STM32WLE5 wireless SoC with support for multiple RF modulation schemes
Support for industrial products with additional QFN48 package options


STMicroelectronics announced today that it has added a QFN48 package option to its STM32WLE5 wireless SoC portfolio, supporting a wider range of industrial wireless applications. Users can now achieve easy production and cost savings with the 7 x 7mm QFN48 package, which is suitable for two-layer boards.

Based on ST's STM32L4 ultra-low-power MCU technology, the STM32WLE5 integrates Semtech's SX126x sub-GHz wireless transceiver. Long-term availability is assured, backed by ST's 10-year industrial longevity commitment.

The STM32WLE5 supports multiple RF modulation schemes, including (G)FSK, (G)MSK, BPSK, and proprietary protocols used in various sub-GHz long-range protocols, including LoRa® spread-spectrum modulation. Users can choose commercial software such as LoRaWAN® and wM-Bus stacks provided by ST and authorized partners, or flexibly apply outsourced or self-developed protocol stacks.

Supporting dual low-power (14 dBm) and high-power (22 dBm) transmit modes, it delivers excellent linear performance from 150 MHz to 960 MHz, ensuring technical compatibility with RF regulations in all markets worldwide across the unlicensed frequency range below 1 GHz. Receiver sensitivity down to -148 dBm also helps maximize RF range. Using only a single crystal for the High-Speed External (HSE) clock and radio functions reduces bill-of-materials (BOM) costs.

The STM32WLE5 portfolio now includes devices in a 5×5mm BGA73 size, alongside the newly expanded QFN48 package. Three Flash memory capacities are available per package: 64/128/256KB, and all devices offer a high percentage of user-assignable GPIOs.

The STM32WLE5 SoC, including the STM32WLE5J BGA73 and STM32WLE5C QFN48 versions, is now in production. For pricing information and sample requests, please contact your local ST representative office.
