STM32WB50CG Multiprotocol Wireless MCU

STMicroelectronics' STM32WB50CG contains a dedicated Arm® Cortex® -M0+ for performing real-time low layer operations

Image of STMicroelectronics' STM32WB50CG Multiprotocol Wireless MCUSTMicroelectronics' STM32WB50CG multiprotocol wireless and ultra-low-power device embeds a powerful and ultra-low-power radio compliant with the Bluetooth® low energy SIG specification v5.0 or with IEEE 802.15.4-2011. It contains a dedicated Arm Cortex-M0+ for performing all the real-time low layer operations. The STM32WB50CG device is designed to be extremely low power and is 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 interprocessor 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 STM32WB50CG device embeds high-speed memories (Flash memory 1 Mbyte, up to 128 Kbyte of SRAM) and an extensive range of enhanced I/Os and peripherals. It features 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 AES encryption engine, 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 device offers one fast 16-bit ADC. Direct data transfer between memory and peripherals and from memory to memory is supported by seven DMA channels with a full flexible channel mapping by the DMAMUX peripheral.

The device also embeds 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. It features standard and advanced communication interfaces, including one USART (ISO 7816, IrDA, Modbus, and Smartcard mode), one I2C (SMBus/PMBus), and one SPI (up to 32 MHz).

The STM32WB50CG operates in the -10°C to +85°C (+105°C junction) temperature range from a 2 V to 3.6 V power supply. A comprehensive set of power-saving modes enables the design of low-power applications. The STM32WB50CG includes independent power supplies for analog input for ADC.

A VBAT dedicated supply allows the device to back up the LSE 32.768 kHz oscillator, the RTC, and the backup registers, thus enabling the STM32WB50CG to supply these functions through a CR2032-like battery, a supercap, or a small rechargeable battery even if the main VDD is not present. The STM32WB50CG is available in a 48-pin UFQFPN package.
