EPF81500ARI240-3 Présentation

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.

Applications typiques

EPF81500ARI240-3 convient pour 6 applications: Industrial Control Glue Logic, Telecommunications Bus Bridge, Embedded Processor Peripheral Expansion, Legacy Replacement of Discrete SSI/MSI Logic, Test and Measurement Front-End, Aerospace and Defense Avionics Interfaces.

🏭

Industrial Control Glue Logic

The EPF81500ARI240-3's 16,000 usable gates and 181 user I/O make it well-suited for industrial control glue-logic applications where it bridges microcontrollers to legacy peripherals, decodes address lines, and generates timing waveforms. Its 5 V I/O tolerance simplifies interfacing with classic TTL/CMOS sensors, optocouplers, and motor-driver ICs typical of factory-floor designs. The exposed pad on the RQFP-240 package aids thermal dissipation for continuously switching outputs. Source: FLEX 8000 industrial reference designs.

🌐

Telecommunications Bus Bridge

The EPF81500ARI240-3's 125 MHz maximum internal clock and 181 I/O enable telecom bus-bridge designs that translate between parallel backplanes, serial links, and processor buses. Its register-rich architecture efficiently implements byte-parity logic, FIFO buffers, and protocol state machines. The 240-pin RQFP provides enough I/O to bridge legacy 8/16/32-bit buses concurrently, reducing board area versus discrete SSI/MSI logic.

🖥️

Embedded Processor Peripheral Expansion

The EPF81500ARI240-3 expands embedded processor I/O count and adds custom peripherals without redesigning the processor board. Engineers offload I/O expansion, timer/counter banks, PWM generators, and interrupt controllers to the FPGA, freeing processor pins and reducing CPU cycle overhead. Its in-circuit reconfigurability via EPC1/EPC1441 allows firmware-style updates to peripheral logic in the field, simplifying end-product maintenance.

🔧

Legacy Replacement of Discrete SSI/MSI Logic

The EPF81500ARI240-3 consolidates dozens of 74-series TTL/MSI packages - decoders, multiplexers, counters, and latches - into a single programmable device, dramatically reducing PCB area, power, and assembly cost. Its 16K usable gates accommodate designs that previously required multiple logic boards, and the JTAG/boundary-scan support simplifies board-level test. The 5 V supply matches classic TTL power rails, easing migration of legacy boards.

🎥

Test and Measurement Front-End

The EPF81500ARI240-3 implements custom measurement front-ends - pattern generators, counter banks, trigger logic, and timing sequencers - where its 125 MHz fMAX and 181 I/O enable multi-channel stimulus and capture. Its deterministic FastTrack interconnect simplifies timing analysis for T&M designs requiring repeatable edge placement. Legacy T&M equipment widely uses FLEX 8000 parts in long-life programs where redesign costs outweigh modern migration.

✈️

Aerospace and Defense Avionics Interfaces

The EPF81500ARI240-3 continues to serve long-life aerospace and defense programs because avionics and MIL-spec systems often retain FLEX 8000 designs for 20+ years to avoid re-certification costs. The 240-pin RQFP package and 5 V I/O tolerance match legacy ARINC 429, MIL-STD-1553, and discrete interface circuits. Obsolete-stock distributors maintain qualified inventories for these programs; design notes call for additional component-level screening.

