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.
