A.2.2.2. Temperature Monitoring

A temperature sensing device (MAX6581) monitors the temperature of the Intel® Stratix® 10 DX FPGA device. The Intel® Stratix® 10 DX FPGA device has seven die temperature diodes. The MAX6581 device senses these diodes and convert the signals to a digital form for the Intel® MAX® 10 device that can be read via a I2C bus.

Additionally, the OVERTEMPn and ALERTn signals from the MAX6581 allow Intel® MAX® 10 device to immediately sense a temperature fault condition. The Intel® MAX® 10 device controls the over temperature warning LED (D40, red-colored) to indicate an over temperature fault condition. Temperature fault set points can be programmed into the MAX6581 device.
