This is the DS30485A PIC18FXX39 data sheet produced by Microchip Company. The data sheet details the PIC18FXX39 Enhanced FLASH Microcontrollers with Single Phase Induction Motor Control Kernel
The PIC18FXX39 family are 8‑bit enhanced FLASH microcontrollers featuring a high‑performance RISC CPU, up to 24 KB of program memory, 1.4 KB of data memory, and a range of peripherals including multiple timers, PWM modules, ADC, USART, and a dedicated single‑phase induction motor control kernel. They operate from 2.0 V to 5.5 V and support in‑circuit serial programming and debugging.
The data sheet details pin configurations for various packages (44‑pin TQFP, 40‑pin DIP, etc.), memory organization, oscillator options, peripheral modules, motor‑control features, and electrical characteristics. Appendices cover device differences, migration notes, and revision history, while the back of the document lists worldwide sales and support contacts.
