Many microcontrollers include both: I speak for myself, not Arduino. What is Web Browser. In the industry, there is a convention to reserve the term EEPROM to byte-wise erasable memories compared to block-wise erasable flash memories. Most NOR datxsheet memory is a hybrid style—programming is through hot carrier injection and erase is through Fowler—Nordheim tunneling.

Serial EEPROM AT24C02

This page was last edited on 20 Octoberat Yes, I did read the datasheet, but it seems that I do not fully grasp some of the issues Japanese inventions Non-volatile memory Computer memory. EEPROM also E 2 PROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systemand other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed.

Reading the datasheet gave me the wrong impression that I could get away with being impatient.


This high-density System-in-Package SiP integrates controller, power switches, and support components. The electric field of the trapped electrons adds to the electrons in the floating gate, lowering the window between threshold voltages for zeros vs ones.

When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself. Interface SD Card with Arduino.

Electronic Inventions and Discoveries: As is described in 24cc02 section, old EEPROMs are based on Avalanche breakdown -based hot-carrier injection with high reverse breakdown voltage. EEPROM still requires 2 transistors structure per bit to erase a dedicated byte in the memory, while flash memory has 1 transistor per bit to erase a region of the memory.

Datzsheet was also used on video game cartridges to save game progress and configurations, before the usage of external and internal flash memories.

In early s, some studies, inventionsand development for electrically re-programmable dataasheet memories were performed by various companies and organizations. Bi-directional pin for serial data transfer.

Finally a stop condition is provided. Next time you call the I2C read routine, you give it an address, and again 24c002 say “have you got any data? 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. This data byte is to be written on or read by the microcontroller.

For more details on different operations and addressing, refer interfacing 24C02 with EEPROM memory is used to enable features in other types of products that are not strictly memory products. 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”.

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.

And me not initializing the variable “result” is indeed not quite!

EEPROM can be programmed and erased electrically using field electron emission more commonly known in the industry as “Fowler—Nordheim tunneling”. Archived copy as title Wikipedia articles with GND identifiers.

EPROMs can’t be erased electrically and are programmed via hot carrier injection onto the floating gate. Interface GPS with Arduino. The manufacturers usually specify the maximum number of rewrites being 1 million or more.
