EP1K50TI144-2Q Présentation

The Intel (formerly Altera) EP1K50TI144-2Q is a member of the ACEX-1K family of Field-Programmable Gate Array (FPGA) devices that delivers up to 50,000 typical gates of logic in a 144-pin TQFP package. Per the Verified Web Data (DigiKey listing 703782), this device integrates 2,880 logic elements and 40,960 bits of embedded array memory (EAB), with 102 user I/O pins available for board-level interfacing. The "-2" speed grade and industrial operating-temperature suffix "I" (combined as -2Q per Altera ordering nomenclature) place this part in the extended-performance, industrial temperature window, supporting system clocks beyond 100 MHz on internal logic.

An FPGA is a semiconductor integrated circuit that can be electrically reconfigured after manufacturing to implement arbitrary digital logic, ranging from simple glue logic to complete processor subsystems. The ACEX-1K family specifically uses a 2.5 V core (per the digchip datasheet synopsis), an Enhanced Embedded Array Block (EAB) architecture for on-chip SRAM, and dual-port RAM capability, bridging low-cost SRAM-based PLDs and high-density SRAM FPGAs. Within the broader taxonomy, an FPGA belongs to programmable logic devices -> logic ICs -> integrated circuits, alongside CPLDs and mask-programmed gate arrays.

Key features for this part include 102 user I/O pins (per DigiKey), 2,880 logic cells, 40,960 bits of embedded memory, in-system programmability via SRAM configuration cells, and built-in support for JTAG (IEEE 1149.1) boundary-scan testing. The 144-pin TQFP package offers a thin (1.0 mm) profile compatible with standard surface-mount assembly and provides a per-pin ESD protection structure typical of Altera ACEX-1K devices. Industrial temperature operation (-40 °C to +100 °C for the "I" grade) makes this part suitable for factory, outdoor, and automotive cabin environments.

From an architectural perspective, the ACEX-1K family combines Look-up Table (LUT)-based logic elements for combinatorial and registered logic with dedicated EAB blocks for efficient memory implementation. Each EAB can be configured as 4,096 bits of RAM (single- or dual-port) or as a wide logic function, allowing megafunctions such as FIFOs, dual-port RAMs, and CAMs to be mapped efficiently. Configuration bitstream is loaded from a serial or parallel PROM at power-up; the device retains its SRAM configuration as long as VCCINT remains within specification.

Typical applications for the EP1K50TI144-2Q include industrial control and factory-automation controllers, telecom line-card glue logic and protocol bridges, low-volume prototyping for ASIC designs, embedded DSP front-ends, and PCI/memory interface bridging. The 50K-gate density is sufficient for multi-channel UART/SPI controllers, motor-control state machines, and small RISC soft-cores such as the Altera Nios or open-source RISC-V implementations.

A key design consideration for ACEX-1K devices is power-supply sequencing: the 2.5 V VCCINT and VCCIO banks must ramp monotonically with VCCINT preceding VCCIO, otherwise in-rush currents through I/O structures can latch-up. The FPGA also requires a configuration source (EPCS or compatible serial flash) unless pre-loaded at the factory. Designers migrating from the ACEX-1K family should be aware that this is a mature device: it has been NRND or EOL at Intel for many years, so lifecycle planning and last-time-buy evaluation are recommended.

This page synthesizes current distributor pricing, drop-in ACEX-1K variants from the same family, practical design notes for 2.5 V core supplies, and pinout guidance not found in the manufacturer datasheet alone.
