Design a Custom BoardAbout This Component
Low-power CMOS real-time clock with integrated calendar, optimized for minimal power consumption. Features I2C-bus interface (400 kbit/s max), programmable clock output, interrupt output, and voltage-low detector. Ideal for battery-powered embedded systems requiring accurate timekeeping with minimal current draw.
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.
