STM32L081CBT6 Product Details

The access line ultra-low-power STM32L081xx microcontrollers incorporate 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) plus an extensive range of enhanced I/Os and peripherals.

The STM32L081xx 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 STM32L081xx devices offer several analog features, one 12-bit ADC with hardware oversampling, two ultra-low-power comparators, AES, several timers, one low-power timer (LPTIM), four general-purpose 16-bit timers and two 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 STM32L081xx devices embed standard and advanced communication interfaces: up to three I2Cs, two SPIs, four USARTs, a low-power UART (LPUART), .
The STM32L081xx also include a real-time clock and a set of backup registers that remain powered in Standby mode.
The ultra-low-power STM32L081xx 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.
