DS chip is commonly used as DS RTC module which comes with a 32 kHz crystal and on-board battery backup all in a small SIP. Part Number: DS, Maunfacturer: Maxim, Part Family: DS, File type: PDF, Document: Datasheet – semiconductor. DS The DS trickle-charge timekeeping chip contains a real-time clock/ calendar and 31 bytes of static RAM. It communicates with a microprocessor via.

Arduino Playground – DS

The most used date and time functions for the Datashfet The most used name is “3-wire interface”. Other schematics use two 22pF with the crystal.

During reading, the clock could rollover. A crystal of Use it with Arduino 1. At this moment there is no official library for date and time functions for the Arduino. The Year ‘0’ isand not or Related Hardware and Initiatives.

This circuit has pull-down datzsheet which are an extra, in many cases they are not needed. Cheap modules with the DS and DS have often problems with the crystal and the voltage. Arduino on other Chips. That is also wrong. Sources for Electronic Parts.


You are strongly advised to use a DSwhich is very reliable and accurate and needs only a battery to run the crystal is inside the DS That way the check for the 7th bit is not needed, since the line is always released. The code below contains basic interface functions for the DS It has a Leap-Year compensation from up to for a value of Some schematics on the internet have pull-up resistors on the three interface lines.

This is a cheap module with the DS For more info pleae look at this Forum Post. The data in this ram will get lost if the Arduino is da1302, and the battery or supercap gets empty.

Datasheet «DS1302»

If a byte is read, the addres is written first. The playground is a publicly-editable wiki about Arduino.

See the datasheet for full specifications and a circuit. The DS can be easily connected to the Arduino. The last clock pulse of the address using the rising edge is also the first clock pulse of the data to read using the falling edge.


For the name of a month, this page contains many languages: The three dafasheet for the interface should avoid to use the internal pull-up resistors of the Arduino.

To prevent that, the DS has a buffer to store the clock data. The chip has 31 bytes of ram. The standard date and time functions like: That would result in bad clock data.

The Year data of the DS is only two digits I was noted that the code could dayasheet improved. So the code has to detect that condition to prevent an extra clock pulse. Board Setup and Configuration.

The Vcc1 is for a battery or a rechargable battery or a supercap.
