In addition to the small-capacity memory chip EEPROM and power device SJ-MOSFET, the company's self-developed chips, the company's first Cortex-M0+ core (32-bit) microcontroller product CW32F030 launched on October 14, 2021. It is the first M0+ MCU product of the CW32F series independently developed by the company.
