STM32L071V8T6 Description

The high-performance Arm Cortex-M0+ 32-bit RISC core, operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (up to 192 Kbytes of Flash program memory, 6 Kbytes of data EEPROM, and 20 Kbytes of RAM), as well as a wide variety of enhanced I/Os and peripherals, are all included in the access line ultra-low-power STM32L071xx microcontrollers High power efficiency is offered by the STM32L071xx devices for a variety of performance. A wide variety of internal and external clock sources, an internal voltage adaption, and numerous low-power modes are used to achieve it.

The STM32L071xx devices include a number of analog features, including a 12-bit ADC with hardware oversampling, two ultra-low-power comparators, a number of timers, one low-power timer (LPTIM), four general-purpose 16-bit timers, and two basic timers, one RTC and one SysTick that can be used as timebases. They also have two watchdogs: a window watchdog based on bus clock and a watchdog with separate clock and window functionality.
