EP1K50TC144-2N Présentation

The Altera (now Intel) EP1K50TC144-2N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), delivering 50,000 typical gates and 2,880 logic elements in a 144-pin LQFP (TQFP-144) commercial-grade package. It integrates 102 user I/Os, 40,960 bits of embedded RAM (EAB blocks), 360 Logic Array Blocks (LABs), and operates at up to 200 MHz internal frequency with 0.22 µm CMOS process technology on a 2.5 V core supply.

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.

This page synthesizes distributor pricing, drop-in alternative MPNs, and practical design notes that are not consolidated in the manufacturer datasheet PDF, providing engineers with a single source for procurement and second-source decisions.
