Design a Custom BoardAbout This Component
Real-time clock/calendar IC with integrated 31-byte battery-backed RAM and simple 3-wire serial interface. Tracks seconds through year with automatic leap-year compensation, operates from 2.0V to 5.5V, and consumes less than 300nA in backup mode. Industrial temperature range (-40°C to +85°C) suitable for embedded systems, data logging, and timekeeping applications requiring minimal power consumption.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
