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.
