Temperature Sensing Operation for Arria 10 Devices

Figure 1: Altera Temperature Sensor IP Core Top-Level Diagram for Arria 10 Devices

The following lists the features for Altera Temperature Sensor IP core for Arria 10 devices:

• For Arria 10 devices, the Altera Temperature Sensor IP core supports the instantiation of temperature

sensor block in your design from the IP Catalog.

• The Arria 10 temperature sensor block runs at 1 MHz, where the clock signal is coming from the

internal oscillator. Within the block, 10-bit ADC circuitry is included for converting sensor’s reading

to digital output.

• The corectl signal is used as an enable signal. When asserting the corectl signal, the ADC starts the

conversion and 10-bit data is available at tempout after 1,024 clock cycles. The eoc signal goes high for

one clock cycle indicating end of conversion. You can latch the data on tempout at the falling edge of

eoc.

• You can reset the temperature sensor anytime by asserting the reset signal.
