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 to 12M 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.

PL-2303HX (Rev D) Product Datasheet - 14 - Document Version 1.1 Revised Date: April 16, 2007 ds_pl2303HXD_v1.1.doc 6.0 USB Standard Descriptors PL-2303HX supports one configuration with one interface and four endpoints. The descriptors are basically stored in an internal hardware ROM. However, some fields could be optionally modified by properly programmed on-chip OTPROM. The contents of all descriptors are shown in the following sections and the format of OTPROM would be given in later chapter. 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 4 bDeviceClass Byte 00h 5 bDeviceSubClass Byte 00h 6 bDeviceProtocol Byte 00h 7 bMaxPacketSize0 Byte 40h 8 idVender Word 067Bh Vender ID (1) 10 idProduct Word 2303h Product ID (1) 12 bcdDevice Word 0400h 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 17 bNumConfigurations Byte 01h USB Specification Release Number 1.1 Maximum packet size for endpoint zero is 64 Serial number string descriptor index (2) One configuration. Notes: (1) – The Vender ID, Product ID, and Device Release Number could be replaced by the contents of the on-chip OTPROM. (2) – The serial number string descriptor index could be defined by the contents of the on-chip OTPROM. 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 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) One interface for this device. Notes: (3) – The Remote Wakeup attribute (bit 5) depends on the settings of the Remote Wakeup Enable (bit 0 to 4 of Device PL-2303HX (Rev D) Product Datasheet - 15 - Document Version 1.1 Revised Date: April 16, 2007 ds_pl2303HXD_v1.1.doc Configuration Register 2). 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 depends on the LD_MODE (bit 5 of Device Configuration Register 2) parameter. If it is set to 1, the MaxPower byte will be FAh for it requires 500mA from the system. Otherwise, it is 32h that indicates 100mA required. 6.3 Interface Descriptor Table 6-3 Interface Descriptor Offset Field Size Value Description 0 BLength Byte 09h Size of this descriptor (in bytes) 1 BDescriptorType Byte 04h INTERFACE descriptor type 2 BInterfaceNumber Byte 00h One interface only 3 BAlternateSetting Byte 00h No alternate interface 4 BNumEndpoints Byte 03h Three endpoints (excluding control endpoint) 5 BInterfaceClass Byte FFh Vendor Specific Class 6 BInterfaceSubClass Byte 00h 7 BInterfaceProtocol Byte 00h 8 IInterface Byte 00h 6.4 Endpoint 1 Descriptor: Interrupt Input Endpoint Table 7-4 Endpoint1 Descriptor Offset Field Size Value Description 0 bLength Byte 07h Size of this descriptor (in bytes) 1 bDescriptorType Byte 05h ENDPOINT descriptor type 2 bEndpointAddress Byte 81h Input endpoint 3 bmAttributes Byte 03h Transfer type is INTERRUPT 4 wMaxPacketSize Word 000Ah 6 bInterval Byte 01h 6.5 Ten Bytes Polling on every 1 ms interval Endpoint 2 Descriptor: Bulk Data Output endpoint Table 6-5 Endpoint2 Descriptor Offset Field Size Value Description 0 bLength Byte 07h Size of this descriptor (in bytes) 1 bDescriptorType Byte 05h ENDPOINT descriptor type 2 bEndpointAddress Byte 02h Output endpoint 3 bmAttributes Byte 02h Transfer type is BULK 4 wMaxPacketSize Word 0040h 6 bInterval Byte 00h PL-2303HX (Rev D) Product Datasheet 64 bytes Ignored field - 16 - Document Version 1.1 Revised Date: April 16, 2007 ds_pl2303HXD_v1.1.doc 6.6 Endpoint 3 Descriptor: Bulk Data Input endpoint Table 6-6 Endpoint3 Descriptor Offset Field Size Value Description 0 bLength Byte 07h Size of this descriptor (in bytes) 1 bDescriptorType Byte 05h ENDPOINT descriptor type 2 bEndpointAddress Byte 83h Input endpoint 3 bmAttributes Byte 02h Transfer type is BULK 4 wMaxPacketSize Word 0040h 6 bInterval Byte 00h 6.7 64 bytes Ignored field String Descriptors PL-2303HX supports four string descriptors: ¾ Language ID ¾ Manufacturer ¾ Product ¾ Serial Number Except for Serial Number, the other three string descriptors are stored in the internal Mask ROM, i.e. their contents are fixed. The Serial Number is a special case. If the on-chip OTPROM is not properly programmed, then the Serial Number would be hidden from the system. If the on-chip OTPROM is properly programmed, then the Serial Number will be read from the on-chip OTPROM. The following tables demonstrate the current defined value for each descriptor: 6.7.1 String Descriptor 0 – Language ID Table 6-7a String Descriptor – Language ID Offset Field Size Value Description 0 bLength Byte 04h Size of this descriptor (in bytes) 1 bDescriptorType Byte 03h STRING descriptor type 2 bLANGID[0] Word 0409h English (United States) 6.7.2 String Descriptor 1 – Manufacturer Table 6-7b String Descriptor – Manufacturer Offset Field Size Value Description 0 BLength Byte 32h Size of this descriptor (in bytes) 1 bDescriptorType Byte 03h STRING descriptor type 2 bSTRING ⎯ ⇒ PL-2303HX (Rev D) Product Datasheet “Prolific Technology Inc.” in UNICODE - 17 - Document Version 1.1 Revised Date: April 16, 2007 ds_pl2303HXD_v1.1.doc 6.7.3 String Descriptor 2 - Product Table 6-7c String Descriptor – Product Offset Field Size Value Description 0 Blength Byte 30h Size of this descriptor (in bytes) 1 bDescriptorType Byte 03h STRING descriptor type 2 bSTRING ⎯ ⇒ “USB-Serial Controller C” in UNICODE 6.7.4 String Descriptor 3 – Serial Number Table 6-7d String Descriptor – Serial Number Offset Field Size Value Description 0 bLength Byte 12h Size of this descriptor (in bytes) 1 bDescriptorType Byte 03h STRING descriptor type 2 bSTRING ⎯ ⇒ “X7X6X5X4X3X2X1X0” in UNICODE Note: The size of Serial Number is fixed in PL-2303HX design.
