PIC24EP512MC202 - ciekawy 16-bitowiec

Kolejny ciekawy mikrokontroler z rodziny 16-bitowców popędzany 70MHz. Potężna ilość dostępnej pamięci i bogate peryferia m.in. dedykowane do sterowania silnikami w tym Motor Control PWM i Quadrature Encoder Interface (QEI) . Przyda się do budowy robotów. Dostępny w obudowie DIP28. Cena 3.75 EUR u producenta wygląda na mocno atrakcyjną w stosunku do możliwości i wyposażenia. Można kupić nawet i 1 sztukę .

Z mnieszą pamięcią cena jest odpowiednio niższa.

Bogactwo wyboru to jest to co pokochałem m.in. w PIC a jak mówi porzekadło ludowe „od przybytku głowa nie boli”.

The 70 MIPS PIC24E Motor Control MCUs with enhanced on-chip peripherals enable the design of high-performance, precision motor control systems that are more energy efficient, quieter in operation, have a great range and extended life. They can be used to control brushless DC, permanent magnet synchronous, AC induction and stepper motors. These devices are also ideal for high-performance general purpose applications.
