Note
: More than 0X100 bytes of configuration are shown for example only. The AT2LP only supports addresses up to 0xFF.
Programming the EEPROM
There are three methods of programming the EEPROM:
Stand-alone EEPROM programmer
Vendor-specific USB commands, listed in
Table 12
In-system programming (for example, bed-of-nails tester)
Any vendor-specific USB write request to the Serial ROM device configuration space simultaneously update internal configuration
register values as well. If the I
2
C device is programmed without vendor specific USB commands, the AT2LP must be synchro-
nously reset (toggle RESET#) before configuration data is reloaded.
The AT2LP supports a subset of the ’slow mode’ specification (100 KHz) required for 24LCXXB EEPROM family device support.
Features such as ’Multi-Master,’ ’Clock Synchronization’ (the SCL pin is output only), ’10-bit addressing,’ and ’CBUS device
support’ are not supported. Vendor-specific USB commands allow the AT2LP to address up to 256 bytes of EEPROM data.
LOAD_CONFIG_DATA
This request enables writes to the AT2LP’s configuration data space. The wIndex field specifies the starting address and the
wLength field denotes the data length in bytes.
