描述 Description

The F81232 is a highly-integrated USB to UART bridge controller providing a simple solution for updating RS-232 design to USB using a minimum of components. A programmable generator is provided to select baud rate from 1200 to 115.2kbps.(1)In the USB interface function, The F81232 communicates with the host by full-speed USB interface (12Mb/s). It supports 4 suits endpoint, one control endpoint( endpoint zero) is for bus enumeration, one output endpoint is for UART transmit data and two input endpoint is transmit UART data and status to host. (1)In I2C interface function, The F81232 builds 256 bytes SRAM to save from I2C flash/ROM information for USB bus enumeration. The I2C flash/ROM contains IdVendor/ IdProduct/ BcdDevice/ Manufacturer string / IProduct string / iSerialNumber string information.(1)In the power function, The F81232 supports remote-wakeup function for USB interface, when PC system into S3 state. The F81232 receives UART data to asserted USB interface to wakeup PC system.(1)(1)
