What are the key features of the DS1302Z?

It features a 3-wire serial interface, 12/24-hour time format, leap year compensation, and a programmable trickle charger for backup batteries.

What is the operating voltage range?

The device operates within a wide voltage range of 2.0V to 5.5V.

What should engineers consider during PCB design?

Engineers should place the 32.768kHz crystal as close as possible to the X1 and X2 pins and maintain a clean ground plane to prevent oscillator interference.

What should sourcing teams check before buying DS1302Z?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: low; readiness: easy.

What is the pinout of DS1302Z?

Use the DS1302Z datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about DS1302Z pinout to locate pins, power rails, and interface signals before layout.
