EEPROM writing
EEPROM reading
Please note that in order to guarantee reliable EEPROM writing operation it is very critical to follow
the requirements below. The minimum value for supply voltage at +25 °C temperature is 3.0 V
during EEPROM register write operation. The peak current consumption is also significantly higher
than in normal operation (~2 mA for 15 ms period per byte).
Example of WRITE operation to EEPROM register 0x29 (write 0xAA to EEPROM register 0x29):
The EEPROM can be read with nominal supply voltage, but the peak current consumption is
significantly higher than in normal operation (~1.5 mA for 20 µs period per byte).
Example of READ operation from EEPROM register 0x29 (read EEPROM register 0x29):

Write 0x29 in direct register ADDPTR (0x02)
Write 0xAA in direct register DATAWR (0x01)
Write 0x06 in direct register OPERATION (0x03)
Wait 50 ms
Write 0x29 in direct register ADDPTR (0x02)
Write 0x05 in direct register OPERATION (0x03)
Wait 15 ms (minimum wait value)
Read direct register DATARD8 (0x1F for SPI, 0x7F for TWI), the register content is in bits
[7:0], see section 3.2 for further information.
