Real Time Clock[edit | edit source]

This chapter describes the technical specifications and features for the RTC component on the ORCA module.

There is no Real Time Clock available on ORCA, instead a low power Real Time Counter is provided on iMX8MPlus SoC.

Description[edit | edit source]

The ORCA module uses a 32.768kHz dedicated crystal in order to obtain an accurate time base for the Real Time Counter.

The Real Time Counter is not available in power down mode but it operates in low power mode and allow to program a timer alarm interrupt.

Use an external RTC with battery backup functionality if data retention is required.
