STMicroelectronics STM32WL33CCV7, 32 bit ARM 32 Bit Cortex M0, STM32WL33xx Microcontroller, 958 MHz, 256kB FLASH, 32-Pin

The STMicroelectronics STM32WL33xx is a high performance ultra-low power wireless application processor, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate in both the license-free ISM and SRD frequency bands such as 433, 868, and 915 MHz. Direct data transfer between memory and peripherals and from memory-to-memory is supported by seven DMA channels with fully-flexible channel mapping by the DMAMUX peripheral. It operates in the -40 to +105 °C temperature range from a 1.7 V to 3.6 V power supply. A comprehensive set of power-saving modes enables the design of low-power applications.
