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.

Around April one of the Arduinos I own, a Nano 3. Enough of theory but first let me explain why I decided to develop such project. The software will run indefinitely until it finds a flaw. This flaw put the 12V from the power supply directly into eepro 5V line causing a permanent damage to the uC ATmegaP.

24C02 | EEPROM AT24C02 | Datasheet – Pin Diagram & Description

This means that the data is retained even if the chip is not being powered. Virgin Galactic — Commercial Space Flight.

For more details on different operations and addressing, refer interfacing 24C02 with And now the code: Choosing Motor For Robots. As homework you can try to change this code into a more effective and simpler one. Skip to main content. 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 32 x 8 words each of one byte.


Now compile it, open the Serial Monitor and let it run for a while. Vcc enables write protection. This last bit is 1 for write and 0 for read operation. Finally a stop condition is provided.

This high-density System-in-Package SiP integrates controller, power switches, and support components. The second number is the random value which will be eperom into that byte. The device can be addressed serially by the software.

Serial EEPROM AT24C02

Interface SD Card with Arduino. It has a 2Kbits of memory size arranged in 32 pages of 8 byte each. Bi-directional pin for efprom data transfer. Similarly for read operation the device address to be sent is 0xA0 And on the next run write its invert: SPI Module of Arduino.

The circuit is extremely simple. My idea is to write in each byte the following bits: There are three address pins in AT24C02 for selecting a particular chip. Your e-mail double check your e-mail or I won’t be able to contact you. 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. If you need esprom ask me a question, suggest an enhancement or report a bug, please use the erprom form below:.

Supply voltage; 5V up to 5. Interface GPS with Arduino. Choosing Battery for Robots. The data is transferred and received serially through serial data SDA pin. Arduino based GPS receiver. The data is read or written between the start and stop conditions on every transition of SCL from high to low. Next, the byte or page address is sent followed by the data byte.

The first number represents the byte position which will be tested. Cookies This site uses cookies: This data byte is to be written on or read by the microcontroller. What is Web Browser.
