UM232H USB to Serial UART Development Module, FTDI Chip
The UM232H is a USB-to-serial/FIFO development module in the FTDI product range which utilises 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 0.6in wide 28-pin DIP socket. The USB connection to a host system is via a mini-B USB connector.
USB 2.0 Hi-Speed (480Mbits/s) and Full Speed (12Mbits/s) compatible Entire USB protocol handled on the chip – No USB-specific firmware programming required Small USB Type B connector common on many commercial devices USB bus or self-powered options Asynchronous UART transfer data rate up to 12Mbaud UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity Fully assisted hardware or X-On / X-Off software handshaking Auto-transmit buffer control for RS-485 applications Supports a half duplex FT1248 interface with a bi-directional data bus (1, 2, 4 or 8 bits wide) Synchronous Serial (MPSSE) data rates of up to 30Mbps on JTAG, SPI and I²C Support for USB suspend and resume UHCI / OHCI / EHCI host controller compatible FTDI’s royalty-free VCP and D2XX drivers eliminate the requirement for USB driver development in most cases +2.97 to +5.25V single-supply operation
