Is the external crystal ( HXT ) voltage of the M480 series and M451 series limited by 0.3VDD and 0.7VDD, the same as the external clock source voltage?  日付:2018-09-03

The external crystal ( HXT ) voltage of the M480 series and M451 series is different from the external clock source voltage. There are two specifications as described below: 

1. The following table shows the specifications of the HXT voltage, which is an internal digital signal, independent of 0.7 VDD.

  • M480 Series

  • M451 Series

2. The external clock source can be high level and low level according to the state of the I / O; thus, there is a limit of 0.3 VDD and 0.7 VDD.

The external clock source limits of the M480 series and M451 series are the same.
