The LM3S817-EGZ50-C2T: 32-bit ARM Cortex-M3 MCU from the Stellaris 800 series, clocked at 50 MHz with 64 KB of Flash and 8 KB of RAM.
50 MHz core handles a UART-to-SPI bridge, a PWM motor phase loop, and a 10-bit ADC scan. Internal oscillator saves a crystal BOM line.
PWM module and watchdog are on-chip.
Rated for -40°C to 105°C ambient, which covers industrial enclosures, motor drives, and outdoor telecom gear.
