USB1T20
Universal Serial Bus Transceiver
General Description
The USB1T20 is a generic USB 2.0 compliant transceiver.
Using a single voltage supply, the USB1T20 provides an
ideal USB interface solution for any electronic device able
to supply 3.0V to 3.6V. It is designed to allow 5.0V or 3.3V
programmable and standard logic to interface with the
physical layer of the Universal Serial Bus. It is capable of
transmitting and receiving serial data at both full speed
(12Mbit/s) and low speed (1.5Mbit/s) data rates.
Packaged in industry standard TSSOP and Fairchild鈥檚
ultra-small 2.5mm x 2.5mm MLP package, the USB1T20 is
ideal for ultra-portable electronics and other space con-
strained applications.
