Introduction
●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 0.6” 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).
●Features
●The UM232H has the following features:
●• Based on the Single chip USB Hi-Speed FT232H device.
●• USB 2.0 Hi-Speed (480Mbits/Second) and Full Speed (12Mbits/Second) 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 RS485 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.
