EPF6024AQI240-1N Overview
FLEX 6000 devices belong to the broader hierarchy of Programmable Logic Devices (PLD), which sit between fixed-function ASICs and general-purpose microcontrollers in the digital logic spectrum. As a Field Programmable Gate Array (FPGA), the FLEX 6000 family implements arbitrary combinational and sequential logic via a lookup-table (LUT) based architecture with embedded SRAM configuration memory. Unlike one-time-programmable (OTP) antifuse FPGAs, FLEX 6000 parts are SRAM-based and can be reconfigured in-circuit thousands of times, which makes them suitable for prototyping and design-iteration workflows.
Key features of the EPF6024AQI240-1N include 4 dedicated inputs, 199 bidirectional I/O lines organized in banked groups supporting multiple I/O standards, and an industrial operating temperature range. The PQFP-240 package provides a 0.500 mm terminal pitch in a square fine-pitch flatpack form factor. The 'I' speed grade places it in the mid-range of FLEX 6000 timing, while the 'N' suffix indicates a lead-free (Pb-free) assembly.
Architecturally, the FLEX 6000 family uses Altera's Lab/Embedded Array Block structure. Each Logic Array Block (LAB) contains ten Logic Elements, each consisting of a 4-input LUT, a programmable register, and dedicated carry chain logic for arithmetic operations. This architecture makes the EPF6024 well-suited for high-speed glue logic, register-intensive datapath functions, and interface bridging applications.
Typical applications include telecommunications line cards, industrial control systems, peripheral interface bridging, and legacy ASIC replacement. The 172 MHz internal clock rate supports common protocols such as PCI, UART, and high-speed parallel buses.
When designing with this device, ensure that the JTAG chain is properly terminated and that configuration data is sourced from a stable EEPROM or processor. Designers should also verify that downstream tools (Quartus II or MAX+PLUS II) support the device before starting a new project.

Typical Applications
EPF6024AQI240-1N is suitable for 7 applications: Telecommunications Line Card Glue Logic, Industrial Control System Interface Bridging, Legacy ASIC Replacement, Peripheral Interface Expansion (PCI / ISA), Prototype and Evaluation Platform, Avionics / Defense Legacy Retrofit, Test and Measurement Instrumentation.
Telecommunications Line Card Glue Logic
The EPF6024AQI240-1N is well-suited to telecommunications line card glue logic because of its 1,960 logic elements and 199 user I/Os, which can absorb multiple discrete 74-series logic devices into a single programmable chip. Its 172 MHz fMAX handles high-speed bus arbitration and protocol conversion tasks between network processors and backplane interfaces. The JTAG interface enables rapid in-system reprogramming during board bring-up. Designers route critical timing paths through dedicated LAB carry chains and use the device's bidirectional I/O banks to support LVTTL, LVCMOS, and PCI signalling on a single die, reducing bill-of-materials cost.
Recommended
Industrial Control System Interface Bridging
Industrial controllers often require bridging between legacy parallel buses (ISA, PC/104) and modern serial interfaces (SPI, I2C, UART). The EPF6024AQI240-1N's 199 I/O pins support up to 24 parallel data bits plus extensive control signalling in a single device, while its 0.35 micron CMOS design tolerates industrial temperature ranges. The 172 MHz clock supports deterministic protocol translation with measured deterministic latency. Designers often implement 8-bit bus-to-UART bridges or stepper-motor pulse generators on FLEX 6000 parts because the LUT-based architecture easily maps finite state machines.
Recommended
Legacy ASIC Replacement
The EPF6024AQI240-1N provides a cost-effective replacement for aging CMOS ASICs in low-volume or end-of-life products. Designers map the original gate-level netlist to the FLEX 6000 LUT fabric and verify timing against the legacy timing model. The SRAM-based configuration allows last-minute design changes without mask revisions, and the JTAG interface supports field updates. With 1,960 logic elements, the EPF6024 covers most glue-logic ASICs up to about 24,000 gates, and the PQFP-240 footprint offers a like-for-like pin-for-pin path on most legacy PCBs.
Recommended
Peripheral Interface Expansion (PCI / ISA)
The EPF6024AQI240-1N's 172 MHz maximum internal clock supports PCI 33 MHz peripheral designs with timing margin, and its 199 I/O lines accommodate full 32-bit PCI plus auxiliary control signals. The Lab/Embedded Array architecture includes dedicated carry chains that accelerate address decoding and bus arbitration logic. The 5V-tolerant I/O bank (industrial temperature grade) interoperates with legacy 5V PCI backplanes commonly found in industrial PCs and embedded systems. Designers pair the EPF6024 with a host processor or DMA controller to add custom peripherals without expanding the host's native interface.
