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.
6.1 Device Descriptor
Table 6-1 Device Descriptor
Offset Field Size Value Description
0 bLength Byte 12H Size of this descriptor (in bytes)
1 bDescriptorType Byte 01H DEVICE descriptor type
2 bcdUSB Word 0110H USB Specification Release Number 1.1
4 bDeviceClass Byte 00H
5 bDeviceSubClass Byte 00H
6 bDeviceProtocol Byte 00H
7 bMaxPacketSize0 Byte 40H Maximum packet size for endpoint zero is 64
8 idVender Word 067BH Vender ID (1)
10 idProduct Word 2303H Product ID (1)
12 bcdDevice Word 0300H Device Release Number (1)
14 iManufacturer Byte 01H Manufacturer string descriptor index
15 iProduct Byte 02H Product name string descriptor index
16 iSerialNumber Byte 00H/03H Serial number string descriptor index (2)
17 bNumConfigurations Byte 01H One configuration.
Notes:
(1) – The Vender ID, Product ID, and Device Release Number could be replaced by the contents of external EEPROM.
(2) – The serial number string descriptor index could be defined by the contents of external EEPROM. If specified, the index will
be 3 instead of 0.
6.2 Configuration Descriptor
Table 6-2 Configuration Descriptor
Offset Field Size Value Description
0 bLength Byte 09h Size of this descriptor (in bytes)
1 bDescriptorType Byte 02h CONFIGURATION descriptor type
2 wTotalLength Word 0027h Total length of data returned for this
configuration.
4 bNumInterface Byte 01h One interface for this device.
5 bConfigurationValue Byte 01h
6 iConfiguration Byte 00h
7 bmAttributes Byte A0h/80h
Characteristic attributes (3)
8 MaxPower Byte 32h/FAh Maximum power consumption (4)
Notes:
(3) – The Remote Wakeup attribute (bit 5) depends on the settings of the Remote Wakeup Enable (Setting in the Device
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.

ds_pl2303HX_v15F.doc
(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:
6.7.1 String Descriptor 0 – Language ID
Table 6-7-1 String Descriptor – Language ID

Note:
The size of Serial Number is fixed in PL-2303HX design. It must be exactly 8 UNICODE characters (or 16 bytes). Note that in
USB Specification, this serial number must be unique for each device.
