I²C-EEPROM 4.9
The TMPE627 provides an Atmel AT24C04 4-kbit I²C memory, which is used to store the ADC and DAC
correction data.
Although the EEPROM is not write-protected it should be generally treated as a read-only resource
for FPGA designs.
Refer to “4.12.2 Correction EEPROM” for details about the stored data. The device address will be
“1010000”.
