Main features

• The Low Power consumption configuration allows the RTC module to record timekeeping and system abnormalities on its own even when the main MCU is into sleep mode.
• Some products have a built-in temperature-compensated oscillator to guarantee and manage high-precision date and time information using only RTC module.
• AEC-Q100/200 compatible products are also available.
