EPF6024AQI240-1 Overview
A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and programmable I/O cells, allowing designers to implement custom digital circuits after fabrication. FPGAs sit above ASICs and CPLDs in flexibility: they offer higher logic density than CPLDs while remaining re-programmable, making them ideal for prototyping, low-volume production, and applications where standards or protocols may evolve. The FLEX 6000 family specifically targets cost-sensitive glue-logic and bus-interface designs with SRAM-based configuration.
Key features of the EPF6024AQI240-1 include 4 dedicated input pins, 199 bidirectional I/O pins, on-chip SRAM-based configuration memory, JTAG-based IEEE 1149.1 boundary-scan test support, and multi-voltage I/O support for interfacing with 3.3V and 5.0V devices. The 240-pin PQFP package uses a 0.500 mm terminal pitch and provides a fine-pitch surface-mount form factor suitable for moderate-density designs.
The device is built on a CMOS SRAM process and is configured via a serial configuration EPROM or microprocessor interface. Its 4-input look-up table (LUT)-based logic elements and FastTrack interconnect deliver predictable timing with pin-to-pin logic delays in the low nanosecond range, enabling high-speed state machines and datapath functions.
Typical applications include PCI bus interfaces, peripheral bridging, DSP co-processing front-ends, telecommunications line-card glue logic, and industrial control system integration. Its 199 I/O make it well suited to wide-bus multiplexing and protocol conversion.
When designing with this FPGA, ensure proper decoupling (0.1 uF ceramic per VCC pin group), adherence to the multi-voltage I/O sequencing requirements, and provision for a configuration EPROM or microcontroller-based configuration loader. Industrial-grade parts require careful thermal management in enclosed enclosures.

Typical Applications
EPF6024AQI240-1 is suitable for 6 applications: PCI Bus Interface Glue Logic, Peripheral Bridging and Protocol Conversion, Telecom Line-Card Glue Logic, DSP Co-Processing Front-End, Industrial Control System Integration, Legacy Peripheral Card Refresh.
PCI Bus Interface Glue Logic
The EPF6024AQI240-1's 199 user I/O and 172 MHz maximum clock frequency make it well suited for PCI bus interface glue logic between processors, memory, and peripherals. PCI 2.1 requires 33 MHz operation with 32-bit or 64-bit bus widths, well within the device's 172 MHz Fmax and 199 I/O budget. The SRAM-based configuration allows late-stage pin-out changes without board re-spin, ideal for evolving peripheral cards where pin assignments may change during design. Place the FPGA between the PCI bus and local ASIC/ASSP glue, leveraging multi-voltage I/O for 3.3V/5V signal compatibility. Designers should reserve configuration pins for the serial configuration EPROM.
Recommended
Peripheral Bridging and Protocol Conversion
With 199 I/O and SRAM-based reconfigurability, the EPF6024AQI240-1 excels at bridging legacy peripherals to modern processors. The 4 dedicated inputs plus 199 bidirectional I/O provide ample headroom for simultaneous UART, SPI, I2C, and parallel bus interfaces. Industrial temperature grade (-40C to +85C) supports factory floor and outdoor deployments where consumer-grade parts fail. The device's high I/O count eliminates the need for external bus expander chips. Place decoupling capacitors within 5 mm of every VCC pin group and route configuration signals away from high-speed switching nets.
Recommended
Telecom Line-Card Glue Logic
Telecom line cards require deterministic glue logic for TDM bus multiplexing, clock distribution, and framer interfacing, all of which fit the EPF6024AQI240-1's 24K-gate capacity. The 172 MHz Fmax supports high-speed serial backplane links and ATM/SONET framer glue without timing closure issues. Industrial temperature grade ensures operation in thermally uncontrolled central-office environments. The SRAM-based configuration allows field firmware upgrades via JTAG without board removal, valuable for telecom maintenance windows. Multi-voltage I/O simplifies interfacing with legacy 5V line-card components.
