This family offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price – with the addition of high-endurance Enhanced FLASH program memory. The PIC18F2539 family also provides an off-the-shelf solution for simple motor control applications, allowing users to create speed control solutions with small part counts and short development times.
