EPF8820ARC208-2

The EPF8820ARC208-2 is a member of the FLEX 8000 programmable logic device family, delivering medium-density, register-rich reconfigurable logic for commercial applications. It implements logic in compact logic elements and is suitable for bus interfaces, TTL integration, coprocessor functions and high-speed controller tasks where a 5.0 V supply environment and extensive I/O are required.

Designed with flexible routing and dedicated arithmetic resources, the device targets system-level integration and rapid design iteration while supporting standard FPGA development flows and toolchains.

Key Features

• Core Capacity — 672 logic elements arranged across 84 logic array blocks, providing approximately 8,000 usable gates and a rich register count for sequential logic.
• I/O and Voltage — 152 user I/O pins with MultiVolt I/O capability in the FLEX 8000 family; device supply range specified at 4.75 V to 5.25 V to match 5.0 V system environments.
• Dedicated Arithmetic and Logic Chains — Family-level architecture includes dedicated carry and cascade chains for fast adders, counters, and high‑fan‑in logic functions to simplify arithmetic implementation.
• Flexible Routing — FastTrack continuous routing structure (family feature) for consistent, predictable interconnect delays across the array.
• In-Circuit Reconfigurability — Supports in-circuit reconfigurability via external configuration devices or an intelligent controller (family capability).
• Package and Mounting — 208-BFQFP with exposed pad; supplier package referenced as 208-RQFP (28×28). Surface-mount device suitable for standard PCB assembly.
• Operating Range and Compliance — Commercial grade with operating temperature 0 °C to 70 °C and RoHS compliance for regulatory alignment.
• Design Tool Support — FLEX 8000 family provides software design support and automatic place-and-route through the MAX+PLUS II development system and supports standard HDL and netlist flows for simulation and synthesis (family-level information).

Typical Applications

• Bus Interface and Bridge Logic — Use the device to implement custom bus-handling logic, protocol bridging, and glue logic for 5.0 V systems where extensive I/O is required.
• High-Speed Controllers — Implement control state machines and timing-critical interfaces that benefit from the device’s dedicated carry/cascade chains and predictable routing.
• TTL Integration and System Glue — Ideal for integrating TTL-level peripherals and consolidating multiple discrete logic functions into a single programmable device.
• Coprocessor and Accelerator Functions — Offload specialized arithmetic or control functions into the FPGA fabric using the available logic elements and register resources.

Unique Advantages

• Well-balanced Density: 672 logic elements and approximately 8,000 gates provide medium-density capability for consolidating multiple logic functions without excessive BOM growth.
• Extensive I/O Count: 152 user I/O pins support high pin-count designs and multiple bus connections in a single device footprint.
• 5 V System Compatibility: Supply range of 4.75 V to 5.25 V enables straightforward integration into 5.0 V environments common in legacy and mixed-voltage systems.
• Deterministic Routing: Family-level FastTrack interconnect and dedicated chains help maintain predictable timing for arithmetic and control paths.
• Assembly-Friendly Package: 208-pin BFQFP with exposed pad and surface-mount mounting supports standard PCB assembly processes.
• Design Ecosystem: Family support for MAX+PLUS II and common HDL/netlist flows eases integration into existing FPGA development toolchains.
