Product overview
Description
The STSW-70WRXWLC firmware runs on the STM32F072CB of the STDES-70WRXWLC reference design.
The firmware controls the STWLC98 SoC to implement a Qi v1.2.4 and Qi v1.3-compliant wireless charging receiver. Once working with the ST solution-based wireless charging transmitter, it supports up to 70 W in the receiver output based on the ST super charging (STSC) protocol.
The firmware is the basic reference for evaluation. Contact ST sales and distributors the get the updated firmware for various applications.
