Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
EP1K10TC144-1 is suitable for 6 applications: Industrial Glue Logic and Bus Bridging, Legacy Peripheral Controller and IPC, Telecommunications Interface Bridging, Educational FPGA Prototyping and Lab Boards, Test and Measurement Front-End Logic, Automotive Infotainment Legacy Interface (Non-Safety).
Industrial Glue Logic and Bus Bridging
The EP1K10TC144-1 fits industrial glue-logic and bus-bridging tasks because its 576 logic elements and 72 LABs provide enough capacity for multi-protocol state machines, FIFO buffers, and address/data multiplexing between parallel buses (e.g., ISA-to-local bus, 8-bit MCU to 16-bit peripheral). The 92 user I/Os comfortably accommodate wide parallel interfaces such as 16-bit data + 12-bit address plus control. At 2.5 V core with 5 V-tolerant I/Os, the part bridges legacy 5 V peripherals to modern 3.3 V processors without external level shifters, while the embedded dual-port RAM (12,288 bits across 3 EABs) handles small data buffers directly without external SRAM. Commercial 0β70 Β°C rating suits factory-floor enclosures.
Recommended
Legacy Peripheral Controller and IPC
The EP1K10TC144-1 suits legacy peripheral controllers and industrial-PC (IPC) interface cards because the 144-LQFP package is easy to rework with through-hole-friendly TQFP footprints, ideal for field-replaceable cards in long-lifecycle IPC platforms. With 250 MHz internal capability on the -3 speed grade, the part can drive ISA, PCI-local, or VME bus interfaces with deterministic timing. The 12 Kbit embedded RAM is sufficient for command queues, status registers, and small packet buffers. Designers can implement custom DMA engines, interrupt controllers, or legacy I/O expansion (parallel port, RS-422, opto-isolated GPIO) in a single chip, eliminating multiple 74xx glue-logic devices on the board.
Recommended
Telecommunications Interface Bridging
Telecommunications line cards and access multiplexers frequently use the EP1K10TC144-1 to bridge between legacy TDM (T1/E1) framers and modern packet-based backplanes. The 92 user I/Os accommodate TDM data, clock, frame-sync, and backplane sidebands simultaneously. Its embedded dual-port RAM (12,288 bits across 3 EABs) provides elastic buffers for clock-domain crossing between TDM (1.544/2.048 MHz) and packet domains, while the JTAG-based in-system programmability simplifies field firmware updates via the central office's management plane. The 250 MHz internal fMAX supports parallel TDM aggregation at DS3/E3 rates without external PLDs.
Recommended
Educational FPGA Prototyping and Lab Boards
The EP1K10TC144-1 is widely deployed in university FPGA laboratories and Altera/Intel legacy development kits because the 144-LQFP package has generous pin spacing (0.5 mm pitch) that is hand-solderable for student labs, and the -1 speed grade is the most economical option. With 576 logic elements, students can implement complete RISC-V cores (such as the PicoRV32), UARTs, SPI controllers, VGA framebuffers, and modest CPU designs within the 10K-gate budget. The on-chip 12 Kbit dual-port RAM supports small register files and FIFO scratchpads, while the JTAG interface connects directly to the legacy Altera ByteBlaster or USB-Blaster download cables used in teaching environments.
Recommended
Test and Measurement Front-End Logic
Test-and-measurement instruments frequently use the EP1K10TC144-1 as front-end pattern generation, trigger sequencing, and timing logic because its deterministic LE-based architecture delivers repeatable timing under all temperature conditions. The 92 user I/Os can drive parallel DACs, address multiplexers, and trigger comparators simultaneously, while the embedded dual-port RAM stores waveform patterns or capture buffers. The 3.3 V LVTTL outputs (5 V tolerant on inputs) interface directly to legacy bench-instrument buses. JTAG-based in-system programming lets manufacturers update instrument firmware in the field without opening the enclosure, which is critical for installed-base test equipment.
Recommended
Automotive Infotainment Legacy Interface (Non-Safety)
Although the EP1K10TC144-1 is not AEC-Q100 qualified, it is sometimes specified in non-safety automotive infotainment head units where a robust 0β70 Β°C commercial-grade FPGA provides display-timing generation, button-debouncing, and CAN-to-LIN bridging for entry-level head units. Its 92 user I/Os accommodate LCD timing signals, key-scan matrices, and rotary-encoder inputs simultaneously. The 12 Kbit embedded dual-port RAM buffers display frames and audio samples, while the 2.5 V core plus 3.3 V I/O (5 V tolerant) interfaces directly to legacy automotive back-panel connectors. Designers should note that ACEX-1K is now obsolete, so new automotive designs should target Cyclone-series parts.

Design Notes
Estimated: The EP1K10TC144-1 requires a 2.5 V Β±5% core supply on VCCINT pins and a 3.3 V I/O supply on VCCIO pins. Core current scales with toggle frequency and utilized LEs; typical ICCINT is 30β80 mA for a 50% utilization design at 100 MHz, while ICCIO can reach 100β200 mA with all 92 I/Os switching. Decouple each VCCINT pin with a 0.1 Β΅F X7R ceramic plus a bulk 10 Β΅F tantalum, and decouple each VCCIO pin with 0.1 Β΅F plus 4.7 Β΅F bulk to keep ground bounce below 200 mVpp during simultaneous switching.
Place all configuration components (EPC2 serial PROM, JTAG header, MSEL pull-up/pull-down resistors) within 50 mm of the EP1K10TC144-1 to keep the configuration clock DCLK trace short and matched. Route the four JTAG signals (TDI, TDO, TMS, TCK) as a bus with 50 Ξ© characteristic impedance and a 10 kΞ© pull-up on TCK and TMS. Provide a 100 nF + 10 Β΅F decoupling pair at each VCCIO bank region, with vias within 2 mm of each power pin. Avoid routing high-speed clock signals adjacent to the JTAG bus.
Do not assume the EP1K10TC144-1 is RoHS-compliant β the standard part uses a SnPb terminal finish; choose the EP1K10TC144-1N for RoHS designs. Configuration memory is volatile: the device MUST have a serial configuration PROM (EPC2 family) or JTAG loader at every power-up, or it will fail to wake up with random garbage in its LEs. Do not exceed the 2.5 V VCCINT absolute maximum (3.0 V) or the device will suffer permanent core-damage. MSEL pins must be hardwired correctly for the chosen mode β incorrect MSEL settings result in configuration errors that mimic bad firmware.
Compliance Information
EP1K10TC144-1 uses a tin-lead (SnPb) terminal finish and is NOT RoHS-compliant. For RoHS designs, select the lead-free variant EP1K10TC144-1N. The device is commercial grade (0β70 Β°C) and is not AEC-Q100 qualified; not suitable for automotive safety-critical applications.
