    en.wikipedia.org/wiki/Hitachi_HD44780_LCD_controller

    The data sheet indicates that for a resistor of 91 kΩ at V CC =5 V the oscillator can vary between 190 kHz and 350 kHz resulting in wait times of 52.6 μs and 28.6 μs instead of 37 μs. If a display with the recommended 91 kΩ resistor is powered from 3.3 volts the oscillator will run much slower.
