EPF81500AQC240-4 Übersicht
An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all defined by SRAM configuration bits loaded at power-up. Within the programmable logic hierarchy, an FPGA sits above CPLDs (which use non-volatile EEPROM/flash configuration and have lower density) and below fixed-function ASICs (which offer higher density at the cost of no reconfigurability). FPGAs bridge prototyping and production: they deliver ASIC-class integration with mask-change-free design revisions, making them indispensable for telecom, industrial control, and DSP pipelines.
Key features include 1,296 logic cells, up to 16,000 usable gates, four phase-locked loop (PLL)-style clock networks via the FLEX 8000 row/column architecture, JTAG-based boundary-scan testing, MultiVolt I/O for mixed-voltage buses, and SRAM configuration that supports parallel EPROM, serial EEPROM (EPC1, EPC1064, EPC1213, EPC1441), or microcontroller loading. The -4 speed grade indicates a faster bin than the -3, -2, or -1 grades.
The FLEX 8000 architecture combines a fine-grained logic element (LE) array with continuous routing channels and a predictable delay model, which simplifies static timing closure. The device is built on a 0.42 µm five-layer metal CMOS process that integrates configuration SRAM, logic, and I/O on a single die, eliminating the need for external configuration logic beyond the boot EEPROM.
Typical applications for the EPF81500AQC240-4 include telecommunications line-card glue logic, industrial control and factory automation state machines, DSP preprocessing pipelines, legacy PCI bus bridges, and instrumentation front-ends. The wide 240-pin footprint provides ample I/O for parallel buses and SRAM/DRAM interfaces.
When designing with this part, engineers should select an EPC-series configuration device to match the FLEX 8000 serial/parallel boot protocol, leave guard bands around all 181 I/O pins to accommodate signal integrity on parallel buses, and confirm the -4 speed grade against downstream timing budgets (a -3 or -2 grade may suffice if 125 MHz is not required).

Typische Anwendungen
EPF81500AQC240-4 ist geeignet für 6 Anwendungs: Telecommunications Line-Card Glue Logic, Industrial Control and Factory Automation, DSP Preprocessing Pipelines, Legacy PCI Bus Bridges and Adapters, Test and Measurement Instrumentation, Embedded System Glue Logic and Bus Arbitration.
Telecommunications Line-Card Glue Logic
The EPF81500AQC240-4 is well suited to telecommunications line-card glue logic where it bridges parallel TDM buses, performs protocol conversion between E1/T1 framers and backplane ASICs, and runs low-rate state machines. Its 181 user I/O pins expose ample parallel bus width for 16- or 32-bit datapaths without external muxes, while the -4 speed grade's 125 MHz capability comfortably accommodates 8.192 MHz E1 and 1.544 MHz T1 bitstreams with timing margin to spare. The MultiVolt I/O feature lets the FPGA sit between 5 V framer logic and 3.3 V backplane transceivers without level shifters. Configuration is held in an EPC1441 serial EPROM, simplifying in-system firmware updates via JTAG during factory provisioning and field maintenance cycles.
Empfohlen
Industrial Control and Factory Automation
In industrial control cabinets, the EPF81500AQC240-4 implements deterministic PLC-style state machines, encoder/counter decoding, and motor-control sequencing. Its 1,296 logic cells support 10-20 concurrent finite-state machines plus PWM generation and quadrature decoding, while the 181 I/O drive 24 V optically-isolated field-side signals via on-board buffers. The 5 V core and MultiVolt I/O let the part sit next to legacy 5 V sensors and 3.3 V ARM Cortex MCUs without glue logic. Designers typically load configuration from an EPC1064 over the serial interface and use JTAG for in-circuit verification during machine commissioning. The 0 °C to +70 °C commercial temperature range covers most factory-floor enclosures.
Empfohlen
DSP Preprocessing Pipelines
The EPF81500AQC240-4 serves as a front-end for DSP preprocessing in audio base stations, sonar signal conditioning, and instrumentation front-ends. Its 1,296 logic cells implement FIR filters, FFT pre-processing, sample-rate conversion, and gain control ahead of an external DSP or ASIC. The 125 MHz operation of the -4 speed grade allows parallel multiply-accumulate (MAC) at sample rates up to ~25 MHz with 16-bit coefficients, while the 16,000 usable gates handle several cascaded biquad stages. The wide 240-BFQFP footprint exposes enough I/O for parallel 16-bit ADC/DAC buses plus JTAG, status LEDs, and host interrupts on a single chip.
