S-3530A

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...
