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 ...
