5.6 Board ID EEPROM

The ULP-COM sA3874i module includes an I2C serial EEPROM available on the I2C_PM bus. An Atmel 24C32 or
equivalent EEPROM is used in the module. The device operates at 1.8V. The Module serial EEPROM is placed at I2C
slave addresses A2 A1 A0 set to 0 (I2C slave address 50 hex, 7 bit address format or A0 / A1 hex, 8 bit format)
(for I2C EEPROMs, address bits A6 A5 A4 A3 are set to binary 0101 convention).

The module serial EEPROM is intended to retain module parameter information, including serial number. The
module serial EEPROM data structure conforms to the PICMG® EEEP Embedded EEPROM Specification.
