OVERVIEW

This data sheet covers the PIC17C4X group of the PIC17CXX family of microcontrollers. The following devices are discussed in this data sheet:

• PIC17C42

• PIC17CR42

• PIC17C42A

• PIC17C43

• PIC17CR43

• PIC17C44

The PIC17CR42, PIC17C42A, PIC17C43, PIC17CR43, and PIC17C44 devices include architectural enhancements over the PIC17C42. These enhancements will be discussed throughout this data sheet.
