24C EEPROM PDF

Introduction. EEPROM, or Electrically Erasable Programmable Read-Only Memory, is a type of device that allows you to store small chunks of data and retrieve it. resistor to the same VCC power source as EEPROM, if MCU is powered by a different Figure 1: GIANTEC 24 series EEPROM recommended connections. General Description. The 24C02 / 24C04 provides / bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as.

Bi-directional pin for serial data transfer. Supply voltage; 5V up to 5.

The software will run indefinitely until it finds a flaw. For more details on different operations and addressing, refer interfacing 24C02 with Eepgom of theory but first let me explain why I decided to develop such project.

This data byte is to be written on or read by the microcontroller. If you need to ask me a question, suggest an enhancement deprom report a bug, please use the contact form below:. This last bit is 1 for write and 0 for read operation. Choosing Motor For Robots.

Similarly for read operation the device address to be sent is 0xA0 There are 32 x 8 words each of one byte. And on the next run write its invert: The data is read or written between the start and stop conditions on every transition of SCL from high to low. This flaw put the 12V from the power supply directly eepeom the 5V line causing a permanent damage to the uC ATmegaP. This high-density System-in-Package SiP integrates controller, power switches, and support components.

My idea is to write in each byte the following bits: And now the code: Cookies This site uses cookies: It has a 2Kbits of memory size arranged in 32 pages of 8 byte each. When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself.

Serial EEPROM AT24C02

Finally a stop condition is provided. The data is transferred and received serially through serial data SDA pin. The circuit is extremely simple. What is Web Browser.

This means that the data is retained even if the chip is not being powered. As homework you can try to change this code into a more effective and simpler one. Around April one of the Arduinos I own, a Nano 3. Interface GPS with Arduino.

Eeprrom device can be addressed serially by the software. These type of EEPROMs can be written more than 1 million times and behave like tiny hard drives which make them ideal for data and program storage.

Your e-mail double check your e-mail or I won’t be able to contact you. The second number is the random value which will be written into that byte. Skip to main content.

There are three address pins 24cc AT24C02 for selecting a particular chip. Next, the byte or page address is sent followed by the data byte. Choosing Battery for Robots. Vcc enables write protection. Now compile it, open the Serial Monitor and let it run for a while.

The first number represents the byte position which will be tested.
