The A0, A1 and A2 pins are no connect. I don't know what 16 byte page means because if each page was 16 bytes long then we would need 10 bit page addressing, but we only got three.
Does that mean it has eight pages of byte? The documentation also mentions the 11 bit word address.
I dunno how Arduino compiler handles that. Doesn't it need to be an 11 bit binary number? I know unsigned int..
You have used Wire. The IS24C08 only use A2 input for hardwire addressing and a total 24c04 datasheet two devices may be addressed on a single bus system.
24C01A Datasheet (data sheet) PDF
Product Datasheet Change Notice. How to access to each page in eeprom to edit data in some software like PonyProg, This pin 24c04 datasheet be left floating or tied to GND or Vcc.
You just have to write data to external eeprom using the address to where data 24c04 datasheet to be written. Now the question is that the same routines will work for 24C04 and 24C of different device specific files will be required if so from where to procure those?
I2C communication protocol with the compass module is the same as popular eeproms such as the. Pin 1 is not connected NC.

Full 4K Array. So 1st 24c04 datasheet is from 0x to 0x00FF.
Datasheet - production data. Pin 2 is the A1 device address input for the 24C The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential.
This library will work with most I2C serial EEPROM chips between 2k bits and k but there are exceptions, so read the datasheet and know your hardware. This involves sending a start condition followed by the device address word. Only if the internal write cycle has completed will the EEPROM respond with a zero allowing the read or write sequence to continue.
There are three read operations: current address read, random address read and sequential read. This address stays valid between operations as long as the chip power is maintained.
The address roll over during read is from the last byte of the last memory page to the first byte of the first page. The address roll over during write is from the last byte of the current page to the first byte of the same page.
The microcontroller does not respond with an input zero but does generate a following stop condi- tion refer to Figure 4.
Once the device address word and data word address are clocked in and acknowledged by the EEPROM, the microcontroller must generate another start condition. The microcontroller does not respond with a zero but does generate a fol- lowing stop condition refer to Figure 5.This library will work with most I2C serial EEPROM chips between 2k bits and k but there are exceptions, so read the datasheet and know your hardware.

Alberto Thx for sharing the code.
The microcontroller does not respond with a zero but does generate a fol- lowing stop condition refer to Figure 5. A read opera- tion is initiated if this bit is high and a write operation is initiated if this bit is low.
Miguel Carprog 12, views. It offers a flexible byte write and a faster byte page write. Carprog read and write eeprom 24c04 Yuri Maevski.
The two device address bits must compare to their corre- sponding hard-wired input pins. As long as the EEPROM receives an acknowledge, it will continue to increment the data word address and serially clock out sequential data words.
