The microcontrollers are in stock at distributor Anglia Components.
This multiprotocol wireless and ultralow power device family embeds a powerful and ultralow power radio compliant with the Bluetooth SIG Low Energy specification 5.4 alongside a high-performance Arm Cortex-M33 32-bit RISC core which operates at a frequency of up to 100 MHz..
The devices integrate a 2.4 GHz RADIO supporting the Bluetooth Low Energy standard and other proprietary protocols if required.
Extended far end communications range is also possible thanks to +10 dBm output power. The Cortex-M33 core features a single-precision floating-point unit (FPU), supporting all the Arm single-precision data-processing instructions and all the data types. The core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security.
Focusing on the Bluetooth Low Energy 5.4 protocol, the STM32WBA series allows non-expert developers to easily add wireless communication to their device at an affordable cost.
Leveraging the STM32U5 architecture, the MCU series is an ultra-low power platform and offers inherited digital and analogue peripherals, suitable for many applications, from industrial, to smart home and consumer markets. The ultra-low power performance of these microcontrollers allows increased battery life especially when using the advertising extension for device communication feature. The realisation of low-power end product designs is further enabled by a comprehensive set of power-saving modes.
The STM32WBA wireless MCU Series embeds large memory to sustain both applications and connectivity activities, coming with up to 1 Mbytes of flash memory and 128 Kbytes of RAM.
A smart set of peripherals like ADC, touch sensing, times, make this product a self-sufficient application wireless MCU.
For IoT devices STMicroelectronics recognise that security is paramount, the microcontrollers offer security foundation compliant with the TBSA (trusted-based security architecture) requirements from Arm.
They embed the necessary security features to implement a secure boot, secure data storage, and secure firmware update.
Besides these capabilities, the devices incorporate a secure firmware installation feature that allows the customer to secure the provisioning of the code during its production.
A flexible life cycle is managed thanks to multiple levels readout protection and debug unlock with password.
