Hi,

I am having FX2LP(56 Pin Package) USB Controller and I want to store Firmware in the External EEPROM so that FX2 will start reading from the Externally EEPROM.

But FX2LP (56 pin package) does not have a EA pin So, Whether FX2LP(56 pin package) supports External EEPROM interface or not?

Regards,

Aditya Upadhyay

Hi Aditya,

We can use I2C EEPROMs and communicate with them for 56 pin package. But you cannot use the external memories which need address, data, and control lines.

Please refer to section 5.3 in the EZ USB TRM: https://www.cypress.com/documentation/technical-reference-manuals/ez-usbr-technical-reference-manual 

Regards,

Mallika
