Description
The STM32WB05xN is an ultra-low-power Bluetooth® Low Energy wireless network coprocessor addressing standard Bluetooth® LE protocol. Interface with external micro controller 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 Low Energy SIG core specification version 5.4.
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 Low Energy timing critical operations.
The STM32WB05xN features standard and advanced communication interfaces:
- 1x SPI
- 1x USART
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:
- 20 I/Os for the VFQFPN32 package
- 20 I/Os for the WLCSP36 package
-