Recommended
Prototype and Evaluation Platform
Because FLEX 6000 devices support in-system reprogramming through JTAG, the EPF6024AQI240-1N is frequently used in research labs and university digital-design courses. Students and engineers can iterate on logic designs in minutes rather than waiting for board spins, and the same hardware can host many sequential lab exercises. The PQFP-240 package is breadboard-compatible through QFP-to-DIP adapters, allowing rapid mechanical prototyping. The 172 MHz clock is fast enough to demonstrate CPU datapath exercises, pipelined multipliers, and small RISC cores.
Recommended
Avionics / Defense Legacy Retrofit
Defense and avionics platforms with field lifetimes measured in decades often contain FLEX 6000-based subsystems that require identical replacement parts for repair. The EPF6024AQI240-1N's industrial temperature range, lead-free termination (N suffix), and PQFP-240 package match the original assembly footprint and qualification requirements. Repair depots source obsolete FPGAs through authorized distributors to keep flight-critical systems operational. The device's deterministic LUT-based architecture supports verification flows required by DO-254 design assurance guidelines.
Recommended
Test and Measurement Instrumentation
Test instruments often use FPGAs for high-speed pattern generation, custom protocol decoding, and time-interval measurement. The EPF6024AQI240-1N's 199 I/Os accept many simultaneous measurement channels, while the 172 MHz internal clock supports time-domain measurements with sub-microsecond resolution. The JTAG chain allows automated self-test on power-up and field firmware updates. Designers pair the EPF6024 with precision ADCs and DACs to build custom logic analyzers, protocol exercisers, or production-line test fixtures.

Design Notes
Estimated: at 172 MHz operation across all 1,960 logic elements with typical 50 percent toggle rate, the EPF6024AQI240-1N draws roughly 200-400 mA from VCCINT. Designers should provide a low-impedance 3.3 V regulator (or 5 V for legacy PCI variants) with at least 10 uF of bulk decoupling plus 0.1 uF high-frequency bypass at every VCC pin pair. The device's SRAM configuration memory requires stable power during programming and operation - voltage droops below 3.0 V can corrupt configuration and cause functional failure. Always sequence VCCIO after VCCINT to prevent I/O latch-up during power-up.
PQFP-240 packages with 0.500 mm terminal pitch demand careful PCB layout. Use 0.15 mm wide traces with 0.15 mm spacing entering the gull-wing leads, and fan out on inner layers with via-in-pad if board density permits. The exposed die paddle is not present on PQFP (only on QFN variants), so thermal dissipation relies on copper pours on top and inner layers. Maintain a continuous ground plane under the device to provide a low-impedance return path for high-speed signals and to reduce EMI. JTAG TMS, TCK, TDI, TDO traces should be length-matched within 25 mm to avoid programming failures.
Do not substitute EPF6024 variants with different speed grades (-1 vs -2 vs -3 vs -4) without re-running timing closure on the existing bitstream - lower speed grades can fail hold-time analysis on critical paths. Also note that 'C' suffix denotes commercial (0C to +70C) while 'I' denotes industrial (-40C to +85C); substituting a 'C' variant into an industrial environment voids reliability assumptions. Finally, FLEX 6000 configuration is volatile: power interruptions during operation will lose the design state, so design for fail-safe JTAG reload or use a watchdog supervisor.
At 172 MHz internal operation, signals switching faster than 100 MHz should be routed as microstrip or stripline with controlled impedance (50 ohm single-ended, 100 ohm differential). Keep clock and JTAG signals at least 3W away from other switching traces and use guard traces to ground on both sides. The PQFP-240 lead inductance is roughly 2-5 nH per pin, so high-speed outputs should be series-terminated at the source when driving more than 50 mm of trace. Decoupling capacitors must be placed within 5 mm of each VCC pin pair for effective high-frequency noise suppression.
Compliance Information
Lead-free (Pb-free) assembly confirmed by 'N' suffix per Altera ordering information. RoHS compliance assumed for lead-free variants; reach, halogen-free, and conflict-mineral data not available in the verified web data and marked unknown.
