EP1K10TC144-2N Visão geral

The Intel / Altera (formerly Altera Corporation) EP1K10TC144-2N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), delivering 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 144-pin TQFP (TC) package. Housed in a thin plastic quad flat pack measuring 22 mm × 22 mm × 1.4 mm with a 0.5 mm lead pitch, the device offers 92 user I/O pins and operates across a commercial 0 °C to +70 °C ambient range, with the speed grade -2 providing balanced performance and power for general-purpose logic integration.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed by the designer after manufacture. FPGAs sit at the top of the programmable logic hierarchy alongside CPLDs, occupying the intersection of ASIC-like density and software-driven design flexibility, and are widely used for glue logic, protocol bridging, and parallel DSP pipelines in industrial, communications, and test equipment.

Key features include an embedded array block (EAB) architecture with 12 embedded array blocks implementing dual-port RAM, ROM, or multiplier functions; 72 logic array blocks (LABs) arranged across the die; built-in JTAG boundary-scan test circuitry compliant with IEEE 1149.1; and support for multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL through dedicated I/O banks. Configuration is handled by a serial PROM, controller, or JTAG port, and the device operates from a single 2.5 V core supply with separate VCCIO rails for the I/O banks.

Typical applications include glue logic replacement on legacy PC/104 and VME boards, custom state-machine controllers in industrial automation equipment, low-density DSP pre/post-processing pipelines, and peripheral bridging (UART, I²C, SPI) in networking line cards. The 92 available I/O pins comfortably drive 8-bit or 16-bit parallel buses plus control signals, while the 12 Kbit embedded RAM supports small FIFO and lookup-table implementations without external memory.

Designers should pay particular attention to I/O bank voltage constraints: the EP1K10TC144-2N supports 2.5 V and 3.3 V on the same die, but mixing 5 V inputs requires external resistor dividers since the device has no 5 V-tolerant I/O. Quartus II design software (version 13.0 or earlier is the last release supporting ACEX-1K) is required for synthesis, place-and-route, and bitstream generation.

Aplicações típicas

EP1K10TC144-2N é adequado para 6 aplicaçãos: Industrial Glue Logic Replacement, Legacy Peripheral Bridging, Low-Density DSP Pre/Post-Processing, Custom State Machine Controllers, Telecom Line Card Glue Logic, Military & Aerospace Legacy Systems.

🏭

Industrial Glue Logic Replacement

The EP1K10TC144-2N replaces multiple 74-series TTL and CMOS glue-logic ICs on legacy industrial controllers with a single programmable device, reducing board area and assembly cost. Its 576 logic elements and 12,288 bits of embedded RAM comfortably accommodate typical state machines, address decoders, and timing generators used in PLC backplanes and motor-control boards. The 92 user I/O pins and four independently supplied VCCIO banks allow direct interfacing with 3.3 V and 2.5 V peripherals on the same PCB. Designers benefit from Quartus II synthesis, which preserves schematic capture from MAX+PLUS II designs, easing migration of proven legacy logic.

🌐

Legacy Peripheral Bridging

The EP1K10TC144-2N acts as a custom bridge between mismatched peripherals such as UART, I²C, SPI, and parallel buses in industrial PCs and test equipment. Each of the 12 embedded array blocks can be configured as dual-port RAM, ROM, or a small multiplier, supporting protocol-conversion FIFOs without external memory. The 2.5 V core and JTAG-based in-system programming enable field updates through the standard IEEE 1149.1 test access port. Designers targeting legacy PC/104 and VMEbus cards can leverage the abundant I/O count and IEEE 1149.1 boundary-scan testability to replace discrete bridge ASICs.

🔧

Low-Density DSP Pre/Post-Processing

The EP1K10TC144-2N implements small DSP functions such as digital filters, FFT pre-processors, and CRC engines alongside an external DSP or microcontroller in cost-sensitive test and measurement equipment. The 12 embedded array blocks each support dedicated multiplier modes, allowing 8-bit or 12-bit multiply-accumulate (MAC) operations at system clock rates up to 50 MHz. While the 10K-gate density is modest by modern standards, it provides just enough logic for sensor conditioning and signal conditioning pipelines in portable instrumentation. Designers pair the FPGA with an external ADC/DAC for complete analog signal chains.

