PR533
USB NFC integrated reader solution
10.24 Temperature sensor
[1] The temperature sensor embedded in the PR533 is not intended to monitor the temperature. Its purpose is
to prevent destruction of the IC due to excessive heat. The external application should include circuitry to
ensure that the ambient temperature does not exceed 85 C as specified in Table 5 “
Operating conditions”.
