Temperature Sensor
The Pico E-15 contains one temperature sensor that directly senses the die temperature of the
Virex-4 FPGA. The digital interface of the remote temperature sensing chip is connected to the
Cypress PSoC. If an overtemperature condition occurs, the PSoC will shutdown the FPGA
until the temperature has dropped sufficiently below the shutdown threshold.
The setpoints of the temperature shutdown circuit can be reprogrammed via the PSoC debug
cable.
