The MAX31331 ultra-low power, real-time clock (RTC) is a time-keeping device that consumes nominal 65nA timekeeping current, extending battery life.

a backup supply pin (VBAT) and automatically switches over to the backup supply (VBAT) when the main supply (VCC) drops below the programmed threshold voltage and the backup supply (VBAT) voltage. Other features include two time-of-day alarms, interrupt outputs, programmable square-wave output, event detection input with timestamping, and a serial bus timeout mechanism. The 32-byte timestamp registers double as RAM storage. The device features a digital Schmitt trigger input (DIN) which can be u.
