Introduction

The UM232H is a USB-to-serial/FIFO development module in the FTDI product range which utilizes the FT232H USB Hi-Speed (480Mb/s) single-port bridge chip to handle the USB signaling and protocols. The UM232H is ideal for development purposes to quickly prove functionality of adding USB to a target design. The UM232H is a module designed to plug into a standard 0.6" wide 28 pin DIP socket. The USB connection to a host system is via a mini-B USB connector. All components used, including the FT232H, are Pb-free (RoHS compliant). The FT232H is a single channel USB 2.0 Hi-Speed (480Mb/s) to Serial/FIFO IC. It can be configured in a variety of serial or parallel interfaces, such as UART, FIFO or FTDI’s MPSSE mode which can configure either of the following interfaces: JTAG, SPI and I²C. For MPSSE mode, there is also 14 bit-banging lines available along with the four interface lines. In addition to these, the FT232H supports a CPU-Style FIFO mode and a fast serial interface mode. It also introduces a half-duplex FT1248 interface that provides a flexible data communication and high performance interface between the FT232H device and external logic.
