Description
The FUSB1500 is a USB2.0 FS/LS transceiver with
resistive charger detection. It is compliant with the
Universal Serial Bus Specification, Rev. 2.0 (USB2.0).
Ideal for portable electronic devices; such as mobile
phones, digital still cameras, and personal digital
assistants; it allows USB Application Specific ICs
(ASICs) and Programmable Logic Devices (PLDs) with
power supply voltages from 1.65V to 3.6V to interface
with the physical layer of the Universal Serial Bus.
The FUSB1500 can be used as a USB device
transceiver or a USB host transceiver. It can transmit
and receive serial data at both full-speed (12Mbps) and
low-speed (1.5Mbps) data rates.
The FUSB1500 supports the SE Mode controller
interface.

Functional Description (Continued)
Extended Control Mode
This block of control has a multi-function role; it is used
to signal a SE0 detect to the host via INT_N and uses a
weak resistor pull-up method for charger detection.
Note that the signaling of SE0 via INT_N is only enabled
for the state “011” and all SE0 events can still be
decoded from the VP, VM, and RCV outputs.
When the three inputs (SUSPND, CONFIG, and
SPEED_N) are not “011,” INT_N is not active; the SE0
detector (RCV = 0) is not active and its latch is set to
HIGH. When the “011” is seen on the inputs, the
FUSB1500/1501 is waiting for an SE0 event. When the
SE0 event (deglitched) is detected, INT_N goes active
(HL transition). The host detects this INT_N signal and
configures the inputs to the pattern “110” or “010” to
keep the 1.5k pull-up enabled. The INT_N signal is
then de-asserted and the SE0 detector reset.
If a code other than “010” or “110” is written, the mode
configuration is a function as described in Table 4 and the
SE0 detector and INT_N are de-asserted to reset states.
When entering the state “111,” which enables the weak
pull up resistor for charger detection, the D+/D- drivers
are automatically configured to USB receive mode
(equivalent to OE_N HIGH).
Figure 10 shows the extended control logic and Table 4
the truth table for the extended control.
