Product data
1. General description
The ISP1104 Universal Serial Bus (USB) transceiver is compliant with the
Universal
Serial Bus Speci鏗乧ation 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 Speci鏗乧 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 V
BUS
. It has an integrated voltage detector
to detect the presence of the V
BUS
line voltage (V
CC(5.0)
). When V
BUS
(V
CC(5.0)
) is lost,
the D+ and D鈭?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.
