EP1K50TC144-3N - ACEX-1K 50K Gates FPGA, 144-LQFP | Intel / Altera
MPN: EP1K50TC144-3N ✗ Akhir HidupEP1K50TC144-3N Ringkasan
An FPGA is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs) interconnected by a programmable routing matrix. FPGAs are positioned in the programmable logic hierarchy above CPLDs and below ASICs in terms of integration density, offering hardware-level parallelism for digital signal processing, glue logic, bus bridging, and protocol implementation. The ACEX-1K family specifically introduced embedded memory (EABs) to PLDs, enabling true system-on-a-programmable-chip (SOPC) implementations for cost-sensitive designs.
Key features include 166.67 MHz maximum internal operating frequency, 5.0 ns pin-to-pin logic delay, JTAG boundary-scan test support, multiVolt I/O supporting 2.5 V/3.3 V/5.0 V interfacing, and 102 user I/O pins arranged in four I/O banks. The architecture combines a fine-grained logic fabric with coarse-grained EAB memory blocks, allowing efficient implementation of megafunctions such as FIFOs, dual-port RAM, and DSP multipliers without external memory.
The 0.22 µm process technology delivers a balance of low static power and high performance. The four I/O banks support independent voltage reference (VREF) inputs, allowing mixed-voltage interfacing on a single die. Programmable interconnect delays and register-rich LABs optimize timing closure for state-machine and pipeline designs.
Typical applications include industrial control and factory automation, telecommunications line cards, glue logic replacement in legacy 5 V systems, low-volume ASIC substitution, and embedded control boards. The 144-LQFP plastic package simplifies prototyping and rework compared to BGA alternatives.
Designers should note that EP1K50TC144-3N is now classified Obsolete, so production runs require last-time-buy planning, firmware bitstream compatibility must be verified against Quartus II version 13.0 or earlier, and migration to Cyclone II / Cyclone III families is recommended for new designs.

Aplikasi Umum
EP1K50TC144-3N cocok untuk 6 aplikasis: Industrial Control & Factory Automation, Telecom Line Cards & Legacy Bus Bridging, Low-Volume ASIC Substitution, Glue Logic Replacement in 5 V Legacy Systems, Embedded Control Boards & Prototyping, Test & Measurement Instrumentation Front-End.
Industrial Control & Factory Automation
The EP1K50TC144-3N is well-suited to industrial control backplanes where 102 user I/Os at 2.5 V core / 5 V-tolerant multiVolt I/O bridge legacy 5 V PLC buses to 3.3 V microcontrollers without external level shifters. Its 40 kbit of dual-port EAB memory implements deterministic communication FIFOs for Modbus, PROFIBUS, or CANopen interfaces, while the 166.67 MHz fabric handles encoder feedback loops at microsecond rates. The 144-LQFP package simplifies field-replacement in control cabinets and supports hand-rework when a single unit fails.

Telecom Line Cards & Legacy Bus Bridging
Telecom line cards benefit from the EP1K50TC144-3N's 102 I/Os to bridge parallel H.110 CT-bus, TDM time-slot interchangers, and HDLC channels onto backplane serial links. The 360 LAB fabric at 166.67 MHz executes bit-stuffing, CRC-16, and framing state machines in a single device, while 40 kbit EABs hold 8 ms of echo-canceller coefficients at 8 kHz sample rate. multiVolt I/O interfaces directly to 5 V TDM framers. Designers should budget 1.2 W typical core power for thermal planning.

Low-Volume ASIC Substitution
For production runs of 500-10,000 units where ASIC NRE exceeds $300K, the EP1K50TC144-3N offers a fully programmable alternative. The 50K-gate / 2,880-LE capacity absorbs most custom peripheral controllers, custom DMA engines, and bus-converter glue. Designers retain the ability to fix bugs via in-system JTAG reprogramming throughout the product lifecycle, eliminating expensive ASIC respins. Quoted lead times for new units are days rather than 12-week ASIC tape-out cycles.

Glue Logic Replacement in 5 V Legacy Systems
The EP1K50TC144-3N's multiVolt I/O accepts 5 V inputs when VCCIO is set to 3.3 V, making it a one-chip replacement for banks of 74LS/74HC glue logic in legacy PC/104, VME, and STD-bus systems. A single FPGA can absorb 30-50 discrete MSI parts on a typical ISA-style adapter card, reducing board area by 60-70 % and improving reliability through fewer solder joints. 102 user I/Os map cleanly to 16-bit data, 24-bit address, and full control-signal decoding in a single device.

Embedded Control Boards & Prototyping
The 144-LQFP package is hand-solderable on 0.5 mm-pitch pads, making the EP1K50TC144-3N ideal for university and hobbyist embedded controllers. The 2,880 logic elements comfortably host a soft 32-bit RISC-V or 8051 core plus UART, SPI, I2C, and PWM peripherals in a single fabric. EABs implement register files and instruction-cache tag RAMs. Quartus II 13.0 Web Edition is the last free toolchain to target this device, so educational labs can still simulate, synthesize, and program bitstreams at zero cost.

Test & Measurement Instrumentation Front-End
Benchtop T&M instruments use the EP1K50TC144-3N as a pattern generator and protocol analyzer front-end. The 166.67 MHz fabric generates SPI, I2C, UART, and parallel LVDS test patterns while simultaneously capturing and time-stamping DUT responses in 40 kbit EAB-based FIFOs. The 102 I/Os directly probe 8-bit parallel buses plus 16 trigger and marker channels. multiVolt I/O simplifies interfacing to 5 V, 3.3 V, and 2.5 V DUTs without external level translation. Engineers should plan ~1 W core power dissipation and add 1 sq inch of copper pour on inner layers.

Diferensiator Kunci
- Fastest available speed grade in the 144-LQFP ACEX-1K family (vsEP1K50TC144-2N)

- Larger embedded memory than smaller-density siblings (vsEP1K30TC144-3N)
Catatan Desain
Estimated: the EP1K50TC144-3N core draws ~250 mA typical at 166.67 MHz with 80 % logic utilization, dissipating roughly 0.6 W. Add a dedicated 2.5 V LDO (e.g. LT1761-2.5 or TPS7A4525) with a 10 µF tantalum bulk and 0.1 µF ceramic decoupling cap within 5 mm of each VCCINT pin. Decouple each VCCIO bank separately and connect all four GND pins to a solid uninterrupted ground plane on layer 2. Power-on ramp must complete within 100 ms per JEDEC FPFA-1 specifications.
Estimated: route all 102 user I/Os on the top layer with 0.15 mm traces and 0.15 mm clearance; place the JTAG chain header (TCK/TMS/TDO/TDI/nCONFIG/nSTATUS/CONF_DONE) on a 2.54 mm pin header for in-system programming access. Maintain 0.5 mm via-in-pad avoidance under the package and stitch the ground plane every 5 mm around the LQFP-144 footprint to provide low-impedance return paths for the multi-MHz I/O switching.
Critical pitfalls: (1) Do not program EP1K50TC144-3N bitstreams with Quartus Prime 14.0 or later — ACEX-1K device support was dropped after Quartus II 13.0; (2) Do not exceed VCCINT above 2.6 V or VCCIO above 3.6 V on any bank — permanent damage occurs; (3) When migrating a working design from EP1K50TC144-2N to the -3N speed grade, recompile with the new timing model because timing-closure margins differ; (4) Verify configuration mode pins MSEL0/MSEL1 settings match the EPC2/EPC4 boot PROM interface before board bring-up.
Informasi Konformitas
