... 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 ...

... 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 ...
