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. Cookies This site uses cookies: The software will run indefinitely until it finds a flaw. The second number is the random value which will be written into eepfom byte. Similarly for read operation the device address to be sent is 0xA0 Skip to main content.

Choosing Battery for Robots. Enough of theory but first let me explain why I decided to develop such project.


Arduino based GPS receiver. And on the next run write its invert: There are 32 x 8 words each of one byte.

What is Web Browser. Now compile it, open the Serial Monitor and let it run for a while.

24C EEPROM Check –

There are three address pins in AT24C02 for selecting a particular chip. The first number represents the byte position which will be eepgom. And now the code: If you need to ask me a question, suggest an enhancement or report a bug, please use the contact eepeom below:.

Interface GPS with Arduino. The data is read or written between the start and stop conditions on every transition of SCL from high to low.

Serial EEPROM AT24C02

Vcc enables write protection. My idea is to write in each byte the following bits: This data byte is to be written on or read by the microcontroller. This flaw put the 12V from the power supply directly into the 5V line causing a permanent damage to the uC ATmegaP. Interface Edprom Card with Arduino.


This high-density System-in-Package SiP integrates controller, power switches, and support components. 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. 2c4 last bit is 1 for write and 0 for read operation. Bi-directional pin for serial data transfer.

As homework you can try to change this code into a more effective and simpler one. This means that the data is retained even if the chip is not being powered.

Choosing Motor For Robots.

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

SPI Module of Arduino. The circuit is extremely simple. It has a 2Kbits of memory size eepeom in 32 pages of 8 byte each. Virgin Galactic — Commercial Space Flight. The device can be addressed serially by the software.
