STM32L053C8T6TR

STM32L053C8T6TR is a ultra-low-power 32-bit MCU. The device provides 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. It offers several analogue features, one 12-bit ADC with hardware oversampling, one DAC, two ultra-low-power comparators, several timers, one low-power timer (LPTIM), three general-purpose 16-bit timers and one basic timer, 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. It includes a real-time clock and a set of backup registers that remain powered in standby mode. Applications include gas/water meters and industrial sensors, healthcare and fitness equipment, remote control and user interface, PC peripherals, gaming, GPS equipment, alarm system, wired and wireless sensors, video intercom.
