The ISP1104 Universal Serial Bus (USB) transceiver is compliant with the Universal Serial Bus Specification Rev. 2.0. It 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.
The ISP1104 USB transceiver complies with the USB Specification Rev. 2.0 and provides full‑speed (12 Mbit/s) data transfer. It features an integrated 5 V‑to‑3.3 V regulator, VBUS voltage detection, and operates from 1.65 V to 3.6 V I/O supply, making it suitable for portable devices such as mobile phones and digital cameras.
The device is offered in an HBCC16 package and includes extensive pin functions for mode selection, power‑supply configurations, and ESD protection up to ±12 kV. Detailed electrical specifications, absolute maximum ratings, and recommended operating conditions are provided for designers.
