ISP1109 is a 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.
The ISP1109 is a Universal Serial Bus (USB) transceiver that supports the CEA‑936‑A Mini‑USB analog carkit interface and complies with USB Specification Rev. 2.0. It can operate at both full‑speed (12 Mbit/s) and low‑speed (1.5 Mbit/s) data rates and includes UART pass‑through, analog audio switches, and OTG session request support.
The device is supplied in a compact HVQFN32 package (5 × 5 × 0.85 mm), operates from 3.0 V to 5.25 V (I/O 1.65 V‑3.6 V), and features low power‑down consumption (< 20 µA) and robust ESD protection (12 kV). It is intended for mobile phone applications and other devices requiring USB carkit functionality.
