PVT sensor
The Juno r2 SoC provides a
Power, Voltage, and Temperature
(PVT) sensor that powers down the chip
when it exceeds the maximum operating temperature. It also selectively powers down parts of the chip
when it exceeds the temperature budget.
The PVT sensor is calibrated during board manufacture.
