ST STM32WB05KZV6TR

The STM32WB05xZ is an ultra-low power programmable Bluetooth Low Energy wireless SoC solution. It embeds 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 addressing point-to-point connectivity and Bluetooth Mesh networking and allows large-scale device networks to be established in a reliable way. The STM32WB05xZ is also suitable for 2.4 GHz proprietary radio wireless communication to address ultra-low latency applications. The STM32WB05xZ embeds a Arm Cortex-M6+ microcontroller that can operate up to 64 MHz and also the BlueNRG core co-processor (DMA based) for Bluetooth Low Energy timing critical operations. In addition, the STM32WB05xZ provides enhanced security hardware support by dedicated hardware functions: True random number generator (RNG), encryption AES maximum 128-bit security co-processor, HW public key accelerator (PKA), and cryptographic algorithms: RSA, Diffie-Helman, ECC over GF(p).
