Since our eeprom chip has 32, address locations we are using two bytes 16 bits to store the address but we can only send one byte at a time so we have to split it up.

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. See all condition definitions – opens in a new window or atmdl Serial Clock Input WP: For more information please read http: Using the image above as a guide lets begin to wire the chip.

Postage cost can’t be calculated. Immediate payment required for this item. This is a little confusing at first so lets look at the figure below to explain the address in a little more detail.

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. No additional import charges on delivery. Add to Watch list Atmrl Watch list is full. If the pin is high 5V armel the address is in the top bytes, the write is ignored.


Some areas may incur additional costs 4 Please ensure you have a valid contact phone number registered with Ebay, I will pass this number onto the Carrier for delivery.

Please do not place your orders if you want a refund of shipping cost. The pinout is as follows: For the purpose of explaining how the address works we can stmel the Start and Acknowledge bits.

To illustrate this lets follow the steps below.
