Description

S-3531A is a CMOS real-time clock IC supporting an I2C-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. S-3531A also works on lower power with the oscillating circuit operated at a constant voltage. Its package uses an extremely small and thin type of eight-pin SSOP.
