STMicroelectronics STM32L010RB ultra-low-power Arm Cortex-M0+ MCU

The ultra-low-power STM32L010RB microcontroller incorporates the high-performance Arm^® Cortex^®-M0+ 32-bit RISC core operating at 32 MHz, high-speed embedded memories (128 Kbytes of Flash program memory, 512 bytes of data EEPROM and 20 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.

The STM32L010RB provides high power efficiency over a wide performance range. This is achieved with a large choice of internal and external clock sources, internal voltage adaptation, and several low-power modes.
