Hello.
I'd like to integrate a batteries-operated RTC (real-time clock) module in my system, and to have it communicating with a 8051 Uc.
How such communication is performed? through SPI?
How much time does it work before you have to switch its batteries?
Could you please recommend on such RTC module?
I'm not sure what specifications I should be aware of when looking for such module.
Regards.
