STMicroelectronics RF and Wireless - RF Transceiver ICs STM32WB15CCU6

The STM32WB15CCU6 is a multiprotocol wireless 32-bit microcontroller featuring an Arm Cortex-M4 core with a floating-point unit (FPU) and a Bluetooth 5.3 radio solution. It operates in the 2.4 GHz frequency range and supports Bluetooth Low Energy with a receive sensitivity of -95.5 dBm at 1 Mbps. The device allows programmable output power up to +5.5 dBm in 1 dB steps and includes an integrated balun to minimize bill of materials (BOM) costs. This microcontroller is designed for ultra-low-power applications, with a supply voltage range of 1.71 to 3.6 V and various low-power modes, including a shutdown mode consuming only 12 nA. In active mode, it consumes 33 µA per MHz when both the RF and switched-mode power supply (SMPS) are active. The STM32WB15CCU6 features 320 KB of flash memory and 48 KB of SRAM, with additional hardware support for real-time operations and a rich set of peripherals, including a 12-bit ADC and multiple communication interfaces. The device is suitable for applications requiring compliance with various radio frequency regulations, including ETSI and FCC standards. It also includes security features such as hardware encryption and a true random number generator, making it a robust choice for secure wireless communication projects.
