STM32WB05KNV6TR Ultra-low-power, 2.4 GHz network processor, Bluetooth LE 5.4 certified

The STM32WB05xN is an ultra-low-power Bluetooth® LE wireless network coprocessor addressing standard Bluetooth® LE protocol. Interface with external microcontroller can be achieved through SPI and USART. It embeds STMicroelectronics’s state-of-the-art 2.4 GHz radio IPs, optimized for ultra-low-power consumption and excellent radio performance, for unparalleled battery lifetime. It is compliant with Bluetooth® LE.

The STM32WB05xN embeds a Arm® Cortex®-M0+ microcontroller that can operate up to 64 MHz and also the BlueNRG core co-processor (DMA based) for Bluetooth® LE timing critical operations.

The STM32WB05xN features standard and advanced communication interfaces:

The STM32WB05xN operates in the -40 to +105 °C temperature range from a 1.7 V to 3.6 V power supply. A comprehensive set of power-saving modes enables the design of low-power applications.

The STM32WB05xN integrates a high efficiency SMPS step-down converter and an integrated PDR circuitry with a fixed threshold that generates a device reset when the VDD drops under 1.65 V.

The STM32WB05xN comes in different package versions supporting up to:
