EPF6024AQI240-2 Overview
A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing channels, and programmable I/O cells. FPGAs sit at the top of the digital logic hierarchy: they are reprogrammable ASIC alternatives that bridge the gap between fixed-function Application-Specific Integrated Circuits and software-driven processors. The FLEX 6000 family specifically targets low-cost, high-volume glue-logic and bus-interface applications.
Key features of the EPF6024AQI240-2 include 16 logic elements (LEs), embedded array blocks (EABs) for memory implementation, fast wide-decoder capability, multi-volt I/O support, and JTAG-compliant boundary-scan testing. The 'I' suffix denotes the industrial temperature grade (-40C to +85C), while 'Q' indicates the PQFP package, '240' is the pin count, and '-2' marks the speed grade. The device operates from a 3.3 V core supply with 5.0 V I/O tolerance, satisfying low-power requirements for notebook computers and battery-operated equipment.
The FLEX 6000 architecture combines a continuous, high-performance routing network with fine-grained logic elements, enabling predictable timing closure for designs up to 24,000 gates. Its 4 dedicated input pins feed the global clock and clear networks, while the 199 user I/Os can be configured per-pin as input, output, or bidirectional with slew-rate control and tri-state buffering.
Typical applications for the EPF6024AQI240-2 include glue-logic integration on legacy 5V/3.3V motherboards, PCI bus interfaces, peripheral controllers, telecommunications line cards, digital signal processing co-processors, and industrial control systems where the industrial temperature range is required. The PQFP-240 footprint remains widely supported by through-hole-compatible socket adapters for prototyping.
When designing with this FPGA, ensure that the Quartus II or MAX+PLUS II design toolchain matches the '-2' speed grade in the device selection. The configuration scheme (PS, PPS, or JTAG) must be selected during board design because FLEX 6000 devices do not retain configuration when power is removed - a separate configuration memory device is required.

Typical Applications
EPF6024AQI240-2 is suitable for 7 applications: Legacy 5V/3.3V Motherboard Glue Logic, PCI Bus Interface Controller, Telecommunications Line Card, Industrial Control and Factory Automation, Data Acquisition System Front-End, Digital Signal Processing Co-Processor, Peripheral Controller and Embedded I/O Expansion.
Legacy 5V/3.3V Motherboard Glue Logic
The EPF6024AQI240-2 is well-suited for legacy motherboard glue-logic replacement because its 199 user I/Os and 5.0 V I/O tolerance allow direct interfacing with ISA-bus peripherals, PS/2 controllers, and Super-I/O chips without external level shifters. With 12,000-24,000 usable gates, it can replace 5-10 discrete PAL/GAL devices plus several TTL bus buffers, reducing board area and BOM cost. The PQFP-240 footprint and -2 speed grade at 153 MHz Fmax provide sufficient timing margin for bus-arbitration logic. Designers migrating from older AMD MACH or Xilinx XC9500 designs can reuse existing PCB layouts because the Altera FLEX 6000 pinout preserves standard JTAG pins (TCK, TMS, TDI, TDO) for in-system programming. Industrial temperature grade ensures operation in chassis with restricted airflow.
Recommended
PCI Bus Interface Controller
PCI 2.1 bus interfaces running at 33 MHz require precise timing and 5V signaling, both of which the EPF6024AQI240-2 supports natively through its 5V-tolerant I/O banks. The 1,960 registers and embedded array blocks (EABs) provide enough logic density to implement target or master state machines, address decoding, parity generation, and 32-bit datapath control in a single device. The -2 speed grade at 153 MHz Fmax provides comfortable timing margin for 33 MHz PCI operation with up to 70% utilization. Compared to discrete 74-series logic implementations, this FPGA reduces the bus interface to a single chip with reconfigurable personality, enabling hardware revisions via JTAG without PCB rework.
Recommended
Telecommunications Line Card
The 24K-gate EPF6024AQI240-2 provides the right balance of logic density, I/O count, and industrial temperature grade for telecommunications line-card applications including T1/E1 framers, HDLC controllers, and time-slot interchangers. With 199 user I/Os, it can interface directly to multiple E1 transceiver chips, framer ICs, and backplane serializers without external bus switches. The CMOS SRAM architecture enables field upgrades via JTAG, which is critical for telecom equipment that must support protocol revisions over a 15-20 year service life. The 5V-tolerant I/Os simplify interface to legacy telecom ASICs operating from 5V rails.
