EPF81500ARI240-3 Tóm tắt

The Intel (formerly Altera) EPF81500ARI240-3 is a member of the FLEX 8000 programmable logic family, delivering up to 16,000 usable gates, 1,296 logic cells (registers), and 181 user I/O pins in a 240-pin RQFP (Power Quad Flat Pack) package with exposed pad. Built on a 0.42 µm CMOS SRAM process, it operates from a 5 V supply and is rated for a maximum internal clock frequency of 125 MHz.

A Field-Programmable Gate Array (FPGA) is a reprogrammable semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and configurable I/O cells. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> programmable logic -> logic ICs -> integrated circuits, and are widely used to implement glue logic, custom state machines, bus bridges, and DSP datapaths without the cost and lead time of an ASIC. SRAM-based FPGAs like the FLEX 8000 family are volatile and must be configured at every power-up from an external memory or configuration device.

Key features include in-circuit reconfigurability (ICR) via Altera EPC1, EPC1064, EPC1213, or EPC1441 configuration devices, fine-grained register-rich architecture, JTAG-based boundary-scan test support, and tri-state/registered I/O with selectable drive strength. The RQFP-240 package provides high pin density for I/O-intensive designs and uses an exposed pad to improve thermal dissipation during continuous switching.

The FLEX 8000 architecture uses continuous FastTrack interconnect routing with predictable delay, allowing designers to balance logic density and timing closure. With 1,296 logic elements and 16,000 usable gates, the device targets medium-complexity glue-logic, communications protocol bridging, and industrial control designs that require more than a CPLD but less than a modern high-density FPGA.

Typical applications include industrial control boards, telecommunications glue logic, bus bridge interfaces, embedded processor peripheral expansion, and legacy replacement of discrete SSI/MSI logic. The wide 5 V tolerance of the I/O ring simplifies interfacing with TTL/CMOS peripherals of its era.

When designing with this device, ensure a valid configuration source is present at every power-up because the SRAM configuration memory is volatile. Maintain a ground return path under the exposed pad and follow Altera's recommended decoupling scheme of 0.1 µF + bulk capacitors placed adjacent to each power pin.
