4.23 GPIO Electrical Characteristics
The four GPIO signals routed to the P0 of MVME8100 and P2 connectors have the following
electrical characteristics:
4.24 Thermal Management
The MVME8100 / MVME8110 provides three on-board temperature sensors using an ADT7461
dual temperature sensor and a TMP112A temperature sensor. The ADT7461 internal
temperature sensor provides the temperature at the board edge on the CPU side of the board.
The ADT7461 remote temperature sensor measures the CPU temperature. The ADT7461 can
measure negative temperatures down to -64C with +/- 1C accuracy on the remote sensor and
+/- 3C accuracy on the internal sensor. The ADT7461 registers can be used to configure the low
temperature limit and high temperature limit for the local sensor as well as for the remote
sensor. An interrupt can be generated if limits are exceeded. The TMP112A temperature sensor
is used to measure the temperature at the board edge opposite from the CPU. Since the airflow
direction can be different in some VME chassis, either temperature sensor can be used to get a
measure of the board inlet air temperature, depending on the air flow direction.
