On-chip brown-out detect, POR, PWM, and a watchdog timer reduce external supervisor IC count. Connectivity covers Microwire, SPI, SSI, and UART/USART — enough to talk to common serial ADCs, DACs, or radio modules.","metaTitle":"LM3S101-EQN20-C2T Stellaris ARM Cortex-M3 MCU, 20 MHz, 8 KB Flash","metaDescription":"LM3S101-EQN20-C2T 32-bit ARM Cortex-M3 MCU, 20 MHz, 8 KB Flash, 2 KB SRAM, 18 I/O, -40 to 105°C, 48-LQFP.
