S-3530A Datasheet | Seiko Instruments

DISCONTINUED PRODUCT Rev. 1.3_00 REAL-TIME CLOCK S-3530A is a CMOS real-time clock IC supporting an I2CBUS, 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 an interrupt/alarm 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. Features - Low power consumption: 0.7 µA typ. (VDD=3.0 V) - Wide area of operating voltage: 1.7 to 5.5 V - BCD input/output of year, month, day, day of a week, hour, minute and second - CPU interface via two wires...
