EPF8636ALC84-4N

The EPF8636ALC84-4N is a FLEX 8000 family FPGA offering a register-rich, fine-grained programmable logic architecture in a surface-mount 84‑pin PLCC (J‑lead) package. It targets system-level functions such as bus interfaces, TTL integration, coprocessor tasks and high‑speed controllers where predictable interconnect and flexible logic are required.

Designed for commercial applications, this device combines configuration flexibility with on-board I/O and a 4.75 V to 5.25 V supply range, enabling integration into a wide range of 5 V digital systems while meeting RoHS environmental requirements.

Key Features

• Logic Resources — 504 logic elements provide compact LUT-based logic and registers for implementing combinational and sequential functions.
• Logic Array Blocks — 63 logic array blocks support structured placement of logic to aid predictable routing and performance.
• Gate Count — Specified with 6,000 gates for capacity planning in mid-density designs.
• I/O Capability — 68 user I/O pins enable multiple external interfaces and bus connections in a single device.
• Power and Voltage — Operates from 4.75 V to 5.25 V, matching standard 5 V system rails.
• Package and Mounting — 84‑pin PLCC (J‑Lead) package (29.31 × 29.31 mm) for surface-mount assembly in compact board layouts.
• Temperature and Grade — Commercial grade operation from 0 °C to 70 °C suitable for standard electronics applications.
• Memory — No embedded RAM (Total RAM bits: 0), allowing use as a pure logic fabric for control, glue logic, and bus functions.
• Family-level Architecture — FLEX 8000 family features such as FastTrack continuous routing, dedicated carry and cascade chains, and programmable output slew-rate control to manage switching noise and arithmetic performance.
• Environmental Compliance — RoHS compliant for lead-free manufacturing requirements.

Typical Applications

• Bus Interfaces: Implement multi‑bus glue logic and protocol translation where multiple 5 V buses must be consolidated or bridged.
• TTL Integration: Interface legacy TTL logic to modern systems using the device’s 68 I/O pins and 5 V supply compatibility.
• Coprocessor and Control Logic: Create custom coprocessor functions, custom instruction accelerators, or high‑speed control state machines using the register‑rich fabric.
• High-Speed Controllers: Design controllers for peripherals or subsystems that require predictable interconnect delays and dedicated arithmetic chains.
• DSP and Data Path Manipulation: Use the large register count and structured interconnect for wide-data-path operations and data transformation tasks.

Unique Advantages

• Register‑Rich Architecture: Family-level focus on high register count supports sequential logic and pipelining for data‑intensive designs.
• Predictable Interconnect: FastTrack continuous routing and dedicated chains reduce routing variability and simplify timing analysis.
• 5 V System Compatibility: 4.75 V–5.25 V supply rating and family MultiVolt I/O support enable straightforward integration into 5 V designs.
• Compact, Surface‑Mount Package: 84‑pin PLCC (J‑lead) offers a balance of I/O and board space efficiency for mid-density applications.
• Compliance and Assembly‑Ready: RoHS compliance and surface‑mount mounting type align with modern manufacturing processes.
• Design Tool Support (Family Feature): Family-level software support and automatic place‑and‑route are available through the documented MAX+PLUS II development environment for design productivity.
