Hi,

It is possible to save date, which user insert by USART, in EEPROM in
order to it will be save even if microcontroller is off. If yes I will
be graceful for a sample code in C which show how to do it.

Thanks in Advance.

Yes,

Since a AT91SAM7S does not offer an internal Eeproms there is no general
"sample code in C" for this. Most external EEproms either offer an SPI
or TWI interface. Look into the Atmel AT91 software-package for examples
on using SPI and I2C/TWI. The EEprom's datasheet includes the commands
and timing-diagrams.
