EPF8452AQC160-4N Tóm tắt

The Altera (now Intel) EPF8452AQC160-4N is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), providing 336 logic elements (LEs) and 120 user I/Os in a 160-pin Plastic Quad Flat Pack (PQFP / QFP) package. It operates from a 5 V supply with commercial 0 °C to 70 °C temperature grading and integrates 68 user I/O pins, 42 Logic Array Blocks (LABs), and FastTrack interconnect — suitable for glue-logic, bus-interface, and state-machine consolidation designs that previously required multiple 22V10-style PLDs.

What is an FPGA? An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) category that sits above simple PLDs and CPLDs in the semiconductor hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The FLEX 8000 family was Altera's first high-density FPGA architecture, using SRAM configuration cells that allowed in-circuit reconfigurability (ICR) via industry-standard EPROM, Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441), or a system controller. Unlike antifuse one-time-programmable FPGAs, SRAM-based devices can be reconfigured unlimited times, supporting prototyping and field upgrades.

Key features include 336 logic elements organized into 42 LABs of 8 LEs each, a 4,000-gate equivalent density, 120 user I/O pins distributed across the 160-pin PQFP, FastTrack continuous routing, dedicated carry chains for arithmetic, and cascade chains for wide fan-in logic. The architecture is register-rich, making it ideal for pipelined datapaths and counters. The device supports both 5.0 V and 3.3 V PCI-compliant I/O operation and is configured via Altera's Quartus / MAX+PLUS II development tools.

Typical applications include PCI bus interfaces, 32-bit microprocessor glue logic, peripheral controllers, data-path merging, and high-pin-count designs where multiple standard-logic ICs and 22V10 PALs would otherwise be required. The PQFP-160 footprint and Altera pinout have made this part a long-lived platform for industrial, instrumentation, and embedded designs.

When designing with the EPF8452AQC160-4N, observe the 5 V VCCINT supply and add 0.1 µF / 10 µF decoupling close to each VCC/GND pair. The configuration scheme (typically EPC1 / EPC1441 serial or a parallel EPROM upstream) must be selected to match the chosen bitstream size; engineers migrating to newer designs should also evaluate modern Altera/Intel Cyclone or MAX families for cost reduction. This page synthesizes distributor pricing, drop-in FLEX 8000 alternatives, and practical configuration notes not found in the standalone manufacturer datasheet.
