The ultra-low-power STM32L010F4/K4 microcontrollers incorporate the high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at 32 MHz, high-speed embedded memories (16 Kbytes of Flash program memory, 128 bytes of data EEPROM and 2 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.
The STM32L010F4/K4 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 STM32L010F4/K4 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 STM32L010F4/K4 also feature two watchdogs, one watchdog with independent clock and window capability, and one window watchdog based on the bus clock.
Moreover, the STM32L010F4/K4 embed standard and advanced communication interfaces: one I2C, one SPI, one USART, and a low-power UART (LPUART).
The STM32L010F4/K4 also include a real-time clock and a set of backup registers that remain powered in Standby mode.
The ultra-low-power STM32L010F4/K4 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.
