Low-power wireless MCU in stock at Anglia

It is in stock at authorised 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.

For IoT devices STMicroelectronics recognise that security is paramount, the STM32WBA Series 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.

Focusing on the Bluetooth Low Energy 5.4 protocol, the MCU series allows non-expert developers to easily add wireless communication to their device at an affordable cost. Leveraging the STM32U5 architecture, the STM32WBA series is an ultra-low power platform and offers inherited digital and analog 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 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.

The MCU is offered in two packages: UFQFPN in 32 pin 5 x 5 mm and 48 pin 7 x 7 mm, or UFBGA in 59 pin 5 x 5 mm. Devices have an operating temperature range of -40 °C to 85 °C (105 °C junction) and operate from a 1.71 to 3.6 V power supply.

The STM32WBA MCU series is also included in STMicroelectronics 10-year Longevity Program giving developers the reassurance to use the product in new designs.

The NUCLEO-WBA52CG development board allows designers to quickly explore all the features of the microcontroller and accelerate development time.

It features the microcontroller with Bluetooth Low Energy wireless and ultra-low-power embedding a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy SIG specification v5.4. The board has ARDUINO Uno V3 connectivity support and the ST morpho headers allow the easy expansion of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The development board is fully supported by the proven STM32Cube ecosystem which helps fasten time-to market.
