Chengdu Silent Smart Technology Co., Ltd as STMicroelectronics China eco-partner with rich experience in module development, was the first one to release the STM32WL33-based wireless digital transmission module - WS8561DLS in September 2023.

The WS8561DLS is developed using STM32WL33, ST's latest SoC chip that supports GFSK debugging wireless communication protocols. The STM32WL33 integrates a general-purpose microcontroller and an RF unit on a single chiwhich includes an RF transceiver, a modem, and a 64MHz mains frequency, 32-bit MCU utilizing the Arm Cortex M0+ architecture, with 256kB of Flash capacity and an SRAM. The WS8561DLS has a Flash capacity of 256kB and an SRAM capacity of 32kB, which provides a longer transmission distance, faster speed, lower power consumption and smaller size.

WS8561DLS supports fixed-point transmission, transparent transmission, wireless wake-up, wireless relay and other functions. Its high-performance MCU makes a substantial improvement in function and efficiency. The internal data processing adopts 3-level cache, which greatly increases the stability and real-time data
