EPF6024ATC144-15 Overview
A field-programmable gate array (FPGA) is a reconfigurable integrated circuit that combines programmable logic blocks, programmable interconnect, and programmable I/O cells on a single semiconductor die. The FLEX 6000 family targets low-cost, high-volume gate-array replacement and rapid prototyping; within the broader semiconductor taxonomy it sits as a sub-class of programmable logic devices (PLDs) alongside CPLDs and structured ASICs.
Key features of the EPF6024ATC144-15 include a 3.3 V core supply, in-system programmability via SRAM configuration cells, built-in carry and cascade chains for high-speed arithmetic and wide-input functions, JTAG-compliant boundary-scan test support, and multi-voltage I/O banks. The -15 speed grade denotes a specific AC-timing bin within the FLEX 6000 family, where lower numeric values indicate faster timing.
Architecturally, the FLEX 6000 fabric is built from SRAM-based look-up tables (LUTs) that drive a four-input combinational function, with a dedicated register for sequential logic. The carry chain supports fast counters and adders, while cascade chains connect LEs 2 through 10 in each LAB and all LABs within the same half-row, enabling minimum-delay implementation of wide-input functions.
Typical applications for the EPF6024ATC144-15 include glue-logic integration in industrial control boards, telecommunications line-card controllers, bus-interface bridging (PCI, ISA, VME bridges), prototyping of gate-array designs, and replacement of discrete TTL/CMOS logic clusters where fast design changes are needed.
When designing with this device, confirm configuration mode (PS, PPS, AS, JTAG), supply decoupling (at least 0.1 µF plus bulk per rail), and unused-pin handling (drive to a defined logic level or use the Quartus/MAX+PLUS II "Enable All Pins as Inputs" option to suppress spurious toggles).

Typical Applications
EPF6024ATC144-15 is suitable for 6 applications: Industrial Glue-Logic Integration, Telecommunications Line-Card Controllers, PCI / ISA / VME Bus Bridge Implementation, Rapid Gate-Array Prototyping, Test & Measurement Instrumentation Front-End, Legacy TTL/CMOS Logic Replacement.
Industrial Glue-Logic Integration
The EPF6024ATC144-15 is well suited for industrial glue-logic boards where a moderate density of 1,960 logic elements and 117 user I/O pins can replace dozens of 74-series TTL packages with one programmable device. Its -15 speed grade provides ample timing margin for 33 MHz ISA-bus glue, address decoding, and interrupt controllers typical in PLC backplanes. The 3.3 V core supply and 144-LQFP surface-mount package enable compact single-sided PCB layouts. Engineers use the FLEX 6000 fast carry chain for counters and address decoders, while cascade chains implement wide-input equality comparators with minimum delay. Compared to discrete logic, this part reduces board area by 50-70% and allows in-system design changes via JTAG reconfiguration.
Recommended
Telecommunications Line-Card Controllers
In telecom line cards the EPF6024ATC144-15 implements HDB3/AMI encoding, framing, and timeslot management functions for T1/E1 and ISDN-PRI interfaces. The device's 1,960 LEs support 32-channel HDLC controllers, while the 117 user I/Os accommodate parallel bus connections to framer ICs and backplane transceivers. The 144-LQFP package fits standard line-card PCB outlines, and the SRAM-based configuration allows field upgrades of telecom protocols. With its carry chain, the part can implement CRC-32 calculations on T1/E1 frames at line rate. The JTAG boundary-scan support simplifies board-test access on densely populated line cards where traditional bed-of-nails testing is impractical.
Recommended
PCI / ISA / VME Bus Bridge Implementation
Engineers use the EPF6024ATC144-15 to implement protocol-conversion bridges between legacy PCI, ISA, and VME buses in industrial SBC and test-instrument applications. The 117 I/O pins provide ample headroom for the 32-bit PCI AD/C/BE lines plus side-band signals, while the 1,960 LEs hold a single 32-bit state machine plus bus-master arbitration logic. The -15 speed grade easily meets 33 MHz PCI timing with margin, and the 144-LQFP package is compatible with standard 4-layer PCI-mechanical card layouts. Configuration is typically done via the JTAG port in production test, allowing field reprogramming of bridge firmware without desoldering.
