ATmega32M1 Main Features
The ATmega32M1 includes independent positive and negative comparator inputs to allow sen-
sorless motor control with no external active component. Three individual comparators are
available for back Electro Magnetic Field (EMF) measurements. An additional comparator is
available for over-current detection. Its reference (comparison level) can be fixed via the DAC
output or any external reference voltage. Clocked up to 64-MHz, the 12-bit versatile synchro-
nous Power Stage Controller generates 6 complementary programmable high speed and
precision signals to control the 3 half bridges of a motor. The maximum frequency is 64 kHz, with
a resulting voltage resolution of about 1/1000. Hardware fault detection will automatically and
immediately put the motor in a safe position in case a failure is detected.
