EPF6024ATC144-3S Overview
A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor whose logic fabric, routing, and I/O blocks are defined by a configuration bitstream loaded after manufacturing. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs), and the FLEX 6000 family specifically targets low-cost, high-volume glue-logic, bus-interface, and state-machine replacement applications where a complex CPLD or a full ASIC would be overkill.
Key features of the EPF6024ATC144-3S include 196 Logic Array Blocks (LABs), 117 usable I/O pins, embedded SRAM configuration memory, in-system programmability via the JTAG-compliant ByteBlaster or BitBlaster interface, and four dedicated clock input pins. The 'ATC' speed grade in the device suffix indicates the 142.86 MHz Fmax performance bin, while the trailing 'S' in the part number denotes a specific commercial/extended temperature variant.
Typical applications include 33 MHz/66 MHz PCI bus interface bridges, glue-logic integration for legacy microprocessors, asynchronous-transfer-mode (ATM) cell processing, video/imaging pipe-line control logic, and telecommunications channelizers. Because FLEX 6000 devices are SRAM-based, they must be configured at every power-up from a serial or parallel PROM, which is a key design consideration for any mission-critical boot sequence.
When designing with the EPF6024ATC144-3S, ensure the configuration memory is sourced from a compatible EPC1 or EPC2 configuration PROM (or a microcontroller bitstream) and that all unused I/O pins are left floating or tri-stated. The 144-pin TQFP footprint has a generous 1.0 mm pitch and exposed die-pad-like thermal path, simplifying PCB layout versus fine-pitch BGA alternatives.

Typical Applications
EPF6024ATC144-3S is suitable for 7 applications: PCI Bus Bridge / Interface Logic, Glue-Logic Integration for Legacy Microprocessors, ATM / Telecom Channelizer, Video / Imaging Pipe-Line Control Logic, Industrial State-Machine Replacement, Legacy Board Repair / EOL Maintenance, Education / FPGA Training Platforms.
PCI Bus Bridge / Interface Logic
The EPF6024ATC144-3S is well matched to PCI 33 MHz/66 MHz bus bridge designs because its 142.86 MHz internal Fmax comfortably exceeds the 66 MHz PCI clock and its 117 user I/Os easily absorb the full 49-pin PCI bus plus parity, interrupt, and side-band signals. Engineers typically instantiate target/initiator state machines, address/data multiplexers, and configuration-space registers in the 1,960 logic elements. Compared to a discrete TTL/CPLD solution, the FLEX 6000 reduces board area, integrates bus-master arbitration, and supports in-system JTAG debugging that accelerates bring-up.
Recommended
Glue-Logic Integration for Legacy Microprocessors
The EPF6024ATC144-3S serves as a unified glue-logic hub replacing 5-15 discrete 74-series TTL/MSI chips when interfacing legacy microprocessors to modern memories and peripherals. Its 196 LABs and 117 I/Os fit chip-select decoders, wait-state generators, bus multiplexers, and interrupt arbiters within a single footprint. The 3.3 V VCCINT allows direct interface to 3.3 V MCUs without level translation; the SRAM-based fabric supports design pivots late in the cycle via JTAG reconfiguration without board rework.
Recommended
ATM / Telecom Channelizer
The EPF6024ATC144-3S was a workhorse for ATM cell delineation, AAL segmentation-and-reassembly, and T1/E1 channelizer implementations in late-1990s telecom equipment. Its 142.86 MHz Fmax sustains the 155 Mbps cell rate with comfortable margin, while the 117 I/Os support UTOPIA-style parallel PHY interfaces and HDLC framer connections. Designers mapped cell-header error-correction and SAR FIFOs into the embedded LE registers, using the JTAG port for in-system protocol debugging.
Recommended
Video / Imaging Pipe-Line Control Logic
The EPF6024ATC144-3S is used to build timing controllers, sync separators, and pixel-format converters for legacy digital video equipment such as CCTV DVRs and broadcast format converters. Its 117 I/Os handle 18-24 bit parallel RGB buses plus HSYNC/VSYNC/DE and ancillary data, and the 142.86 MHz Fmax easily meets 480p/576p pixel clock requirements. The flexible LAB structure lets designers implement FIR filters for chroma interpolation entirely in fabric, eliminating a dedicated chroma IC.
Recommended
Industrial State-Machine Replacement
The EPF6024ATC144-3S replaces multiple discrete state machines in industrial controllers, allowing new logic revisions to be downloaded via JTAG in the field rather than requiring chip swaps. With 196 LABs, designers can implement 4-8 independent Mealy/Moore state machines in parallel, each controlling a sub-system such as a motor driver, sensor multiplexer, or HMI keypad scanner. The 3.3 V core is tolerant of 5 V inputs on most I/O banks (with proper configuration), preserving compatibility with legacy industrial sensors.
Recommended
Legacy Board Repair / EOL Maintenance
The EPF6024ATC144-3S is sourced today primarily for MRO (maintenance, repair, overhaul) of legacy boards whose original FLEX 6000 device has failed or been damaged. The TQFP-144 footprint and bitstream-format compatibility mean a direct swap restores functionality without board rework or firmware changes. For 10-year+ lifecycle programs in aerospace, defense, or industrial automation, sourcing this part from authorized brokers is the most cost-effective repair path versus redesign.
Recommended
Education / FPGA Training Platforms
Universities and FPGA training labs used the EPF6024ATC144-3S as a teaching vehicle for introductory VHDL and Verilog design, since the device was supported by both Quartus MAX+PLUS II and early Quartus Prime flows. The 1,960 LEs provide enough headroom for student projects (UART cores, simple CPUs, VGA controllers) without overwhelming beginners. Today, surplus boards using this device are popular teaching aids in digital-logic curricula that emphasize SRAM-based configuration and JTAG boundary-scan.

