PIC18F Family: Microcontrollers Microchip unveiled the new 8-bit flash microcontroller family. The new device features an advanced motor control periphery that provides higher performance, lower noise, wider range of use, and extended motor life for automotive, industrial, appliance and consumer applications. Microchip’s 40-pin PIC18F4331 / 4431 and 28-pin PIC18F2331 / 2431 microcontrollers feature analog and digital feedback and a new three-phase compensated pulse width modulation (PWM) control system that provides a complete solution for complex motor control applications. The good performance and flexibility of the PIC18Fxx31 family of devices is demonstrated in its three modules, the power control module uses a three-phase PWM structure; the motion feedback module includes a quadrature encoder interface; the third module consists of a high-speed analog-to-digital converter composition,
