Functional Description (Continued)
Power Supply Configurations and Options
The three modes of power-supply operation are:
Normal Mode – The VIO and VREG3V3 pins are
connected. VIO is an independent voltage source
(1.65 to 3.6V) that is a function of the external
circuit configuration.
Disable Mode – VIO is not connected; VREG3V3 is
connected. In this mode, the D+, D- pins are three-
state and the device enters low-power (suspended)
state upon detection of VIO lost.
Hi-Z Mode – When the Hi-Z pin is pulled HIGH, with
VREG3V3 powered, the RCV/VP/VM interface can
be used to access the Baseband for production test
programming. VP/VM/RCV are in high impedance
states.
Sharing Mode – VIO is the only supply connected. In
this mode, the D+ and D- pins are three-state and
the FUSB1500 allows external signals up to 3.6V to
share the D+ and D- bus lines. Internally, the
circuitry limits leakage from the D+ and D- pins
(maximum 10
A) and V
IO such that device is in low-
power (suspended) state. The VP and VM pins are
driven HIGH and RCV is forced LOW as an
indication of this mode. Can be used for production
test programming via D+/D-. to UART or Baseband
processor. HiZ is to be Low or Floating to ensure
VP/VM/RCV is signaled to processor.
A summary of the supply configurations is described in
Table 5.

Single Ended Zero Detection Timing
The SE0 detection logic is activated when entering the
state “011” (SUSPND, CONFIG, and SPEED_N) and
the logic waits to detect an SE0 event. Since the
FUSB1500 can also be used as an LS host device, it is
important to ensure that the tLST time for the USB2.0
specification is met. tLST is the minimum time to not
interpret LS differential signaling as an SE0 and is
210ns in duration. Similarly for FS differential signaling,
there is a time period, tFST time, of 14ns.
Seeing an SE0 for greater than tLST results in the INT_N
pin toggling LOW. The FUSB1500 is designed for 260ns
(typical).
Exiting HiZ or Suspend Mode Timing
As the RCV path is required to maintain the previous
state through an SE0 event, there is the possibility when
exiting HiZ or Suspend Mode to have the previous result
stored. The transition through the SE0 decode logic is
such that software should ignore RCV for at least 100ns
when exiting HiZ mode to ensure the correct D+/D- state
is available on the RCV output.
