EPF6024ATC144-20 Overview
An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that combines the density of a gate array with the design flexibility of in-system programmability. Within the broader taxonomy, FPGAs sit alongside CPLDs under the Programmable Logic Device umbrella, which itself belongs to the digital integrated circuit family. The FLEX 6000 series uses a fine-grained architecture of 4-input look-up tables (LUTs) packaged into LABs that interconnect via FastTrack continuous routing channels, with carry and cascade chains for high-speed arithmetic and wide fan-in functions. FPGAs of this generation are typically configured from an external serial EPROM at power-up.
Key features of the EPF6024ATC144-20 include 24,000 typical gates, multiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V mixed-voltage operation, in-system programmability via the ByteBlaster or BitBlaster download cable, and JTAG boundary-scan compatibility (IEEE Std 1149.1). The device is fabricated on a 0.35 µm CMOS SRAM process and operates from a 3.3 V core supply. Pin-to-pin logic delay tPD is specified at 20 ns for this speed grade.
The device supports SRAM-based configuration loaded from a serial configuration EPROM such as the EPC2, allowing rapid prototyping and field upgrades. Each LAB contains 16 LEs, and each LE contains a 4-input LUT, a programmable register, carry and cascade logic, and an output buffer. MultiVolt I/O allows the device to interface directly with 5 V TTL, 3.3 V LVTTL, and 2.5 V HSTL/LVCMOS peripherals without external level shifters.
Typical applications for the EPF6024ATC144-20 include industrial control logic, glue-logic bridges between microcontrollers and peripherals, low-to-medium complexity state machines, custom bus interfaces (PCI, ISA, VME bridges), and legacy telecommunications equipment. Its moderate logic density and 117 I/Os make it ideal when several discrete TTL/CMOS parts can be replaced by a single reconfigurable device.
When designing with this part, note that the LQFP-144 footprint is footprint-compatible with other FLEX 6000 devices in the same package, allowing upward migration to higher-density family members (such as the EPF6016ATC144 or EPF6024AQC240 in different pin counts) without PCB rework on compatible packages. Designers should also budget for a configuration EPROM on the board and provide a JTAG header for in-system programming.

Typical Applications
EPF6024ATC144-20 is suitable for 6 applications: Industrial Glue-Logic Bridges, Legacy Telecom Equipment, Custom Bus Interfaces (PCI / ISA / VME Bridges), State-Machine and Sequencer Implementations, Test and Measurement Equipment, Aerospace and Defense Avionics Buses.
Industrial Glue-Logic Bridges
The EPF6024ATC144-20's 1960 logic elements and 117 user I/Os make it an ideal drop-in replacement for stacks of discrete 74-series TTL glue logic on legacy industrial control boards. With a 20 ns pin-to-pin delay, it can decode chip-select signals, arbitrate bus contention, and translate between 5 V peripherals and 3.3 V microcontroller buses using the on-chip MultiVolt I/O. Engineers commonly use it as a bus-monitor / address-decoder PLD replacement in PLC backplanes and motor-control inverters where deterministic combinational logic is required but the design volume does not justify a mask-programmed gate array.
Recommended
Legacy Telecom Equipment
Telecom infrastructure from the late 1990s and early 2000s frequently integrates the EPF6024ATC144-20 for TDM bus formatting, E1/T1 framer glue logic, and HDLC channel aggregation. Its 3.3 V core with 5 V-tolerant I/O simplifies interfaces to legacy line interface units, while 117 I/Os accommodate the many control and status signals typical of channel banks. For service and refurbishment of installed E1/T1 multiplexers and cross-connect systems, this part remains the closest drop-in for original Altera designs, with abundant third-party distributor stock available.
Recommended
Custom Bus Interfaces (PCI / ISA / VME Bridges)
The EPF6024ATC144-20 is widely used as a custom PCI-to-ISA or VMEbus bridge in test-and-measurement cards, data-acquisition boards, and embedded industrial PCs. Its 1960 LEs provide sufficient headroom for bus-state machines, address decoding, and interrupt steering, while 117 I/Os map cleanly to the address and data bus multiplexing required by 16-bit and 32-bit legacy backplanes. The 20 ns speed grade is well matched to 33 MHz PCI timing budgets, allowing designers to meet setup and hold requirements without manual delay tuning.
