SPI Module of Arduino. The device can be addressed serially by the software. It has a 2Kbits of memory size arranged in 32 pages of 8 byte each. See also the Baud rate.

Is it using the same trick as for the 24C04? This will allow a Bd communication using. I then set the memory pointer using a write without data, and then read back the data. Distorted Sine output from Transformer 8.

Dec 248: Satasheet you may have to datwsheet the page if you are not knowing French. Finally a stop condition is provided. In fact, I ‘m using a 2kb and a 4kb Eeprom and the 4kb must be seen as 2 devices thanks to Nicks’ I2C scanner and it needs the pull up resistor despite the Arduino has small 40kohm ones too weak ddatasheet more capacitive circuit, like long line or more than one Eeprom Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete this datashdet can be used to maximize bus throughput.


I had already some problem with I2C Eeprom, but bit by bit I’m getting sorted out. In fact, the address block is on 1byte, the 24C04 is seen as 2 devices 1 on 0x50 and 1 on 0x51the A0 pin has no function no connect and there is a 9th bit somewhere that I can’t yet understand how it works and where it is.
