EP1K50TC144-2N Visão geral
An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can configure after manufacture to implement custom digital logic functions. The ACEX-1K family sits in the broader taxonomy: FPGA → programmable logic device (PLD) → logic IC → integrated circuit (IC). ACEX-1K was Altera's low-cost, 2.5 V alternative positioned between CPLDs and higher-density SRAM-based FPGAs such as APEX 20K and Stratix.
Key features of the EP1K50TC144-2N include 2,880 logic elements, 50,000 typical gates (up to 100,000 maximum), 12 embedded array blocks (EABs) of 4,096 bits each for dual-port RAM, ROM, or FIFO implementation, fast propagation delay in the nanosecond class, JTAG-compliant boundary-scan test support, and a 0.4 ns internal speed grade (the "-2" suffix). The device supports in-system programming via the serial configuration scheme and supports multiple I/O standards including LVTTL, LVCMOS, and PCI.
The device implements an enhanced embedded array structure where each EAB block provides up to 4,096 bits of dual-port RAM, enabling efficient memory and specialized logic functions such as multipliers, finite impulse response (FIR) filters, and microcontrollers in a single chip. This architecture allows SOPC (System-on-a-Programmable-Chip) integration with megafunctions, reducing overall system cost and board area for designs that previously required separate logic and memory chips.
Typical applications for the EP1K50TC144-2N include glue logic replacement, telecommunications interface bridging, industrial control and factory automation subsystems, prototype ASIC emulation, and digital signal processing (DSP) front-end pre-processing. It is also used in legacy telecom line cards, military/aerospace control electronics, and educational FPGA platforms where its 144-LQFP through-hole-friendly footprint simplifies laboratory rework and programming.
When designing with this device, designers must ensure proper decoupling on all VCCINT (2.5 V core) and VCCIO (3.3 V/2.5 V/1.8 V I/O) rails, use a configuration device or JTAG programmer for bitstream loading, and respect the maximum supported clock frequency at the chosen speed grade. The part is now in the Altera/Intel legacy product line, so lifecycle planning should consider migration to Cyclone or Cyclone II equivalents for new designs.

Aplicações típicas
EP1K50TC144-2N é adequado para 6 aplicaçãos: Telecommunications Line Card Interface, Industrial Control and Factory Automation, ASIC Prototyping and Logic Emulation, Digital Signal Processing Front-End Pre-Processing, Legacy Computer Bus Interface Bridging, Educational FPGA Training Platforms.
Telecommunications Line Card Interface
The EP1K50TC144-2N's 2,880 logic elements, 40,960 bits of dual-port EAB memory, and 102 user I/Os make it ideal for telecom line card interface bridging where it implements TDM/PCM framers, channel aggregation, and protocol adaptation. The 50K-gate capacity supports multi-channel DS1/E1 framers plus glue logic for legacy parallel bus peripherals, while the 144-LQFP package simplifies through-hole rework in lab environments. Operating at 2.5 V core with 3.3 V-tolerant I/O, the device interfaces directly to legacy 3.3 V framer ASICs. Its 200 MHz internal frequency and 0.4 ns speed-grade delay comfortably meet the timing budget for serial-to-parallel conversion at typical telecom clock rates. Engineers should plan for migration to Cyclone or Cyclone II for new line card designs.
Recomendado
Industrial Control and Factory Automation
In industrial control systems, the EP1K50TC144-2N serves as a flexible logic platform implementing PLC scan engines, motor control state machines, and fieldbus protocol bridges (Profibus, Modbus, CANopen). Its 360 LABs and 12 EABs provide sufficient density for typical PLC ladder-logic translation, while the 102 I/Os accommodate parallel industrial sensor and actuator interfaces. The commercial temperature grade (N suffix) and surface-mount TQFP-144 form factor suit factory-floor controller boards with adequate thermal management. The 2.5 V core draws less power than 5 V predecessors, easing thermal budgets in sealed enclosures. Note: industrial designs requiring extended temperature range should specify the I-suffix variant instead of the N-suffix.
