This high-density System-in-Package SiP integrates controller, power switches, and support components. Interface Datasgeet Card with Arduino. There are three address pins in AT24C02 for selecting a particular chip. The theoretical basis of these devices is Avalanche hot-carrier injection.

Next, the byte or page address is sent followed by the data byte. You didn’t want it last time, but I saved it for you anyway. Interface GPS with Arduino.

It was also used on video game cartridges to save game progress and configurations, before the usage of external and internal flash memories. Archived from the original on 3 May By using this site, you agree to the Terms of Use and Privacy Policy.

In the above setup, I knew it of course, as I myself wrote it. Most devices have chip select and write protect pins. Microelectronic Engineering, Rochester Institute of Technology. Virgin Galactic — Commercial Space Flight.

Electronic Inventions and Discoveries: And eeeprom not initializing the variable “result” is indeed not quite! Products such as real-time clocksdigital potentiometersdigital temperature sensorsamong others, may have small amounts of EEPROM to store calibration information or other data that needs to be available in the event of power loss.

In Maysome important research result was disclosed by Fairchild and Siemens.

Reading/writing from/to 24c02 eeprom

It has a 2Kbits of memory size arranged in 32 pages of 8 byte each. EPROMs can’t be erased electrically and are programmed via hot carrier injection eeproom the floating gate. It hasn’t yetso you return your unitialised variable “result”, but the library kindly buffers the data from the I2C bus when it does arrive.

In this particular setup, at least. As is described in former section, old EEPROMs are based on Avalanche breakdown -based hot-carrier injection with high reverse breakdown voltage.

Serial EEPROM AT24C02

Erase is via an ultraviolet light source, although in practice many EPROMs are encapsulated in plastic that is opaque to UV light, making them “one-time programmable”. When data is datasbeet be read or write, first a start condition is created followed by device address, byte address and the data itself.

The data is read or written between the start and stop conditions on every transition of SCL from high to low. Reading the datasheet gave me the wrong impression that I could get away with being impatient. Retrieved from ” https: Many microcontrollers include both: Views Read Edit View history.

Bi-directional pin for serial data transfer. EEPROM still requires 2 transistors structure per bit to erase a dedicated byte in the memory, while flash memory dataheet 1 transistor per bit to erase a region of the memory. In the industry, there is a convention to reserve the term EEPROM to byte-wise erasable memories compared to block-wise erasable flash memories.
