(a) CS_N = “H”
(b) WR0 N = “H” and WR1_N = “H”
(a) input:
(b) Input (Hi-Z):
(c) H, L, H/L:
The input level of MPBUS pin must be fixed. Do not switch the level during controller operations.
Pin is for OUTPUT when CS N = “L” and RD N=”L”, otherwise INPUT.
Hi-Z input (open) is enabled when MPBUS = “H”.
Maintain status (a) or (b) as described below during reset and immediately after reset release for CS_N, WR0_N
and WR1_N signals.

When Host Controller function is selected:
leave open or connect directly to Vbus of USB
bus.
device.
When Peripheral Controller function is
selected: Connect directly to Vbus of USB bus.
Can detect Vbus connection/disconnection.
Connect to 5V when not connecting to Vbus.
Connect to analog GND pin through 5.6kΩ±1%
resistor.
When using USB Mini-AB receptacle, connect
to ID pin.
Used for ON/OFF output to external power
circuit. Connect to external power circuit for
Vbus supply.
VBOUT1 pin cannot be used when using
DP0/DM0 as OTG.
Used for input of over-current detection from
external power circuit. Connect to PORT0
external power circuit.
When input for over-current detection from
external power circuit is one pin, connect to
OVCUR0A and fix OVCUR0B to High or Low.
Used for input of over-current detection from
external power circuit. Connect to PORT1
external power circuit.
OVCUR1 pin cannot be used when using
DP0/DM0 as OTG.
Used for low-power consumption mode
ON/OFF switch when external power circuit
has low-consumption mode. Connect to
PORT0 external power circuit.
Connect to 3.3V or 1.8V.
Output 1.5V with internal regulator –generated.
For stability core power, Connect the 4.7uF
and 0.1uF capacitor between GND.
No connection of external power is necessary.
Connect to 3.3V.
Connect to 3.3V.
This pin cannot supply Vbus to the connected
