The Texas Instruments LM3S1J16-IQR50-C0T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 1000 series, clocked at 50 MHz.
On-chip peripherals include brown-out detect, POR, PWM, WDT, and a DMA controller. With 33 GPIOs in the 64-pin package, the I/O count is tight but workable for a focused control or data-acquisition role.
