Application Circuits

Crystal or Ceramic Resonator for Multiple I/O Applications for HT82B40R

Note:

The resistance and capacitance for the reset circuit should be designed in such a way as to ensure that the

VDD is stable and remains within a valid operating voltage range before bringing RES high.

Components with * are used for EMC issue.
