Description

The ultra-low-power STM32L062x8 microcontrollers incorporate the connectivity power of

the universal serial bus (USB 2.0 crystal-less) with 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 (64 Kbytes of Flash program memory, 2 Kbytes of data

EEPROM and 8 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.

The STM32L062x8 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 STM32L062x8 devices offer several analog features, one 12-bit ADC with hardware

oversampling, one DAC, two ultra-low-power comparators, AES, 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.

Moreover, the STM32L062x8 devices embed standard and advanced communication

interfaces: up to two I2Cs, one SPI, two USARTs, a low-power UART (LPUART), and a

crystal-less USB. The devices offer up to 14 capacitive sensing channels to simply add

touch sensing functionality to any application.

The STM32L062x8 also include a real-time clock and a set of backup registers that remain

powered in Standby mode.

The ultra-low-power STM32L062x8 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.
