Introduction[edit | edit source]

This article describes the options available for the real-time clock (RTC) implementation on SBC Lynx.

i.MX6UL's native RTC (default option)[edit | edit source]

The default option is based on i.MX6UL's native RTC. The simplified block diagram of this solution is depicted in the following image.

When the system is powered off, on-board battery powers i.MX6UL's native RTC.

When the system is powered on, the battery is recharged.

This solution is quite simple and cheap. However, it TBD. In case a longer timekeeping operation time is required, it is possible to not populate the on-board battery and to connect a bigger one to the connector J56. For more information, please contact Sales department.

ST M41T83 (alternative option)[edit | edit source]

This option is based on [ST M41T83 http://www.st.com/en/clocks-and-timers/m41t83.html] RTC. The simplified block diagram of this solution is depicted in the following image.


This solution is more expensive but guarantees a longer timekeeping operation time, because M41T83 power consumption is very low. In any case, it is possible to not populate the on-board battery and to connect a bigger one to the connector J56 to achieve an even longer operation time.
