Product details

What this Stellaris Cortex-M3 brings to a control board

The Texas Instruments LM3S301-IGZ20-C2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 300 series, clocked at 20 MHz with 16 KB of Flash and 2K x 8 of RAM. It carries 33 general-purpose I/O lines and a 3-channel 10-bit ADC, plus serial interfaces covering Microwire, SPI, SSI, and UART/USART — enough connectivity to talk to common sensors, small displays, or a Modbus gateway. The internal oscillator keeps the BOM simple for applications that do not need a precision external clock.
