The PIC18F14K50-I/SO is a 20-pin USB Flash Microcontroller with XLP technology. This PIC® Microcontroller features a full speed USB 2.0 compliant interface that can automatically change clock sources and power levels upon connection to a host, making it an exceptional device for battery-powered applications. The addition of mTouch™ touch sensing compatibility, a 10-bit ADC, motor control PWMs and a host of serial interfaces make the PIC18F14K50 the perfect device to Just add USB to any application. The oscillator module has a variety of clock sources and features that allow it to be used in a wide range of applications, maximizing performance and minimizing power consumption. The two-speed start-up mode provides additional power savings by minimizing the latency between external Oscillator Start-up Timer (OST) and code execution.
