DEVICE OVERVIEW

This document contains device-specific information for the following devices:

? PIC18F65J50 ? PIC18F85J50

? PIC18F66J50 ? PIC18F86J50

? PIC18F66J55 ? PIC18F86J55

? PIC18F67J50 ? PIC18F87J50

This family introduces a new line of low-voltage USB microcontrollers with the main traditional advantage of all PIC18 microcontrollers – namely, high computational performance and a rich feature set – at an extremely competitive price point. These features make the PIC18F87J50 family a logical choice for many high-performance applications, where cost is a primary consideration.
