3. MCU
The
ATtinny44 MCU works as a I2C memory, storing the SYZYGY™ DNA information and the Calibration Coefficients. The J5
connector is used for programming the MCU and the SYZYGY™ DNA at manufacturing.
The DNA and the Factory Calibration Coefficients are stored in the Flash memory of the MCU, which appears to the I2C interface as
“read-only”. The User Calibration Coefficients are stored in the EEPROM () memory of the MCU, which is write-protected via a magic
number at a magic address. The memory structure can be consulted below.
