EP1K10TC144-1N Обзор

The Intel (formerly Altera) EP1K10TC144-1N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) featuring 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 144-pin TQFP (Thin Quad Flat Pack) package. The device integrates 92 user I/O pins with 5V tolerant I/O capability and is fabricated on a 0.18 µm CMOS process operating from a 2.5 V core supply.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high density of gate arrays with the design flexibility of programmable logic. FPGAs sit in the hierarchy: FPGA -> programmable logic -> ASIC alternative -> digital integrated circuit. ACEX-1K devices are low-cost, SRAM-based FPGAs targeting high-volume glue-logic, bus-interface, and DSP co-processing applications where mid-range logic density is required without the cost of higher-end FPGA families.

Key features of the EP1K10TC144-1N include a maximum internal operating frequency of 250 MHz, embedded array blocks (EABs) implementing dual-port RAM, ROM, or FIFO functions, and a MultiVolt I/O interface supporting 2.5 V and 3.3 V signalling. The device supports in-system programmability via configuration schemes including passive serial, passive parallel synchronous, and JTAG. Per-device power consumption is typically 0.5 mA quiescent current plus dynamic current dependent on toggle rate and logic utilization.

Architecturally the EP1K10TC144-1N combines Logic Array Blocks (LABs) and Embedded Array Blocks (EABs). LABs implement general-purpose combinational and sequential logic while each EAB provides 4 Kbits of RAM that can be configured for synchronous single-port or dual-port memory. Fine-grained look-up tables (LUTs) drive efficient state-machine and arithmetic implementations, and dedicated carry chains support high-speed adders.

Typical applications include industrial control interfaces, legacy bus-bridging glue logic, communication backplane controllers, low-cost DSP pre-processing, and educational/development platforms. The 144-pin TQFP footprint is well suited to through-hole-friendly prototyping PCBs while still allowing surface-mount assembly.

When designing with the EP1K10TC144-1N, verify the configuration mode (typically passive serial for ACEX-1K) and EPC configuration memory compatibility. Use the Quartus II design software (legacy) or Max+Plus II to capture schematics and verify timing closure at 250 MHz worst-case.

Типичное применение

EP1K10TC144-1N подходит для 6 применениеs: Industrial Bus-Bridging Glue Logic, Legacy Communication Backplane Controllers, Low-Cost DSP Co-Processor Front End, Educational and Development Platform Logic, Test and Measurement Instrumentation Front-End, Automotive Aftermarket Display Controllers.

🏭

Industrial Bus-Bridging Glue Logic

The EP1K10TC144-1N's 576 logic elements and 92 I/O pins make it ideal for bridging legacy parallel buses such as ISA, PC/104, and proprietary 16-/32-bit industrial interfaces. Its 250 MHz internal frequency easily handles 50-66 MHz bus cycles while the 3 EABs (12 Kbits) can implement small dual-port FIFOs for clock-domain crossing. ACEX-1K devices have been widely deployed in PLC backplanes, motor-drive controllers, and factory-automation I/O cards where MultiVolt I/O allows direct 3.3 V peripheral attachment.

🌐

Legacy Communication Backplane Controllers

The EP1K10TC144-1N's 92 I/O pins and 144-pin TQFP footprint are well suited to backplane controller designs implementing low-density protocol bridges (HDLC, UART aggregation, SPI/I2C fan-out). Designers leverage the 12,288-bit embedded RAM to buffer packets at line rate, and the 250 MHz fMAX accommodates 100+ Mbps serial bit-banged interfaces. The 2.5 V core plus MultiVolt I/O supports both 2.5 V and 3.3 V backplane rails commonly found in legacy telecom and datacom shelves.

🎧

Low-Cost DSP Co-Processor Front End

The EP1K10TC144-1N is used as a pre-processing stage ahead of dedicated DSPs in audio, motor-control, and instrumentation systems. The 576 logic elements implement FIR filter taps, decimators, and sample-rate converters while the 12 Kbit embedded RAM holds coefficient tables and delay lines. At 250 MHz fMAX the device can sustain 80 MHz sample rates in pipelined architectures, providing the necessary throughput for 16-bit audio processing in consumer and prosumer equipment.

Test and Measurement Instrumentation Front-End

The EP1K10TC144-1N's 250 MHz fMAX and 92 I/O make it a useful pattern-generator or logic-analyzer front-end in mid-range test equipment. Engineers use the 3 EABs to buffer captured waveforms and the LABs to implement trigger comparators, sequencers, and timing generators. The TQFP-144 package simplifies prototyping on through-hole-friendly instrumentation PCBs where BGA parts would require expensive reflow rework.

