EEPROM Organization
The contents of the recommended 256-byte (2048-bit) I
EEPROM are arranged as follows. In
labeled ‘Required Contents’ contains the values that must be
used for proper operation of the AT2LP. The column labeled
‘Variable Contents’ contains suggested entries and values that
may vary (such as string lengths) according to the EEPROM
data. Some values, such as the Vendor ID, Product ID and
device serial number, must be customized to meet USB
compliance. The ‘AT2LP Blaster’ tool in the CY4615C kit can be
used to edit and program these values into an AT2LP-based
product (refer to
Document 001-05809 Rev. *B
Figure
11). The ‘AT2LP Primer’ tool can be used

C
to program AT2LP-based products in a manufacturing
environment and provides for serial number randomization. See
“Board Manufacturing Test Mode”
to use vendor-specific ATAPI commands to read and program
the EEPROM.
The address pins on the serial EEPROM must be set such that
the EEPROM is at physical address 2 (A0 = 0, A1 = 1, A2 = 0)
or address 4 (A0 = 0, A1 = 0, A2 = 1) for EEPROM devices that
are internally byte-addressed memories. It is recommended that
the address pins be set this way even on EEPROMs that may
indicate that the address pins are internal no-connects.
