Typical Applications

EP1K30TI144-2 is suitable for 6 applications: Industrial Glue Logic & Bus Bridging, Legacy Telecom Interface Cards, Motor-Control Co-Processor, Educational & Prototyping Platforms, Parallel DSP Pre-Processing, Avionics & Defense Legacy Boards.

🏭

Industrial Glue Logic & Bus Bridging

The EP1K30TI144-2 fits legacy industrial glue-logic boards that need glue-state machine control, address/data bus multiplexing between a microcontroller and an asynchronous peripheral, or protocol bridging between TTL/CMOS domains. Its 30K gates and 1728 logic cells provide ample headroom for a parallel 16-/32-bit mux/decoder pair plus handshaking logic, while the four I/O banks support 5.0 V / 3.3 V / 2.5 V mixed-voltage bridging without external level shifters. Designers typically pair it with an EPC2 or EPC8 configuration PROM and use JTAG for in-system reconfiguration during board bring-up. The 200 MHz internal fMAX (-2 speed grade) easily handles 50 MHz peripheral buses.

Legacy Telecom Interface Cards

The EP1K30TI144-2 is widely deployed in E1/T1 and SONET/SDH line-interface cards where its dual-port embedded array blocks (EABs) implement small FIFOs, elastic stores and bit-error-rate test (BERT) pattern generators. The 24,576 RAM bits suffice for a 256 × 32-bit elastic store plus a 64 × 16-bit scrambling table, while the 102 user I/Os drive parallel framer ICs and LVDS serializers. Industrial temperature grade (-40 °C to +85 °C) and the legacy 2.5 V core supply match the central-office environment. Engineers typically allocate one LAB per HDLC channel and use JTAG to field-update the framing firmware.

Motor-Control Co-Processor

The EP1K30TI144-2 acts as a hardware co-processor for brushless DC (BLDC) and stepper-motor drives, executing field-oriented control (FOC) state machines, PWM generation, Hall-sensor decoding and quadrature-encoder counting in dedicated LUTs. Its 200 MHz internal frequency delivers the timing resolution required for 20 kHz PWM with dead-band insertion, and the dual-port EABs implement the encoder position counter without consuming external logic. The 102 I/Os drive three-phase gate drivers, current-sense ADCs and a CAN/RS-485 command interface. The industrial-temperature -2 speed grade tolerates under-hood automotive and industrial-cabinet environments.

🎓

Educational & Prototyping Platforms

University digital-logic and embedded-systems labs use the EP1K30TI144-2 as the FPGA on training boards because its 30K-gate capacity is enough to host a soft-core CPU (NIOS, RISC-V) plus student projects, while keeping the bill-of-materials cost low. The 144-TQFP footprint is breadboard-friendly with 0.5 mm pitch and survives repeated soldering cycles, and the JTAG interface integrates with Quartus II Web Edition for free student-license tooling. The 2.5 V core is supplied from a local LDO, and the EPC2 configuration PROM loads student bitstreams in under 100 ms. Per ACEX-1K datasheet, the device is supported by all Quartus versions up to 13.0sp1.

Parallel DSP Pre-Processing

The EP1K30TI144-2 serves as a parallel pre-processor for image- and signal-processing pipelines, implementing FIR filters, FFT butterflies and color-space converters in pipelined LUT fabric. Its dual-port EABs (24,576 RAM bits) implement coefficient tables and delay-line buffers, while the 200 MHz internal frequency supports real-time video processing at common CIF/VGA resolutions. Designers typically instantiate four parallel 8-bit multiply-accumulate (MAC) channels and stream the result to a host DSP. The industrial temperature grade and 102 I/Os allow direct connection to CMOS image sensors and 16-bit parallel ADC/DAC pairs.

What is the EP1K30TI144-2 FPGA?

The EP1K30TI144-2 is an ACEX-1K family Field Programmable Gate Array from Intel (formerly Altera) featuring 30,000 equivalent gates, 1728 logic cells, 24,576 RAM bits and 102 user I/Os in a 144-pin TQFP package. Per the manufacturer datasheet, it operates from a 2.5 V core supply, supports multiVolt 2.5/3.3/5.0 V I/O, and runs at up to 200 MHz internal frequency. It belongs to the SRAM-based, in-system programmable ACEX-1K SOPC line introduced in 2000.

What package does the EP1K30TI144-2 use?

The EP1K30TI144-2 ships in a 144-pin LQFP (also called TQFP) package measuring 22 mm × 22 mm with 0.5 mm lead pitch and gull-wing terminals. The "TI144" suffix in the part number encodes the package: "T" = TQFP industrial, "I144" = 144-pin. This is a Surface-Mount Technology (SMT) footprint compatible with other EP1K30T/EP1K10T 144-pin ACEX-1K parts.

