Overview

Rev.
1.
2 REAL-TIME CLOCK S-3511A S-3511A is a CMOS real-time clock IC, 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 three wires and has an interrupt/alarm feature, 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.
The shipping form is either a die or an 8-pin SSOP ultra compact package.
! 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 three wires • • 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 • St...