Automotive Aftermarket Display Controllers

Although the EP1K10TC144-1N is commercial-grade (0°C to +70°C), it has been widely deployed in aftermarket automotive products such as head-up displays, gauge clusters, and infotainment adapters where the host enclosure provides thermal management. The 92 I/O pins drive LCD panels directly through on-chip LVDS-style serializer macros, and the 12 Kbit embedded RAM buffers frame data. Designers target this part for cost-sensitive aftermarket tiers that cannot justify AEC-Q100 certified FPGAs.

What is the EP1K10TC144-1N FPGA and what family does it belong to?

The EP1K10TC144-1N is a 10,000-gate member of the Intel (formerly Altera) ACEX-1K family of SRAM-based Field Programmable Gate Arrays. According to the ACEX-1K datasheet, it integrates 576 logic elements, 3 Embedded Array Blocks providing 12,288 bits of RAM, and 92 user I/O pins in a 144-pin TQFP package. It is fabricated on a 0.18 µm CMOS process and operates from a 2.5 V core supply.

What is the operating voltage of the EP1K10TC144-1N?

The EP1K10TC144-1N operates from a 2.5 V core supply with MultiVolt I/O supporting both 2.5 V and 3.3 V signalling on the same die. According to the ACEX-1K datasheet, the device tolerates mixed-voltage buses, allowing direct interface to 3.3 V peripherals while keeping the core at 2.5 V for low power consumption.

What is the maximum operating frequency of the EP1K10TC144-1N?

The EP1K10TC144-1N speed grade -1 supports a maximum internal operating frequency of 250 MHz. According to the ACEX-1K datasheet, the -1 grade is the slowest in the family; the -2 grade is faster and the -3 grade is the fastest available, so designers targeting higher margins should consider -2 or -3 speed grades of the same EP1K10 die.

How much embedded memory does the EP1K10TC144-1N have?

The EP1K10TC144-1N contains 12,288 RAM bits distributed across 3 Embedded Array Blocks (EABs), with each EAB providing 4 Kbits of memory. According to the ACEX-1K datasheet, each EAB can be configured as single-port RAM, dual-port RAM, ROM, or FIFO, allowing designers to replace external memory devices on small bus-bridging designs.

What package does the EP1K10TC144-1N use?

The EP1K10TC144-1N is housed in a 144-pin TQFP (Thin Quad Flat Pack) package with 92 user I/O pins brought out to the perimeter. According to the ACEX-1K datasheet, the TQFP-144 footprint is shared with several ACEX-1K density points, which simplifies PCB reuse when migrating between EP1K10, EP1K30, and EP1K50 devices.

Is the EP1K10TC144-1N still in production?

No, the EP1K10TC144-1N is in obsolete lifecycle status as of 2026-09-07. According to Intel product discontinuation notices, the ACEX-1K family has been superseded by Cyclone-series FPGAs. The part is still available through authorized distributors carrying obsolete-stock inventory, but new designs should target Cyclone II, Cyclone III, or newer devices.

Where can I buy the EP1K10TC144-1N today?

As of 2026-09-07 the EP1K10TC144-1N is available from authorized distributors handling obsolete Intel FPGA stock including Heisener (60,276 pieces), DigiKey, Mouser, Arrow, and Octopart-listed brokers. Pricing is request-for-quote on most obsolete channels because unit prices fluctuate with remaining inventory rather than list price.

What is the lead time for the EP1K10TC144-1N?

Lead time for the EP1K10TC144-1N varies by distributor as of 2026-09-07. Heisener lists "Can Ship Immediately" with an estimated delivery of Apr 9 - Apr 14 for in-stock lots, while non-stocking brokers typically quote 4-8 weeks because they must source from upstream obsolete inventory.

EP1K10TC144-1N vs EP1K10TC144-1 - what is the difference?

The EP1K10TC144-1N and EP1K10TC144-1 are functionally identical ACEX-1K FPGAs with the same 10K gates, 92 I/O, and 144-pin TQFP package. According to Intel part-numbering convention, the suffix differs only in packaging qualification: the 'N' suffix typically indicates lead-free / RoHS-compliant lead finish, while the base part may use a SnPb finish. The pinout is the same and the parts are drop-in interchangeable.

What is the best drop-in replacement for the EP1K10TC144-1N?

The best drop-in replacement for the EP1K10TC144-1N is the EP1K10TC144-1 itself, which is the same die and package with a non-N suffix (lead-finish variant). For a speed upgrade with identical footprint, the EP1K10TC144-2N (speed grade -2) or EP1K10TC144-3N (speed grade -3) are pin-compatible in the same TQFP-144 package.

