EP1K50TI144-2X Ringkasan

The Intel EP1K50TI144-2X is a 50,000-gate Field Programmable Gate Array from the ACEX 1K family, housed in a 144-pin TQFP (Industrial temperature grade) package. The device integrates 2,880 logic elements organized as 360 Configurable Logic Blocks (LABs/CLBs), 40,960 bits of embedded SRAM, and 102 maximum user I/O pins. The '2X' speed grade designation places it in Altera's mid-range performance tier for this family.

ACEX 1K is Altera's low-cost, SRAM-based FPGA family that bridges the gap between CPLDs and high-density FPGAs. As a field programmable gate array, an ACEX 1K device stores its configuration in volatile SRAM cells that must be loaded from an external PROM or controller at every power-up. The architecture combines look-up table (LUT)-based logic with embedded memory blocks, providing designers with a balance of logic density and on-chip storage for glue logic, bus interfacing, and small state-machine implementations.

Key features of the EP1K50TI144-2X include a maximum operating frequency up to 833 MHz on internal paths, true LVTTL/LVCMOS/PCI-compliant I/O with user-configurable slew rate and drive strength, on-chip impedance matching, and built-in JTAG (IEEE 1149.1) boundary-scan support for board-level testing. The embedded array blocks (EABs) provide dedicated RAM/ROM functionality with widths up to 16 bits.

The EP1K50TI144-2X uses a 0.18 µm CMOS process and operates from a 2.5 V core supply (VCCINT) with separate VCCIO banks that support mixed-voltage I/O standards (3.3 V, 2.5 V, 1.8 V). Industrial temperature grade parts (suffix 'I') are guaranteed across -40 °C to +100 °C operation, making the part suitable for non-automotive industrial, telecom, and instrumentation applications. Designers configure the device using Altera's MAX+PLUS II or Quartus development software, both of which support schematic, VHDL, and Verilog entry with synthesis, fitting, and timing analysis.

Typical applications include industrial control interfaces, glue logic for legacy system upgrades, custom peripheral controllers in telecom equipment, low-density data-path acceleration, and prototyping vehicles for newer Cyclone/MAX 10 designs. The 144-pin TQFP with 0.5 mm pitch remains a familiar through-hole-friendly footprint for engineers migrating away from larger BGA-only devices.

When designing with this part, ensure the configuration source (EPC2, EPC4, or microcontroller) matches the FPGA's 2.5 V VCCINT requirement and that JTAG chain integrity is preserved. Designers planning long-term production should note that ACEX 1K is a mature legacy family; current production designs should target Cyclone IV, MAX 10, or MAX V devices instead.
