EPF81188AQC240-2

The EPF81188AQC240-2 is a FLEX 8000 family programmable logic device from Intel. It combines a register‑rich, fine‑grained programmable-logic architecture with FastTrack continuous routing and dedicated arithmetic/cascade chains for predictable interconnect and high-speed logic functions.

Targeted at applications that require bus interfaces, wide-data-path manipulation, and control or coprocessor functions, the device offers 1,008 logic elements across 126 LABs, 184 user I/O pins, and support for in-circuit reconfigurability and MultiVolt I/O operation.

Key Features

• Core Logic — 1,008 logic elements organized into 126 logic array blocks (LABs), suitable for register‑rich designs and mid-density logic integration.
• Gate Equivalent — Approximately 12,000 usable gates to characterize device density for system planning.
• I/O Capacity — 184 user I/O pins to support multiple bus interfaces and external peripheral connections.
• Package & Mounting — 240‑pin BFQFP package (240‑PQFP, 32 × 32) with surface-mount mounting type for standard PCB assembly.
• Power and Voltage — Device supply 4.75 V to 5.25 V; MultiVolt I/O family support described in the FLEX 8000 documentation enables core operation at 5.0 V with I/O compatibility for 5.0‑V and 3.3‑V logic levels.
• Memory — No embedded RAM (Total RAM bits: 0); optimized for register-rich and logic-dominant implementations.
• Temperature Range — Commercial grade operation from 0 °C to 70 °C.
• Compliance — RoHS compliant.
• Family-Level System Features — FLEX 8000 family supports in-circuit reconfigurability via external configuration devices or intelligent controllers, and includes architectural features such as FastTrack Interconnect, dedicated carry and cascade chains, and programmable output slew-rate control.
• Design Ecosystem — Family documentation references supported design flows and software tool integration for automated place-and-route and common HDL/netlist formats.

Typical Applications

• Bus Interfaces — Integrate multiple 32‑bit buses or complex bus bridging functions using the device’s high pin count and logic resources.
• Digital Signal Processing (DSP) — Register-rich architecture supports wide-data-path manipulation and data transformation tasks in DSP pipelines.
• High-Speed Controllers — Implement control logic and timing-critical functions leveraging dedicated carry and cascade chains for arithmetic and high-fan-in operations.
• Coprocessor and Peripheral Integration — Offload specialized processing or glue logic between TTL-level peripherals and system buses.

Unique Advantages

• Register-Rich Architecture: 1,008 logic elements across 126 LABs provide a balance of logic density and plentiful registers for stateful designs.
• High I/O Count: 184 user I/O pins enable complex system interconnects and multiple bus instantiations without external IO expanders.
• Predictable Interconnect: FastTrack continuous routing and dedicated carry/cascade chains reduce routing unpredictability for timing-sensitive functions.
• MultiVolt I/O Support: Family-level MultiVolt I/O capability allows core and I/O level flexibility for mixed-voltage system integration.
• Standard Package & Assembly: 240‑pin BFQFP surface-mount package simplifies PCB layout and supports common assembly processes.
• Compliance & Supply Range: RoHS compliance and a defined 4.75 V–5.25 V supply window simplify regulatory and supply planning for commercial applications.
