It operates from -40°C to 105°C and requires a 2.25 V to 2.75 V supply. ## 50 MHz Cortex-M3 — what the speed buys you At 50 MHz the core delivers enough performance for a Modbus RTU slave stack and a PID loop. The 46 GPIOs and 2x10-bit ADC handle slow analog channels. ## Lifecycle reality — NRND, not for new BOM lines There is no listed official successor in this evidence. For a BOM line that must stay active for years, a current-production Stellaris or Tiva-C family member should be evaluated. ## Package and mounting — 100-LQFP Housed in a 100-LQFP (14x14 mm), surface-mount only. The 46 I/O are distributed around the four sides.","metaTitle":"LM3S1162-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"LM3S1162-EQC50-A2T from Texas Instruments: Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 16 KB RAM, -40 to 105°C.
