Problem using I2C for reading EEPROM 24LC515

2005-11-16 by Marcio Zaquela

Hi guys,

I´m having some problems reading EEPROM 24LC515 using I2C interface.

I can read addresses 0x0000 to 0x7FFF (BLOCK=0) but I can´t read addresses 0x8000 to 0xFFFF (BLOCK=1) of this memory.

The CONTROL BYTE for accessing BLOCK 0 is 0xA0 and for accessing BLOCK 1 is 0xA8. 

When I send 0xA8 I don´t receive any acknowledge bit from the memory (I receive the ACK when I send 0xA0).

Does anyone had any similar problem and can help me ?

Thanks,
Marcio
