EPF8820ATC144-2N

The EPF8820ATC144-2N is a FLEX 8000 family field-programmable logic device offering a register-rich CMOS architecture targeted at moderate-density programmable logic applications. The device implements logic in compact logic elements (LEs) and delivers predictable interconnect behavior suitable for bus interfaces, TTL integration, coprocessor functions and high-speed control tasks.

With 672 logic elements, 84 logic array blocks, and 112 user I/O pins in a 144-LQFP package, this commercial-grade, surface-mount FPGA supports 5.0 V supply operation and is RoHS compliant.

Key Features

• Core Architecture Register-rich FLEX 8000 architecture using compact 4-input look-up tables and programmable registers for implementing combinational and sequential logic.
• Logic Capacity 672 logic elements distributed across 84 logic array blocks, representing approximately 8,000 usable gates for moderate-density applications.
• I/O and Voltage 112 user I/O pins; MultiVolt™ I/O support enables the device core to run at 5.0 V while I/O pins are compatible with 5.0 V and 3.3 V logic levels. Recommended supply range: 4.75 V to 5.25 V.
• Interconnect and Arithmetic Support FastTrack® continuous routing for predictable interconnect delays, plus dedicated carry and cascade chains to implement fast adders, counters and high-fan-in logic.
• Configuration and Test In-circuit reconfigurability (ICR) via external configuration devices or an intelligent controller; family includes devices with built-in JTAG boundary-scan test (BST) circuitry.
• Signal Integrity Controls Programmable output slew-rate control to reduce switching noise and peripheral register options to optimize setup and clock-to-output timing.
• Memory and Registers Register-rich device optimized for flip-flop and register-heavy implementations; Total RAM bits reported as 0.
• Package and Grade Commercial grade, surface-mount package case 144-LQFP (supplier package 144-TQFP, 20 × 20 mm) for medium-pin-count board designs.
• Environmental Compliance RoHS compliant.
• Operating Conditions Specified operating temperature range: 0 °C to 70 °C.

Typical Applications

• Bus Interfaces Integrate multiple buses or implement custom bus adapters using the device’s high I/O count and predictable interconnect.
• TTL Integration Bridge legacy TTL logic to modern systems with the device’s MultiVolt I/O compatibility and abundant register resources.
• Coprocessor and Control Logic Implement custom coprocessor functions and high-speed controllers leveraging dedicated carry/cascade chains and peripheral register options for timing control.
• DSP and Data-Path Manipulation Suitable for wide-data-path manipulation and data transformation tasks that benefit from a register-rich fabric and deterministic routing.

Unique Advantages

• Register-Rich Architecture: Compact 4-input LUTs with plentiful registers make the device well-suited to sequential logic and pipelined designs.
• Predictable Routing: FastTrack® interconnect provides continuous routing for consistent timing behavior across designs.
• Built-in Arithmetic Support: Dedicated carry and cascade chains simplify implementation of adders, counters and high-fan-in logic without custom routing.
• Flexible I/O Voltage Handling: MultiVolt™ I/O enables mixed-voltage system integration while keeping the core at 5.0 V.
• Compact Medium-Pin Package: 144-LQFP (20 × 20 mm) delivers 112 user I/Os and 672 LEs in a surface-mount footprint suited to space-conscious PCBs.
• Industry Tool Support: Family-level documentation indicates support for standard development toolflows and in-circuit configuration methods to streamline implementation.
