(1)

Value guaranteed by design, not 100% tested in production.

(2)

All main power and ground pins should be connected to an external power source within the allowable range.

(3)

It is recommended that VDD and VDDA are powered by the same source. The maximum difference between

VDD and VDDA does not exceed 300 mV during power-up and operation.

(4)

The device junction temperature must be kept below maximum TJ. More information could be found in AN166

Design Guide for Thermal Characteristics of GD32H7xx series.

(5)

VIN maximum value cannot exceed 5.5 V.

(6)

For grade 6 devices, the parameter of TA=85°C, For grade 7 devices, the parameter of TA=105°C.
