Serial EEPROM Interfacing_Microcontroller

[shabbirn]

Hi friends,

Is it possible for a microcontroller (8051 core) to interface a Serial EEPROM instead of Paralled EEPROM for CODE memory.
Pls let me know, if any techniques are there for this..

Thanks in advance...

Sir,
Thanks for your reply, I don't want to interface Serial EEPROM for data storage, but for code memory.
Suppose if I a limited on-chip ROM, and for having external EEPROM (CODE memory), is it possible to interface SERIAL EEPROM instead of parallel (to avoid using of address/data ports for memory).

You need add paralel RAM and copy that Serial EEPROM data to it. After copying is complete, jump/call it. Or just use IAP type microcontroller with the same steps with the first one. But if all of you did is aimed to update your firmware, using bootlaoder is better.
