ISP1104
Advanced Universal Serial Bus transceiver
Rev. 02 — 14 October 2003
Product data
1. General description
The ISP1104 Universal Serial Bus (USB) transceiver is compliant with the Universal
Serial Bus Specification Rev. 2.0. 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.
It allows USB Application Specific Integrated Circuits (ASICs) and Programmable
Logic Devices (PLDs) with power supply voltages from 1.65 V 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 D+ and D− pins can be shared with other serial protocols.
The ISP1104 is available in HBCC16 package.
The ISP1104 is ideal for use in portable electronic devices, such as mobile phones,
digital still cameras, personal digital assistants and information appliances.

[1] Signal levels on pins D+ and D− are determined by other USB devices and external pull-up or
pull-down resistors.
[2] In the suspend mode (pin SUSPND = HIGH), the differential receiver is inactive and the output RCV is
always LOW. Out-of-suspend (K) signalling is detected via the single-ended receivers VP and VM.
