STMicroelectronics STM32WLE5 wireless SoC products combine LoRa® LPWAN and other power-efficient sub-1GHz radio communications capabilities with a low-power MCU in a single chip.

With its low power consumption and small footprint, the STM32WLE5 enables the production of energy-efficient, compact, and lightweight new products for fast-growing industrial and IoT markets.

The new 7mm x 7mm QFN48 package option is particularly well suited to a simple two-layer board design which further eases manufacturing and reduces BoM costs.

The world’s first LoRa-enabled SoC, the STM32WLE5 also supports other RF modulation schemes including (G)FSK, (G)MSK, and BPSK.
