The STM32WB55xx multiprotocol wireless and ultra-low-power devices embed a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy SIG specification v5.0 and with IEEE 802.15.4-2011. They contain a dedicated Arm® Cortex® -M0+ for performing all the real-time low layer operation.
The STM32WB55xx devices are designed to be extremely low-power and are based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 64 MHz. The Cortex®-M4 core features a Floating point unit (FPU) single precision that supports all Arm® single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) that enhances application security.
Enhanced inter-processor communication is provided by the IPCC with six bidirectional channels. The HSEM provides hardware semaphores used to share common resources between the two processors.
The STM32WB55xx devices embed high-speed memories (Flash memory up to 1 Mbyte, up to 256 Kbyte of SRAM), a Quad-SPI Flash memory interface (available on all packages) and an extensive range of enhanced I/Os and peripherals.
Direct data transfer between memory and peripherals and from memory to memory is supported by 14 DMA channels with a full flexible channel mapping by the DMAMUX peripheral.
The STM32WB55xx devices embed several mechanisms for embedded Flash memory and SRAM: readout protection, write protection and proprietary code readout protection. Portions of the memory can be secured for Cortex® -M0+ exclusive access.
The two AES encryption engines, PKA and RNG enable lower layer MAC and upper layer cryptography. A customer key storage feature may be used to keep the keys hidden.
The devices offer one fast 16-bit ADC and two ultra-low-power comparators associated with a high accuracy reference voltage generator.
The STM32WB55xx devices embed a low-power RTC, one advanced 16-bit timer, one general-purpose 32-bit timer, two general-purpose 16-bit timers, and two 16-bit low-power timers.
In addition, up to 28 capacitive sensing channels are available. The devices also embed an integrated LCD driver up to 8x40 or 4x44, with internal step-up converter.
They also feature standard and advanced communication interfaces:
The STM32WB55xx operate in the -40 to +105 °C (+125 °C junction) temperature range from a 1.71 to 3.6 V power supply. A comprehensive set of power-saving modes enables the design of low-power applications.
The STM32WB55xx integrate a high efficiency SMPS step-down converter. It includes independent power supplies for analog input for ADC and comparators, as well as a 3.3 V dedicated supply input for USB.
A VBAT dedicated supply allows the devices to back up the LSE 32.768KHz oscillator, the RTC and the backup registers, thus enabling the STM32WB55xx to supply these functions even if the main VDD is not present through a CR2032-like battery, a Supercap or a small rechargeable battery.
The STM32WB55xx family offers three packages, from 48 to 100 pins.
