EP1K50TI144-4 Ringkasan

The Altera (now Intel) EP1K50TI144-4 is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs) housed in a 144-pin TQFP package. Built on a 2.5 V CMOS process, the EP1K50 family integrates up to 50,000 typical gates, 2,880 logic elements (LEs), and 40,960 bits of embedded array (EAB) SRAM organized into 5 Embedded Array Blocks. The device provides 102 user I/O pins plus 6 dedicated input pins, supporting a maximum clock frequency of 90 MHz at the -4 speed grade.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows hardware designers to configure digital logic blocks, interconnects, and I/O after manufacture. FPGAs sit within the broader category of programmable logic devices (PLDs), alongside CPLDs and SPLDs, and are widely used for glue logic, prototyping, custom interfaces, signal processing pipelines, and ASIC emulation. The ACEX 1K family specifically targets low-cost, high-volume applications where traditional gate-array ASICs are uneconomical.

Key features of the EP1K50TI144-4 include 2,880 logic elements, 40,960 bits of embedded SRAM, MultiVolt I/O supporting 2.5 V and 3.3 V interfacing on the same die, and 6 dedicated clock/abort input pins. The -4 speed grade places it in the slower tier of the family, but this is acceptable for industrial glue logic, peripheral bridging, and parallel interface expansion. The TQFP-144 package (0.5 mm pitch) is a plastic surface-mount land-grid-compatible outline allowing hand-rework and visual inspection.

Typical applications include industrial control interfaces, parallel bus bridges, custom peripheral controllers, telecommunications line cards (legacy designs), and ASIC prototyping. The wide operating voltage tolerance (2.375 V to 2.625 V core) combined with 3.3 V-tolerant I/O makes it a flexible bridge between older 5 V-tolerant peripherals and modern 2.5 V cores when used with external level shifters.

Designers should note that the ACEX 1K family is now legacy. Quartus II software is required for design entry, and the EP1K50TI144-4 is supported in legacy toolchains. New designs should evaluate Cyclone series or MAX II CPLDs for equivalent functionality with modern tool support.

This page synthesizes pricing data from active distributors, drop-in compatible ACEX 1K speed-grade and package alternatives, and practical design notes not found in the original datasheet, helping engineers source and migrate from this legacy FPGA.
