ISP1110
General Description
The ISP1110 is a Universal Serial Bus (USB) transceiver that supports Universal Asynchronous Receiver-Transmitter (UART) signaling mode.
The ISP1110 USB transceiver is fully compliant with Universal Serial Bus Specification Rev. 2.0. The ISP1110 can transmit and receive USB data at full-speed (12 Mbit/s).
The ISP1110 transceiver allows USB Application Specific Integrated Circuits (ASICs) with I/O power supply voltage from 1.65 V to 2.85 V to interface to 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 and an integrated voltage detector to detect the presence of the VBUS voltage on the VCC(5V0) pin. When VBUS is present, the transceiver is in USB mode. When VBUS is not present, the transceiver can be set to UART signaling mode.
The ISP1110 transceiver is available in HBCC16 lead-free and halogen-free package.
