描述
The STM32WBA2xxx multiprotocol wireless and ultra-low-power devices embed a powerful and ultra-low-power 2.4 GHz RADIO compliant with the Bluetooth® LE specifications and with IEEE 802.15.4-2015. They contain a high-performance Arm® Cortex®-M33 32-bit RISC core. They operate at a frequency of up to 64 MHz.
The devices integrate a 2.4 GHz RADIO supporting Bluetooth® LE, Thread®, and Zigbee®. It provides support for an array of up to eight antennas and an external power amplifier. The PTA (packet traffic arbitration) interface is supported.
The Cortex®-M33 core features a single-precision floating-point unit (FPU), supporting all the Arm single-precision data-processing instructions and all the data types. This core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security.
The devices embed high-speed memories (512 Kbytes of flash memory and 96 Kbytes of SRAM), one Quad-SPI memory interface, and a range of enhanced I/Os and peripherals connected to AHB and APB buses on the 32-bit multi-AHB bus matrix.
The devices offer a security foundation compliant with the TBSA (trusted-based security architecture) requirements from Arm. It embeds the necessary security features to implement a secure boot, secure data storage, and secure firmware update. A flexible life cycle is managed through multi-level readout protection and debug unlock with password.
Firmware hardware isolation is supported using securable peripherals, memories and I/Os, and privilege configuration of peripherals and memories.
The devices feature several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, secure, and hide protection areas.
The devices embed several peripherals reinforcing security: a fast AES coprocessor, a PKA (public key accelerator) with DPA resistance, a HASH hardware accelerator, and a true random number generator.
The devices offer 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 devices offer one 12-bit ADC (2.5 Msps), a low-power RTC, one 32-bit and two 16-bit general-purpose timers, and two 16-bit low-power timers. They also feature standard and advanced communication interfaces, namely two I2Cs, one SPI, one SAI, one USART and one low-power UART, and one full-speed Host- and Device-capable USB. The feature set is product-dependent.
The devices operate in the -40 to 85 °C and -40 to 105 °C temperature ranges from a 1.71 to 3.6 V power supply.
The design of low-power applications is enabled by a comprehensive set of power-saving modes.
Many peripherals (including radio, communication, analog, and timer peripherals) can be functional and autonomous in Stop mode with direct memory access thanks to BAM (background autonomous mode) support.
Some independent power supplies are supported, like an analog independent supply input for ADC, a 3.3 V dedicated supply input for USB, and radio-dedicated supply inputs for the 2.4 GHz RADIO.
The devices offer three packages, up to 48 pins, with or without SMPS.
