The ISP1102 Universal Serial Bus (USB) transceiver is fully compliant with the Universal Serial Bus Specification Rev. 2.0. It can transmit and receive USB data at full-speed (12 Mbit/s). The transceiver allows USB Application Specific ICs (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. The transceiver has an integrated voltage detector to detect the presence of the VBUS voltage (VCC(5.0)). When VCC(5.0) or Vreg(3.3) is lost, the D+ and D- pins can be shared with other serial protocols. The transceiver is a bi-directional differential interface and is available in HBCC16 and HVQFN14 packages. It is ideal for use in portable electronic devices, such as mobile phones, digital still cameras, personal digital assistants and information appliances.
The ISP1102 is a Universal Serial Bus (USB) transceiver fully compliant with USB Specification Rev. 2.0. It supports full‑speed data transfer (12 Mbit/s) and can operate from 1.65 V to 3.6 V I/O supply voltages, with an integrated 5 V‑to‑3.3 V regulator for USB bus power.
Key features include bi‑directional differential I/O, voltage‑bus detection, low‑power suspend mode, and robust ESD protection (±12 kV for HBCC, ±7 kV for HVQFN). The device is offered in HBCC16 and HVQFN14 packages and is intended for portable electronics such as mobile phones, digital cameras, PDAs, and other information appliances.
