EPF81500ARC240-4 Tóm tắt

The Intel (formerly Altera) EPF81500ARC240-4 is a high-density member of the Flex 8000 family of CMOS programmable logic devices, delivering up to 16,000 usable gates and 1,500 registers in a 240-pin RQFP package. Built on a 0.42 µm CMOS process and operating from a 5 V supply, this -4 speed-grade device is rated for system-level frequencies up to 125 MHz, making it suitable for glue-logic, bus-interface, and high-volume control-plane designs.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose logic fabric, interconnect, and I/O blocks are configured after manufacturing by loading a user-defined bitstream. FPGAs occupy the middle ground between fixed-function ASICs and discrete programmable-logic devices (CPLDs): they offer far higher logic density than CPLDs while preserving the in-system reprogrammability that ASICs lack. Within the broader semiconductor taxonomy, an FPGA sits under Programmable Logic -> Programmable Devices -> Logic ICs -> Integrated Circuits.

Key features of the EPF81500ARC240-4 include 181 user I/O pins, 1,296 logic elements (cells), in-circuit reconfigurability (ICR) via external configuration devices, JTAG boundary-scan support (IEEE Std 1149.1), and dual-port SRAM-based configuration memory. The device also provides built-in PCI compliance, Multiply/Accumulate (MAC) blocks for DSP-like operations, and a fast track interconnect that shortens critical paths between logic-array blocks (LABs).

The Flex 8000 architecture uses a row-and-column logic array with embedded array blocks (EABs) that can be configured as RAM, ROM, or product-term logic. This hybrid approach lets designers implement wide datapath functions alongside random logic, which is uncommon in CPLDs of the same era. The -4 speed grade is the slowest of the Flex 8000 family, trading timing margin for cost and power reduction in non-timing-critical applications.

Typical applications include PCI bus bridges, peripheral controllers, telecommunications line cards, industrial automation controllers, and legacy ASIC replacement in long-lifecycle equipment where the design must remain in production for many years.

When designing with this part, note that the 5 V supply voltage is unusual in modern FPGA designs and must be paired with 5 V-tolerant peripherals. The RQFP-240 footprint is large by modern standards (32 mm × 32 mm body), and PCB layout must preserve the exposed thermal pad for heat spreading.
