[miss_monica]

hello everybody
i just wanted to ask you whether i can interface a 93c66 eeprom chip with an 8051 ,is it possible to store data in the eeprom which the 8051 sends to it is there some page which can help me on how to store data in the eeprom

Re: eeprom

You can interface 8051 with serial eeprom.
You must read the pdf of eeprom memory.
Here is a link with an example:

Good luck

Try:

"EEPROM routines for WORD access to a 93c66 from 8051 core MPU"

Re: eeprom

Re: eeprom

Atmel has app notes on both kinds of eeproms 24LCXX and 93CXX types. although the code ans schematics are for a AT89C2051 but it will work the same for a 89C52.

You should study about I2C bus, its working and other details.
if you need more help mail me i will send you a I2C tutorial

Re: eeprom

I have my own library for interfacing (Read, Write) 8051 family to 24C16 EEPROM in C language. If u r interrested, i can send it to u. Please PM me if you need so.
