Communication with EEPROM

Posted on August 24, 2004 at 04:44

Hi Can anybody help me in solving the following problem?

I have interfaced a serial EEPROM M24C08 from ST to I2C0 port of STR710F .

I have made E2 line of EEPROM =logic 1 and have Left E1, E0 pins unconnected.

I am transmitting 0xAC as my first address byte ( which includes the

device select code-1010 ,

chip enable E2-1

and as I am writing to Block2 A9=1;A8=0

R/W~=0). But the device is not responding?

The STR710F Hardware reference manual states the user to send one header byte ( 11110xx0) where in 1111 corresponds to the device select code of slave connected. I would like to know why the device select code is fixed to 1111 and how does eeprom ( device select code 1010) will understand this and respond to this?
