It also has an oscillator utilizing an external crystal for timing back-up, clock/calendar registers, intelligent battery back-up switching, battery voltage monitor, brownout indicator, integrated trickle charger for super capacitor, single periodic or polled alarms, POR supervisory function, and up to 4 Event Detect with time stamp. There are 128 bytes of battery-backed user SRAM. The oscillator uses a 50/60 cycle sine wave input, backed by an external, low-cost, 32.768k Hz crystal. The real time clock tracks time with separate registers for hours, minutes, and...
