EPF6024ATC144-14 Overview

The Altera EPF6024ATC144-14 is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) housed in a 144-pin Thin Quad Flat Pack (TQFP) package. It integrates 24,000 typical gates (logic density), 1,960 logic elements (LEs) organized as 196 Logic Array Blocks (LABs), and 117 user I/O pins, making it a mid-density programmable logic solution for glue logic, bus interfacing, and state-machine-heavy designs in the late-1990s/early-2000s era.

A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that uses an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and programmable I/O cells to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy (PLD -> CPLD -> FPGA) and offer the highest logic density and richest feature set at the cost of higher static power consumption and configuration memory requirements. The FLEX 6000 family uses a look-up-table (LUT)-based LAB architecture with SRAM configuration memory, requiring an external configuration ROM on power-up.

Key features of the EPF6024ATC144-14 include: 1,960 LEs, 196 LABs, 117 user I/O pins, typical operating frequency up to 200 MHz at the -3 speed grade, and 5V-tolerant I/O on a 3.3V core supply. The -14 speed grade denotes the slowest commercial grade, targeting cost-sensitive industrial and consumer applications where clock rates below 100 MHz are acceptable. The 144-pin TQFP package is a plastic surface-mount form factor with 0.5 mm lead pitch and a 22 mm x 22 mm body, designed for standard SMT reflow assembly.

The FLEX 6000 architecture uses a four-input LUT-based logic element, a hierarchical interconnect with FastTrack continuous routing, and embedded memory. The 1960-LE capacity is sufficient for medium-complexity glue logic, peripheral bridges, custom bus controllers, and instrumentation front-ends, but is now considered low-density by modern standards.

Typical applications include industrial motor-control interfaces, telecommunications line cards, custom peripheral bridges in legacy embedded systems, test and measurement backplanes, and ASIC prototyping. The 117 I/O pins support wide parallel buses (16-bit or 18-bit) common in legacy parallel interfaces such as ISA, PC/104, and VME.

When designing with this device, note that the FLEX 6000 family is mature and Intel/Altera recommends the MAX II or Cyclone series for new designs; the EPF6024ATC144-14 remains useful for long-lifecycle products, EOL bridge buys, and existing board repairs. Configuration requires an EPC configuration device or microcontroller-based configuration mode.

Typical Applications

EPF6024ATC144-14 is suitable for 6 applications: Legacy Industrial Motor Control Interface, Telecommunications Line Card Glue Logic, Custom Peripheral Bridge for Embedded Systems, Test and Measurement Backplane Controller, ASIC Prototyping and Emulation Vehicle, Legacy Industrial Bus Concentrator.

🏭

Legacy Industrial Motor Control Interface

The EPF6024ATC144-14 is well suited for legacy industrial motor control and AC drive interfaces requiring deterministic glue logic between DSP controllers and power-stage gate drivers. Its 1,960 LEs and 117 user I/O support PWM generation, quadrature encoder decoding, and CAN/RS-485 bus bridging in a single device, while the 144-TQFP package survives the 0C to +70C industrial envelope with adequate margin. Designers use the FLEX 6000 LUT-based fabric to implement SVPWM modulators with dead-time insertion and Hall-sensor debouncing in 100+ LEs, then route the 117 I/O directly to optocoupler-isolated gate driver inputs.

🌐

Telecommunications Line Card Glue Logic

In telecom line cards (T1/E1, ISDN PRI, early VoIP gateways), the EPF6024ATC144-14 served as a multi-function glue-logic device bridging framers, DSPs, and TDM backplanes. The 117 user I/O accommodate 4-6 parallel HDB3/AMI-coded serial links plus HDLC controllers, while the 196 LABs implement time-slot switching matrices for 32-64 channel DS0 streams. The 3.3V core with 5V-tolerant inputs simplified mixed-voltage interfacing to legacy 5V framer ASICs. The -14 speed grade is acceptable for 2.048 MHz E1 line rates and 8 kHz frame synchronization.

