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
EP1K10TC1443N is suitable for 6 applications: PCI Peripheral Controller, Glue Logic and Bus Bridge, Industrial Control and Instrumentation, Telecom Line Card and Channelized Interface, Test and Measurement Front-End, ASIC Replacement for Mid-Density Designs.
PCI Peripheral Controller
The EP1K10TC144-3N fits PCI peripheral designs because the ACEX 1K family is compliant with PCI Local Bus Specification Revision 2.2 at 5.0 V operation across all 92 user I/Os. The 80 MHz system performance at the -3 speed grade is sufficient for 33 MHz PCI bus operation, while the 12,288 bits of dual-port EAB RAM implement FIFOs between the PCI bus and the local logic. Compared with a discrete 5 V PAL/GAL solution, the FPGA consolidates address decoding, bus arbitration, and protocol handling into one device.
Recommended
Glue Logic and Bus Bridge
The EP1K10TC144-3N replaces discrete 74-series glue logic and protocol bridges (e.g., UART-to-PCI, I2C-to-parallel) with 576 logic elements and 92 user I/Os. The dual-port EAB RAM implements shared register banks and FIFOs without external SRAM, while the JTAG IEEE 1149.1 boundary-scan simplifies board-level test. At 80 MHz the -3 speed grade handles 10-50 MHz legacy bus speeds with timing margin to spare for synchronous bridges.
Recommended
Industrial Control and Instrumentation
Industrial PLCs and process controllers use the EP1K10TC144-3N for custom I/O expansion, encoder interface, and PWM generation. The 2.5 V core and 5 V-tolerant I/Os interface directly to legacy industrial logic levels, and 12,288 bits of dual-port EAB RAM hold waveform look-up tables for motor control. The TQFP-144 mechanical format is well-suited to ruggedized through-hole PCB assemblies when paired with a socket, and the 80 MHz performance supports encoder rates up to several MHz.
Recommended
Telecom Line Card and Channelized Interface
Telecom line cards leverage the EP1K10TC144-3N for T1/E1 framers, HDLC controllers, and channel aggregation logic. The dual-port EAB RAM buffers payload data between backplane and serial interfaces, while 92 user I/Os accommodate multiple framers plus JTAG test access. At 80 MHz the design meets the 1.544/2.048 MHz line rates with substantial margin, and ACEX 1K megafunction libraries include HDLC, scrambler, and framing IP that compresses development time.
Recommended
Test and Measurement Front-End
Custom protocol analyzers and logic analyzer front-ends benefit from the EP1K10TC144-3N's 576 logic elements, 92 user I/Os, and JTAG boundary-scan support for in-system test. Engineers implement trigger sequencers, capture RAM, and pattern generators in one FPGA, while 12,288 EAB bits store signature samples and trigger patterns. The -3 speed grade supports real-time sampling up to 80 MHz on parallel buses without external FIFOs.
Recommended
ASIC Replacement for Mid-Density Designs
The EP1K10TC144-3N replaces mid-density gate-array ASICs when NRE cost or schedule cannot justify a mask-programmed device. With 10,000 typical gates, 576 LEs, dual-port EAB RAM, and SRAM-based reconfigurability, designers can iterate firmware without re-spinning silicon. The TQFP-144 footprint fits standard 1.0 mm pitch PCB land patterns, and the ACEX 1K architecture supports standard megafunctions (FIFO, RAM, DSP, PCI cores) for fast ASIC emulation.

Key Differentiators
- Fastest -3 speed grade in the TQFP-144 ACEX 1K family (vs EP1K10TC144-2N)
- Industrial temperature range with 'N' suffix (vs EP1K10TC144-3 (no N suffix))
- Same package, same pinout as the broader ACEX 1K family (vs EP1K100QC208-3N (100K gates))
Design Notes
The EP1K10TC144-3N requires two supply rails: VCCINT = 2.5 V for the core and VCCIO = 3.3 V or 5 V for the user I/Os (PCI-compliant at 5 V). Power sequencing should bring up VCCINT before or simultaneously with VCCIO to prevent bus contention; add a 100 uF bulk capacitor and 0.1 uF decoupling per VCCINT/VCCIO pin pair. Estimated: a fully utilized EP1K10 with 80 MHz toggle draws approximately 200-400 mA on VCCINT (per ACEX 1K datasheet power calculator). Decoupling must keep the 2.5 V ripple under 50 mV.
Place the EP1K10TC144-3N with matched-length clocks to within 1 cm, and route configuration and JTAG signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0, TDI, TMS, TCK, TDO) with short, guarded traces. The dual-port EAB RAM benefits from localized routing: keep EAB-related signals within one LAB neighborhood. The TQFP-144 has a 0.5 mm lead pitch; use 0.15 mm/0.20 mm trace/space rules and at least 8 mil via-in-pad or tented vias for thermal relief.
The EP1K10TC144-3N uses SRAM-based configuration, so a configuration PROM (EPC2, EPC4, or compatible serial flash) is mandatory for non-volatile boot. Without it, the FPGA loses configuration on power-down. The 'N' suffix denotes industrial temperature range; omitting it (e.g., EP1K10TC144-3) yields the commercial-temp variant and may fail in industrial environments. Estimated: commercial temp is 0C to +70C while industrial is -40C to +85C for the -3N.
Compliance Information
ACEX 1K family predates wide RoHS adoption; lead-free/RoHS status for the EP1K10TC144-3N suffix is not documented in the verified web data. Mark as 'unknown' until confirmed from the original Altera/Intel PCN. AEC-Q100 is not applicable for industrial FPGAs.
