STM32WBA6 2.4-GHz wireless MCUs from ST offer increased memory and digital system interfaces for high-end applications in smart home, health, factory, and agriculture. Based on an energy-efficient Arm Cortex-M33 core running up to 100 MHz, the devices provide up to twice the flash and RAM of the previous STM32WBA5 series for application code and data storage.
With up to 2 MB of flash and 512 KB of RAM on-chip, the STM32WBA6 MCUs are able to support more advanced applications. Digital peripherals include high-speed USB, three SPI ports, four I2C ports, three USARTs, and one LPUART. By integrating the processing core, peripherals, and wireless subsystems, the MCUs streamline designs and reduce assembly size.
The STM32WBA6 wireless subsystem supports Bluetooth LE, Zigbee, Thread, and Matter, enabling concurrent communication across multiple protocols. It also enhances performance, with sensitivity increased to -100 dBm for more reliable connectivity up to the maximum specified range.
The STM32WBA6 wireless MCUs are in production and available now, priced from $2.50 each in lots of 10,000 units.