🖥️

Custom Peripheral Bridge for Embedded Systems

The EPF6024ATC144-14 is used as a custom peripheral bridge in VME, PC/104, and CompactPCI embedded backplanes where an off-the-shelf bridge ASIC is unavailable. Its 117 I/O pins route 32-bit multiplexed address/data buses plus 8-16 interrupt, DMA, and chip-select signals, while the 1,960 LEs implement wait-state generators, byte-swapping engines, and bus-arbitration state machines. The 144-TQFP package is supported by standard 4-layer PCB stack-ups with 0.5 mm pitch escape routing. Configuration is loaded from a low-cost EPC1 or EPC2 serial ROM at power-up.

🔧

Test and Measurement Backplane Controller

In automated test equipment (ATE) and bench instrumentation, the EPF6024ATC144-14 implements custom backplane controllers, GPIB-to-parallel adapters, and trigger-routing matrices. The 196 LABs hold LUT-based pattern generators and error-counting comparators, while the 117 I/O support IEEE-488 (GPIB) handshaking, parallel JTAG scan chains, and front-panel switch/LED multiplexing. The -14 speed grade easily handles 10 MHz pattern-generator clocks. Designers value the FLEX 6000 SRAM-based reconfigurability for field firmware updates on deployed test systems.

🧩

ASIC Prototyping and Emulation Vehicle

The EPF6024ATC144-14 was widely used as an ASIC prototyping vehicle in the late 1990s and early 2000s for pre-silicon validation of mid-complexity ASICs (~24K gates). Engineers mapped synthesized ASIC netlists directly into the FLEX 6000 LUT fabric, using the 117 I/O to replicate the ASIC's external bus and the JTAG port for real-time debug. The -14 speed grade provides typical signal-propagation latency for functional verification rather than at-speed timing closure. Multiple EPF6024ATC144-14 devices can be cascaded via the FLEX 6000 dedicated chain-interconnect pins for larger designs.

🏭

Legacy Industrial Bus Concentrator

The EPF6024ATC144-14 served as a multi-protocol bus concentrator in factory automation hubs, aggregating Profibus, Modbus RTU, DeviceNet, and CANopen segments into a single uplink. The 117 I/O support up to 6 isolated serial ports (RS-485 / RS-422 / CAN), each implemented in 200-400 LEs for UART, HDLC framing, and CRC-16 generators. The 3.3V core with 5V-tolerant I/O simplified interfacing to 5V CAN transceivers and 24V isolated RS-485 PHYs common in 1990s industrial PLC backplanes.

The EPF6024ATC144-14 pinout is published in the Altera FLEX 6000 Device Family datasheet (dsf6000), which contains a 144-pin TQFP pinout table listing each pin's function (user I/O, dedicated input, VCCINT, VCCIO, GND, JTAG TCK/TMS/TDO/TDI, configuration pins). The pinout is shared across all speed grades (-3, -7, -10, -14) of the EPF6024ATC144 package variant. The pinout is also referenced in the Quartus II Device Pin-Out File (.pin).
What are the key specifications of EPF6024ATC144-14 that engineers should know?
The EPF6024ATC144-14 is a FLEX 6000 SRAM FPGA with 1,960 logic elements, 196 LABs, 117 user I/O, 144-pin TQFP package, 3.3V core supply, 5V-tolerant I/O, and a -14 (slowest) speed grade. Configuration requires an external EPC series configuration ROM. The device is non-RoHS and obsolete as of 2026. Operating temperature is 0C to +70C commercial. Maximum internal toggle rate for this speed grade is approximately 80 MHz for typical 16-bit counter designs.
Can the EPF6024ATC144-14 be replaced by a Cyclone or MAX II device?
Yes, but a board redesign is required. The Cyclone EP1C3T144 or MAX II EPM240T100 are common modern replacements, but they are NOT pin-compatible - the package differs and the I/O map must be re-routed. The EPF6024ATC144-14 has a unique 144-TQFP footprint; engineers transitioning to modern devices must re-place the IC and re-route the I/O in Quartus II. For true drop-in replacement in legacy 144-TQFP, only FLEX 6000 variants work.
Hey Google, what can replace the EPF6024ATC144-14?
Drop-in replacements for the EPF6024ATC144-14 are other FLEX 6000 family variants in the same 144-TQFP footprint: EPF6024ATC144-10 (faster, 10 ns grade), EPF6024ATC144-13 (closest speed match, 13 ns grade), and EPF6016ATC144-3 (lower density, 1,320 LEs, 35% less logic). All share identical pin assignments. According to the FLEX 6000 datasheet, the EPF6024ATC144 family is the only Altera/Intel FPGA family in this exact 144-TQFP footprint with this logic density.
What is the best Intel equivalent for the EPF6024ATC144-14?
The best Intel (formerly Altera) equivalent is the EPF6024ATC144-10 in the same FLEX 6000 family, same 144-TQFP package, and same 1,960 LE density but with a faster speed grade. It is the most parametrically similar part per the Altera FLEX 6000 datasheet (dsf6000). The EPF6024ATC144-13 is another close Intel equivalent when -14 grade timing margins are required. Both are fully pin-to-pin compatible with no PCB changes needed.

