Description

The ultra-low-power STM32L010K8/R8 microcontrollers incorporate the high-performance

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

(64 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 STM32L010K8/R8 provide 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 STM32L010K8/R8 offer 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 STM32L010K8/R8

also feature two watchdogs, one watchdog with independent clock and window capability,

and one window watchdog based on the bus clock.

Moreover, the STM32L010K8/R8 embed standard and advanced communication interfaces:

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

The STM32L010K8/R8 also include a real-time clock and a set of backup registers that

remain powered in Standby mode.

The ultra-low-power STM32L010K8/R8 operate 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.
