Description
The PIC16C5X series from Microchip Technology Inc., are 8-bit, high-speed, EPROM-based microcontrollers. This application note describes an implementation of an asynchronous serial I/O using a PIC16C5X micro-controller. These microcontrollers can operate at very high speeds with a minimum cycle time of 200 ns @ 20 MHz input clock. Many microcontroller applications require chip-to-chip serial data communications. Since the PIC16C5X series has no on-chip serial ports, serial communication has to be performed in software. For many cost-sensitive high volume applications, implementation of a serial I/O through software provides a more cost effective solution than dedicated logic. This application note provides code for the PIC16C5X to simulate a serial port using two I/O pins (one as input for reception and the other as output for transmission).
