Overview

DISCONTINUED PRODUCT Rev.
1.
3_00 REAL-TIME CLOCK S-3530A 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 (I2C-BUS) • Auto calender till the year of 2,099 (automatic leap year arithmetic feature included) • Built-in power voltage detecting circuit • Built-in constant voltage circuit • Built-in flag generating circuit on power on/off • Built-in alarm interrupter (two systems) • Stead...
