Typical Applications
EP1K10TI100-2N is suitable for 6 applications: Industrial Control Glue Logic, Communications Protocol Bridge, Low-Volume ASIC Replacement, Factory Automation Controller, Medical Instrumentation Front-End, Wireless Baseband Glue Logic.
Industrial Control Glue Logic
The EP1K10TI100-2N fits industrial control glue-logic boards thanks to its industrial temperature grade (-40C to +85C), 576 logic elements, and 66 user I/Os that easily accommodate parallel sensor multiplexing and discrete I/O expansion. Industrial PLC backplanes and motor-control auxiliary boards typically need a handful of registers, multiplexers, and protocol bridges that map directly onto 10K-gate ACEX-1K logic capacity. Industrial temp grading ensures operation across factory-floor temperature swings without thermal-induced timing failure. The 100-TQFP package simplifies PCB layout on standard 4-layer FR-4 boards used in industrial equipment. Engineers can implement custom state machines, watchdog timers, and encoder interfaces without paying for a higher-density FPGA.
Recommended
Communications Protocol Bridge
The EP1K10TI100-2N's 200 MHz internal performance, 12,288 bits of embedded dual-port RAM, and JTAG-based configuration make it well-suited as a protocol-bridge chip between UART, SPI, I2C, and custom LVDS interfaces on communications line cards. Telecom and networking equipment often needs to bridge legacy serial buses to newer packet interfaces, and the ACEX-1K's 4-input LUTs plus carry chain can implement small PHY-side state machines cleanly. Industrial temp grade supports outdoor cabinet deployments. The 66 user I/Os accommodate multiple parallel bus interfaces simultaneously, and the dual-port EAB RAM allows packet buffer staging without external SRAM. Modern migration targets would be Cyclone IV or Lattice ECP5 family parts.
Recommended
Low-Volume ASIC Replacement
The EP1K10TI100-2N is a strong candidate for low-volume ASIC replacement in legacy and mature products where NRE costs of a custom ASIC cannot be justified. With 10K typical gates, the part can replace simple custom glue ASICs that integrate memory, glue logic, and basic peripherals into a single chip. Its embedded dual-port RAM (12 Kbits) handles small buffer and lookup-table requirements that previously required external memory. Industrial temperature grade supports harsh-environment deployments in industrial automation and instrumentation. Programmable via JTAG, it allows field upgrades and last-minute design changes that mask-programmed ASICs cannot. Modern migration target: Cyclone 10 LP 10CL006 series.
Recommended
Factory Automation Controller
The EP1K10TI100-2N's industrial operating range and ACEX-1K cost-optimized architecture make it well suited for factory-automation auxiliary controllers such as conveyor sequencers, encoder counters, and machine-tool status monitoring. Its 576 logic elements fit the small-to-medium state machines and timers needed to coordinate motor starters, solenoids, and indicator panels. The 100-TQFP gull-wing package provides robust solder-joint reliability for vibration-prone industrial environments, and the 2.5V core with multi-voltage I/O banks can interface directly to 3.3V sensors and 5V-tolerant legacy signals. Designers benefit from Altera Quartus II legacy support for rapid recompilation of proven designs.
Recommended
Medical Instrumentation Front-End
The EP1K10TI100-2N is used in medical instrumentation front-ends such as patient-monitoring signal-conditioning boards and laboratory analyzer I/O controllers, where 10K-gate logic capacity suffices for filter state machines and ADC/DAC sequencers. Industrial temperature grading helps in clinical and laboratory environments with HVAC variability, and the embedded dual-port RAM allows small FIFO buffering of digitized sensor streams. The 66 I/Os handle parallel ADC sample buses plus display and keypad interfaces on portable patient monitors. Note that new medical designs should consider modern FPGA families with IEC 61508 / IEC 62304 documentation support and longer lifecycle commitments than the obsolete ACEX-1K.
Recommended
Wireless Baseband Glue Logic
The EP1K10TI100-2N serves as glue logic on wireless baseband boards where it bridges DSP processors, RF front-end chips, and baseband converters via custom LVDS or CMOS parallel interfaces. The ACEX-1K's 200 MHz capability matches many baseband clock rates, and the 12 Kbits of embedded dual-port RAM provide small packet and frame buffers. Industrial temp grade supports outdoor small-cell and pico-cell deployments. Its 100-TQFP package offers easy rework during prototype bring-up, and JTAG configuration supports field firmware updates on deployed radios. Designers of new radios should consider Cyclone V or Cyclone 10 LP families for integrated transceivers and longer lifecycle support.

Key Differentiators
- Industrial temperature grading (-40C to +85C) with N-suffix lead-free finish (vs EP1K10TC100-2N)
- Balanced -2 speed grade for most designs (vs EP1K10TC100-3)
- Lead-free Pb-free assembly (N suffix) (vs EP1K10TI100-2)
- Drop-in compatibility with TC/TCN/TI 100-TQFP variants (vs EP1K10QC208-2N)
Design Notes
The EP1K10TI100-2N requires a stable 2.5V VCCINT supply and 2.5V or 3.3V VCCIO bank supplies for I/O. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5mm of the pin, plus a bulk 10 uF tantalum at the regulator output. Bank VCCIO voltages may differ between banks; mixing 3.3V peripherals on one bank and 2.5V peripherals on another is supported but requires careful signal-level analysis at the I/O boundary. Power sequencing is not required.
Although the EP1K10TI100-2N is a small FPGA, sustained high toggle rates on many I/Os can raise junction temperature above ambient. The 100-TQFP package has modest thermal dissipation; in enclosed industrial enclosures above 60C ambient, designers should compute junction temperature using I/O-toggle power plus core static current, and consider airflow or heatsink attachment. Industrial-temp (TI) variants are rated -40C to +85C junction; commercial (TC) variants are 0C to 70C.
Use a 4-layer PCB with continuous ground plane beneath the EP1K10TI100-2N to provide low-impedance return paths for high-speed signals. Route JTAG signals TCK, TMS, TDI, TDO with 4.7 kohm pull-ups on TMS and TDI; route the JTAG chain as a daisy chain with stubs less than 25mm. Decoupling capacitors should be placed on the same layer as the FPGA using short, wide vias; avoid routing signal traces between the capacitor and its associated power pin. Conf-Done and nStatus should have 4.7 kohm pull-ups to VCCIO configuration bank.
Common pitfalls include: (1) attempting to program with Quartus Prime (which dropped ACEX-1K support) instead of legacy Quartus II; (2) forgetting to set MSEL0/MSEL1 for the desired configuration mode (AS, PS, JTAG); (3) using commercial-temp TC parts in industrial environments without re-validation; (4) expecting Cyclone IV bitstream compatibility - ACEX-1K uses an older programming file format not compatible with Cyclone series; (5) designing with EAB RAM widths/depths beyond 4 Kbit per block without checking utilization; and (6) ignoring I/O bank voltage mixing rules - inputs on a 3.3V bank driven by a 2.5V source need a level shifter or proper VCCIO selection.
Compliance Information
The N suffix indicates Pb-free / lead-free assembly per Altera legacy nomenclature. Formal RoHS, REACH, halogen-free, and conflict-minerals certifications were not found in the verified data; recommend confirming with distributor or broker lot documentation for obsolete-date-code inventory.
