General description
The ISP1104 Universal Serial Bus (USB) transceiver is fully compliant with the
Universal Serial Bus Specication Rev. 2.0 (full-speed section). It is ideal for use in
portable electronic devices, such as mobile phones, digital still cameras, Personal
Digital Assistants (PDAs) and Information Appliances (IAs).
It allows USB Application Specic Integrated Circuits (ASICs) and Programmable
Logic Devices (PLDs) with power supply voltages from 1.65 to 3.6 V to interface with
the physical layer of the USB. It has an integrated 5 V to 3.3 V voltage regulator for
direct powering via the USB supply line VBUS. It has an integrated voltage detector to
detect the presence of the VBUS line voltage (VCC(5.0)). When VBUS (VCC(5.0)) is lost,
the pins (D
+, D) can be shared with other serial protocols.
The ISP1104 can transmit and receive USB data at full-speed (12 Mbit/s). It allows
single and differential input modes selectable by a MODE input.
The ISP1104 is available in the HBCC16 package.
