Application Circuits

Crystal or Ceramic Resonator for Multiple I/O Applications for HT82K95E

Note: The resistance and capacitance for 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 to high.

X1 can use 6MHz or 12MHz, X1 as close OSC1 & OSC2 as possible.

Components with * are used for EMC issue.

Components with ** are used for resonator only if necessary.

Components with *** are used for 12MHz application.
