Real Time Clock[edit | edit source]

This chapter describes the technical specifications and features for the RTC component on the MITO 8M module.

The Real Time Clock available on MITO 8M is based on iMX8M SoC.

Features[edit | edit source]

The MITO 8M module uses a 32.768kHz dedicated crystal in order to obtain an accurate time base for the RTC.

Important note for RTC during power-off[edit | edit source]

On the MITO 8M module the SNVS voltage rails are obtained by the main supply of the SOM.

For this reason, there is no possibility to keep operative the CPU RTC when the SOM is not connected to the 3.3VIN power rail.

Use an external RTC with battery backup functionality if required.
