Hi there - is it possible to use a memory module on the 12c address and a i2c address.


It is for an alarm clock and plan to use the DS3231 AT24C32 IIC Module Precision RTC Real Time Clock Memory 2020 does this have any extra memory ??

many thanks

Hello sthomas229
How are you?
Your question:

My answer:
Check the datasheet and run a tutorial of a.m. hardware.

I'm not sure I understand your question.

The RTC module you describe contains both an RTC (the DS3231) and an EEPROM (the AT24C32). Both of these devices are accessible on the I2C bus. Each device has its own address.

The EEPROM will give you 4Kbytes of non volatile memory.

Thanks for the help, sometimes one needs a nudge in seeing thinks the rigth way up

1.  In the following figure (Fig-1), you can see the I2C addresses for both RTC and EEPROM.
