UM232H-B Datasheet 1.2 D oc ument Reference N o.: FT _000721 C learance N o.: FT DI# 320 Future Technology Devices International Ltd Datasheet UM232H-B USB to Serial/Parallel Break-Out Module UM232H-B is a multiple-interface Hi-Speed USB to UART, 245 FIFO, FT1248, I2 C, SPI and GPIO break-out module. 1 Introduction 1.1 The UM232H-B is a development module for FTDI’s FT232H Hi-Speed to Serial/Parallel interface converter. This single interface channel IC can be configured to transfer data over the following interfaces UART, 245 FIFO, FT1248, I2C, SPI and GPIO. This hardware is a breakout board that converts HiSpeed USB2.0 to a serial/parallel interface and connects the signals to a 2.00mm pitch 18pin female receptacle. No USB connector is used, instead this modules plugs directly into the USB host connector and the pads of the PCB makes electrical contact with the electrical contacts of the host USB connector. For detail on datasheet. FT232H, refer to the FT232H Features All signals on these modules operate at +3.3V voltage levels, however all I/Os are 5V tolerant.
