1. USB Transceiver
2. D+ Pull-Up Control
3. Detection of USB Cable Connection/Disconnection
REJ09B0467-0350 Rev. 3.50
Jul 07, 2010
This module supports the on-chip transceiver only, not the external transceiver.
The general output port (P20) is used for D+ pull-up control pin. The P20 pin is driven high by
the PULLUP_E bit of CTLR when the USB cable VBUS is connected.
Thus, USB host/hub connection notification (D+ pill-up) is enabled.
As USB states, etc., are managed by hardware in this module, a VBUS signal that recognizes
connection/disconnection is necessary. The power supply signal (VBUS) in the USB cable is
used for this purpose. However, if the cable is connected to the USB host/hub when the
function (system installing this LSI) power is off, a voltage (5 V) will be applied from the USB
host/hub. Therefore, an IC (such as an HD74LV1G08A or 2G08A) that allows voltage
application when the system power is off should be connected externally.

Reduce voltage to the operating voltage of this LSI (3.3 V).
To protect this LSI from being damaged, use the IC (such as HD74LV-A Series) which can
be applied voltage even when the system power is turned off.
Prevent noise from the VBUS pin while the USB is performing communication.
