General Description
The HT42B564-x device is a high performance USB
to UART bridge controller with fully integrated
USB and UART interface functions, designed for
applications that communicate with various types
of UART. The device includes a USB 2.0 full
speed compatible interface which is used for PC
communication. The device also includes a fully
integrated high speed oscillator which is used as clock
source for the USB and UART baud rate generator.
The baud rate generator can support up to 115200bps
of baud rate for the UART interface.
