Heat dissipation specifications
5.1
Heat dissipation instructions
MLU290-M5 Intelligent Accelerating Card adopts passive heat dissipation mode.
5.2
Maximum operating temperature
Maximum operating temperature means the recommended maximum operating temperature
(junction temperature Tj) of MLU290-M5. Junction temperature is obtained through the chip built-in
temperature sensor at the software interface through instructions. It is recommended to control the
maximum operating temperature of the main chip of MLU290-M5 below 95
℃
.
5.3
Slowdown temperature
Slowdown temperature means the temperature point which the IPU frequency is reduced.The
slowdown temperature of MLU290-M5 is 97
℃
.
5.4
Shutdown temperature
Shutdown temperature means the temperature point which the power is cut off. The shutdown
temperature should not be triggered during normal operation, and the system may have a catastrophic
damage when the shutdown temperature is triggered. The shutdown temperature of MLU290-M5 is
100
℃
.
When the chip junction temperature of MLU290-M5 reaches 100
℃
, the THERMTRIP# signal
will be triggered and the power supply of MLU290-M5 will be cut off after 1s. After the power is cut
off, it is recommended to eliminate the heat dissipation problem manually before restart.
