Product data sheet
1. Introduction
The Nexperia PNX0161 is an integrated IC that serves as USB audio and HID class
device for a USB headset.
2. General description
Recent development in mobile phones is to have the phone equipped with a
USB micro A plug as a single plug for charging and connection to all enhancements (like a
headset, but also for other enhancements like GPS accessories etc.)
The PNX0161 is based on an ARM7TDMI CPU core with data/instruction cache of 8 kB
and USB 2.0 FS device interface.
