6.3.3 Data Structure of EEPROM Content
The EEPROM is organized as following:
Address
Content
Note
1:0
Check Word – 0x067B (Predefined constant)
3:2
Vendor ID (idVendor field of Device Descriptor)
5:4
Product ID (idProduct field of Device Descriptor)
7:6
Device Release Number (bdcDevice field of Device Descriptor)
8
Attributes (bmAttributes field of Configuration Descriptor)
9
Max Power (MaxPower field of Configuration Descriptor)
15:10
Reserved for future use. Must be “0”
255:16
String Descriptor Table
The String Descriptor table is a linked data structure that holds all string descriptors recognized by this
chip in the order of its index. The first entry, String 0, represents the Language ID, as defined by the
USB specification. The second entry, String 1, is the Manufacturer Descriptor, as defined by the
Device Descriptor of PL-2507. The third and forth entries, String 2 and 3, are the Product Descriptor
and Serial Number, respective, also defined by the Device Descriptor. The user has the option to
define String 4, 5, and 6 for their own private use. Each of the these String Descriptor Entries is of the
following data structure:
Offset
Field
Size
Value
Note
0
bLength
1
Length of the string plus 2, i.e. (N + 2).
1
bDescriptorType
1
03h – STRING Descriptor type.
2
bString
N
UNICODE encoded string.
The last entry of this table must have bLength of 0 to indicate the end of this table. If the host tries to
access to the string descriptor beyond the last one, a zero-length data will be returned. The following
table shows one example of valid EEPROM contents.
