◆Specification for Quartz Crystal
◆Qualification item for Oscillation circuit characteristics
◆Approximate expression for Circuit load capacitance
◆Notes for the design of Circuit board
Please keep the wiring short and place Quartz Crystal, Condensor, and Resistance
close as possible to Lapis microcontroller. In order to prevent interference with other signal lines,
do not provide other signal lines, please do not provide other signal lines on the crystal
mounting part (bottom surface).

◆Notes
The above evaluation results are reference values evaluated in the specific sample,
and the contents are not guaranteed.
Please note that in the actual circuit board, the value of the external element capacitance
and the characteristics may change depending on the difference in stray capacitance and so on.
