The PIC18F13K50 and PIC18F14K50 (PIC18F1XK50) are low cost USB MCUs that provide a host of features not normally found on inexpensive 8-bit MCUs - enabling the addition of embedded USB into a wide range of applications. The MCUs include a host of serial communications interfaces, such as USB 2.0, I2C, SPI and USART; enabling them to transfer data between USB and other embedded serial networks. Additionally, they provide a 10-bit, 9-channel ADC and dual comparators with S/R Latch.
