EPF8452AQC160-3

The EPF8452AQC160-3 is a FLEX 8000 family programmable logic device from Intel, built as a CMOS FPGA architecture that combines compact look-up-table logic with programmable registers. It is targeted at embedded and system-level designs that require flexible, reconfigurable logic with substantial I/O capacity and deterministic routing for bus interfaces, control functions, and DSP-style datapaths.

Key architectural elements include 4-input LUT-based logic elements with dedicated arithmetic and cascade chains and support for in-circuit reconfigurability and JTAG boundary-scan test. The device is offered in a 160-pin surface-mount package and supports standard 5.0 V operation.

Key Features

• Logic Capacity — 336 logic elements organized to support a variety of combinational and registered functions, enabling mid-density programmable logic implementations.
• Logic Array Structure — Architecture includes dedicated carry and cascade chains for efficient arithmetic and wide fan-in functions, improving synthesis mapping for adders, counters, and comparators.
• I/O Density — Up to 120 user I/O pins, suitable for multi-bus integration and mixed-signal interface routing on a single device.
• Package and Mounting — 160-BQFP package case with surface-mount mounting; supplier device package listed as 160-PQFP (28×28), supporting compact board-level integration.
• Configuration and Test — In-circuit reconfigurability via external configuration devices or an intelligent controller and JTAG boundary-scan test circuitry for device-level testability (selected device support documented in family datasheet).
• I/O Flexibility — MultiVolt I/O interface capability described in the FLEX 8000 family, enabling device core operation at 5.0 V with I/O compatibility for 5.0-V and 3.3-V logic levels.
• Power and Operating Range — Specified supply voltage of 4.75 V to 5.25 V and commercial operating temperature range of 0 °C to 70 °C.
• Standards and Compliance — RoHS compliant and implemented in a CMOS process for low-power standby characteristics as described for the FLEX 8000 family.
• Design Tool Support — Family-level design support and automatic place-and-route provided by the MAX+PLUS II development system and common EDA interfaces referenced for FLEX 8000 devices in the datasheet.

Typical Applications

• Digital Signal Processing (DSP) — Provides a large register count and dedicated arithmetic chains for datapath manipulation, filtering, and transformation tasks.
• Bus Interfaces and Bridge Logic — High I/O count and predictable routing make the device suitable for implementing bus controllers and multi-bus integration on a single IC.
• High-Speed Control and Coprocessing — Dedicated carry/cascade resources and abundant registers support high-performance control logic and coprocessor functions.
• TTL Integration and Glue Logic — Flexible I/O and LUT-based logic elements enable seamless TTL-level interfacing and system glue functions.

Unique Advantages

• Balanced Mid-Density Logic: 336 logic elements provide a practical balance between gate count and design complexity for mid-range programmable designs.
• High I/O Count in a Compact Package: 120 user I/Os in a 160-pin surface-mount package reduce board-level routing complexity for multi-bus and multi-sensor systems.
• Deterministic Routing: Family routing architecture and dedicated chains deliver predictable timing for arithmetic and wide fan-in functions, simplifying timing closure.
• Reconfigurability and Testability: In-circuit reconfigurability and JTAG boundary-scan support streamline development, field updates, and manufacturing test flows.
• Straightforward Power Requirements: Operates from a standard 5.0 V supply (4.75 V–5.25 V), simplifying power distribution in legacy 5-V systems.
• Established Toolchain Support: Documented support for MAX+PLUS II and common EDA interfaces helps accelerate design entry, simulation, and place-and-route.