Recommended
State-Machine and Sequencer Implementations
With 196 LABs and fast carry / cascade chains, the EPF6024ATC144-20 efficiently implements deep finite-state machines and sequencer logic in industrial automation, instrumentation, and embedded-control applications. The 4-input LUT architecture allows efficient encoding of state machines up to ~16 states per LE, and the dedicated cascade chain supports wide-input AND/OR gating up to 33 inputs per row-half. Designers appreciate the deterministic 20 ns tPD for safety-critical sequences such as conveyor controllers, traffic-signal logic, and packaging-line sequencers.
Recommended
Test and Measurement Equipment
Bench-top instruments such as protocol analyzers, logic-analyzer pre-processors, and arbitrary waveform generators use the EPF6024ATC144-20 to implement pattern generators, custom trigger sequencers, and digital preprocessing pipelines. Its SRAM-based programmability allows field firmware updates via JTAG, useful for evolving test standards, while 117 I/Os accommodate the multi-channel parallel architectures common in logic-analyzer pods. The 20 ns speed grade maps well to 50 MHz pattern-generation clocks typical in production test equipment.
Recommended
Aerospace and Defense Avionics Buses
In legacy avionics LRUs (Line Replaceable Units), the EPF6024ATC144-20 implements MIL-STD-1553, ARINC 429, and custom discrete interfaces for flight-control and navigation subsystems. The device's commercial operating temperature grade is adequate for cockpit and cabin equipment, and its MultiVolt I/O interfaces directly to 5 V transceivers common in avionics. The 144-LQFP package suits ruggedized board layouts and is footprint-compatible with newer FLEX 6000 family members for cost-reduced refresh programs.

Key Differentiators
- Highest density in the FLEX 6000 family at the 144-LQFP package (vs EPF6016ATC144-3)
- Footprint-compatible migration across speed grades (vs EPF6024ATC144-2N)
- MultiVolt I/O eliminates external level shifters (vs EPF6010ATC144-3)
Design Notes
The EPF6024ATC144-20 requires a 3.3 V core supply (VCCINT) and one or more VCCIO rails per I/O bank to support 5.0 V / 3.3 V / 2.5 V MultiVolt operation. Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the package, plus a 10 µF bulk tantalum or ceramic capacitor near the regulator. Estimate: ICCINT active current is approximately 100-300 mA depending on toggle rate; check the FLEX 6000 datasheet Icc vs frequency graphs for your specific design utilization.
The 144-LQFP package has 0.5 mm lead pitch with exposed die-pad underneath; route all signals on inner layers to escape from the dense lead frame. Provide at least 4 PCB layers (signal, ground, power, signal) and flood the ground plane under the device for thermal dissipation and signal-integrity. Estimated: with all 117 I/Os switching at 25 MHz, expect ~1 W power dissipation; a 1 oz copper ground flood on top and bottom layers is the minimum thermal management.
Do not leave configuration EPROM nCONFIG or nSTATUS pins floating; pull nCONFIG high through a 10 kΩ resistor and monitor nSTATUS for configuration errors. A common mistake is omitting the JTAG header, which prevents in-system reprogramming - always include a 10-pin JTAG footprint (ByteBlaster MV compatible) on the PCB even if programming is done via the configuration EPROM. Also verify that all VCCIO banks are powered before VCCINT ramps, or the device may enter an undefined state.
The 144-LQFP plastic package has a θJA of approximately 35-40 °C/W (estimated, please verify with manufacturer thermal data). At 1 W dissipation in still air, junction temperature rises ~38 °C above ambient; for industrial-temperature designs near +70 °C ambient, ensure junction temperature stays below +125 °C by providing airflow or copper-flood cooling on the PCB top layer.
