... Overview The PL-2303 operates as a bridge between one USB port and one standard RS232 Serial port. The two large on-chip buffers accommodate data flow from two different buses. The USB bulk-type data is adopted for maximum data transfer. Automatic handshake is supported at the Serial port. With these, a much higher baud rate can be achieved compared to the legacy UART controller ...

... Supported Data Formats and Programmable Baud Rate Generator The PL2303 USB-to-RS232 bridge controller supports versatile data formats and has a programmable baud rate generator. The supported data formats are shown on Table 2. The programmable baud rate generator supports baud rates up to 1.2M bps as shown in Table 3.

... External EEPROM and Device Configuration PL-2303 allows storing the configuration data in an external EEPROM. After reset, the first two bytes of EEPROM are checked. If the value is 067Bh, the EEPROM is valid and the contents of the EEPROM are loaded as the chip’s default parameters. Otherwise, the chip’s default setting is used. The content of EEPROM is shown in Table 4 below ...
