Does the code given for EEPROM connected with CY7C65620 and CY7C65630 works with CY7C65640A?

Question: Does the code given for EEPROM connected with CY7C65620 and CY7C65630 works with CY7C65640A?

 

Answer:

No, the hub part CY7C65620 and CY7C65630 can work with D0, D2 and D4 load but device CY7C65640A can work only with D0 and D2 load. Also the format of D2 load of the devices is not same with the format of D2 load of CY7C65640A. So, in order to make the EEPROM contents of CY7C65620 and CY7C65630 part to work with CY7C65640A the bytes needs to be jumbled up, for example the number of active ports in D2 load of CY7C65640A is at byte number 5 but in CY7C65620 and CY7C65630 part it is byte number 8. So, the device needs to be configured according to their Load Descriptor.
