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)
