This is a mid-range part in the family — enough headroom for a UART/SPI/I²C protocol bridge, a motor-control loop with PWM and ADC feedback, or a sensor-fusion node that needs deterministic interrupt latency. The 28 available I/O in a 48-VQFN package (7x7 mm) keeps board area tight, and the internal oscillator means one less external component on the BOM.
On-chip ADC and serial interfaces — peripheral fit for control and sensor applications
Eight 10-bit ADC channels give enough resolution for current-sense, temperature, or pressure inputs in a motor-drive or industrial-control design. The connectivity set — I²C, SPI, SSI, Microwire, and UART/USART — covers most serial peripherals without external protocol converters. The PWM and WDT modules round out the peripheral set for real-time control loops that need to run unattended.
For dual-sourcing or second-source planning, the Stellaris family includes pin-compatible density variants, though no official cross-reference is listed in this entry.
