REAL-TIME CLOCK

S-3531A

S-3531A is a CMOS real-time clock IC supporting an I C-

BUS, which is designed to transfer or set each data of a

clock and calender as requested by a CPU. It provides

connection with a CPU via two wires and has two systems

of interrupt/alarm and clock output features, allowing the

alleviation of software treatment on the side of a host.

It also works on lower power with the oscillating circuit

operated at a constant voltage.
