EPF81500ARC240-2A Ringkasan

The Intel (Altera) EPF81500ARC240-2A is a member of the FLEX 8000 family of register-rich, high-density CMOS programmable logic devices (PLDs), delivering up to 16,000 usable gates and 1,500 logic registers in a 240-pin RQFP (BFQFP with exposed pad) package. Built on a 0.42 umm CMOS SRAM process, it provides in-circuit reconfigurability (ICR) through external configuration devices or an intelligent host controller, allowing designers to update logic in-system without removing the device.

A Field Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing to implement custom digital logic. FPGAs sit within the broader semiconductor hierarchy as reconfigurable logic -> programmable logic device (PLD) -> logic IC -> integrated circuit. The FLEX 8000 family was designed to integrate multiple 32-bit buses into a single device, making it suitable for glue-logic, bus-bridging, and high-density state-machine implementations in telecom, industrial, and computing systems.

Key features of the EPF81500ARC240-2A include 1,296 logic elements (LEs), 181 user I/O pins, and system-level support for in-circuit reconfigurability through industry-standard parallel EPROM or Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441). Operating from a 5V supply, the device achieves a typical internal performance of approximately 125 MHz. The 240-pin BFQFP package with exposed pad provides a robust thermal path for high-density designs.

The architecture combines a fine-grained logic element array with continuous FastTrack interconnect routing, enabling predictable timing and high logic utilization. Multiple Logic Array Blocks (LABs) are interconnected via row and column channels, and each LE contains a 4-input look-up table (LUT), a programmable register, and dedicated carry and cascade chains for arithmetic and wide functions.

Typical applications include telecommunications bridging, industrial control glue logic, high-density state machines, and legacy system upgrades where multiple TTL/CMOS devices can be consolidated into a single FLEX 8000 FPGA. The high pin count and exposed pad also suit high-pin-count applications such as multi-bus integration.

When designing with this device, ensure correct configuration mode (serial vs parallel) and proper power-up sequencing of VCCINT and VCCIO rails. The exposed pad of the 240-RQFP must be soldered to a sufficiently large copper pour for thermal dissipation, especially when many I/O are switching simultaneously.

Per the verified distributor data, Heisener quotes an estimated delivery window of Aug 1 to Aug 6 (or Nov 26 to Dec 1 on a later listing) when expedited shipping is selected. Because the part is obsolete, lead times may extend if inventory must be located outside the primary distributor warehouse. Always request a current quote.
Is EPF81500ARC240-2A in stock anywhere?
Per distributor listings as of 2026-09-12, the EPF81500ARC240-2A is in limited stock at Heisener (2,736 and 3,360 piece listings reported). Stock varies by distributor and time of query, and because the part is obsolete, quantities are finite. Independent distributors may also hold unreleased inventory; we recommend requesting a quote for the most current stock status.
What is the difference between EPF81500ARC240-2 and EPF81500ARC240-2A?
The 'A' suffix on the EPF81500ARC240-2A denotes a specific variant of the EPF81500ARC240-2 base part, typically indicating a minor revision, temperature grade, or factory option within the FLEX 8000 family. Both parts share the same 240-RQFP package, 16K-gate density, and 1,296 logic elements. Always verify pinout and electrical compatibility against the FLEX 8000 family datasheet before substituting.
What is the best drop-in replacement for EPF81500ARC240-2A?
The closest drop-in alternative within the same FLEX 8000 family and 240-RQFP package is the EPF81500ARC240-2 (without the 'A' suffix), which shares identical die and footprint. For higher pin-count FLEX 8000 designs, the EPF81500AQC240-2/3/4 family variants offer the same 240-RQFP footprint. Cross-brand drop-in replacements from other vendors are not available due to the proprietary Altera configuration scheme.
EPF81500ARC240-2A vs EPF81500AQC240-2 - which is better for a 5V industrial design?
Both the EPF81500ARC240-2A and EPF81500AQC240-2 share the same FLEX 8000 family core, 16K gates, 1,296 LEs, and 240-RQFP package, so they are electrically and pin-compatible. The 'ARC' and 'AQC' suffixes denote different speed grades and temperature ranges. For a 5V industrial design, choose based on the required operating temperature window and timing margin rather than functional differences - the silicon is functionally identical.
When should I choose EPF81500ARC240-2A over a modern Cyclone FPGA?
Choose the EPF81500ARC240-2A only when maintaining or replicating a legacy design where the existing PCB footprint, configuration scheme, and design files were built around the FLEX 8000 family. For new designs, modern Intel (Altera) Cyclone or MAX families provide higher logic density, lower power, modern I/O standards (LVDS, DDR), and active support. The FLEX 8000 device is obsolete and not recommended for new production.

What is the pinout of EPF81500ARC240-2A?
The EPF81500ARC240-2A pinout is defined in the FLEX 8000 Device Family datasheet. The 240-RQFP package dedicates 181 pins to user I/O, with the remainder used for VCCINT, VCCIO, GND, JTAG (TMS, TCK, TDI, TDO), configuration (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0), and dedicated inputs (DEV_CLRn, DEV_OE, MSEL pins for selecting configuration mode). Refer to the family datasheet for the exact pin assignment table.
What are the key specifications of EPF81500ARC240-2A that engineers should know?

Panduan Pemilihan

Choose the EPF81500ARC240-2A when you must maintain a legacy design originally built around the FLEX 8000 family on a 240-RQFP PCB, especially when the design was compiled with the MAX+PLUS II toolchain and the existing configuration device (EPC1, EPC1064, EPC1213, or EPC1441) must be reused without redesign. Prefer the -2 speed grade for timing-critical paths operating near 125 MHz. For modern new designs, migrate to Intel Cyclone IV or Cyclone 10 LP families instead, which provide active support, modern I/O standards (LVDS, DDR memory interfaces), and lower core voltages. If the original EPF81500ARC240-2A is unavailable, the EPF81500AQC240-2 (same speed grade, same die, same 240-RQFP package) is the closest drop-in substitute; the -3 and -4 speed grades offer slower timing bins that may close timing but consume less power.

Catatan Desain

The EPF81500ARC240-2A requires both VCCINT (5V core) and VCCIO (I/O bank voltage) supplies. According to the FLEX 8000 family datasheet, VCCINT and VCCIO must be sequenced correctly during power-up to avoid latch-up or spurious configuration. Place decoupling capacitors (0.1 uF ceramic plus 10-47 uF bulk) as close as possible to every VCCINT and VCCIO pin. Use independent supply rails if possible to control inrush current.

The 240-RQFP exposed pad MUST be soldered to a thermal copper pour on the PCB to dissipate heat from simultaneous I/O switching. Estimated: at 181 I/O switching at 5V with capacitive loads, the device can dissipate several watts. Provide at least 1 square inch of continuous copper connected to the exposed pad and use thermal vias to inner ground planes to keep junction temperature within the operating range.

Do not confuse MSEL pin configuration mode settings - selecting the wrong mode can prevent configuration from completing. Verify MSEL[2:0] against the FLEX 8000 datasheet's configuration mode table. Also, ensure nCONFIG is properly driven (not floating) at power-up; a floating nCONFIG can leave the device in an unconfigured state and prevent CONF_DONE from asserting.

Route JTAG signals (TCK, TMS, TDI, TDO) with 50 ohm controlled impedance if boundary-scan testing is required, and keep them away from fast-switching I/O to avoid noise coupling. Place the EPC1/EPC1064/EPC1213/EPC1441 configuration device within 2 inches of the FPGA with short, parallel DATA0/DCLK traces to minimize skew and improve configuration reliability.
