EPF8820ARI208-2N Tóm tắt

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.
