFP208 has a body size of approximately 28 mm x 28 mm with 0.5 mm lead pitch. It is a surface-mount package and requires careful thermal management under high-utilization workloads.

What is the difference between EPF8820ARI208-3 and EPF8820ARC208-3?

Is EPF8820ARI208-3 the same as EPF8820A?

Yes - the EPF8820ARI208-3 is a specific orderable part number within the broader EPF8820A die family. The 'ARI208' suffix specifies the 208-pin Industrial PQFP package, and '-3' is the speed grade. The base EPF8820A designation refers to the underlying silicon, which is also offered in multiple package and temperature variants within the FLEX 8000 family.

Can EPF8820ARC208-3 replace EPF8820ARI208-3?

Yes, the EPF8820ARC208-3 is a drop-in replacement for the EPF8820ARI208-3 on the same 208-pin PQFP footprint, with the only difference being temperature grade (commercial 0C to +70C vs industrial -40C to +85C). For designs requiring industrial-grade operation across the full -40C to +85C range, the 'I' variant must be retained; for benign thermal environments, the 'C' variant is fully pin-compatible.

What is the best drop-in replacement for EPF8820ARI208-3?

The best drop-in replacements for the EPF8820ARI208-3 within the FLEX 8000 family on the same 208-pin PQFP footprint are EPF8820ARC208-3 (commercial temp grade, identical silicon) and EPF8820AQC208-3 (208-pin QFP variant). All three share the same 672 logic elements and pin-out; selection is driven by temperature range and package code preference.

Where to download the EPF8820ARI208-3 datasheet PDF?

The EPF8820ARI208-3 datasheet is available as part of the EPF8820A family datasheet on Alldatasheet (https://www.alldatasheet.com/datasheet-pdf/pdf/95316/ALTERA/EPF8820A.html). The full FLEX 8000 family datasheet documents the EPF8820A die architecture, package options, electrical characteristics, and timing specifications across all speed grades.

Where can I find the EPF8820ARI208-3 pinout?

The EPF8820ARI208-3 pinout for the 208-pin PQFP package is documented in the FLEX 8000 family datasheet. Pin assignments include 152 user I/O pins distributed across the package perimeter, 4 dedicated inputs, dedicated JTAG pins (TDI, TDO, TMS, TCK), configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0), power (VCCINT, VCCIO) and ground (GND) pins.

What is the difference between EPF8820ARI208-3 and EPF8820ARC208-4?

The EPF8820ARI208-3 is speed grade -3 in the industrial 208-pin PQFP, while EPF8820ARC208-4 is the faster speed grade -4 in the commercial 208-pin PQFP. The -4 grade offers higher maximum clock frequency than -3 within the FLEX 8000 family. Both share 672 logic elements and 208 pins; for drop-in upgrade, verify timing closure against the -4 grade datasheet specifications.

What software is required to program the EPF8820ARI208-3?

The EPF8820ARI208-3 is programmed using Altera MAX+PLUS II (legacy, Windows) or Quartus Prime in legacy FLEX 8000 support mode. A configuration device such as EPC1, EPC2, or EPC16 is required for stand-alone SRAM configuration on power-up. Bitstream generation follows the standard Altera Programmer Object File (.pof) or SRAM Object File (.sof) flow.

Руководство по выбору

Choose the EPF8820ARI208-3 when you need an industrial-temperature (-40C to +85C) FLEX 8000 FPGA in a 208-pin PQFP package for sustaining an existing legacy design, particularly in factory automation, telecom, medical, or defense applications where re-spinning the FPGA would require expensive re-qualification. Choose EPF8820ARC208-3 instead if your design operates only in commercial 0C-70C environments - it is fully pin-compatible and uses the same silicon. For new designs, do NOT start with FLEX 8000 - target Cyclone II/III/V or MAX II/V CPLDs to avoid NRND supply constraints. All EPF8820 208-pin PQFP variants share the same bitstream, so a single firmware image works across the family.

Заметки по проектированию

The EPF8820ARI208-3 requires two separate power rails: VCCINT (5 V core supply, typically 250 mA quiescent) and VCCIO (3.3 V or 5 V I/O supply, bank-dependent current). Decoupling requires at least 4 x 0.1 uF ceramic + 1 x 10 uF tantalum per VCCINT pin group, plus 1 x 0.1 uF + 1 x 4.7 uF per VCCIO bank. Power-on sequencing is not strict - both rails may rise simultaneously per the FLEX 8000 datasheet. For new designs, consider migrating to a Cyclone II/III/V equivalent with single 1.2 V core supply for substantial power savings (typically >70%).

The 208-pin PQFP package has 0.5 mm lead pitch and requires careful PCB layout: 0.2 mm solder mask dam between pads, 0.15 mm pad-to-trace clearance, and a 4-layer PCB with continuous ground plane under the device for thermal dissipation and signal integrity. All VCCINT and VCCIO pins must be connected with wide (>=0.5 mm) traces or power planes. Keep configuration clock (DCLK) trace short and away from switching I/O to avoid configuration errors during power-up.

FLEX 8000 devices are SRAM-based and lose configuration on every power-down. A configuration EPROM (EPC1, EPC2, or EPC16 depending on bitstream size) is mandatory for stand-alone operation - designs that omit it will fail to initialize. Additionally, the -3 speed grade has tighter timing margin than -4; review your static timing analysis with the -3 grade delays before committing. Finally, the FLEX 8000 family is NRND - if you are starting a new design, target Cyclone II/III/V to avoid near-term obsolescence.
