The LM3S1960-IQC50-A2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 1000 series, running at 50 MHz with 256 KB of Flash and 64 KB of RAM. The internal oscillator and brown-out detect / POR / WDT peripherals reduce external component count for a compact industrial controller board.
NRND lifecycle — what it means for procurement
This is the official signal from Texas Instruments that the part is in the phase-out pipeline. The NRND flag means procurement should evaluate a last-time-buy quantity or qualify an alternative. The 100-LQFP footprint and 2.25 V–2.75 V supply narrow the field.
The 50 MHz clock rate on this Cortex-M3 delivers throughput for moderate-speed control loops. It is not a high-end part for DSP work.
