The STM32WBA MCU series brings designers performance, efficiency, and flexibility. It embeds large memory to sustain both applications and connectivity activities, coming with up to 2 Mbytes of flash memory and up to 512 Kbytes of RAM. A smart set of peripherals like ADC, touch sensing, and timers make this product a self-sufficient application wireless MCU.

• High data rate to ensure fast and reliable data transfer
• Multi-protocol flexibility (Bluetooth^® LE*, IEEE 802.15.4 communication protocols,Zigbee^®,Thread andMatter)
• Long range capability to enlarge communication range
• High output power to increase communication range thanks to +10 dBm of output power
• Low-powermessaging capability to extend battery lifetime
