STMicroelectronics STM32WB09 BLUETOOTH® Low Energy 5.4 32-Bit MCUs
STMicroelectronics STM32WB09 BLUETOOTH® Low Energy 5.4 32-Bit MCUs embed state-of-the-art 2.4GHz RF radio peripherals optimized for ultra-low power consumption and excellent radio performance for unparalleled battery lifetime. The STM32WB09 is compliant with Bluetooth Low Energy SIG core specification version 5.4, managing point-to-point connectivity and Bluetooth Mesh networking, and enables the reliable establishment of large-scale device networks. The STM32WB09 is also ideal for 2.4GHz proprietary radio wireless communication to address ultra-low latency applications.
The STM32WB09 integrates an Arm® Cortex®-M0+ microprocessor that operates up to 64MHz and a radio core coprocessor (DMA-based) for BLE timing critical operations. Additionally, the STM32WB09 supplies enhanced security hardware support through dedicated hardware functions: a true random number generator (TRNG) supporting NIST special publication 800-90B, a security co-processor for 128-bit AES encryption, a CRC calculation unit, a 64-bit unique ID, flash memory read and write protection, and a public key accelerator (PKA).
The STM32WB09 can be configured to support standalone or network processor applications. In the first configuration, the STM32WB09 operates as a single device running the application code and the BLE stack. The STM32WB09 embeds the following high-speed memory types: 512Kbyte flash memory, 64Kbyte RAM, 1Kbyte one-time-programmable (OTP) memory area, and 7Kbyte ROM (ST reserved area). Direct data transfer between memory and peripherals and from memory to memory is supported by eight DMA channels with a complete flexible channel mapping by the DMAMUX peripheral.
The STM32WB09 embeds a 12-bit ADC, allowing measurements of up to eight external and three internal sources, including battery monitoring and a temperature sensor. The STM32WB09 has a low-power RTC and one advanced 16-bit timer. The STM32WB09 features standard and advanced communication interfaces: 1x SPI-I2, LPUART, 1x USART supporting ISO 7816 (SmartCard mode), IrDA and Modbus mode, 2x I2C supporting SMBus/PMBus.
The STM32WB09 operates in the -40°C to +105°C (+125°C junction) temperature range from a 1.7V to 3.6V power supply. A comprehensive set of power-saving modes facilitates the configuration of low-power applications. The STM32WB09 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 1.65V. The STM32WB09 is available in VFQFPN32 and WLCSP36 packages that support up to 20 I/Os.
