3.0 Introduction
PL-2303HX provides a convenient solution for connecting an RS232-like full-duplex asynchronous
serial device to any Universal Serial Bus (USB) capable host. PL-2303HX highly compatible drivers
could simulate the traditional COM port on most operating systems allowing the existing applications
based on COM port to easily migrate and be made USB ready.
By taking advantage of USB bulk transfer mode, large data buffers, and automatic flow control,
PL-2303HX is capable of achieving higher throughput compared to traditional UART (Universal
Asynchronous Receiver Transmitter) ports. When real RS232 signaling is not required, baud rate
higher than 115200 bps could be used for even higher performance. The flexible baud rate generator of
PL-2303HX could be programmed to generate any rate between 75 bps and 6M bps.
PL-2303HX is exclusively designed for mobile and embedded solutions in mind, providing a small
footprint that could easily fit in to any connectors and handheld devices. With very small power
consumption in either operating or suspend mode, PL-2303HX is perfect for bus powered operation
with plenty of power left for the attached devices. Flexible signal level requirement on the RS232-like
serial port side also allows PL-2303HX to connect directly to any 3.3V~1.8V range devices.

6.0 USB Standard Descriptors
PL-2303HX supports one configuration with one interface and four endpoints. The descriptors are
basically stored in an internal Mask ROM. However, some fields could be optionally modified by
properly programmed external 2-wire serial EEPROM. The contents of all descriptors are shown in the
following sections.

Configuration Registers, DCR, of PL-2303HX). If all remote wakeup sources are disabled, the bmAttributes will be 80h.
Otherwise, A0h is returned to indicate that this device is Remote Wakeup capable.

(4) – The value of maximum power consumption can be configured initially by setting DCR on the external EEPROM. If it is set
to 1, the MaxPower byte will be FAh to indicate 500mA required from the USB host. Otherwise, it is 32h that indicates
100mA required.

6.7 String Descriptors
PL-2303HX supports four string descriptors:
Language ID
Manufacturer
Product
Serial Number
Except for Serial Number, the other three string descriptors are stored in the internal Mask ROM, i.e.
their contents are fixed. Serial Number is a special case. If the External EEPROM were not present, or
not properly programmed, then Serial Number would be hidden from the system. If the External
EEPROM is presented and properly programmed, then Serial Number will be read from the EEPROM.
The following tables demonstrate the current defined value for each descriptor:

28-pin SSOP (Lead-Free or Pb-Free)
Figure 11-1 Chip Part Number Information
Note: The chip datecode and version are found on the second line of the top chip marking:
Where: LF – Lead-Free
YY – last two digits of the year
WW – week of the year
3A – chip version
Example: “LF10123A” – means Lead-Free + year 2010 + week no. 12 + 3A chip version.
