Notes :
1. DQ wiring may differ from that described
in this drawing; however DQ/DM/DQS
relationships are maintained as shown.
VCCID strap connections:
(for memory device VCC, VCCQ)
Strap out (open): VCC = VCCQ
Strap in (closed): VCC
≠
VCCQ
2. The SDA pull-up registor is reguired due to
the open-drain/open-collector output.
3. The SCL pull-up registor is recommended,
because of the normal SCL lime inactive
"high" state.
