STMicroelectronics STM32WL33K8V7, 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. It adopts a single-core architecture embedding an Arm® 32-bit Cortex®-M0+ CPU that can operate up to 64 MHz. It integrates high-speed and flexible memory types: up to 256 Kbyte flash memory, and up to 32 Kbyte RAM, onetime programmable (OTP) memory area of 1 Kbyte. 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.
