EPF8452ALI84-4

The EPF8452ALI84-4 is an industrial-grade FLEX 8000 family field programmable gate array (FPGA) in an 84-lead PLCC (J‑lead) surface-mount package. It provides moderate logic density and I/O capability for mid-range embedded applications that require in-field configurability and reliable operation across industrial temperature ranges.

Designed for system-level integration, this device targets applications such as digital signal processing, bus interfaces and high-speed controllers where a 5.0 V supply domain and robust I/O count are required.

Key Features

• Logic Capacity — 336 logic elements and approximately 4,000 gates to implement moderate-complexity logic and control functions.
• I/O and Packaging — 68 user I/O pins in an 84‑PLCC (29.31 × 29.31 mm) J‑lead package; surface-mount mounting for compact board integration.
• Power Supply — Operates from a 4.75 V to 5.25 V supply, compatible with 5.0 V system domains.
• Temperature and Grade — Industrial-grade device with an operating temperature range of −40 °C to 85 °C for deployment in demanding environments.
• Memory — No embedded on-chip RAM (Total RAM Bits: 0); logic and registers are provided by the FLEX architecture.
• Family-Level Architecture — Built on the FLEX 8000 programmable-logic family; family features include in-circuit reconfigurability, dedicated carry and cascade chains, and flexible interconnects for predictable routing (family-level feature set).
• Standards & Compliance — RoHS compliant.

Typical Applications

• Digital Signal Processing (DSP) — Provides a high register count and flexible logic resources suitable for DSP building blocks and data-path manipulation.
• Bus Interfaces and TTL Integration — 68 I/O pins and 5.0 V supply compatibility make this device suitable for bus bridging and TTL-level system interfaces.
• Coprocessor and Control Functions — Useful for offloading control logic or implementing specialized coprocessor tasks in embedded systems.
• High-Speed Controllers — FLEX 8000 family routing and dedicated arithmetic chains support deterministic timing for controller designs.

Unique Advantages

• Mid-range logic density: 336 logic elements and ~4,000 gates strike a balance between capability and cost for many embedded designs.
• Robust industrial operation: Industrial temperature rating (−40 °C to 85 °C) and surface-mount PLCC packaging enable deployment in industrial equipment.
• 5 V system compatibility: 4.75 V to 5.25 V supply range avoids extra level-shifting for 5.0 V domains.
• Flexible I/O count: 68 user I/O pins support multiple bus connections and peripheral interfaces on a single device.
• Family-level design ecosystem: Part of the FLEX 8000 family, which is supported by established place-and-route and design-entry tools (family-level support).
• Regulatory readiness: RoHS compliance supports modern manufacturing and environmental requirements.
