General description
The ISP1109 is a Universal Serial Bus (USB) transceiver device that supports CEA−936−A, Mini-USB Analog Carkit Interface. It is fully compliant with Universal Serial Bus Specification Rev. 2.0. The ISP1109 can transmit and receive serial data at full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s) data rates.
The ISP1109 is available in HVQFN32 package.
