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.
