Overview

Description

STM32L100RCT6TR is an ultra-low-power 32‑bit MCU from STMicroelectronics’ STM32L1 family, built around an ARM Cortex‑M3 core. It targets battery-operated and energy‑aware applications, delivering long life through multiple low‑power modes and efficient peripherals. The device typically includes Flash memory, SRAM, and a versatile set of peripherals (timers, ADCs, and multiple serial interfaces such as UART/SPI/I2C, plus other analog features). The RCT6TR suffix denotes specific packaging, temperature range, and reel packaging. For exact memory size, peripheral options, operating voltage, and electrical characteristics, consult the STM32L100RCT6TR datasheet and reference manual from ST.
