STMICROELECTRONICS STM32WL33CBV7 ARM MCU, STM32 Family STM32WL33xx Series Microcontrollers, ARM Cortex-M0+, 32 bit, 64 MHz, 128 KB

STM32WL33CBV7 is a multiprotocol LPWAN arm-based 32bit microcontroller. It is a high performance ultra-low power wireless application processor, intended for RF wireless applications in the sub-1GHz band. It embeds a wide set of peripherals, including a 20-pin (16 segments + 4 commons) LCD driver, 12bit, 8 channel ADC, analogue comparator, DAC, LC sensor controller, RTC, IWDG, general purpose timers, AES-128, RNG, CRC, communication interfaces such as USART, SPI, and I2C. Moreover, the security features enable secure boot with USART/SWD block (write protection) and sensitive information storage in flash (read-out protection). The integrated highly efficient SMPS step-down converter together with the state transition speed between low-power and active states minimize in every condition the average current consumption enabling the STM32WL33xx to be the wireless application processor most suited for battery-operated applications.
