ISP1110
Universal Serial Bus transceiver with UART signaling
Rev. 02 — 19 March 2007
Product data sheet
1. 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 V
BUS
and an integrated voltage detector to detect the presence
of the V
BUS
voltage on the V
CC(5V0)
pin. When V
BUS
is present, the transceiver is in USB
mode. When V
BUS
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.