Key Differentiators

- Pin-compatible RoHS-compliant drop-in replacement (vs EPF6024ATC144-3N)
- Higher speed grade over cost-optimized siblings (vs EPF6024ATC144-2N / EPF6024ATC144-1N)
Design Notes
The EPF6024ATC144-3S draws its VCCINT core supply at 3.3 V from multiple package pins (5, 28, 71, 100, 132). Decouple each VCCINT pin with a 0.1 µF X7R ceramic placed within 5 mm of the pin, and add a single 10 µF bulk tantalum or polymer capacitor near the chip. VCCIO1-VCCIO4 banks can be powered independently from 2.5 V or 3.3 V depending on the I/O standard chosen in the Quartus MAX+PLUS II design; add a 0.1 µF + 10 µF pair on each bank to suppress simultaneous-switching noise.
Because the EPF6024ATC144-3S is SRAM-based, it loses its configuration on every power-down. Always include a compatible configuration PROM (EPC1, EPC2, EPC4, EPC8, or EPC16) on the board, or the FPGA will boot into an undefined state with all I/Os tri-stated. A common bring-up failure is leaving MSEL[1:0] floating - tie them through a 10 kΩ resistor to either VCC or GND to select the correct configuration mode (PS or AS).
Route JTAG signals TCK, TMS, TDI, TDO on the top layer with 50 Ω controlled impedance and keep them isolated from clock and switching I/O traces by at least 3W (3× trace width) to avoid configuration glitches. Place a 4.7 kΩ pull-up on nCONFIG and a 10 kΩ pull-up on nSTATUS per the FLEX 6000 datasheet to prevent spurious re-configuration events during power-ramp. The 144-pin TQFP has gull-wing leads on 1.0 mm pitch, so use a fine-pitch soldering iron or hot-air rework station for board repair.
The EPF6024ATC144-3S supports LVTTL, LVCMOS, PCI, and SSTL-3 I/O standards. For PCI 33 MHz/66 MHz applications, terminate the 66 MHz clock with a series 33 Ω resistor at the FPGA pin to dampen reflections. For LVDS inputs, ensure the 100 Ω differential termination is placed within 200 mils of the FPGA pin. Unused I/O pins default to tri-stated with weak pull-ups; explicitly disable them in the Quartus project to save ~0.5 mA per pin in the I CCINT supply.
Estimated: At Fmax = 142.86 MHz and full 117-I/O toggle, the EPF6024ATC144-3S dissipates approximately 0.6 W-0.8 W (input values: ICCINT ≈ 180 mA, ICCIO ≈ 30 mA at 3.3 V). The TQFP-144 package has a theta-JA of approximately 35 °C/W on a 4-layer PCB with 1 oz copper. Junction temperature rises 21-28 °C above ambient - no heatsink is required for typical commercial applications. For industrial-temperature designs, verify with the FLEX 6000 datasheet derating curves.
Compliance Information
