EPF8636AQC208-4

The EPF8636AQC208-4 is an Intel FLEX 8000 family programmable logic device designed for register-rich, medium-density application designs. It implements a fine-grained logic architecture with 504 logic elements and a dense I/O complement, providing reconfigurable logic for bus interfaces, data transformation and control functions.

Targeted at commercial-grade embedded systems, the device offers 136 user I/O pins, a 4.75 V to 5.25 V supply range, and surface-mount 208-PQFP packaging, delivering integration and reconfigurability where predictable timing and high register counts are required.

Key Features

• Logic resources — 504 logic elements and 63 logic array blocks (LABs) to implement combinational and registered logic for control, glue logic, and moderate datapath functions.
• Gate equivalent — Specified as 6,000 gates, suitable for medium-density PLD uses where space and integration reduce BOM complexity.
• I/O and voltage — 136 user I/O pins and a recommended supply range of 4.75 V to 5.25 V for 5.0 V system integration.
• On-chip memory — Total on-chip RAM bits: 0 (no embedded RAM).
• Configuration and test — FLEX 8000 family supports in-circuit reconfigurability (ICR) via external configuration devices or an intelligent controller; family documentation also references JTAG boundary-scan (IEEE Std. 1149.1) support on selected devices.
• Interconnect and arithmetic support — Family-level features include FastTrack continuous routing and dedicated carry/cascade chains for implementing arithmetic and high-fan-in logic efficiently.
• Package and mounting — Surface-mount 208-BFQFP / 208-PQFP (28 × 28 mm) supplier device package for compact board-level integration.
• Operating conditions — Commercial grade with ambient operating range 0 °C to 70 °C.
• Environmental compliance — RoHS compliant.

Typical Applications

• Digital signal processing (DSP) — High register count and fine-grained logic resources make the device suitable for control and glue logic in DSP pipelines and data transformation tasks.
• Bus interfaces — 136 I/O pins and flexible I/O options support implementation of bus interface logic and multi-bus integration in embedded systems.
• TTL integration — Useful for TTL-level system integration and glue logic between legacy and modern subsystems in commercial electronics.
• Coprocessor and accelerator control — Implement control/status logic and custom peripheral interfaces that augment processor-based systems.
• High-speed controllers — Suitable for control and timing-critical logic in high-speed controller designs where predictable interconnect behavior is required.

Unique Advantages

• Register-rich architecture: 504 logic elements with substantial register resources enable efficient implementation of sequential logic and state machines.
• Predictable interconnect: Family-level FastTrack routing and dedicated carry/cascade chains simplify timing closure for arithmetic and wide fan-in logic.
• 5 V system compatibility: Device supply range (4.75 V–5.25 V) and family MultiVolt I/O concepts support integration into 5.0 V environments.
• Compact, surface-mount packaging: 208-PQFP (28 × 28 mm) package balances pin count and board density for commercial embedded assemblies.
• Reconfigurability and test support: In-circuit reconfigurability and family-level JTAG boundary-scan capabilities assist board-level testing and field updates.
• Regulatory readiness: RoHS compliance aligns the part with common environmental directives for commercial electronics.
