MCU footprint design notes
Figure 2 shows the recommended dimensions of the footprint for mounting the NQPACK on the
printed circuit board of the user system.
The printed circuit board of the user system must be designed with due consideration given to this
footprint as well as to the mass production MCU.
For more information, contact Tokyo Eletech Corporation.

Notes on the subclock
When using this product, it is not possible to supply the subclock from the user system to the evalu-
ation MCU. If the evaluation MCU operates using the subclock, use the subclock on the adapter
board.
See the operation manual for the adapter board for details.

*1 : The positions of the holes (
φ
1.0mm) for the guide pins when the NQPACK is mounted.
These holes are not needed if the guide pins are not used.
*2 : The position of the screw hole (
φ
1.6mm) used to affix the IC socket when the NQPACK064SD-ND-
SL (Tokyo Eletech Corporation, sold separately) is mounted. This hole is not needed if the
