DataLogger application
This RF EEPROM application demonstrates a practical application of the M24LR64. It is
able to record and store 64 Kbits of temperature data using the M24LR64-R Dual interface
EEPROM (I
communicates with the M24LR64-R using its serial interface and controls an STTS751
digital temperature sensor.

X = number of digits in price (max 7)
YYYYYYY = price value including decimal separator (.) coded in hexadecimal. For instance
0x512A99FF means 5 digits and price is 12.99
