STM32L011F4U3TR Overview

Reset and supply management

The access line ultra-low-power STM32L011x3/4 family incorporates the high-performance Arm? Cortex?-M0+ 32-bit RISC core operating at a 32 MHz frequency, high-speed embedded memories (up to 16 Kbytes of Flash program memory, 512 bytes of data EEPROM and 2 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.
The STM32L011x3/4 devices provide high power efficiency for a wide range of performance. It is achieved with a large choice of internal and external clock sources, an internal voltage adaptation and several low-power modes.
The STM32L011x3/4 devices offer several analog features, one 12-bit ADC with hardware oversampling, two ultra-low-power comparators, several timers, one low-power timer (LPTIM), three general-purpose 16-bit timers, one RTC and one SysTick which can be used as timebases. They also feature two watchdogs, one watchdog with independent clock and window capability and one window watchdog based on bus clock.
Moreover, the STM32L011x3/4 devices embed standard and advanced communication interfaces: one I2C, one SPI, one USART, and a low-power UART (LPUART).
The STM32L011x3/4 also include a real-time clock and a set of backup registers that remain powered in Standby mode.
The ultra-low-power STM32L011x3/4 devices operate from a 1.8 to 3.6 V power supply (down to 1.65 V at power down) with BOR and from a 1.65 to 3.6 V power supply without BOR option. They are available in the -40 to +125 °C temperature range. A comprehensive set of power-saving modes allows the design of low-power applications.
