EPF8636ALI84-4

The EPF8636ALI84-4 is an Intel FLEX 8000 family field‑programmable gate array supplied in an 84‑lead LCC (J‑lead) package. It provides a compact, register‑rich programmable logic resource with 504 logic elements and approximately 6,000 gates for mid‑density logic integration.

Designed for industrial environments, the device supports 68 user I/O pins, surface‑mount assembly, and a 4.75 V to 5.25 V supply range with an operating temperature span of −40 °C to 85 °C. It suits control, interface, and data‑path tasks where predictable routing and reconfigurability are required.

Key Features

• Core Architecture — 504 logic elements implemented across 63 logic array blocks (LABs) providing compact 4‑input LUTs and programmable registers for combinational and sequential logic.
• Logic Capacity — Approximately 6,000 gates of user logic to implement mid‑density designs including glue logic, state machines, and datapath functions.
• I/O — 68 user I/O pins in the 84‑lead LCC package, enabling multiple peripheral and bus interfaces in a compact footprint.
• No Embedded RAM — Total on‑chip RAM bits reported as 0; suitable for designs that rely on external memory or register‑based storage.
• Power and Supply — Operates from a 4.75 V to 5.25 V supply; FLEX 8000 family devices are described as having low standby current (typical 0.5 mA or less in standby mode) in family documentation.
• Package & Mounting — 84‑lead LCC (J‑lead) / 84‑PLCC supplier package (29.31 × 29.31 mm); surface‑mount mounting type for PCB assembly.
• Industrial Temperature Grade — Rated for −40 °C to 85 °C operation, suitable for industrial ambient conditions.
• Family‑Level System Features — FLEX 8000 family offers in‑circuit reconfigurability via external configuration devices or intelligent controllers, JTAG boundary‑scan test support on selected devices, programmable output slew‑rate control, and dedicated carry and cascade chains for arithmetic and high‑fan‑in logic (series features documented in the FLEX 8000 datasheet).

Typical Applications

• Bus Interfaces — Implement bus bridging and protocol adaptation where multiple TTL/logic buses must be consolidated or translated.
• High‑Speed Controllers — Control engines and finite state machines for industrial controllers, leveraging the register‑rich fabric and predictable routing.
• Coprocessor and Glue Logic — Offload custom acceleration or implement glue logic between processors, peripherals, and custom ASICs.
• Digital Signal Processing (DSP) Support — Use registers and logic elements for wide‑data‑path manipulation and fixed‑function data transforms within mid‑density constraints.

Unique Advantages

• Compact Mid‑Density Integration: 504 logic elements and about 6,000 gates provide a balance between capacity and board space for moderate complexity designs.
• Industrial Reliability: −40 °C to 85 °C rating and surface‑mount 84‑lead PLCC/LCC packaging support deployment in industrial environments.
• Predictable Routing and Arithmetic Support: FLEX 8000 family features dedicated carry and cascade chains and continuous routing to simplify implementation of adders, counters, and high‑fan‑in logic.
• Flexible I/O Compatibility: 68 user I/O pins in the PLCC package enable multiple peripheral connections and bus implementations in a small footprint.
• Reconfigurability and Testability: Family‑level support for in‑circuit reconfigurability and JTAG boundary‑scan (on selected devices) simplifies development, updates, and board‑level test.
• Low Standby Power (Family‑Level): FLEX 8000 documentation reports low standby current (typical 0.5 mA or less), useful for systems with idle periods.

Why Choose EPF8636ALI84-4?

The EPF8636ALI84-4 delivers mid‑density programmable logic in an industrial‑rated PLCC/LCC package, combining 504 logic elements, 68 I/O, and surface‑mount packaging for compact, reliable designs. It is appropriate for engineers who need a reprogrammable device for control logic, bus interfaces, DSP support, or coprocessor functions while maintaining tight board area and power constraints.

Backed by the FLEX 8000 family architecture and its documented features—such as dedicated arithmetic chains, in‑circuit reconfigurability options, and family‑level low standby current—this device provides a pragmatic option for long‑running products that require field updateability and predictable routing characteristics.
