EPF8636ALC84-4

The EPF8636ALC84-4 is a member of the FLEX 8000 programmable logic device family optimized for moderate-density, register-rich logic implementations. It provides a compact FPGA fabric with 504 logic elements and support for 68 user I/O pins, packaged in an 84-pin LCC (J-lead) surface-mount package for space-constrained commercial designs.

Designed for 5.0 V system environments, this commercial-grade device targets applications such as bus interfaces, high-speed controllers, TTL integration and digital signal/data manipulation where predictable logic routing and reconfigurability are important.

Key Features

• Logic Capacity — 504 logic elements provide the core programmable resources for combinational and registered logic implementations.
• Logic Array Blocks (LABs) — 63 LABs to organize logic resources for predictable routing and partitioning.
• Gate Equivalent — Approximately 6,000 gates for estimating system-level logic requirements.
• I/O — 68 user I/O pins suitable for bus interfaces, peripheral connections and TTL-level integration.
• Supply Voltage — Operates from 4.75 V to 5.25 V, matching standard 5.0 V system rails.
• Package & Mounting — 84-LCC (J-Lead) surface-mount package (supplier device package: 84-PLCC, 29.31 × 29.31 mm footprint) for board-level integration.
• Operating Temperature — Commercial temperature range of 0 °C to 70 °C for typical commercial applications.
• Embedded Memory — Total on-chip RAM bits: 0 (logic-focused fabric without embedded RAM blocks).
• Compliance — RoHS compliant, enabling use in environments requiring lead-free components.
• Family-Level Architecture — As part of the FLEX 8000 family, benefits include features such as in-circuit reconfigurability, dedicated carry and cascade chains, FastTrack interconnect for predictable routing delays, and programmable output slew-rate control.

Typical Applications

• Bus Interfaces & Bridge Logic — Integrate multiple bus segments, implement address decoding or glue logic between TTL/legacy interfaces and system peripherals using the device’s 68 I/O pins.
• High-Speed Controllers — Implement control engines and timing-critical state machines leveraging the register-rich logic fabric and dedicated arithmetic/cascade chains.
• TTL Integration & System Glue — Replace discrete glue logic in 5 V systems with a single, reconfigurable PLD to reduce board complexity and BOM count.
• Data Transformation & DSP Building Blocks — Use the abundant registers and logic elements for data path manipulation, wide-data multiplexing, and mid-range DSP functions.

Unique Advantages

• Balanced Logic Density: 504 logic elements deliver a mid-range capacity that simplifies migration from discrete logic while keeping board area and cost in check.
• 5 V System Compatibility: Direct support for 4.75 V to 5.25 V supplies aligns the device with legacy and industry-standard 5 V designs.
• Surface-Mount PLCC Packaging: The 84-LCC (J-lead) package provides a compact, serviceable form factor for through-board mounting or rework-friendly assembly practices.
• Family-Level Architectural Features: FLEX 8000 family attributes such as FastTrack interconnect and dedicated carry/cascade chains provide predictable timing and efficient arithmetic implementation.
• Commercial Grade & RoHS Compliant: Suited for mainstream commercial applications with environmental compliance for lead-free manufacturing.
• Reconfigurability: Support for in-circuit reconfigurability at the family level enables board-level flexibility and field updates when used with appropriate external configuration devices or controllers.
