PIC'ing the MAX3100: Adding USB to a PIC Microcontroller Using the MAX3100 UART

Application circuit consists of the MAX3100 UART, a FT232BM UART-to-USB converter, a 93C46 serial EEPROM and a PIC16F84 microcontroller. Since the PIC16F84 does not have any internal USB or UART peripherals, the MAX3100 makes the perfect external UART peripheral
