Description

The ultra-low-power STM32L010C6 microcontroller incorporates the high-performance

Arm® Cortex®-M0+ 32-bit RISC core operating at 32 MHz, high-speed embedded memories

(32 Kbytes of Flash program memory, 256 bytes of data EEPROM and 8 Kbytes of RAM)

plus an extensive range of enhanced I/Os and peripherals.

The STM32L010C6 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.

The STM32L010C6 offers several analog features: one 12-bit ADC with hardware

oversampling, several timers, one low-power timer (LPTIM), two general-purpose 16-bit

timers, one RTC and one SysTick that can be used as timebases. The STM32L010C6 also

features two watchdogs, one watchdog with independent clock and window capability, and

one window watchdog based on the bus clock.

Moreover, the STM32L010C6 embeds standard and advanced communication interfaces:

one I2C, one SPI, one USART, and a low-power UART (LPUART).

The STM32L010C6 also includes a real-time clock and a set of backup registers that remain

powered in Standby mode.

The ultra-low-power STM32L010C6 operates from a 1.8 to 3.6 V power supply and in the

–40 to + 85 °C temperature range. A comprehensive set of power-saving modes allows the

design of low-power applications.
