STM32L081CBT6 Description
The high-performance Arm Cortex-M0+ 32-bit RISC core, 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 STM32L081xx microcontrollers. High power efficiency is offered by the STM32L081xx 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 STM32L081xx devices include a number of analog features, including a 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, two basic timers, one RTC, and one SysTick that can be used as a timebase. They also have two watchdogs: a window watchdog based on bus clock and a watchdog with separate clock and window functionality.
The STM32L081xx devices also incorporate both conventional and cutting-edge communication interfaces, including up to three I2Cs, two SPIs, four USARTs, and a low-power UART (LPUART).
A real-time clock and a collection of backup registers are also included in the STM32L081xx and are powered on when in Standby mode. The ultra-low-power STM32L081xx devices run on a 1.8 to 3.6 V power supply with BOR and a 1.65 to 3.6 V power supply without BOR option (down to 1.65 V at power down). They are offered in the temperature range of -40 to +125 °C. The development of low-power applications is made possible by a wide range of power-saving modes.
