About this product
DS1302Z is a real-time clock IC that counts seconds, minutes, hours, date, month, day and year, with leap-year compensation up to 2100. It includes 31 bytes of battery-backed RAM and communicates with a microcontroller over a simple 3-wire serial interface. It suits data loggers and clocks that must keep time when the main supply is off.

Frequently asked questions
What is the price of DS1302Z Trickle-Charge Real-Time Clock IC, SOIC-8 in Egypt?
DS1302Z Trickle-Charge Real-Time Clock IC, SOIC-8 currently costs 17.1 EGP in Egypt.
Where can I buy DS1302Z Trickle-Charge Real-Time Clock IC, SOIC-8 in Egypt?
DS1302Z Trickle-Charge Real-Time Clock IC, SOIC-8 is available from UGE. Compare the offers above to find the best price.
How do I connect the DS1302Z to an Arduino?
Connect VCC to 5V or 3.3V within the supply range, GND to GND, and the three control lines CE, I/O and SCLK to digital pins. The chip also needs a 32.768 kHz crystal across X1 and X2, and a backup battery on the VCC1 pin keeps the time running when the main supply is off.
Can it be used with 5V logic?
Yes. The datasheet lists TTL compatibility at VCC = 5V, so it works with 5V microcontrollers. The Z suffix denotes the 8-pin SO package, which is a surface-mount part, so use the DIP version on breadboards.
