What is Web Browser. There are three address pins in AT24C02 for selecting a particular chip. The manufacturers usually guarantee data eepprom of 10 years or more. Vcc enables write protection.

Bi-directional pin for serial data transfer. Yes, I did read the datasheet, but it seems that I do not fully dafasheet some of the issues The data is read or written between the start and stop conditions on every transition of SCL from high to low.

The manufacturers usually specify the maximum number of rewrites being 1 million or more. I corrected my code, recompiled, uploaded, tried Choosing Motor For Robots.

Serial EEPROM AT24C02

When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself. Views Read Edit View history. Most NOR flash memory is a hybrid style—programming is through hot carrier injection and erase is through Fowler—Nordheim tunneling.


This data byte is to be written on or read by the microcontroller. It was also used on video game cartridges to save game progress and configurations, before the usage of external and internal flash memories.

Japanese inventions Non-volatile memory Computer memory.

Next, the byte or page address is sent followed by the data byte. But each FLOTOX structure is in conjunction with another read-control transistor because the floating gate itself is just programming and erasing one data bit.

There is no clear boundary dividing the two, but the term “EEPROM” is generally used to describe non-volatile memory with small erase blocks as small as one byte and a long lifetime typically 1, cycles.

There are 32 x 8 words each of one byte. The theoretical basis of these devices is Avalanche hot-carrier injection. Siemens Forschungs und Entwicklungsberichte.

But FLOTOX’ s theoretical basis is Fowler—Nordheim tunneling hot-carrier injection through a thin silicon dioxide layer between the floating-gate and the substrate. In the above setup, I knew it of course, as I myself wrote it. Erase is via an ultraviolet light source, although in datasheeh many EPROMs are encapsulated in plastic that is opaque to UV light, making them “one-time programmable”. SPI Module of Arduino. In Maysome important research result was disclosed by Fairchild and Siemens.


Archived from the original on Finally a stop condition is provided. Archived copy as title Wikipedia articles with GND identifiers. The Japan Society of Applied Physics: Datashheet here it is: 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. Next time you call the I2C read routine, you give it an address, and again immediately say “have you got any data? Many microcontrollers include both:
