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.

Key Features