Recommended
DSP Co-Processing Front-End
The EPF6024AQI240-1's 172 MHz Fmax and 199 I/O make it suitable as a DSP co-processing front-end, pre-processing data streams before handing off to a dedicated DSP chip. The device can implement custom FIR filters, data formatting, and DMA control logic at wire speed. Its 4 dedicated inputs handle high-fanout clock and enable signals cleanly, while 199 user I/O support wide parallel data paths. SRAM configuration enables algorithm updates without hardware revision, ideal for evolving DSP firmware. Use the device to offload I/O-intensive tasks from the DSP, freeing DSP cycles for arithmetic.
Recommended
Industrial Control System Integration
Industrial control systems integrate sensors, actuators, motor controllers, and human-machine interfaces, all of which can be unified by the EPF6024AQI240-1's 199 I/O and industrial temperature grade. The device handles encoder quadrature decoding, PWM generation, and fieldbus protocol bridging in a single chip, replacing multiple discrete logic ICs. SRAM configuration enables factory-floor firmware updates for product line variants without hardware changes. The 24K-gate capacity supports complete state machines for machine sequencing and safety interlocking. Industrial -40C to +85C operation tolerates unheated enclosures.
Recommended
Legacy Peripheral Card Refresh
Refreshing obsolete peripheral cards for legacy systems is a classic application for the EPF6024AQI240-1. The FPGA replaces discontinued ASICs and gate arrays on existing PCBs, restoring manufacturing capability for end-of-life industrial, military, or telecom systems. Its 240-pin PQFP package matches the footprint of many legacy ASIC designs, minimizing board rework. SRAM configuration enables last-minute bug fixes without respinning the silicon. Engineers can capture legacy logic in HDL, verify in simulation, and program the FPGA to recover production. Industrial temperature grade preserves environmental specifications.

Key Differentiators
- Industrial temperature grade (-40C to +85C) (vs EPF6024AQC240-1)
- Standard speed grade (-1) for design margin (vs EPF6024AQI240-3)
- High I/O count (199) for bus-intensive designs (vs EPF6016AQI208-1)
Design Notes
The EPF6024AQI240-1 requires separate VCCINT (core) and VCCIO (I/O) supply rails; both must be decoupled with 0.1 uF ceramic capacitors placed within 5 mm of every supply pin group, plus bulk decoupling (10-100 uF tantalum or aluminum polymer) on each rail. Power sequencing requires VCCINT to reach stable regulation before VCCIO ramps, or I/O pins may drive into unpowered logic and cause latch-up. Estimate total core current at approximately 100-300 mA typical depending on utilization and clock rate.
Estimated: at 100% resource utilization and 172 MHz operation, the EPF6024AQI240-1 dissipates approximately 1-2 W internally; the 240-pin PQFP package has relatively high theta_JA (approximately 30-40 C/W in still air), so a junction temperature rise of 30-80 C above ambient is expected. For industrial applications in enclosed housings, provide copper pours on inner PCB layers and consider airflow. Avoid placing heat-generating components directly above the FPGA.
Route configuration signals (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) away from high-speed switching nets and keep them short to minimize crosstalk. Place the configuration EPROM (EPC1/EPC2) within 50 mm of the FPGA for reliable serial configuration. Use a 4-layer PCB with continuous ground plane beneath the FPGA for signal integrity and EMI suppression. The 0.500 mm pin pitch requires fine-pitch SMT assembly capability and inspection.
Common pitfalls when designing with this part include: (1) forgetting to connect MSEL pins for proper configuration mode selection, (2) leaving JTAG pins floating which can cause spurious configuration triggers, (3) underestimating configuration time at power-up which can be 50-200 ms depending on EPC size, (4) ignoring the nCONFIG/nSTATUS handshaking which prevents configuration errors, and (5) assuming SRAM-based configuration persists through power cycles (it does not). Always include a configuration EPROM or processor bootloader.
Compliance Information
EPF6024AQI240-1 is obsolete and the original RoHS/REACH compliance status is not documented in the verified web data. The 'N' suffix in similar EPF6024AQC240-3N typically denotes lead-free / RoHS-compliant parts. AEC-Q100 not applicable (industrial FPGA, not automotive-grade). Engineers should request material declarations from distributors before volume orders.
