EPF8452AQC160-4 Ringkasan

The Altera (Intel) EPF8452AQC160-4 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs) with 4,000 usable gates, 336 logic cells, and 68 user I/Os, housed in a 160-pin BQFP/PQFP package. It operates from a 5 V supply at commercial temperature (0 C to 70 C) and supports in-circuit reconfigurability via industry-standard configuration EPROMs or Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441). The device is fabricated on a 0.42 um CMOS process and supports system clock frequencies up to 125 MHz.

A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that uses an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells to implement arbitrary digital logic. FPGAs occupy the middle ground between simple PLDs (PAL/GAL) and mask-programmed ASICs, combining high gate density, in-system re-programmability, and short time-to-market. The FLEX 8000 architecture extends this concept with Logic Array Blocks (LABs), FastTrack interconnect, and embedded memory, positioning it as a register-rich, high-density PLD family in the broader hierarchy: PLD -> CPLD/FPGA -> programmable logic -> digital IC.

Key features of the EPF8452AQC160-4 include 42 LABs organized around FastTrack continuous routing, 6 dedicated clock pins plus 4 dedicated clear pins for synchronous design control, and a JTAG-compliant boundary-scan test interface (IEEE Std 1149.1) for board-level test access. The 0.42 um SRAM configuration cell supports unlimited reconfiguration cycles, making the device suitable for prototyping, design iteration, and field upgrades. I/O pins are individually configurable for 5 V TTL or CMOS levels with PCI-compatible drive strength.

Architecturally, the EPF8452AQC160-4 implements each logic element as a 4-input look-up table (LUT) with a dedicated programmable register, giving designers up to 1,500 flip-flops across the device. Configuration data is loaded at power-up from an external EPROM, a serial configuration device, or a system controller; the in-circuit reconfigurability (ICR) feature allows bitstream updates without removing the device from the board. MultiVolt I/O compatibility supports mixed 3.3 V/5 V bus interfaces when used with external clamping.

Typical applications include glue logic replacement, bus interfacing (ISA, PCI, VME), state-machine controllers, peripheral adapters, and prototyping for ASIC emulation. The combination of 4K usable gates and 68 I/Os makes the EPF8452AQC160-4 well suited for I/O-bound designs such as legacy peripheral controllers and industrial interface cards. Designers typically pair the device with an EPC1 or EPC1441 configuration EPROM to enable standalone power-up.

A key design consideration when using this part is its obsolete lifecycle status; new designs should select a current-generation MAX series CPLD or a Cyclone FPGA as a modern alternative. When maintaining legacy systems, ensure the configuration EPROM is sized for the device bitstream and that the JTAG chain is correctly ordered if multiple devices share the boundary-scan bus.
