UCD3138064: 064 reference code of i2c eeprom

Jack Tan80

Part Number: UCD3138064

Hi UCD expert,

I'd like to use 064 device, and want to update the firmware via external i2c eeprom. First, I'd like to write all the flash data to eeprom, then copy all eeprom data to pflash. I remeber ti has reference code of i2c eeprom, can you please help me know how can I get that code?

Hi Jack, We don't really have a full reference code. We do have a description of how to write and read an EEPROM in the UCD3138064 programmer's manual, however. It is at https://www.ti.com/lit/ug/sluuad8b/sluuad8b.pdf. It's not that difficult to use an EEPROM with I2C, although there are variations between EEPROMs, so there's not really a way to write a generic code.
