EPF8636ALC84-3

The EPF8636ALC84-3 is a FLEX 8000 family programmable logic device offered in a 84-pin PLCC/J‑lead package. It delivers a register-rich FPGA architecture built from 504 logic elements across 63 logic array blocks, targeted for applications that require flexible glue logic, bus interfacing, and control functions.

Designed for 5.0 V systems (4.75 V to 5.25 V supply) and commercial temperature operation (0 °C to 70 °C), this device combines dense logic resources and system-level features that help streamline digital design integration on medium-density designs.

Key Features

• Core Logic: 504 logic elements organized in 63 logic array blocks, enabling compact implementation of combinational and sequential logic.
• Logic Capacity: Specified with 6,000 gates and a high register count consistent with FLEX 8000 family characteristics, suitable for medium-density programmable logic tasks.
• I/O Count & Levels: 68 available user I/O pins; device family supports mixed I/O signaling strategies for integration with 5.0 V and 3.3 V logic levels.
• Packaging & Mounting: Supplied in an 84‑lead LCC/PLCC (J‑Lead) package — supplier device package listed as 84‑PLCC with dimensions 29.31 × 29.31 mm — for surface-mount board assembly.
• Power & Temperature: Operates from 4.75 V to 5.25 V and rated for commercial temperature range of 0 °C to 70 °C.
• On‑chip Memory: No dedicated total RAM bits on-chip (0 bits), leveraging registers and logic for state and data storage.
• System Features (FLEX 8000 family): Family-level capabilities include in-circuit reconfigurability (ICR), programmable output slew-rate control, dedicated carry and cascade chains for arithmetic and high-fan-in logic, and low-power standby behavior.

Typical Applications

• Bus Interfaces: Implement multi-bus glue logic and protocol bridging where flexible pinouts and medium-density logic are required.
• TTL Integration: Integrate legacy TTL systems and translate between voltage domains using abundant I/O and family I/O signaling support.
• Coprocessor / Control Logic: Realize custom coprocessor functions, control-state machines, and peripheral registers that benefit from rich register resources.
• High‑Speed Controllers: Deploy as controllers for timing-critical subsystems where dedicated carry/cascade chains and predictable routing assist performance.

Unique Advantages

• Register‑Rich Architecture: High register count and 504 logic elements provide deterministic implementation of sequential logic and wide-data-path designs.
• In‑Circuit Reconfigurability: Supports ICR via external configuration devices or an intelligent controller, enabling field updates and flexible system provisioning.
• Dedicated Arithmetic Support: Built-in carry and cascade chains simplify implementation of adders, counters, and high-fan-in logic, reducing design complexity.
• Predictable Interconnect: Family routing structure is designed for fast, predictable interconnect delays to help meet timing targets.
• Commercial‑grade Reliability: Specified for commercial temperature operation (0 °C to 70 °C) and standard 5 V supply ranges, making it suitable for general-purpose embedded designs.
• Surface-Mount PLCC Package: 84‑lead J‑lead PLCC offers a compact board footprint and is compatible with common surface-mount assembly processes.
