2.1 PCB LAYOUT RECOMMENDATION
In the case of DIP20 devices the user should lay-
out the PCB so that the DIP20 ST7262 device and
the USB connector are centered on the same axis
ensuring that the D- and D+ lines are of equal
length. Refer to
Figure 6. Recommended PCB Layout for USB Interface with DIP20 package
