Design a Custom BoardAbout This Component
Low-power real-time clock and calendar IC with I2C interface tracking hours, minutes, seconds, day of week, date, month, and year through 2099 with automatic leap year correction. Features 32.768kHz crystal oscillator, battery backup switching, 2-byte SRAM, power-fail detection, and selectable frequency outputs. Typical applications include utility meters, HVAC systems, network equipment, set-top boxes, and industrial/medical/automotive devices.
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.
