iMX8M mini + PCA9450

[giacomobiancala]

Hi,

I am developing custom board based on iMX8M mini + PCA9450.

Is it possible to use internal RTC with backup battery? I suppose there is no possibility on PCA9450.

Is it necessary to use external RTC I2C IC?

Thanks,

Giacomo

Hi Giacomo

I believe you are right, as PCA9450 has not separate LICELL input as for example

PF4210.

Best regards
igor
