General description
The ISP1102 Universal Serial Bus (USB) transceiver is fully compliant withUniversal Serial Bus Specification Rev. 2.0. The ISP1102 can transmit and receive USB data at full-speed (12 Mbit/s).
The transceiver 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. The transceiver has an integrated 5 V-to-3.3 V voltage regulator for direct powering through USB supply line VBUS. The transceiver has an integrated voltage detector to detect the presence of the VBUSvoltage (VCC(5V0)). When VCC(5V0)or VREG3V3 is lost, the DP and DM pins can be shared with other serial protocols.
