The STMicroelectronics released STM32WBx5 Dual-core wireless MCU with support of Bluetooth5, Open Thread, and ZigBee3.0. The MCU also features ultra-low-power performance with leveraging the ultra-low-power technologies of the STM32L4line. The STM32WBx5 MCUs features multiple power modes including 13nA Shutdown mode, adaptive voltage scaling, and the adaptive real-time ART Accelerator. The MCUs features large memory of up to 1Mbyte of on-chip Flash and a Quad-SPI port from efficient connection to external memory. The STM32WBx5 comes with security features such as Customer Key Storage(CKS), Public Key Authorization(PKA) and encryption engines for the radio MAC and upper layer.
With focused on ultra-low-power application, The STM32WBx5 is combined with ST’s STM32L4 Arm Cortex-M4 MCUs and in-house radio managed by a dedicated Cortex-M0+. The STM32WBx5 is capable of concurrent wireless-protocol and real time application execution which makes it perfect in areas such as wearable trackers, automation trackers, remote sensors, computer peripherals, drones and other IOT devices. The STM has given free access to developers for an extensive set of tools and rich STM32Cube ecosystem for developing with the STM32WBx5.
The STM32CubeWB MCU Package features peripheral drivers, middleware, and connectivity libraries, and the STM32WB55 Nucleo pack (P-NUCLEO-WB55) with dedicated STM32CubeMon-RF connectivity tool. In addition of security and ultra-low-power features, the MCUs also comes with crystal-less Full-Speed USB, 32MHz RF oscillator with trimming capacitors, a touch-sense controller, LCD controller, analog peripherals, and multiple timers and watchdogs with addition of Balun for antenna connection.
The samples of all devices are available now in a selection of packages from UFQFPN48 up to UFBGA129 and priced from $3.26 for orders of 10,000 pieces and $2 for high-volume orders.
