●This document contains device-specific information for the following devices:
●• PIC18F24J50 • PIC18LF24J50
●• PIC18F25J50 • PIC18LF25J50
●• PIC18F26J50 • PIC18LF26J50
●• PIC18F44J50 • PIC18LF44J50
●• PIC18F45J50 • PIC18LF45J50
●• PIC18F46J50 • PIC18LF46J50
●This family introduces a new line of low-voltage Universal Serial Bus (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 PIC18F46J50 family a logical choice for many high-performance applications, where cost is a primary consideration.
