USB1T1102 USB1T1102R (Preliminary)
Universal Serial Bus Peripheral Transceiver
with Voltage Regulator
General Description
This chip provides a USB Transceiver functionality with a
voltage regulator that is compliant to USB Specification
Rev 2.0. this integrated 5V to 3.3V regulator allows inter-
facing of USB Application specific devices with supply volt-
ages ranging from 1.65V to 3.6V with the physical layer of
Universal Serial Bus. It is capable of operating at 12Mbits/s
(full speed) data rates and hence is fully compliant to USB
Specification Rev 2.0. The Vbusmon pin allows for monitor-
ing the Vbus line.
The USB1T1102 also provides exceptional ESD protection
with 15kV contact HBM on D+, Dpins.
Features
s Complies with Universal Serial Bus Specification 2.0
s Integrated 5V to 3.3V voltage regulator for powering
VBus
s Utilizes digital inputs and outputs to transmit and receive
USB cable data
s Supports full speed (12Mbits/s) data rates
s Ideal for portable electronic devices
s MLP technology package (16 pin) with HBCC footprint
s 15kV contact HBM ESD protection on bus pins

ESD Protection
ESD Performance of the USB1T1102
HBM D+/D: 15.0kV
HBM, all other pins (Mil-Std 883E): 6.5kV
ESD Protection: D+/DPins
Since the differential pins of a USB transceiver may be
subjected to extreme ESD voltages, additional immunity
has been included in the D+ and Dpins without compro-
mising performance. The USB1T1102 differential pins have
ESD protection to the following limits:
15kV using the contact Human Body Model
8kV using the Contact Discharge method as specified in
IEC 61000-4-2
Human Body Model
Figure 1 shows the schematic representation of the Human
Body Model ESD event. Figure 2 is the ideal waveform rep-
resentation of the Human Body Model.
IEC 61000-4-2, IEC 60749-26 and IEC 60749-27
The IEC 61000-4-2 standard covers ESD testing and per-
formance of finished equipment, and as such evaluates the
equipment in its entirety for ESD immunity. Fairchild
Semiconductor has evaluated this device using the
IEC 6100-4-2 representative system model depicted in Fig-
ure 3. Under the additional standards set forth by the IEC,
this device is also compliant with IEC 60749-26 (HBM) and
IEC 60749-27 (MM).

odologies and performance levels, please contact Fairchild
