User manual

Energy Efficiency
Ability to run the motor at slower speeds reduces
power consumption. Our 2µs ADC with time
stamp is tied to the PWM module and allows
you more accurate control of the motor at lower
or variable speeds.
Quiet Operation
Keep your HVAC system’s audible noise low by
using the soft start feature and ability to adjust
the speed of the motor by using our advanced
analog motor control features.
Design Flexibility
Microcontroller based HVAC design allows for
ability to add more complex and differentiating
features. With 16K of Flash and 17 GPIO you
are able to add many bells and whistles to
differentiate your product.
Low System Cost
Highly integrated microcontroller features, such
as the op-amp and comparator, give you the
ability to reduce your overall system cost.
Communication
Use the advantage of integrated multiple
communication peripherals for complete system
level communication.

ZiLOG’s high performance Z8 Encore! MC™ 8-bit microcontrollers provide a
simple solution for controlling the motors of HVAC systems. Heating,
Ventilation, and Air Conditioning (HVAC) industry today is not only
concerned with improving the air quality and comfort levels of the
consumers, but also trying to meet the demanding energy efficiency
standards and ever increasing need for differentiating features. To keep up
with these trends, HVAC designs greatly benefit from the advanced features
of microcontrollers (MCUs) such as the Z8FMC16100 series of Z8 Encore!
MC™ motor control devices.
