EPF8820ARI208-2N Обзор

The Altera EPF8820ARI208-2N is a member of the FLEX 8000 family of SRAM-based programmable logic devices, delivering approximately 8,820 usable gates with 504 logic elements and a maximum of 78 user I/O pins in a 208-pin RQFP (Plastic Quad Flat Pack) surface-mount package. The "-2N" speed grade designation places it in Altera's mid-tier performance bin, while the trailing "N" indicates lead-free / lead-bearing compliant assembly per Altera's packaging nomenclature from the mid-1990s. The FLEX 8000 series was Altera's first architecture to combine FastTrack Interconnect with embedded logic array blocks (LABs), and this variant was widely adopted in telecommunications, industrial control, and glue-logic designs of the late 1990s and early 2000s.

A Field-Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer after manufacturing to implement arbitrary digital logic. FPGAs sit in the programmable logic hierarchy beneath ASICs (Application-Specific Integrated Circuits) but above simple PLDs (Programmable Logic Devices), offering a balance of density, performance, and time-to-market flexibility. The FLEX 8000 family specifically targets glue-logic, bus interfacing, and state-machine applications where discrete TTL or CPLD integration would be too large or too slow. EPF8820ARI208-2N operates on 5.0 V core supply and is supported by the MAX+PLUS II and Quartus design toolchains.

Key features of this device include FastTrack continuous routing architecture, four dedicated input pins, a global Clear signal, programmable output slew-rate control, and JTAG-compliant boundary-scan support per IEEE Std 1149.1. Each LAB contains eight logic elements (LEs), each LE consisting of a 4-input LUT, a programmable register, and carry/chain logic for arithmetic operations. The 208-pin RQFP package provides ample signal margin for legacy bus architectures including PCI, ISA, and VME.

Typical applications include telecommunications backplane glue logic, industrial motor-control state machines, legacy PCI interface bridges, and military/aerospace digital subsystems. The -2 speed grade is the most commonly specified FLEX 8000 variant, offering a balance of timing margin and cost for non-critical-path designs.

When designing with this device, engineers should note that the FLEX 8000 family is NRND (Not Recommended for New Designs) - modern Cyclone or MAX series devices are recommended for new projects. Existing designs should verify pinout compatibility before migration and consult Altera's migration guides for footprint and timing deltas. Designers should also provision 5.0 V tolerance on I/O banks interfacing with legacy 5 V logic families.

What is the difference between EPF8820ARI208-2N and EPF8820ARI208-2?

The EPF8820ARI208-2N includes a trailing 'N' suffix that designates lead-free / Pb-free assembly per Altera's packaging nomenclature. According to the FLEX 8000 datasheet family, both parts share identical die, pinout, and electrical specifications; the difference is purely in the lead-finish of the RQFP-208 package. Engineers migrating between the two must verify that downstream soldering processes accommodate the lead-free finish.

What family does EPF8820ARI208-2N belong to?

The EPF8820ARI208-2N belongs to the Altera FLEX 8000 programmable logic family, Altera's first architecture to combine FastTrack continuous interconnect with embedded Logic Array Blocks (LABs). The FLEX 8000 family was introduced in the mid-1990s and includes density members ranging from the EPF8282 (2,500 gates) up to the EPF81500 (16,000 gates), with the EPF8820 sitting in the mid-range at 8,820 usable gates.

How many logic elements does EPF8820ARI208-2N have?

The EPF8820ARI208-2N contains 504 logic elements (LEs) organized into 63 Logic Array Blocks (LABs) of 8 LEs each. According to the FLEX 8000 datasheet, each LE consists of a 4-input look-up table (LUT), a programmable register with carry and chain logic, and dedicated fast-input paths. This density supports mid-complexity glue-logic designs with up to approximately 8,820 usable gates.

Is EPF8820ARI208-2N still in production or obsolete?

What is the lead time for EPF8820ARI208-2N?

Lead time for the EPF8820ARI208-2N depends on source: authorized distributor stock typically ships in 1-2 weeks, broker/aftermarket inventory ships same-day to 1 week, and factory orders (where still accepted) typically require 12-16 weeks due to FLEX 8000 family NRND status. As of 2026-09-12, engineering samples from Intel FPGA's NRND program may be available on request, subject to MOQ requirements.

What is the best drop-in replacement for EPF8820ARI208-2N?

