The Texas Instruments LM3S1162-EQC50-A2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris® 1000 series, clocked at 50 MHz with 64 KB of Flash program memory and 16 KB of SRAM. 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.
