What is the DS1302ZN+T&R used for?

It is used in embedded systems to maintain accurate time and date, even when the main system power is removed, thanks to its battery backup capability.

What are the key specifications of the DS1302?

It operates from 2V to 5.5V, features a 3-wire serial interface, includes trickle-charge circuitry, and operates between -40°C and +85°C.

What should engineers review before using the DS1302?

Ensure the 3-wire serial protocol is compatible with your host controller and verify the battery backup circuit design.

What should sourcing teams check before buying DS1302ZN+T&R?

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

What is the pinout of DS1302ZN+T&R?

Use the DS1302ZN+T&R datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about DS1302ZN+T&R pinout to locate pins, power rails, and interface signals before layout.