Recommended
Industrial Control and Factory Automation
Industrial PLCs and motion controllers benefit from the EPF6024AQI240-2's industrial -40C to +85C temperature range and 199 I/O count for parallel interface to stepper motor drivers, encoder counters, and opto-isolated digital I/O modules. The FPGA can consolidate multiple encoder counters, PWM generators, and PID controller blocks into a single device, replacing 3-5 dedicated counter/timer ICs. Its SRAM-based programmability allows field reconfiguration when production lines changeover, and JTAG access simplifies in-system firmware updates without removing boards from service. The 153 MHz Fmax is more than adequate for 100 kHz servo loop rates typical in stepper motor control.
Recommended
Data Acquisition System Front-End
The EPF6024AQI240-2 serves as a programmable front-end for multi-channel data acquisition systems, handling channel multiplexing, sample-clock generation, and parallel-to-serial conversion before data enters the host processor. With 199 user I/Os, it can directly address 16-32 analog input channels through parallel-addressable ADC muxes and manage simultaneous-sampling clock trees. The embedded array blocks (EABs) can implement small FIFO buffers for burst-mode ADC capture. Industrial temperature grade supports outdoor or factory-floor deployment without additional thermal management.
Recommended
Digital Signal Processing Co-Processor
For moderate-complexity DSP tasks such as FIR filtering, FFT pre-processing, or custom data transformations, the EPF6024AQI240-2's 24K gates and 153 MHz Fmax enable 16-bit fixed-point multiply-accumulate operations at sample rates up to ~10 MSPS when implemented across multiple logic elements. The parallel architecture outperforms microcontrollers for deterministic-latency DSP while costing less than full ASIC implementations. Embedded array blocks (EABs) provide efficient implementation of coefficient tables and small dual-port RAMs for sample buffers. Industrial temperature grade supports outdoor DSP applications such as audio processing in industrial PA systems.
Recommended
Peripheral Controller and Embedded I/O Expansion
The EPF6024AQI240-2 can consolidate multiple legacy peripheral controllers (UART, parallel port, IDE, floppy) into a single programmable device, which was a primary use case when the FLEX 6000 family was introduced in the late 1990s. With 199 user I/Os, it can replace 4-6 dedicated peripheral controller ICs while adding custom protocol extensions. The 5V I/O tolerance maintains compatibility with original PC/AT peripherals. Designers can use the FLEX 6000 to bridge modern 3.3V processors to legacy 5V peripherals, simplifying embedded system upgrades.

Design Notes
The EPF6024AQI240-2 requires a 3.3V VCCINT core supply and a separate VCCIO bank supply that can be either 3.3V or 5.0V depending on the I/O interface. Decoupling requirements call for at least 8x 0.1uF ceramic capacitors placed within 5mm of each VCCINT pin cluster, plus 2x 10uF tantalum bulk capacitors on the VCCIO rail. Estimated: at 50 MHz toggle rate with 60% utilization, total current draw is approximately 300-400 mA on VCCINT and 100-150 mA on VCCIO, so a 1.5A-rated LDO is recommended for VCCINT to provide adequate transient response during configuration bitstream loading.
The PQFP-240 package with 0.500 mm terminal pitch requires careful PCB layout to avoid solder bridging. Recommended land pattern uses 0.30 mm pad width with 0.20 mm spacing; a 0.1 mm solder mask dam is the practical minimum for production. Thermal performance is limited by the plastic package - at full 1.5 W dissipation the junction-to-ambient thermal resistance is approximately 35-40 C/W, so no external heatsink is required but at least 4 thermal vias under the die-attach pad improve long-term reliability.
FLEX 6000 devices are SRAM-based and lose configuration when power is removed - a configuration memory device (EPC2, EPC4, or compatible flash) or JTAG programmer must be present on the board for the FPGA to function at power-up. Also, the Quartus II software does not allow bitstream porting between speed grades (e.g., a -2 design will not load into a -1 device even though they share the same die), so substituting the EPF6024AQI240-1 (speed grade -1) requires recompilation with the new device selected.
Place the EPC2 configuration memory within 50 mm of the FPGA DATA0/DCLK/nCONFIG/nSTATUS pins to avoid signal integrity issues. Use 4-layer PCB with continuous ground plane under the FPGA to control return-current paths for the 199 I/O signals switching simultaneously. Dedicated clock input pins (CLK0/CLK1/CLK2/CLK3) should be routed with controlled impedance (50 ohm microstrip) and length-matched if used for source-synchronous interfaces.
Compliance Information
RoHS, REACH, lead-free, and halogen-free status could not be confirmed from the verified web data. The EPF6024AQI240-2 was introduced in the late 1990s before RoHS directives became mandatory in 2006, so most original material is non-RoHS. Newer shipments with '-N' suffix variants (e.g., EPF6024AQC240-2N) are more likely to be Pb-free, but buyers should request specific compliance documentation from the distributor before placing orders.
