CCS/TMS320F28388D: enthercat& requirements for the corresponding EEPROM

Susan Yang

Part Number: TMS320F28388D

Tool/software: Code Composer Studio

Dear team

Does the 28388d's built-in enthercat module have any requirements for the corresponding EEPROM model of the I2C interface?

In user's guide It shows that

"Size of the memory is configurable with a minimum of 1Kbit up to 4Mbit are supported depending on the ESC.

Refer to the ESI and EtherCAT documentation from ETG and Beckhoff for ESI EEPROM Layout and mandatory information."

Do we have any detail information?

Besides,could you show me why we CAT24C16(8-bit byte addressing) as ethercat eeprom on F28388D controlCARD?

Hello

You'll want to select a serial EEPROM with an I2C interface. The minimum size is 1Kbit and supports up to EEPROM of size 4Mbit.

If you want some more technical info on the EEPROM I2C interface, can look here.

Best regards

Chris

One helpful note is depending on the size of the EEPROM you may need to set a bit.(I forget the name of the bit off of the top of my head) The cut off point is below 16Kb or above.

Taken from the BECKHOFF spec.