🤖

Custom State Machine Controllers

The EP1K10TC144-2N excels as a custom state-machine controller for industrial automation, robotics, and material-handling equipment where deterministic sequencing and reliable I/O control are essential. The 576 logic elements and 72 logic array blocks map cleanly onto multi-state FSMs with parallel datapath logic, while 92 user I/O pins comfortably drive sensor inputs, actuator relays, and HMI display interfaces. JTAG boundary-scan testability simplifies board-level debugging and in-field firmware updates through the standard test access port. Designers value the predictable timing closure achievable with Quartus II timing analysis for safety-critical sequencing.

📡

Telecom Line Card Glue Logic

The EP1K10TC144-2N serves as glue logic on telecom line cards, replacing discrete bus-isolation, address-decoding, and interrupt-routing ICs around network processors and framer ASICs. The 12,288 bits of embedded RAM support small lookup tables used for header processing and routing decisions at line-card speeds. Four I/O banks allow direct 3.3 V interfacing to PHY chips and 2.5 V connections to the network processor, eliminating external level shifters. Designers benefit from low-cost legacy parts availability for long-lifecycle telecom infrastructure where reliability trumps performance.

✈️

Military & Aerospace Legacy Systems

The EP1K10TC144-2N continues to serve in long-lifecycle military, aerospace, and avionics platforms designed around ACEX-1K silicon in the late 1990s. While not radiation-hardened by modern standards, the commercial-grade device is qualified by many programs through up-screening processes and remains in service on legacy avionic displays, flight data recorders, and ground-test equipment. The 144-pin TQFP package is well-suited to high-vibration environments where fine-pitch BGAs are not desirable. Designers performing obsolescence management rely on factory-surplus and authorized-stock distributors for ongoing support.

What is the EP1K10TC144-2N?
The EP1K10TC144-2N is a member of the Altera ACEX-1K FPGA family, providing 10,000 typical gates, 576 logic elements, and 12,288 bits of embedded RAM. According to the Altera ACEX-1K datasheet, the device ships in a 144-pin TQFP (TC) package and uses speed grade -2. It is functionally a SRAM-based LUT FPGA with embedded array blocks for dual-port RAM and multipliers.
How many user I/O pins does the EP1K10TC144-2N have?
The EP1K10TC144-2N provides 92 user I/O pins, organized into four I/O banks that can each be supplied independently from 2.5 V or 3.3 V. The 144-pin TQFP package dedicates the remaining pins to VCCINT, VCCIO, GND, JTAG (TCK/TMS/TDO/TDI), and dedicated configuration inputs, leaving 92 general-purpose signals for user logic.
What is the difference between EP1K10TC144-2N and EP1K10TC144-1N?
The EP1K10TC144-2N carries speed grade -2 while the EP1K10TC144-1N carries speed grade -1. Speed grade -2 is the slower, lower-cost option, whereas -1 is the faster tier with shorter propagation delays. Both share the identical ACEX-1K die and 144-pin TQFP package, so they are pin-compatible and interchangeable when timing margins allow.
What software is required to program the EP1K10TC144-2N?
The EP1K10TC144-2N is supported by Altera (now Intel) Quartus II design software, with version 13.0 being the last release that retains ACEX-1K device support. Designers can also use the legacy MAX+PLUS II toolchain. Programming is performed through the JTAG port using a ByteBlasterMV or USB-Blaster download cable, with the resulting .sof or .pof bitstream loaded into SRAM cells at every power-up.
Where can I download the EP1K10TC144-2N datasheet PDF?
The Altera ACEX-1K datasheet covering the EP1K10TC144-2N can be downloaded as a PDF from third-party archives such as alldatasheet.com, where the document is approximately 1 Mbyte and 86 pages long. The original document is hosted in the Intel FPGA legacy documentation archive. Search for the MPN 'EP1K10TC144-2N' to retrieve the file.

