    i want to design a tachometer,it receives inputs from a counter every 0.25 seconds and calculate the average for 4 values and multiply by 240 so that it is equal to 1 minute and disply it on the LCD but the problem is which PIC microcontroller can i use.It must have maybe 40 or 28 pins

    i would want know which microchip microcontroller can i use to multiply, divide and convert binary value to decimal and display on LCD.
