S-3531A
REAL-TIME CLOCK
S-3531A is a CMOS real-time clock IC supporting an I
2C-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. The shipping form is either a die or an 8-pin SSOP ultra
compact package.
