Thermal Considerations
The CP6940 has some temperature sensors which ensure operation within the specified temperature limits. Sensor data
is accessible via the Peripheral Manager. Although temperature sensing information is made available to the PM, the
CP6940 itself does not provide any active means of temperature regulation.
The Switch device and all PHYs have internal temperature diodes. Their temperature values are stored in internal regis-
ters. Additional, there are two temperature sensors for the inlet/outlet air temperature available.
As long as the temperature values stay below their upper critical threshold, all components on the CP6940 are consid-
ered to be operated within their specified temperature range.
