ST simplifies wireless MCUs for Bluetooth 5.2

STMicroelectronics has further stripped down the memory in its STM32WBxx wireless microcontroller family to reduce cost in Bluetooth 5.2 applications. STM32WB15 and STM32WB10 retain the Arm Cortex-M4 application processor and paired Cortex-M0+ Bluetooth 5.2 stack processor, but come with: 320kbyte flash for stack and application – with sector protection against R/W operations, 48kbyte SRAM – 36kbyte has ...
