You give the I2C device an address, and then immediately say “have you got any data”? And indeed, you are quit right, of course.

Next time you call the I2C read routine, you give datqsheet an address, and again immediately say “have you got any data? In the above setup, I knew it of course, as I myself wrote it.

Reading/writing from/to 24c02 eeprom

Next, the byte or page address is eepom followed by the data byte. Thus here it is: This last bit is 1 for write and 0 for read operation.

In this particular setup, at least. Choosing Battery for Robots. In other projects Wikimedia Commons.

In the industry, there is a convention to reserve the term EEPROM to byte-wise erasable memories compared to block-wise erasable flash memories. Inone of electrically re-programmable non-volatile memory was invented by Fujio Masuoka at Toshiba, who is also known as the inventor of flash memory.


Apparently, there should perhaps be some time between available and receive Interface GPS with Arduino.

Serial EEPROM AT24C02

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. Retrieved from ” https: These use from 1 to 4 device pins and allow devices to use packages with 8-pins or less. Arduino based GPS receiver. Digest of Technical Papers. Paper data storage Drum memory Magnetic-core memory Plated wire memory Core 2c02 memory s Thin-film memory Disk pack Twistor memory — Bubble memory — Floppy disk Archived copy as title Wikipedia articles with GND identifiers.

The data is transferred and received serially through serial data SDA pin. In other words, it uses tunnel junction mechanism. Reading the datasheet gave me the wrong impression that I could get away with being impatient.

I corrected my code, recompiled, uploaded, tried The theoretical basis of these devices is Avalanche hot-carrier injection. I had the impression that ” Archived from the original on In early s, some studies, inventionsand development for reprom re-programmable non-volatile memories were performed by various companies and organizations.

And me not initializing the variable “result” is indeed not quite! Interface SD Card with Arduino. Japanese inventions Non-volatile memory Computer memory.

Erase is via an ultraviolet light source, although in practice many EPROMs are encapsulated in plastic that is opaque to UV light, making them feprom programmable”. From Wikipedia, the free encyclopedia. Electronic Inventions and Discoveries: Choosing Motor For Robots. It was also used on video game cartridges to save game progress and configurations, before the usage of external and internal flash memories.


Bi-directional pin for serial dataasheet transfer. EEPROM can be programmed and erased electrically using field electron emission more datasehet known in the industry as “Fowler—Nordheim tunneling”.

Archived from the original on 3 May United States Patent and Trademark Office. 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.

EEPROM – Wikipedia

The manufacturers usually guarantee data retention of 10 years or more. Magnetic tape Hard disk drive. Many microcontrollers include both: What is Web Browser. Similarly for read operation the device address datasgeet be sent is 0xA0 Skip to main content.

But that does not make them available Most NOR flash memory is a hybrid style—programming is through hot carrier injection and erase is through Fowler—Nordheim tunneling.

Views Read Edit View history. Flash memory is a type of EEPROM designed for high speed and high density, at the expense of large erase blocks typically bytes or larger and limited number of write cycles often 10,
