Temperature sensor and EEPROM

A temperature sensor SE97BTP is populated on the MBa8Xx to monitor the temperature. The same type of sensor is also used on

the TQMa8Xx. Both sensors are read out via I2C1, see Table 10.
The sensor address on the MBa8Xx can be changed by reassembling resistors. When changing the address, care must be taken to

avoid address conflicts with existing I

2

C devices, see Table 10. The assembly options are documented in the MBa8Xx schematics.

The SE97BTP has an additional EEPROM. Further specifications of the SE97BTP can be found in the data sheet.

The alarm output EVENT# of the SE97BTP is not connected and is not available on the MBa8Xx.

Block diagram temperature sensor

The I²C addresses of the temperature sensor and the EEPROM are determined by the input level of pins A0, A1 and A2, among

other things. The I²C addresses can be changed according to the following table by a resistor reassembly.

Details can be taken from the MBa8Xx schematics.