The EPF81500ARI240-3 typically prices between 60 USD per unit at 1,000-piece break and 95 USD per unit at single-piece break as of 2026-09-12, based on aggregated distributor quotes. Premium distributors such as DigiKey list stock at the upper end of this band, while Asian brokers often price below it. Always request a current quote because obsolete-stock prices fluctuate significantly with market availability.
What configuration devices are compatible with EPF81500ARI240-3?
The EPF81500ARI240-3 is configured by Altera serial configuration devices EPC1, EPC1064, EPC1213, and EPC1441, or by an industry-standard parallel EPROM driven by an intelligent controller. Because the SRAM configuration memory is volatile, a configuration source must be present at every power-up for proper initialization. Source: Altera FLEX 8000 configuration handbook.
What is the difference between EPF81500ARI240-3 and EPF81500ARC240-3?
Both EPF81500ARI240-3 and EPF81500ARC240-3 are members of the FLEX 8000 family with 16,000 usable gates and 181 I/O in the same 240-pin RQFP package. The numeric speed-grade suffix differs: the 'I' device is the industrial temperature grade, while 'C' denotes commercial. Functionally they are pin-compatible drop-in equivalents with identical logic and timing characteristics within their respective temperature ranges.
What is the difference between EPF81500ARI240-3 and EPF81500ARI240-2?
The numeric suffix indicates speed grade. EPF81500ARI240-3 is the -3 speed grade with 125 MHz maximum internal clock, while EPF81500ARI240-2 is the faster -2 speed grade with higher achievable fMAX. Both share the same RQFP-240 footprint, 16K usable gates, and I/O count, making them pin-compatible but with different timing performance. Choose -2 for tighter timing margins, -3 for lower cost.
What is the best drop-in replacement for EPF81500ARI240-3?
The best drop-in replacements are other FLEX 8000 family members in the same 240-pin RQFP package, namely EPF81500ARC240-3 (commercial temperature grade), EPF81500ARC240-2 (faster speed grade), and EPF81500ARC240-4 (slower speed grade). All share identical pinout, 16K gates, 181 I/O, and 5 V operation. For new designs, however, consider modern Intel Cyclone or MAX series devices.
Where do I download the EPF81500ARI240-3 datasheet?
The official Altera FLEX 8000 datasheet covering EPF81500ARI240-3 is hosted at Intel's Altera documentation archive. Mirrored copies are also available at altersemi.com (https://alterasemi.com/datasheet/alterasemi/EPF81500ARI240-3.pdf) and digchip.com. The datasheet includes DC/AC characteristics, package drawings, configuration schematics, and timing specifications for the FLEX 8000 family.
Where can I find the EPF81500ARI240-3 pinout?
The complete EPF81500ARI240-3 pinout for the 240-pin RQFP package is provided in the FLEX 8000 family datasheet, in the 'Pin Information' and 'Package' sections. Pin assignments include 181 user I/O, dedicated clock inputs (CLK0-CLK3), configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0), JTAG pins (TCK, TMS, TDI, TDO), and power/ground pins distributed throughout the package.
When should I choose EPF81500ARI240-3 over a modern Cyclone FPGA?
Choose EPF81500ARI240-3 only when maintaining a legacy board design that requires 5 V I/O tolerance, exact footprint replacement, or compatibility with an existing FLEX 8000 design flow. For new designs, modern Intel Cyclone IV/V/10 LP FPGAs offer far greater logic density, lower power, modern I/O standards (LVDS, DDR), and active lifecycle support, and are strongly recommended over the obsolete FLEX 8000.
What is the FLEX 8000 architecture used in EPF81500ARI240-3?
The FLEX 8000 architecture used in EPF81500ARI240-3 features a register-rich fine-grained logic element (LE) array connected by a continuous FastTrack interconnect routing network. Each LE contains a 4-input look-up table, a programmable register, and carry/chain logic. The architecture is built on 0.42 µm CMOS SRAM and supports in-circuit reconfigurability via external configuration devices.
What is the best Intel Cyclone equivalent for EPF81500ARI240-3?
The best modern Intel FPGA equivalent for EPF81500ARI240-3 is the Cyclone IV E EP4CE6 or EP4CE10 in a similar TQFP/QFP package family, offering significantly higher logic density, lower 1.2 V core operation, and modern I/O support. However, these are NOT drop-in compatible - they require PCB redesign, new power rails, and updated Quartus tool flow. Use them only for new designs.
Is EPF81500ARI240-3 suitable for new industrial control designs?
For new industrial control designs, EPF81500ARI240-3 is NOT recommended because it is obsolete and supported only via legacy channels, with no long-term availability guarantee. Modern alternatives such as Intel Cyclone IV E, Lattice ECP5, or Microchip PolarFire SoC offer higher logic density, modern toolchains, RoHS compliance, and active lifecycle support, all at lower total cost.

Guide de sélection

Choose EPF81500ARI240-3 when you need a 16,000-gate SRAM-based FPGA in the 240-pin RQFP package with industrial temperature grade for legacy boards, avionics, defense, or industrial control systems. The -3 speed grade at 125 MHz fMAX suits the majority of glue-logic, bus-bridge, and protocol-conversion applications. For commercial-temperature designs, the EPF81500ARC240-3 is a direct drop-in substitute. For designs requiring maximum timing margin, upgrade to the -2 speed grade EPF81500ARC240-2; for cost-sensitive designs with relaxed timing, the -4 grade EPF81500ARC240-4 is acceptable. For new designs, however, prefer modern Intel Cyclone IV or Lattice ECP5 families for active lifecycle support, RoHS compliance, and modern toolchains - the FLEX 8000 family is obsolete.

Notes de conception

The FLEX 8000 family requires a stable 5 V supply on VCCINT and VCCIO with strict tolerance per the datasheet. Place one 0.1 µF ceramic decoupling capacitor adjacent to every VCC pin and one bulk tantalum or electrolytic capacitor (≥ 22 µF) near the package. Power sequencing is not required between VCCINT and VCCIO. Estimated: Icc core current at 125 MHz with high toggle rate typically reaches 200-300 mA per supply rail.

The 240-pin RQFP package has a 0.5 mm lead pitch and a large exposed thermal pad that MUST be soldered to a ground plane for mechanical reliability and thermal performance. Use a 4-layer PCB with continuous ground plane beneath the device, and route all high-speed signals on inner layers to minimize EMI. Keep configuration traces (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) short and away from switching I/O.

Because the FLEX 8000 SRAM configuration is volatile, the configuration source (EPC1, EPC1064, EPC1213, or EPC1441) must be present and operational at every power-up. The configuration clock DCLK should be terminated with a series resistor if the trace exceeds 50 mm. JTAG chain integrity is critical for boundary-scan testing; observe the TCK pull-up requirement documented in the FLEX 8000 handbook.

Common pitfalls include (1) leaving the exposed pad un-soldered, causing thermal and reliability failures; (2) forgetting that all configuration pins must be properly pulled up during normal operation if JTAG is used in passive mode; (3) assuming the device is hot-swappable when in fact SRAM configuration is volatile - the device enters undefined states without a valid configuration; (4) ignoring the I/O voltage tolerance when interfacing with 3.3 V logic.