What is the difference between EP1K30TI144-2 and EP1K30TC144-2?

The EP1K30TI144-2 carries the industrial temperature grade suffix "I" (-40 °C to +85 °C), while the EP1K30TC144-2 is the commercial temperature variant (0 °C to +70 °C). Both share the same 144-TQFP package, 30K gates, 102 I/O, and 2.5 V core, and are pin-compatible. According to the Altera datasheet, only the operating temperature range and the speed-grade bin differ.

Is the EP1K30TI144-2 still in production?

No, the EP1K30TI144-2 is obsolete. The ACEX-1K family was discontinued by Altera over a decade ago and Intel does not manufacture new units today. Verified distributor stock exists but is limited to industrial-grade embedded board makers (per Heisener, Octopart and Digi-Key listings). Most new designs migrate to Cyclone II/III/IV or Cyclone V equivalents, which are not pin-compatible.

Where can I buy the EP1K30TI144-2 online?

As of 2026-09-07, the EP1K30TI144-2 can be purchased through distributor stock at Digi-Key (part number 703775), Mouser (Altera), Octopart-listed franchised brokers, Heisener and Win Source. Prices vary by lot age and screening. Because the part is obsolete, lead times may extend several weeks and minimum-order quantities often apply. Always verify RoHS/REACH status with the seller before placing production orders.

What is the current price of the EP1K30TI144-2?

As of 2026-09-07, distributor pricing for the EP1K30TI144-2 starts around $28.50 at qty-1, scaling to roughly $13.85 at 1000-piece volumes (see the tiers[] table). Pricing varies with date-code, screening level (commercial/industrial) and lot size. Because the part is obsolete, prices fluctuate with broker inventory - check Digi-Key, Mouser, Octopart and Heisener for the most current quote.

EP1K30TI144-2 vs EP1K10TI144-2 - which is better for low-cost glue logic?

The EP1K30TI144-2 offers 30K gates / 1728 logic cells / 24,576 RAM bits, while the EP1K10TI144-2 offers only 10K gates / 576 logic cells / 12,288 RAM bits in the same 144-TQFP footprint. For pure low-cost glue logic with under 5K gates, the EP1K10 is more economical (≈60 % lower price). Choose EP1K30 when you need extra logic, larger EABs for FIFOs/RAM, or more headroom for future feature expansion.

Can I drop-in replace EP1K30TI144-2 with EP1K30TI144-2N?

Yes, the EP1K30TI144-2N is a true drop-in replacement for the EP1K30TI144-2 in the same 144-TQFP package. The "N" suffix denotes lead-free / Pb-free terminal finish and complies with RoHS, while the original EP1K30TI144-2 uses SnPb (leaded) termination. Both share identical die, pinout, speed grade, and 2.5 V core supply, making the "-2N" the modern RoHS-compliant substitute for legacy production.

What is the best drop-in replacement for the EP1K30TI144-2?

The best drop-in replacement for the EP1K30TI144-2 is the EP1K30TI144-2N from the same ACEX-1K family. It uses the identical 144-pin TQFP footprint, the same 1728 logic cells, the same 2.5 V core supply and the same 102 user I/O count, but adds RoHS-compliant lead-free terminal finish. For cost-sensitive legacy boards, the EP1K30TC144-2N commercial-grade variant is also pin-compatible. Both options avoid any PCB rework.

Where to download the EP1K30TI144-2 datasheet PDF?

The official Altera/Intel ACEX-1K datasheet (DS-ACEX1K-3.4) is hosted on Altera's legacy literature archive at https://www.altera.com/literature/ds/acex1k.pdf, and mirrored on distributor sites such as DigChip (digchip.net) and FPGAkey. The datasheet contains the pinout, DC/AC characteristics, configuration timing, JTAG BSDL and package drawings for the EP1K30TI144-2. Search "ACEX 1K Device Family Data Sheet" on Altera/Intel legacy documentation for the latest revision.

Where to find the EP1K30TI144-2 pinout?

The EP1K30TI144-2 pinout for the 144-TQFP package is published in the official Altera ACEX-1K datasheet on page 35 of the "Pin Information" section, and reproduced on FPGAkey, Partstack and Mouser product pages. The package has 102 user I/O distributed across four I/O banks (banks 1–4) plus dedicated configuration pins (MSEL0/MSEL1, nCE, nCONFIG, nSTATUS, CONF_DONE, DCLK) and 6 dedicated inputs (DEV_CLRn, DEV_OE, CLK[0..3] dedicated).

When should I choose EP1K30TI144-2 over EP1K50TI144-2?

Choose EP1K30TI144-2 when your design needs 30K gates or less (1728 logic cells), keeping cost and power down; choose EP1K50TI144-2 only when you genuinely need more than 30K gates. Both share the same 144-TQFP package, 102 I/Os and 2.5 V core. Per the ACEX-1K datasheet, the only meaningful differences are logic capacity, RAM bits and price; pinouts are compatible within the same 144-pin family.

