Real Time ClockEdit
This chapter describes the technical specifications and features for the RTC component on the MITO 8M Mini/Nano module.
The Real Time Clock available on MITO 8M Mini/Nano is based on iMX8M Mini/Nano SoC.
FeaturesEdit
The MITO 8M Mini/Nano module uses a 32.768kHz dedicated crystal in order to obtain an accurate time base for the RTC.
Important note for RTC during power-offEdit
The Real Time Clock is kept operative through the PMIC_LICELL pin (J.14): the LICELL pin provides for a connection of a coin cell backup battery or a “super” capacitor.
A small capacitor should be placed from LICELL to ground under all circumstances.
For more information about PMIC RTC functionality, please refer to the PF8121 datasheet.
