EPF6024AQI208-4 Overview
An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs) connected via programmable interconnect, allowing designers to implement custom digital circuits after manufacturing. FPGAs sit in the taxonomy as: PLD -> programmable logic -> FPGA -> SRAM-based FPGA -> FLEX 6000 family. Compared to CPLDs, FPGAs offer higher logic density and richer register-rich architectures but lose non-volatility, requiring an external configuration memory (typically an EPC2 or similar serial PROM).
Key features include 1960 logic elements organized as logic array blocks (LABs), embedded memory blocks, and a maximum clock frequency of 153 MHz. The device supports in-system programming via the FLEX 6000 configuration scheme, supports JTAG boundary-scan testing, and provides tri-state bus-friendly I/O with individually programmable slew-rate and drive-strength control per pin.
The FLEX 6000 architecture employs a four-input LUT-based logic element, FastTrack interconnect for predictable timing, and a continuous routing structure that simplifies place-and-route. Configuration bitstream loads from a serial EPROM or microprocessor interface, and the device supports passive parallel, passive serial, and JTAG configuration modes.
Typical applications include PCI bridge logic, legacy peripheral controllers, telecom line-card glue logic, industrial control boards, and replacement of discrete 74-series TTL/MSI gate arrays in long-lifecycle systems. The wide 171 I/O count suits bus-intensive designs.
When designing with this FPGA, ensure configuration storage is provisioned and verify the speed grade (-4) matches timing closure requirements for the target logic. The -4 speed grade is one of the slower grades; newer logic designs should be verified against timing analysis.

Typical Applications
EPF6024AQI208-4 is suitable for 6 applications: PCI Bridge Glue Logic, Legacy Peripheral Controllers, Telecom Line-Card Glue Logic, Industrial Control Boards, Bus Interface Bridging, Replacement of Discrete 74-Series TTL/MSI.
PCI Bridge Glue Logic
The EPF6024AQI208-4's 1960 LEs and 171 I/O pins make it well suited to PCI 2.2/3.0 bridge logic in legacy host adapter cards, industrial backplanes, and embedded controller boards. Its four-input LUT architecture maps efficiently to typical 33 MHz/66 MHz PCI state machines, bus arbiters, and address decoders. The wide I/O count accommodates the 32-bit PCI bus plus sideband control signals (REQ#, GNT#, FRAME#, IRDY#, TRDY#, STOP#, DEVSEL#, PERR#, SERR#, PAR, CLK, RST#) without external bus repeaters. Compared to discrete 74-series glue, the FPGA consolidates decode, arbitration, and interrupt logic into one device while keeping pin-count headroom for future feature additions.
Recommended
Legacy Peripheral Controllers
Industrial PCs using ISA-bus peripheral cards, parallel-port expansion boards, and SCSI host adapters rely on glue-logic devices like the EPF6024AQI208-4 to bridge microprocessors to slower legacy peripherals. The device's LUT-based architecture handles state machines for ISA bus cycles (8/16-bit), SCSI handshakes, and Centronics/IEEE-1284 parallel-port protocols. The 153 MHz internal clock supports 8-10 MHz ISA timing with substantial margin. Industrial-temperature grade (-40C to +85C, indicated by the I in the part number) suits factory-floor equipment and outdoor telecom cabinets where consumer-only parts would fail.
Recommended
Telecom Line-Card Glue Logic
Telecom line cards in legacy central-office and PBX systems use FLEX 6000 FPGAs to implement T1/E1 framers, HDLC controllers, time-slot interchangers, and DS0/DS1 crosspoint switch control. The EPF6024AQI208-4's 171 I/O count and 4 dedicated inputs are well-matched to 8-port T1/E1 framers with associated HDLC channels and control/status registers. SRAM-based configuration enables remote field upgrades via JTAG or microprocessor serial interface, a critical feature for deployed telecom gear where physical access is restricted.
Recommended
Industrial Control Boards
Factory automation PLCs, motor control boards, and process controllers use the EPF6024AQI208-4 to implement encoder counters, PWM generators, quadrature decoders, and isolated communication bridges. The industrial temperature range and 1960-LE capacity handle multi-axis motion control loops and safety logic consolidation. Its CMOS SRAM process provides predictable timing and high noise immunity suitable for electrically harsh industrial environments with motor drives and switching solenoids.
Recommended
Bus Interface Bridging
Boards that bridge between incompatible bus standards - VMEbus to PCI, PMC to PCI, or ISA to PCMCIA - use FLEX 6000 FPGAs like the EPF6024AQI208-4 to implement bus state machines, address decoders, and interrupt controllers. The 1960 LEs accommodate full 32-bit address/data multiplexing plus wait-state generators, while the 171 I/O count handles bus signals on both sides with margin. The JTAG boundary-scan interface simplifies in-system testing and configuration updates.
Recommended
Replacement of Discrete 74-Series TTL/MSI
Long-lifecycle systems originally built around discrete 74LS/74F/74AS TTL MSI logic (counters, registers, decoders, multiplexers) can consolidate multiple chips into a single EPF6024AQI208-4. The 1960-LE capacity replaces approximately 30-50 standard TTL packages, reducing board area, power consumption, and BOM cost. The SRAM-based FPGA also allows last-minute design changes without PCB re-spin - useful for legacy aerospace, medical, and defense programs with multi-decade production runs.

Key Differentiators
- Highest logic density in FLEX 6000 family at PQFP-208 (vs EPF6016QI208-3)

- Standard Altera FLEX 6000 die with broad ecosystem support (vs Other vendors' FPGA solutions)
Design Notes
SRAM-based FPGAs are volatile: the EPF6024AQI208-4 loses its configuration when power is removed, so an external configuration memory is mandatory. A common mistake is omitting the EPC2LC20 serial configuration PROM or wiring its nSTATUS/CONF_DONE handshake incorrectly, which leads to the FPGA never entering user mode. Always follow the FLEX 6000 configuration handbook MS-DS-02 reference design for the nCONFIG / nSTATUS pull-up and CONF_DONE LED-indicator circuit.
PQFP-208 with 0.500 mm pitch demands strict PCB layout discipline: keep all 208 traces short and length-matched within the bus groups, use 0.200 mm wide traces with 0.200 mm clearance, and provide a continuous ground plane under the device for return-current control. Decoupling: place 0.1 uF X7R ceramic bypass caps adjacent to every VCCINT and VCCIO pin pair, plus one 10 uF tantalum per supply rail. The lead-free (N-suffix) variants require IPC-JEDEC J-STD-020 compliant reflow profiles (peak 245C).
Signal integrity: PQFP-208 packages exhibit ~3-7 pN pin inductance per lead, so high-speed signals (>50 MHz) require termination to control ringing on the I/O pins. Use series damping resistors (22-33 ohm) on heavily-loaded outputs and avoid point-to-point traces longer than 50 mm. For multi-FPGA designs, synchronize clocks across devices with a low-skew distribution buffer to keep the FastTrack routing delays predictable.
Compliance Information
EPF6024AQI208-4 is a legacy PQFP-208 part that pre-dates RoHS requirements. Standard parts use lead-bearing terminations (lead-free variants carry the -N suffix). AEC-Q100 is not applicable to FPGAs in this family. No halogen-free or conflict-mineral certification was published.
