Typical Applications
EP1K30TC144-2 is suitable for 6 applications: Bridge and Glue Logic Replacement, Industrial Control Front-End Logic, Legacy ASIC Replacement for Low-Volume Production, Custom I/O Expansion for Microcontrollers/DSPs, Low-Volume Prototype and Educational Platform, Medical Device Interface and Signal Conditioning Logic.
Bridge and Glue Logic Replacement
The EP1K30TC144-2 is well-suited to replacing clusters of discrete 74-series TTL or CMOS glue logic on legacy boards, where its 1,728 logic cells and 24 Kbits of dual-port EAB SRAM let one device absorb address decoding, bus arbitration, register banks, and small FIFOs that previously required a dozen or more SSI/MSI parts. The 144-pin TQFP gives 102 user I/Os - enough to swallow wide address and data buses plus interrupt and control lines - while the 200 MHz -2 speed grade meets the timing budget of legacy 33 MHz-66 MHz peripheral interfaces. Designers migrate glue-logic boards to ACEX 1K to reduce PCB area, cut BOM cost, and gain the ability to iterate logic via in-system JTAG reprogramming instead of wire-wrap rework.
Recommended
Industrial Control Front-End Logic
In industrial PLC and instrumentation front-ends, the EP1K30TC144-2 is used to consolidate encoder counters, pulse-width modulation, and custom serial protocol handlers into a single reprogrammable part. Its 2.5 V core with 3.3 V-tolerant LVTTL/LVCMOS I/Os interfaces directly to industrial-grade ADCs, optoisolated digital inputs, and RS-485 transceivers, while the 0 to +70 °C commercial operating range matches the typical enclosure ambient of a control cabinet. The 200 MHz internal clock supports fast servo-loop timing and deterministic protocol decoding, and the 102 user I/Os handle many parallel sensor channels without external bus expanders. JTAG-based in-system programming lets the same hardware ship with multiple firmware personalities for different machine variants.
Recommended
Legacy ASIC Replacement for Low-Volume Production
When a legacy ASIC reaches end-of-life and the production volume does not justify a full mask re-spin, the EP1K30TC144-2 is a frequent substitute. With 30,000 system gates and 24 Kbits of EAB memory, it can emulate the gate-plus-memory content of many late-1990s/early-2000s ASICs, and its 144-pin TQFP footprint is compatible with the pin count of typical 144-pin PQFP ASIC packages. Designers use the Altera/Intel Quartus II toolchain (legacy version supporting ACEX 1K) to retarget the RTL, and the JTAG port enables field upgrades without board rework. The 2.5 V core maps cleanly to the 2.5 V I/O libraries common to ASIC libraries of that era.
Recommended
Custom I/O Expansion for Microcontrollers/DSPs
The EP1K30TC144-2 commonly expands the limited GPIO count of microcontrollers or DSPs by acting as a programmable peripheral, exposing custom interfaces (PWM generators, quadrature decoder, I2S, parallel camera) over a memory-mapped bus. With 102 user I/Os and LVCMOS-compatible I/O banks, the device can directly fan out to 7-segment displays, keypad matrices, LCD panels, and LED drivers without intermediate buffers. The 6 EABs (24 Kbits total) double as small FIFO buffers between the processor and high-speed data streams, smoothing DMA bursts. The 200 MHz internal clock allows 40 MHz parallel I/O rates when interfacing to mid-speed peripherals.
Recommended
Low-Volume Prototype and Educational Platform
The EP1K30TC144-2 sits at a friendly complexity point for university digital-logic courses and rapid prototypes: large enough to host a 16-bit CPU soft-core, small enough to fit a single semester lab. Its 30,000-gate capacity supports classic teaching examples such as UART controllers, simple RISC cores, VGA-timing generators, and state-machine demonstrators, while the 102 I/Os provide enough pins for student breadboard-style header arrays. The 2.5 V core voltage teaches important modern-power-rail lessons, and the JTAG-based programming flow exercises the same skills used in professional FPGA design.
Recommended
Medical Device Interface and Signal Conditioning Logic
In medical instrumentation front-ends (ultrasound beam-formers, patient monitor signal paths, lab analyzers), the EP1K30TC144-2 functions as a customizable logic layer between analog front-end ICs and the host processor. Its dual-port EABs (24 Kbits total) allow simultaneous read/write access from the host and the FPGA logic, which is ideal for sample-rate-conversion FIFOs and digital decimation filters. The 200 MHz clock budget supports decimation/interpolation at audio and low-IF sample rates, while the 144-pin TQFP gives enough I/Os for parallel ADC/DAC buses and trigger lines. Medical designs qualify the device under IEC 60601-1 and use the JTAG port for secure in-field firmware updates.

Design Notes
The EP1K30TC144-2 requires a clean 2.5 V core supply at 2.375 V - 2.625 V. Use a dedicated LDO (TPS7A4525 or equivalent) with at least 200 mA headroom, plus 10 µF + 0.1 µF decoupling placed within 5 mm of each VCCINT pin. VCCIO banks must be tied to 3.3 V for LVTTL/LVCMOS or 2.5 V for 2.5 V I/O standards; mixing VCCIO levels between banks is permitted but unbonded banks must still be powered. Estimated: with 1,728 cells at ~30% utilization, ICCINT ≈ 30-50 mA static and ICCINT ≈ 200-300 mA at 200 MHz toggle.
TQFP-144 has 0.5 mm pitch gull-wing leads - the PCB pad pattern must be per IPC-7351 nominal with 0.27 mm pad width and 1.6 mm pad length. Use microvia-in-pad if the design passes signal-integrity simulation, otherwise standard through-hole pads with tented vias. Route all 8 GND pins to a continuous ground pour directly under the package, and place 4-8 GND vias around the perimeter to stitch the top and bottom ground planes. JTAG TCK should be length-matched within ±25 mm across the four JTAG signals to avoid boundary-scan failures.
Three pitfalls are common on ACEX 1K designs: (1) Bitstream storage is volatile, so a configuration PROM (EPC2LC20 or EPC4) is mandatory - power-up without configuration causes the device to enter high-impedance with all I/Os tristated. (2) The MSEL[2:0] pins must be tied to VCCINT/GND to select configuration mode; floating MSEL pins is undefined and typically causes configuration failure. (3) I/O bank VCCIO must match the LVTTL/LVCMOS/PCI standard used in that bank - mixing 3.3 V and 2.5 V on the same bank damages the I/O cells over time. Always check the device errata document before final layout.
At 200 MHz internal clock, signals leaving the TQFP should be series-terminated at the source with 33 Ω resistors when the trace length exceeds one-quarter of the rise time (typically > 50 mm for 5 ns edges). Use a 4-layer PCB with continuous ground plane beneath the TQFP to control impedance to 50 Ω ±10%. Differential pairs (LVDS, when supported via external resistors) should be length-matched within ±0.5 mm. Keep JTAG traces away from clock edges and add a 4.7 kΩ pull-up on TCK to keep the JTAG state machine in a defined idle condition.
Compliance Information
ACEX 1K family predates strict RoHS enforcement - exact compliance depends on factory lot date code. The -2N suffix indicates lead-free finish for parts so marked. Reach, halogen, and conflict-minerals status not available in current data sources; consult CoC from distributor.
