EEPROM
TCM330 relies on an external EEPROM for storage of frequently changing parameters such
as configuration and status information as well as link tables.
The recommended EEPROM is Microchip 24AA08.
An I2C interface to the EEPROM is implemented in TCM 330 providing SCL and SDA inter-
face signals. External 1k pull up resistors to VDD (positive supply voltage) are required for
correct operation.
The illustration below shows the recommended connection between TCM 330 and the ex-
ternal EEPROM.
