Stratix V GT Edition Reference Manual

Temperature Sense

The Stratix V GT die uses a MAX1619 temperature sense device for temperature

monitoring. The device connects to the MAX II CPLD EPM2210 System Controller

and the Stratix V GT device by a 2-wire SMB interface. The MAX1619 device is located

at slave address 0011000b (18h).

The

OVERTEMPn

and

TSENSE_ALERTn

signals are driven by the MAX1619 temperature

sense device based on a programmable threshold temperature. The

OVERTEMPn

signal

is driven to the MAX II System Controller. An over-temperature warning LED (D7)

indicates the temperature fault condition.

Table 2–43 lists the temperature sense interface pin assignments, signal names, and

functions.

Table 2–44 lists the temperature sense component reference and manufacturing

information.
