EPF8820ABC225-4

The EPF8820ABC225-4 is a FLEX 8000 family programmable logic device designed for register-rich, high-density logic implementations. With 672 logic elements and support for approximately 8,000 usable gates, this device targets applications that require medium-density FPGA functionality in a compact 225‑BGA package.

Built for system-level flexibility, the device supports in-circuit reconfigurability and a FastTrack® continuous routing structure for predictable interconnect delays. It is well suited for bus interfaces, data-path processing, and general-purpose controller functions where a combination of logic density, I/O count, and reconfigurability are important.

Key Features

• Logic Density — 672 logic elements and a device-class capacity of approximately 8,000 usable gates, organized across 84 logic array blocks (LABs) for compact combinational and registered logic.
• Registers / Flip‑Flops — High register count appropriate for synchronous designs (device family documentation lists flip‑flop resources associated with this class of device).
• I/O and Voltage — 152 user I/O pins with MultiVolt I/O capability described for the FLEX 8000 family; device voltage supply specified at 4.75 V to 5.25 V to support 5.0 V operation.
• Interconnect & Arithmetic — FastTrack® continuous routing and dedicated carry/cascade chains (family features) provide predictable routing delays and support for fast adders, counters, and comparators.
• Configuration & System Features — In‑circuit reconfigurability (ICR) via external configuration devices or controllers and family-level support for PCI Local Bus Specification Revision 2.2 at 5.0 V operation.
• Package & Mounting — Surface-mount 225‑BGA (19 × 19) package, suitable for high‑pin‑count board integration while minimizing board footprint.
• Commercial Temperature Grade — Operating temperature range specified 0 °C to 70 °C for commercial applications.
• Embedded Memory — No on-chip RAM bits documented for this device class in the available data.
• Standby Power — Family documentation lists low standby current characteristics (typical family guidance).

Typical Applications

• Data-path and DSP functions — Medium-density logic and plentiful registers make the device suitable for wide-data-path manipulation and DSP front-end tasks.
• Bus Interfaces and Glue Logic — High I/O count and 5.0 V-compatible operation enable integration with TTL buses and board-level interface logic.
• Coprocessor and Acceleration Blocks — Dedicated carry and cascade chains accelerate arithmetic and high‑fan‑in logic commonly used in coprocessor or accelerator designs.
• High‑Speed Controllers — Continuous routing and predictable interconnect delays support controller implementations requiring deterministic timing.

Unique Advantages

• Balanced Logic and Register Resources: 672 logic elements combined with a high register count provide a compact, register-rich fabric for synchronous designs.
• Predictable Interconnect: FastTrack® continuous routing reduces variability in routing delays, simplifying timing closure for mid-density applications.
• Flexible System Integration: 152 user I/Os in a 225‑BGA footprint enable multiple bus interfaces and board-level consolidation while minimizing PCB area.
• In-Circuit Reconfigurability: Support for ICR via external configuration devices allows field updates and iterative development without board-level changes.
• 5.0 V Operation Compatibility: Device supply range (4.75 V to 5.25 V) and family-level PCI compatibility support legacy 5.0 V systems and interfaces.
