EEPROM for Cypress TetraHub USB hub controller

Question: What kind of EEPROM can Cypress TetraHub USB hub controller talk to?

 

Answer:

Cypress TetraHub USB hub controller can talk to SPI EEPROM that are double byte addressable only.

TetraHub uses the command format from the '040 parts. The TetraHub cannot talk to '080 EEPROM parts, as the read command format used for talking to '080 is not the same as '040.

The '010s and '020s uses the same command format as used to interface with the '040 and hence these can also be used to interface with the TetraHub.
