I2C EEPROM

The I2C EEPROM interface implements a subset of the I2C Master Specification (Please refer to the

Philips Semiconductor Standard I2C-Bus Specification for details on I2C bus protocols). The device’s

I2C EEPROM interface is designed to attach to a single “dedicated” I2C EEPROM, and it conforms to

the Standard-mode I2C Specification (100 kbps transfer rate and 7-bit addressing) for protocol and

electrical compatibility.

Note: Extensions to the I2C Specification are not supported. The device acts as the master and

generates the serial clock SCL, controls the bus access (determines which device acts as the

transmitter and which device acts as the receiver), and generates the START and STOP

conditions.

NVSTORE_SIG

This signature is used to verify the validity of the data in the first 256 bytes of

the configuration area. The signature must be set to ‘ATA2’ for

USB4640/USB4640i.

CLUN0_ID_STR

If the device to LUN mapping bytes have configured this LUN to be a combo

LUN, then these strings will be used to identify the LUN rather than the

device identifier strings.

NVSTORE_SIG2

This signature is used to verify the validity of the data in the upper 256 bytes

if a 512 byte EEPROM is used, otherwise this bank is a read-only configuration

area. The signature must be set to 'ecf1'.