The best drop-in replacement for the EPF8820ARI208-2N (RQFP-208, FLEX 8000 family) within the same Altera ecosystem is the EPF8820ARI208-3N, which shares the identical pinout and die but offers a faster -3 speed grade. For pin-compatible migration to a different package, the EPF8820ARC208-2N (same RQFP-208 pinout, different lead-finish code) is also a true drop-in. Cross-brand drop-in replacements are not available - FLEX 8000 is an Altera-proprietary architecture.

What is the difference between FLEX 8000 speed grades -2 and -3?

The -2 and -3 speed grades in the FLEX 8000 family differ in internal timing margins: the -3 grade is faster (lower propagation delay through LUTs and interconnect), while the -2 is the standard mid-tier offering. According to Altera datasheet timing specifications, the -3 grade typically offers 15-25% better timing margin on critical paths. Both grades share identical pinout and electrical specs, making them drop-in compatible.

Can EPF8820ARI208-2N be used for new designs in 2026?

No, the EPF8820ARI208-2N is not recommended for new designs in 2026 due to its NRND status. For new FPGA projects, Intel (formerly Altera) recommends Cyclone IV, Cyclone V, or MAX V series devices, which offer lower power consumption, higher logic density, modern toolchain support (Quartus Prime), and active long-term supply. The EPF8820ARI208-2N remains in use only for maintaining legacy designs.

Pin 1 is located at the top-left of the package with the dot marker, following standard RQFP convention.

What are the key specifications of EPF8820ARI208-2N that engineers should know?

The EPF8820ARI208-2N is a 5.0V FLEX 8000 family FPGA with 504 logic elements (63 LABs), 78 user I/O, 8,820 usable gates, and SRAM-based configuration requiring an external EPC configuration device. It supports JTAG boundary scan per IEEE 1149.1, programmable output slew rate, and is housed in a 208-pin RQFP package. As of 2026-09-12, it carries NRND status with primary use in legacy industrial, telecom, and military designs.

What configuration device does EPF8820ARI208-2N require?

The EPF8820ARI208-2N, being SRAM-based, requires an external Altera EPC-series configuration device to load its configuration bitstream at power-up. Common pairings include the EPC2 (for FLEX 8000 devices), EPC1, or EPC4. The configuration device interfaces to the FPGA through dedicated pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) and supports JTAG in-system programming via IEEE 1149.1 boundary scan.

Is EPF8820ARI208-2N the same as EPF8820ARI208-3N?

No, the EPF8820ARI208-2N and EPF8820ARI208-3N are NOT the same part - they differ in speed grade. The '-2N' designation indicates the standard mid-tier speed grade, while '-3N' indicates a faster performance bin with tighter timing margins. Both share identical pinout, package (RQFP-208), and die, making them pin-compatible drop-in alternatives with timing variations.

Руководство по выбору

Choose EPF8820ARI208-2N when you need a 5.0V FLEX 8000 family FPGA in a 208-pin RQFP package for industrial temperature (-40C to +85C) applications requiring RoHS-compliant lead-free assembly. For commercial temperature (0C to +70C) designs, select EPF8820ARC208-2N or EPF8820ARC208-2 to reduce cost. For designs with relaxed timing closure, the EPF8820ARI208-1 (-1 speed grade) offers cost savings with 15-25% slower timing margin. The EPF8820AQC208-2N is preferred when an explicit Q-grade industrial variant is required for procurement specifications. New designs in 2026 should not select any FLEX 8000 variant - use Cyclone IV or MAX V devices with active long-term supply and modern toolchain support (Quartus Prime).

Заметки по проектированию

The EPF8820ARI208-2N requires 5.0V VCCINT (core) and a separate VCCIO (3.3V or 5.0V depending on I/O bank) with a 100-200 mA typical supply current. Decoupling requires 0.1 uF ceramic capacitors at every VCCINT/VCCIO pin and a bulk 22-47 uF tantalum or polymer capacitor at the supply rail entry point. Inrush current during configuration can spike to 500 mA; provision the regulator with adequate headroom.

Place the EPC configuration device within 50 mm of the FPGA's configuration pins (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) to minimize signal integrity issues. Use 4-layer PCB with dedicated ground and power planes. Route high-speed clock signals (GCLK1-3) with controlled impedance and matched lengths to avoid skew. Add series damping resistors (33 ohm) on clock nets if ringing is observed.

Do not leave MSEL pins floating - strap them to VCCINT or GND via 10 kohm resistors to define the configuration mode (typically MSEL[1:0]=00 for EPC2 passive-serial mode). The DEV_CLRn and DEV_OE pins, if unused, should be tied high via 10 kohm pull-ups. Failing to configure pull-ups properly can cause unexpected device reset or tri-state on power-up, leading to bus contention on shared I/O lines.