Selection Guide

Choose the EPF6024ATC144-14 when designing a new FLEX 6000 product targeting clock rates below 80 MHz where cost optimization outweighs performance. The -14 grade is the slowest commercial speed bin, typically 15-25% cheaper than the -10 grade at qty 1000+. Choose EPF6024ATC144-10 if your design requires >100 MHz operation, EPF6024ATC144-13 if you need close to -14 timing margins with marginally better fMAX, or EPF6016ATC144-3 if your design fits within 1,320 LEs and you want to reduce unit cost. The 144-TQFP package is the largest TQFP variant in the FLEX 6000 family - for footprint-constrained designs under 81 I/O, use the 100-pin TQFP variant (EPF6024ATC100-10). For all new designs, Intel/Altera strongly recommends the Cyclone 10 LP family as a modern, RoHS-compliant, lower-power replacement (requires PCB redesign and Quartus Prime recompile).

Key Differentiators

  • Slowest speed grade (tpd ~14 ns) for cost-sensitive designs (vs EPF6024ATC144-10)
  • Pin-compatible with all FLEX 6000 144-TQFP family members (vs EPF6024AQI240-2)
  • Mid-density 24K gates with full 117 user I/O availability (vs EPF6016ATC144-3)

Design Notes

The EPF6024ATC144-14 requires two supply rails: VCCINT (3.3V core) and VCCIO (3.3V I/O, 5V-tolerant on inputs). Decouple each VCCINT pin with a 0.1uF X7R ceramic capacitor placed within 5 mm of the pin, and bulk-decouple each VCCIO pin with a 10uF tantalum + 0.1uF ceramic pair. Total ICCINT current for a fully utilized EPF6024 is approximately 50-100 mA static plus dynamic current proportional to toggle rate (estimated: 0.5 mA per MHz at 50% toggle activity across all 117 I/O). Plan power supply for at least 250 mA on the 3.3V rail.

The 144-pin TQFP package has a junction-to-ambient thermal resistance (theta_JA) of approximately 35 C/W in still air, requiring derating above 4W total power dissipation. Estimated: at 85C ambient with 1W internal dissipation, junction temperature rises to ~120C, exceeding the commercial 70C ambient rating if not de-rated. For industrial deployments above 60C ambient, attach a small clip-on heatsink or use a 4-layer PCB with a continuous ground pour under the TQFP thermal pad to reduce theta_JA to ~25 C/W.

The FLEX 6000 family uses volatile SRAM configuration memory - the EPF6024ATC144-14 must be reconfigured on every power-up from an external EPC1, EPC2, or EPC4 configuration ROM, or via microcontroller bit-banging in PS/PPS mode. Failure to pull nCONFIG high via a 10 kohm resistor and to monitor CONF_DONE results in unpredictable I/O behavior during power-up. Also note that the 5V-tolerant I/O is INPUT-only tolerance; do NOT drive outputs to 5V when VCCIO is 3.3V, as the output stage will be damaged.

The 144-pin TQFP with 0.5 mm lead pitch requires 0.25 mm-wide PCB pads with 1.5 mm pitch escape. Use a 4-layer PCB stack-up (signal/ground/power/signal) to maintain controlled impedance for clock traces. Place the EPC configuration ROM within 50 mm of the FLEX 6000 DATA[7:0] and DCLK pins to avoid configuration bit errors. JTAG chain (TDI/TMS/TCK/TDO) should be routed with 22 ohm series damping resistors if trace length exceeds 50 mm to suppress ringing at 10 MHz TCK.
