PIC18F2539 28-pin 24kB Microcontroller Datasheet

The Microchip PIC18F2539 Microcontroller is a specially designed 28-pin 8-bit PIC Microcontroller for Motor Control Applications. An integrated motor control kernal utilises Pulse Width Modulation to provide speed control for single phase induction motors. The PIC18F4539 microcontroller has 24kB of high-endurance Flash Program Memory and a Five Channel 10-bit Accuracy A/D Converter.