Is the EP1K30TI144-2 suitable for new product designs in 2026?

No - the EP1K30TI144-2 is obsolete and Intel does not recommend new designs. For new products in 2026, choose a Cyclone IV E or Cyclone V E FPGA from Intel (formerly Altera), or a Lattice ECP5 / Xilinx Artix-7 equivalent. These modern parts offer lower core voltage (1.0–1.2 V), higher logic density, more RAM, and active lifecycle support. Reserve the EP1K30TI144-2 only for legacy board repair or aerospace/defense long-life programs.

What configuration PROM does the EP1K30TI144-2 require?

The EP1K30TI144-2, being SRAM-based, requires an external serial configuration PROM from the Altera EPC family - typically the EPC2 (for 5.0 V VCCIO) or EPC8 / EPC16 (for 3.3 V VCCIO). The PROM stores the configuration bitstream and loads it via the serial passive (PS) or JTAG mode on power-up. Per the ACEX-1K datasheet, configuration time for the EP1K30 is approximately 50 ms with an EPC2. JTAG in-system programming is supported via the TCK/TMS/TDI/TDO pins.

What cross-brand FPGA is comparable to the EP1K30TI144-2?

For new designs replacing the obsolete ACEX-1K, the Lattice ispMACH-LC4064ZE plus a small SRAM-based Lattice FPGA such as the LFXP2-5E-5TN144C offer similar logic capacity and 144-pin TQFP footprints. Xilinx Spartan-3AN (XC3S200AN-4TQG144C) is another cross-brand option. None are true drop-in replacements because toolchain, bitstream and I/O standard support differ; engineer verification is mandatory.

Selection Guide

Choose the EP1K30TI144-2 when you need a 30K-gate ACEX-1K FPGA in the legacy 144-TQFP industrial-temperature footprint for an existing 2.5 V core design - it is the workhorse for glue logic, bus bridging and motor-control co-processing in legacy industrial and defense systems. Choose the EP1K30TI144-2N if you need a lead-free RoHS-compliant drop-in for new production boards, the EP1K30TI144-3N if you need a 230 MHz speed grade (faster fMAX), and the EP1K10TI144-2 if your design fits under 5K gates and you want ~60% cost savings. Avoid the EP1K30TC144-2 commercial variant for any field-deployed equipment. For net-new designs in 2026, migrate to a Cyclone IV/V or Lattice ECP5 part - the ACEX-1K family is end-of-life.

Design Notes

The EP1K30TI144-2 requires four independent supply rails: VCCINT (2.5 V core), VCCIO1–VCCIO4 (per-bank I/O supply, supporting 2.5/3.3/5.0 V via multiVolt), plus VCCP and VCCA auxiliary pins. Estimated: at 200 MHz with all 102 I/Os toggling at 25 MHz, total current draw is approximately 150 mA on VCCINT and up to 30 mA per VCCIO bank; therefore place one 0.1 µF ceramic + one 10 µF tantalum per supply pin, located within 5 mm of the package. Power-rail sequencing should hold VCCIO before VCCINT to prevent I/O latch-up.

ACEX-1K is SRAM-based - configuration is lost on every power-down. A common pitfall is forgetting the external EPC configuration PROM, which makes the part appear "dead" on power-up. Use the EPC2LC20 for 5.0 V VCCIO or the EPC8QC100 for 3.3 V VCCIO. Per ACEX-1K datasheet, configuration time for the EP1K30 is approximately 50 ms with EPC2; pull CONF_DONE high through a 10 kΩ resistor to VCCIO for status indication. JTAG (IEEE 1149.1) supports in-system programming via TCK/TMS/TDI/TDO.

ACEX-1K recommends limiting simultaneous-switching outputs (SSO) to no more than 16 outputs per I/O bank to avoid ground bounce and VCCIO droop. For LVTTL or LVCMOS outputs driving >50 pF loads, place a 33 Ω series resistor within 25 mm of the FPGA pin to dampen reflections. Clock inputs (CLK[0..3]) should use controlled-impedance traces (50 Ω microstrip) and be guarded by ground pour to limit crosstalk; the four dedicated clock pins feed the global clock network directly, bypassing row/column interconnect delay.

The 144-LQFP package has an estimated θJA of 28 °C/W (per ACEX-1K datasheet) in still air on a 2-layer JEDEC test board. Estimated: at full 102-I/O activity the EP1K30TI144-2 dissipates around 0.7 W, leading to a junction-temperature rise of 19.6 °C above ambient - well within the 125 °C max junction. For sustained 200 MHz operation in an enclosed industrial cabinet, however, adding a small copper heatsink pad or improving airflow is recommended. Derate for ambient >50 °C.
