Drive wireless performance with a cost-effective, multiprotocol ultra-low-power MCU
The high performance of the ultra-low-power STM32WBA25CEU7 wireless MCU from STMicroelectronics is achieved with advanced multiprotocol connectivity and a full set of features.
This 2.4GHz MCU is based on the Arm® Cortex®-M33 RISC core which runs at 64MHz, and offers 512KB Flash memory as well as multiple power options.
The multiprotocol support from the integrated 2.4GHz radio covers Bluetooth® LE 6.2, Zigbee, Thread, and 802.15.4, in addition to offering USB OTG and a quad serial peripheral interface (QSPI) for flexibility and faster data transfer.
The Cortex®-M33 core features a single-precision floating-point unit (FPU), in addition to full digital signal processing (DSP) instructions, and a memory protection unit (MPU).
Security offered by the STM32WBA25CEU7 wireless MCU is compliant with the trusted-based security architecture (TBSA) from Arm. The integrated security features enable secure boot, secure data storage, and secure firmware update. The multi-level readout protection and debug unlock with password manage a flexible life cycle.
The securable peripherals, memories and I/Os, in addition to privilege configuration of peripherals and memories, support the isolation of firmware hardware. There are also protection mechanisms for the embedded Flash memory and 128KB SRAM, with readout protection, write protection, secure, and hide protection areas.
The peripherals which reinforce security are a fast AES coprocessor, a public key accelerator (PKA) with DPA resistance, a HASH hardware accelerator, and a true random number generator. There is also active tamper detection and protection against transient perturbation attacks with several internal monitoring mechanisms generating secret data erasure in the case of an attack.
The radio, communication, analog, and timer peripherals can be functional and autonomous in Stop mode with direct memory access, due to the background autonomous mode (BAM).
