The STMicroelectronics STM32WLE5CCU6TR is an ultra-low-power wireless microcontroller combining a 32-bit Arm Cortex-M4 processor and an integrated Sub-GHz radio. The CPU operates at up to 48MHz, while the radio supports LoRa, (G)FSK, (G)MSK, and BPSK modulation, making the device suitable for LoRaWAN, proprietary Sub-GHz networks, and other LPWAN applications. ST currently lists the STM32WLE5CC as Active and in volume production.
The STM32WLE5CC integrates 256KB of Flash memory and 64KB of SRAM. Its radio covers a continuous 150MHz to 960MHz frequency range, with LoRa receive sensitivity down to -148dBm under specified conditions. The high-power transmitter path is programmable up to +22dBm, while a low-power output path supports up to +15dBm.
Integrated peripherals include a 12-bit ADC, 12-bit DAC, two low-power comparators, two USARTs, one LPUART, three I²C interfaces, and two SPI interfaces, with one SPI supporting I²S. The device also includes multiple general-purpose and low-power timers, two 7-channel DMA controllers, RTC, watchdogs, and up to 29 GPIOs on the 48-pin version.
Security functions include AES-256 hardware encryption, true random number generation, a public-key accelerator, CRC, and Flash/SRAM protection mechanisms. An integrated high-efficiency SMPS and multiple low-power operating modes help reduce power consumption in battery-powered wireless nodes.
For the exact STM32WLE5CCU6TR order code, the first C identifies the 48-pin version, the second C specifies 256KB Flash, U denotes the UFQFPN package, 6 identifies the -40°C to +85°C temperature grade, and TR denotes tape-and-reel packaging. The UFQFPN48 package measures 7 × 7mm, and the device operates from a 1.8V to 3.6V supply.
