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.

Next, the byte or page address is sent followed by the data byte. Supply voltage; 5V up to 5. The first number represents the byte position which will be tested.

Around April one of the Arduinos I feprom, a Nano 3. And on the next run write its invert: Arduino based GPS receiver. Interface SD Card with Arduino. The second number is the random value which will be written into that byte. Eeprrom device can be addressed serially by the software. This last bit is 1 for write and 0 for read operation. Similarly for read operation the device address to be sent is 0xA0 This means that the data is retained even if the chip is not being powered.


Now compile it, open the Serial Monitor and let it run for a while. For more details on different operations and addressing, refer interfacing 24C02 with Interface GPS with Arduino.

What is Web Browser. The data is transferred and received serially through serial data SDA pin.

This flaw put the 12V from the power supply directly into the 5V line causing a permanent damage to the uC ATmegaP. It has a 2Kbits of memory size arranged in 32 pages of 8 byte each.

Serial EEPROM AT24C02

This high-density System-in-Package SiP integrates controller, power switches, and support components. Virgin Galactic — Commercial Space Flight. If you need to ask me a question, suggest an enhancement or report a bug, please use the contact form below:.

Finally a stop condition is provided. Enough of theory but first let me explain why I decided to develop such project. Vcc enables write eeporm. There are 32 x 8 words each of one byte.

As homework you can try to change this code into a more effective and simpler one. And now the code: SPI Module of Arduino.

This data byte is to be written on or read by the microcontroller. My idea is to write in each byte the following bits: Cookies This site uses cookies: The software will run indefinitely until it finds a flaw.

24C EEPROM Check –

The data is read or written between the start and stop conditions on every transition of SCL from high 244c low. 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. The circuit is extremely simple.

When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself. There are three feprom pins in AT24C02 for selecting a particular chip.

Bi-directional pin for serial data transfer. Choosing Battery for Robots.
