Note: As a system real-time time clock, there are two possible solutions:
-
The OMAP5910 internal solution (internal RTC and 32-kHz oscillator pads) is not a low-power solution, because
the OMAP5910 RTC power supply is not separate from the OMAP5910 core power supply.
-
The OMAP5910 external solution (external RTC and 32-kHz oscillators) is the recommended solution for low IDDQ.
