There are 8 ADC channels, an analog comparator, 3 timers and four PWM channels. The device contains an internal
1MHz, 2MHz, 4MHz or 8MHz RC oscillator, and defaults to the 1MHz clock.
Power Supply vs. Maximum Frequency
The ATmega8535 is specified at a power supply voltage of 2.7V to 5.5V, 16MHz maximum frequency. It is rated 8MHz
from 2.7V to 4.0V, and 16MHz above that.
