STMICROELECTRONICS: ANTENNA-MATCHING RF INTEGRATED PASSIVE DEVICES FOR STM32WL MCUS

STMicroelectronics has released a broad selection of antenna-matching RF integrated passive devices for STM32WL MCUs.

ST’s STM32WL MCUs combine application-level processing and wireless communication for smart, connected devices, by integrating an Arm^® Cortex^®-M4 MCU with a sub-GHz long-range radio managed by a Cortex-M0+ core.

The RF IPDs, packaged as tiny chip-scale devices, connect the STM32WL MCU to its antenna and help maximize the RF performance. By integrating all the components on one die, they ensure consistent performance avoiding the process variations that affect conventional matching networks built with discrete components. They also simplify circuit design, save on bills of materials, and permit a smaller form factor, making them ideal for cost-sensitive and space-constrained IoT devices.

The nine RF IPD variants available let designers choose the optimum parameters according to the RF frequency range and power, MCU package type, and two- or four-layer PCB.

All devices are in production and offered in a 2.13mm x 1.83mm 8-bump wafer-level chip-scale package that has a profile below 630µm after reflow.