Empfohlen
Legacy PCI Bus Bridges and Adapters
Legacy PCI add-in cards, particularly those designed in the late 1990s and early 2000s, use the EPF81500AQC240-4 as a 32-bit/33 MHz PCI target or master bridge to legacy ISA, VME, or proprietary backplanes. Its 1,296 cells and 16,000 usable gates implement the PCI configuration space, target/master state machines, and FIFO handshaking on a single device. The 240-BFQFP's 181 I/O pins drive the 32-bit PCI bus plus parity, interrupt, and GPIO signals with no external muxes. New PCI designs target the -4 speed grade; maintenance spares often drop in the -3 grade at lower cost.
Empfohlen
Test and Measurement Instrumentation
Test and measurement instruments such as logic analysers, protocol exercisers, and modular data-acquisition systems use the EPF81500AQC240-4 for timing generation, pattern generation, and front-panel control. The 181 user I/O fan out to connectorised test points, while 1,296 cells implement 32-bit pattern sequencers and timing-edge generators. The -4 speed grade's 125 MHz capability drives 100 MHz pattern clocks with deterministic jitter from the FLEX 8000 PLL clock network. MultiVolt I/O lets the same board talk to 3.3 V CMOS logic analysers and 5 V TTL instrumentation simultaneously. JTAG boundary scan accelerates board-level test bring-up.
Empfohlen
Embedded System Glue Logic and Bus Arbitration
The EPF81500AQC240-4 is a common glue-logic choice for embedded systems that integrate PowerPC, MIPS, or ARM processors with peripheral ASICs, SRAM, and Flash memories. Its 1,296 cells implement bus arbiters, address decoding, wait-state generators, and interrupt controllers on a single chip, replacing dozens of 74-series logic devices. The 240-BFQFP's 181 I/O accommodate 32-bit address/data buses plus chip-select, DMA, and interrupt lines. Designers typically boot from an EPC1441 serial EPROM that holds both the FLEX 8000 bitstream and a small bootloader for the host CPU. The MultiVolt I/O bridges 5 V processor buses and 3.3 V peripheral ASICs without external transceivers.

Wichtigste Unterscheidungsmerkmale
- Highest speed grade in the EPF81500A 240-BFQFP family (vs. EPF81500AQC240-3)
- Maximum logic density in the FLEX 8000 240-BFQFP package (vs. EPF81188AQC240-4)
- MultiVolt I/O for mixed-voltage system design (vs. EPF81500AQC240-2N)
Designhinweise
Estimated: at VCCINT = 5.0 V with the FLEX 8000 EPF81500A running 100% utilisation at 125 MHz, ICC draws around 250-300 mA (approximately 1.25-1.5 W). Bulk-decouple VCCINT with a 100 µF tantalum plus 0.1 µF ceramic per supply pin cluster, and place 10 µF ceramics at each VCCIO bank. The MultiVolt I/O feature means separate VCCIO rails for 3.3 V and 5.0 V banks; do not float unused VCCIO pins. Power-on ramp should be monotonic within 1 ms to avoid configuration SRAM corruption.
The 240-BFQFP package has 0.5 mm pitch gull-wing leads that require careful PCB layout: use 0.15 mm/0.20 mm land patterns with NSMD (non-solder mask defined) pads for best solder joint reliability. Route all 181 user I/O on inner layers with 50 Ω controlled impedance, keep length matching within 25 mils for parallel buses, and place the configuration EPROM (EPC1/EPC1064/EPC1213/EPC1441) within 50 mm of the nCONFIG pin to keep the serial configuration path short and noise-free.
Do not confuse the EPF81500A (FLEX 8000, SRAM-based, 5 V) with the EPF81500 (original FLEX 8000, no 'A' suffix) - the 'A' revision uses the 0.42 µm process and MultiVolt I/O but otherwise shares the same datasheet. Also note that the EPF81188A is a logic-reduced member of the same family with only 12,000 usable gates; designs targeting the EPF81500A's 1,296 cells will not fit. Finally, the obsolete lifecycle status means new designs should consider Cyclone-series equivalents with appropriate PCB rework.
Compliance-Informationen
Original Altera FLEX 8000 family predates widespread RoHS compliance mandates; the '-2N' suffix variants indicate lead-free terminal finish. RoHS and REACH compliance status are not stated in the verified distributor data and are marked [DATA_NEEDED] in specs. AEC-Q100 is not applicable since this is a commercial-grade FPGA with 0-70 °C operating range.
