The FT230XS is a compact USB to a basic serial UART interface device which simplifies USB implementations in a small optimised package, with minimum UART signals and reduces external component count by fully integrating an MTP memory, and an integrated clock circuit which requires no external crystal. It has been designed to operate efficiently with USB host controllers by using as little bandwidth as possible when compared to the total USB bandwidth available.
