INTRODUCTION
SDA
PIC16C5X microcontrollers from Microchip are ideally suited for use as smart peripheral devices under the control of the main processors in systems, due to their low cost and high speed. They are capable of performing tasks which would simply overload a conventional microprocessor, or require considerable logic circuitry, at a cost competitive with lower mid-range PLDs. To minimize the engineering overhead of adding multiple controllers to a product, it is convenient for the auxiliary controllers to emulate standard I/O peripherals. A common interface found in existing products is the I2C bus.
