2.7.1 Notes of Target System Board Layout
The following shows the notes of target system board layout
- The length of a cable connecting EASE1000 with the target system (EASE1000 interface cable) is approximately 15
cm. Locate the EASE1000 interface connector at the end of PCB if possible in order to make the cable between the
EASE1000 interface connector and target LSI as short as possible.
(Compatible connector: HIF3FC-14PA-2.54DSA)
- It is recommended that the wiring connected to RST_OUT/SCK and SDATA be shielded with Vss