Recomendado
ASIC Prototyping and Logic Emulation
Designers use the EP1K50TC144-2N as a cost-effective ASIC prototype platform for sub-50K-gate designs in pre-silicon validation flows. The device's 2,880 logic elements, 40,960 bits of EAB memory, and Quartus-supported synthesis flow allow direct compilation of RTL testbenches into the FPGA, providing real-time hardware verification of ASIC netlists at MHz-class speeds. Its 144-LQFP package and through-hole-friendly footprint simplify benchtop rework and signal probing during bring-up. The 0.22 µm process and 2.5 V core deliver modest dynamic power at 200 MHz internal frequencies, suitable for desktop verification chassis. Pair with JTAG-based configuration for iterative design cycles.
Recomendado
Digital Signal Processing Front-End Pre-Processing
The EP1K50TC144-2N handles DSP front-end tasks such as FIR filtering, FFT pre-conditioning, and data-rate conversion in embedded signal processing subsystems. Each EAB block (4,096 bits) implements dual-port RAM ideal for coefficient storage in FIR filter banks, while the 360 LABs implement MAC-style arithmetic datapaths for sample-rate conversion. The 200 MHz internal clock rate and 0.4 ns propagation delay support intermediate-frequency sample processing in instrumentation and control loops. The 144-LQFP package is breadboard-friendly for university and research lab DSP prototyping. For production DSP designs, migrate to Cyclone II or Cyclone III for higher density and lower power.
Recomendado
Legacy Computer Bus Interface Bridging
The EP1K50TC144-2N is widely deployed in legacy computer bus bridging applications between ISA, PCI, VME, and proprietary backplanes. Its 102 user I/Os support multi-byte parallel bus interfaces plus control/handshake signals, while the 12 EABs implement FIFOs for rate matching between asynchronous bus domains. The 2.5 V/3.3 V mixed-voltage I/O capability allows direct interfacing to legacy 5 V-tolerant peripherals via external bus transceivers. The commercial temperature grade matches data-center and laboratory environments where legacy VME systems still operate. With ACEX-1K in NRND status, plan migration paths to Cyclone series for new bridge designs.
Recomendado
Educational FPGA Training Platforms
Universities and training centers use the EP1K50TC144-2N in FPGA curriculum development kits because of its 144-LQFP through-hole-friendly footprint, which simplifies student hand-soldering and rework during lab exercises. The 50K-gate capacity is sufficient for teaching all core FPGA concepts - state machines, FIFOs, soft-core processors, and basic DSP - without overwhelming students with tool complexity. The ACEX-1K family is supported by older Altera Quartus versions still compatible with educational lab PCs. The commercial temperature grade and 2.5 V core simplify lab power supply design. Modern curricula are migrating to Cyclone or Cyclone IV boards, but legacy EP1K50TC144-2N labs remain in operation worldwide.

Notas de projeto
The EP1K50TC144-2N requires a clean 2.5 V supply on VCCINT pins and a separate 2.5 V or 3.3 V supply on VCCIO pins (one rail per I/O bank). Place 0.1 µF ceramic decoupling capacitors as close as possible to every VCCINT and VCCIO pin, with bulk 10 µF tantalum or ceramic caps on each supply near the FPGA. Estimated: with all 102 I/Os switching at 50 MHz, ICCINT can reach ~200 mA; ensure the regulator supplies at least 500 mA of margin. Power sequencing requires VCCINT to ramp before or simultaneously with VCCIO.
The TQFP-144 package has a 0.5 mm pin pitch, which requires fine-pitch PCB layout techniques: 0.15 mm trace/space design rules, micro-vias for breakout, and a 4-layer stack-up with dedicated ground and power planes. Place the configuration device (e.g., EPC2) within 50 mm of the FPGA to minimize DCLK/Data trace length and avoid signal-integrity issues at high configuration clock rates. Keep JTAG signals (TCK/TMS/TDI/TDO) on a separate routing layer or guarded by ground pours to prevent coupling with switching I/O.
Do not leave nCONFIG floating during power-up - this pin has a weak internal pull-up but must be tied to VCCIO via a 1 kΩ resistor for reliable configuration. Ensure CONF_DONE has an external 1 kΩ pull-up to VCCIO, as the device releases this pin only after successful configuration. Avoid exceeding the maximum I/O count claim (102 pins); bank conflicts can occur if VCCIO is shared between incompatible I/O standards. The "N" suffix denotes commercial temperature (0°C to +70°C) - for industrial applications, use the I-suffix variant instead.
