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.

It has a Leap-Year compensation from up to for a value of This is a cheap module with the DS So the code has to detect that condition to prevent an extra clock pulse.

For more info pleae look at this Forum Post. The data in this ram will get lost if the Arduino is off, and the battery or supercap gets empty. The code below contains basic interface functions for the DS At this moment there is no official library for date and time functions for the Arduino.

That is also wrong. For the name of a month, this page contains many languages: That way the check for the 7th bit is not needed, since the line is always released. Board Setup and Configuration. Some schematics on the internet dataheet pull-up resistors on the three interface lines.


Arduino on other Chips. To prevent that, ds1032 DS has a buffer to store the clock data. The most used name is ds302 interface”. That would result in bad clock data.

The Year data of the DS is only two digits The page at maxim for the DS with all information and datasheet: Use it with Arduino 1. The three pins for the interface should avoid to use the internal pull-up resistors of the Arduino.

Sources for Electronic Parts. See the datasheet for full specifications and a datsheet. This circuit has pull-down resistors which are an extra, in many cases they are not needed.

The Year ‘0’ isand not or datasheeet The playground is a publicly-editable wiki about Arduino. The most used date and time functions for 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.


You are strongly advised to use a DSwhich is very reliable and accurate and needs d1s302 a battery to run the crystal is inside the DS I was noted that the code could be improved.

If a byte is read, the addres is written first. The standard date dz1302 time functions like: The Vcc1 is for a battery or a rechargable battery or a supercap. They often don’t work very well.

Other schematics use two 22pF with the crystal. Related Datasheett and Initiatives. That buffer can be read in a single communication session, called a “burst” mode. The DS can be easily connected to the Arduino.

A crystal of During reading, the clock could rollover. The chip has 31 bytes of ram.

Cheap modules with the DS and DS have often problems with the crystal and the voltage.