Can the EP1C3T144C8N replace the EP1K10TC144-2N?
The EP1C3T144C8N (Cyclone family, 3,000 LEs) uses a different die and architecture than the EP1K10TC144-2N (ACEX-1K family, 576 LEs) but shares the 144-pin TQFP package and JTAG-based configuration. It cannot be considered a drop-in replacement because the bitstream, configuration file format, and IO bank voltages differ. Migration requires redesign with Quartus II device migration and a fresh synthesis run.
What I/O standards does EP1K10TC144-2N support?
The EP1K10TC144-2N supports LVTTL, LVCMOS, 3.3 V PCI, and SSTL I/O standards across its four user I/O banks. Each bank can be independently supplied with 2.5 V or 3.3 V VCCIO. The device has no 5 V-tolerant inputs; 5 V signals must be conditioned with external resistor dividers or level shifters before reaching the FPGA pins.

Guia de seleção

Choose the EP1K10TC144-2N when you need a 10K-gate ACEX-1K FPGA in a hand-solderable TQFP-144 package with speed grade -2 (balanced cost and performance). For designs requiring the fastest timing closure, choose the EP1K10TC144-1N (speed grade -1, identical footprint). For cost-optimized designs with relaxed timing, choose the EP1K10TC144-3N (speed grade -3). All four parts share the same TQFP-144 footprint and ACEX-1K die, so PCB layout reuse is straightforward. Migration to the modern Cyclone family (e.g., EP1C3T144C8N) requires a complete redesign because of differences in bitstream format, I/O bank architecture, and configuration scheme.

  • TQFP-144 is hand-solderable and field-rework friendly (vs EP1K10FC256-2N (FBGA-256))
  • Mature ACEX-1K architecture with extensive Quartus II legacy support (vs Cyclone EP1C3T144C8N)
  • On-site authentication and traceability through authorized distributors (vs Grey-market EP1K10TC144-2N lots)

Notas de projeto

The EP1K10TC144-2N requires a clean 2.5 V VCCINT rail for the core plus separate VCCIO supplies (2.5 V or 3.3 V) for each of the four I/O banks. Decouple each VCCINT and VCCIO pin with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the package pin, and add a bulk 10 µF tantalum capacitor near the FPGA supply entry point. Avoid routing high-frequency switching signals directly across the VCCINT plane to minimize core supply noise.

The TQFP-144 package has a theta_JA of approximately 35 °C/W in still air and around 25 °C/W with 400 cm² of 4-layer PCB copper. At typical 200 mA core current (500 mW dissipation), the junction temperature rises only 17 °C above ambient, so no heatsink is required. Estimated: assumed 4-layer JEDEC-standard test board and natural convection. Designers targeting sealed enclosures should add thermal vias beneath the package to the internal ground plane.

TQFP-144 with 0.5 mm pitch demands strict PCB layout discipline: trace width 0.15 mm minimum, via 0.3 mm drill, and a continuous ground plane beneath the package. Route all 92 user I/O signals on outer layers only and avoid stubs longer than 5 mm. Keep JTAG signals (TDI/TMS/TCK/TDO) bundled together and isolated from high-speed switching I/O. Solder paste stencil aperture should be 1:1 to land pad with 0.1 mm relief for fine-pitch 0.5 mm QFP packages.

Do not apply 5 V signals directly to the EP1K10TC144-2N user I/O pins because the device lacks 5 V-tolerant inputs; damage will result. Use external resistor dividers or level shifters (such as 74LVC245) for any 5 V source. Also ensure the nCONFIG and MSEL pins are correctly strapped for the desired configuration mode (e.g., MSEL=00 for passive serial). Configuration failures are most often caused by incorrect MSEL settings rather than silicon defects.

Series-terminate high-speed outputs (above 33 MHz) with a 33 Ω resistor placed within 5 mm of the FPGA driver pin to dampen reflections on 50 Ω controlled-impedance traces. For LVTTL outputs driving long capacitive loads, slew-rate adjustment via Quartus II settings reduces EMI. The four I/O banks must each have its VCCIO plane decoupled locally; mixing VCCIO voltages on a single bank is not supported and causes latch-up risk.
