1.1    Function description

The CS32G020 Series are USB Type-C controllers launched by CHIPSEA, supporting USB Type-C and PD3.0 and applicable to fields such as AC adapter cellphone chargers, power banks, car adapters, HUB, etc. CS32G020 has a built-in ARM® Cortex™-M0 core with the max. clock rate of 48 MHz, making it competent for a wide range of industrial control applications and occasions requiring high CPU performance. It is also integrated with 64K-byte program flash, configurable-size data flash (shared with program flash), 4K-byte LDROM and 8K-byte SRAM. CS32G020 package includes QFN24 and QFN32.