Recommended
Rapid Gate-Array Prototyping
The EPF6024ATC144-15 is frequently used as a fast-turnaround prototype before committing to a masked gate-array ASIC. With 24,000 usable gates and full SRAM reconfigurability, design teams can validate RTL behavior, clock-domain crossings, and I/O protocols within days rather than the months an ASIC iteration requires. The 144-LQFP package offers easy hand-soldering for engineering samples, while the 3.3 V supply simplifies prototype power design. The FLEX 6000 family is supported by MAX+PLUS II and Quartus Prime, allowing designs to be retargeted to MAX II CPLDs or Cyclone FPGAs once production volumes justify migration.
Recommended
Test & Measurement Instrumentation Front-End
In bench-top instruments such as logic analyzers, protocol testers, and data-acquisition front-ends, the EPF6024ATC144-15 provides pattern-generation, triggering, and channel-multiplexing logic. The 1,960 LEs can hold a 32-channel pattern sequencer with run-length encoding, while the 117 user I/Os accept multiple 8-bit or 16-bit parallel stimulus buses. The JTAG port enables automated test-program loading via boundary-scan. The 144-LQFP package keeps the front-end PCB compact, and the 3.3 V core allows direct interfacing to modern LVCMOS3.3 ADCs and DACs without level translation.
Recommended
Legacy TTL/CMOS Logic Replacement
Designers retrofitting obsolete industrial equipment use the EPF6024ATC144-15 to consolidate 20-40 SSI/MSI TTL packages (counters, multiplexers, decoders, latches) into a single reconfigurable device. The 117 user I/Os match the aggregate I/O of a typical mid-density logic cage, and the 144-LQFP footprint fits standard retrofit adapter boards. The -15 speed grade reproduces standard 74LS/74HC timing within margin. In-system SRAM configuration via JTAG means spare boards can be programmed with different replacement logic without stocking dozens of TTL part numbers.

Key Differentiators
- Largest density in the FLEX 6000 family in a 144-LQFP package (vs EPF6016ATC144-3)
- Pin-compatible drop-in across multiple speed grades (vs EPF6024ATC144-10)
- Highest pin-count option in the 144-LQFP FLEX 6000 line (vs EPF6010ATC144-3)
Design Notes
Estimated: EPF6024ATC144-15 core current draw is approximately 60-150 mA depending on toggle rate; at -15 speed grade worst-case VCCINT = 3.6 V. Decouple each VCCINT pin with a 0.1 µF ceramic plus a 10 µF bulk tantalum placed within 25 mm of the pin pair. VCCIO banks must each be decoupled separately because they can be independently driven. Add a ferrite bead on the analog 3.3 V input if switching noise from nearby DC-DC converters couples into the logic supply rail.
Place configuration EEPROM (EPC2 or compatible) within 50 mm of DCLK/DATA0/nCONFIG/nSTATUS/CONF_DONE to keep configuration traces short and well-matched. JTAG chain routing should follow IEEE 1149.1 recommendations - keep TCK trace clear of switching signals and add a 10 kΩ pull-up on TDI/TMS to keep the JTAG port in a benign state when unused. Unused I/O pins should be set as inputs with internal weak pull-up via Quartus/MAX+PLUS II device options to suppress spurious toggles.
Configuration bitstreams are speed-grade-specific: a programming file generated for EPF6024ATC144-15 will NOT configure the -10 or -3 grade correctly and may cause intermittent CONF_DONE failures. Always recompile in MAX+PLUS II or Quartus with the actual target speed grade selected. Verify MSEL0/MSEL1 strap values for the intended configuration mode (PS=00, PPS=01, AS=10, JTAG=11). The device is NOT 5 V-tolerant - interfacing to legacy 5 V logic requires external level shifters such as 74LVC245 or QuickSwitch devices.
Compliance Information
RoHS/REACH/lead-free compliance for EPF6024ATC144-15 is not explicitly stated in the verified distributor data; FLEX 6000 family predates widespread RoHS adoption so older lots may be non-compliant. AEC-Q100 is not applicable - FLEX 6000 is commercial-grade only.
