EPF8820AQC160-2

The EPF8820AQC160-2 is a FLEX 8000 series programmable logic device that combines fine-grained logic elements with a fast, continuous routing fabric. Designed for applications requiring register-rich logic and predictable interconnect delays, this device targets bus interfaces, controller functions, and wide-data-path manipulation in commercial-temperature systems.

Built for in-circuit reconfiguration and flexible I/O usage, the device delivers a compact solution with 672 logic elements and 120 user I/O pins in a 160-pin PQFP package, operating from a 4.75 V to 5.25 V supply and rated for 0 °C to 70 °C.

Key Features

• Core logic capacity — 672 logic elements providing approximately 8,000 usable gates for moderate-density programmable logic implementations.
• Logic array blocks — 84 logic array blocks that organize the device fabric for predictable placement and routing.
• I/O and packaging — 120 user I/O pins in a 160-PQFP (28×28 mm) surface-mount package suitable for high-pin-count board designs.
• Power and temperature — 4.75 V to 5.25 V supply range and commercial operating grade, 0 °C to 70 °C.
• No embedded SRAM — Total on-chip RAM bits: 0; suitable for designs that use external memory or focus on logic and registers.
• In-system configurability — Supports in-circuit reconfigurability (ICR) via external configuration devices or an intelligent controller, enabling field updates.
• Flexible I/O options — FLEX 8000 family MultiVolt I/O architecture supports compatibility with 5.0 V and 3.3 V logic levels at the I/O pins while the device core operates at 5.0 V.
• Dedicated arithmetic support — Family-level dedicated carry and cascade chains accelerate adders, counters, comparators, and high-fan-in logic functions.
• Signal integrity controls — Programmable output slew-rate control to help reduce switching noise in mixed-signal and dense board layouts.
• Family-level design support — FLEX 8000 devices are supported by development tools and standard HDL/netlist flows for automated place-and-route and simulation.

Typical Applications

• Bus interfaces — Implement multi-bus bridging and protocol glue logic where predictable timing and moderate gate count are required.
• High-speed controllers — Use the device’s register-rich fabric and dedicated arithmetic chains for control logic in motor drives, peripheral controllers, and embedded controllers.
• TTL and legacy logic integration — 5.0 V I/O compatibility makes the device well suited for interfacing with TTL-based systems and legacy boards.
• Data transformation and DSP glue — Deploy for wide-data-path manipulation and data formatting in front-end processing or coprocessor-support roles.

Unique Advantages

• Balanced density and register count: 672 logic elements and abundant registers support state-heavy designs without excessive footprint.
• Predictable interconnect: The FLEX family’s continuous routing structure helps deliver consistent timing and simplifies timing closure for place-and-route flows.
• Field reconfigurability: In-circuit reconfiguration enables updates and design iterations without board changes, reducing lifecycle costs.
• Practical I/O flexibility: MultiVolt I/O compatibility eases integration into mixed-voltage systems and supports legacy logic levels.
• Dedicated arithmetic resources: Carry and cascade chains accelerate common arithmetic and high-fan-in logic, improving performance for counters and adders.
• Commercial-grade availability: Surface-mount 160-PQFP packaging and RoHS compliance suit mainstream production and environmental requirements.