Where can I download the EP1K10TC144-1N datasheet PDF?

The official EP1K10TC144-1N datasheet is bundled in the ACEX-1K datasheet handbook published by Intel (formerly Altera).

The EP1K10TC144-1N pinout assigns the 92 user I/O pins to the perimeter of the 144-pin TQFP, with the remaining pins reserved for VCCINT (2.5 V core), VCCIO (I/O bank supply), GND, JTAG signals (TCK, TMS, TDI, TDO), and configuration pins (MSEL, nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0). The complete per-pin map is in the ACEX-1K datasheet handbook Pin-Out Tables section.

Can the EP1K10TC144-1N be replaced by a Cyclone-series FPGA?

The EP1K10TC144-1N cannot be a direct drop-in replacement on the same PCB because Cyclone devices use different packages, pinouts, and supply voltages. However, modern Cyclone II EP2C5 or Cyclone III EP3C5 in TQFP-144 packages offer 4-8x more logic and RAM at lower cost, requiring only a Quartus re-compile and a configuration PROM swap.

What design software supports the EP1K10TC144-1N?

The EP1K10TC144-1N is supported by Quartus II version 13.0 and earlier, plus the legacy Max+Plus II design environment. According to Intel legacy support notes, modern Quartus Prime does not support ACEX-1K, so engineers maintaining existing ACEX-1K designs must keep an older Quartus II install or migrate to a Cyclone-series replacement.

What are the key specifications of the EP1K10TC144-1N that engineers should know?

The EP1K10TC144-1N key specifications are: 10K typical gates, 576 logic elements, 3 EABs totaling 12,288 RAM bits, 92 user I/O, 144-pin TQFP package, 2.5 V core, MultiVolt 2.5/3.3 V I/O, 250 MHz maximum internal frequency, SRAM-based configuration requiring an external EPC configuration PROM, and obsolete lifecycle status as of 2026.

Руководство по выбору

Choose the EP1K10TC144-1N when maintaining an existing ACEX-1K design that requires the exact lead-free TQFP-144 footprint with 92 I/O and the -1 speed grade. For new designs, prefer the EP1K10TC144-1 (non-N suffix, SnPb lead finish) only if your assembly process requires tin-lead solder. Step down to EP1K10TC100-3N when you can accept 66 I/O and need the fastest -3 speed grade in a smaller footprint. Step up to EP1K10QC208-1N or EP1K10FC256-2N when you need more than 92 I/O while keeping the same 10K-gate logic capacity. For designs needing much higher density, consider EP1K100QC208-1N (10x more gates) or migrating to the Cyclone-series (Cyclone II EP2C5 or Cyclone III EP3C5) which offer lower cost and modern tool support, accepting that the PCB layout must be reworked.

Заметки по проектированию

Estimated: at typical 25% logic utilization toggling at 100 MHz, the EP1K10TC144-1N draws approximately 50-80 mA from VCCINT (2.5 V). Design a 2.5 V regulator with at least 200 mA headroom to handle worst-case fMAX activity. Decouple every VCCINT pin with a 0.1 µF X7R ceramic placed within 5 mm of the pin, plus a single 10 µF bulk tantalum or ceramic near the supply pins. MultiVolt I/O banks should each have their own 0.1 µF decoupling cap if multiple VCCIO rails are used.

The EP1K10TC144-1N is SRAM-based and loses configuration on power-down, so an external configuration PROM (EPC1, EPC2, or compatible) is mandatory. The most common configuration scheme is passive serial with an EPC2LC20 or EPC4QC100 PROM, which loads the bitstream on nCONFIG rising edge. For JTAG-only prototyping use the ByteBlasterMV cable connected to TDI/TMS/TCK/TDO. Always tie MSEL0/MSEL1 to the correct logic levels (typically 0/0 for passive serial) before power-up to select the configuration mode.

Estimated: do not confuse the EP1K10TC144-1N with the EP1K10TC144-3N when ordering - the speed grade -1 is the slowest in the family and may not meet 250 MHz timing in worst-case place-and-route. Verify the exact suffix (1, 2, 3 for speed; N for lead-free finish) before PCB assembly because ACEX-1K packages are not interchangeable with Cyclone-series FPGAs despite similar pin counts. Also avoid 5 V input signals directly on I/O pins unless the design confirms 5 V tolerant capability at the specific VCCIO level; MultiVolt I/O is not the same as 5 V tolerance.
