STM32WL55CCU6 概述
A wireless MCU is a microcontroller that integrates a radio transceiver on the same chip, enabling wireless communication without external RF components. The STM32WL55CCU6 belongs to the STM32WL series, which is part of the broader STM32 family of 32-bit microcontrollers. This SoC combines the processing power of an Arm Cortex-M4 core with the energy efficiency of a Cortex-M0+ core, allowing for flexible task partitioning and low-power operation.
Key features include a maximum CPU frequency of 48 MHz for both cores, a sub-GHz radio with sensitivity down to -137 dBm (LoRa), and support for LoRaWAN and Sigfox protocols. The device also includes a rich set of peripherals such as 12-bit ADC, DAC, comparators, timers, SPI, I2C, USART, and a random number generator. The integrated radio eliminates the need for an external transceiver, reducing BOM cost and PCB area.
The STM32WL55CCU6 is built on ST's low-power process technology, offering multiple low-power modes including Sleep, Stop, and Standby, with current consumption as low as 1.62 uA in Standby mode with RTC. The dual-core architecture allows the Cortex-M0+ to handle radio communication while the Cortex-M4 runs application code, optimizing power and performance.

设计说明
For optimal radio performance, match the antenna impedance to 50 ohms and place the antenna away from noisy digital traces. Use a ground plane on the PCB and ensure proper decoupling of the RF supply pins. Refer to ST's application note AN5457 for detailed RF layout guidelines.
Decouple the VDD and VDDA pins with 100 nF ceramic capacitors placed as close as possible to the pins. Use a 4.7 uF bulk capacitor on the main supply. For battery-powered applications, consider using the low-power modes to extend battery life.
The UFQFPN-48 package has a thermal resistance of approximately 40 C/W (theta_JA). For high-power applications, ensure adequate copper area on the PCB to dissipate heat. The device's maximum junction temperature is 125C, so calculate power dissipation to avoid exceeding this limit.
