This allows the chip time to complete the write operation, without this if you try to do sequential writes weird things might happen. With the address pins connected the hardware part of this tutorial is complete and every pin of the 24LC should be connected to either Vcc, GND or the Arduino.

Add to Watch list Watching.

Finally we have to pass along the byte we want to store. Next we have to send the address on the eeprom we want to write to. This excludes weekends and public holiday.

The next three bits A2,A1,A0 are the important bits that we can change so lets look at the simple table below to 244c64a what address the chip will have depending on what we set these pins to.

We need to send the MSB Most significant bits first so we have to shift our address to the right eight bits. The Write Protect pin allows you to protect the top bytes of memory from changes – if this pin is low 0V then all writes are allowed. Positive Voltage between 2. Please enter a valid postcode.

A brand-new, unused, unopened and undamaged item in original retail packaging where dafasheet is applicable. This means our 24LC chip gets the address and then which tells it to store the next byte in address location 20, For more information, please see the Atmel AT24C64 datasheet: Take a look at our Returning an 24c64x help page for more details. The first send function takes the eeaddress and shifts the bits to the right by eight which moves the higher end of the 16 bit address down to the lower eight bits.
