Proper Temperature Control & Noise Reduction
ZiLOG's full-feature Z8 Encore! XP with built-in
temperature sensor allows temperature
regulation in the system without the need for an
external sensor. By activating your cooling
system with an internal temperature sensor
on-chip, your application will run quieter and
your system cost will be lower.
Limited Board Space
All of ZiLOG's feature-rich performance is
compacted into a small 8-pin SOIC or QFN
package (requiring 5x6mm PCB space), so
small real-estate requirements are easily met.
Safety
For multiple safety devices to be built into your
system, this MCU includes an on-board
temperature sensor to ensure proper cooling
regulation. It also provides a fast shut down of
the PWM via on-chip comparator, which can
also be used for stall detection of the motor
with a sense resistor.
High System Cost
Highly integrated microcontroller features, such
as the transimpedance amplifier and the
temperature sensor, give you the flexibility to
reduce your overall system cost by reducing the
need for more costly external components.

On-chip integrated temperature sensor for temperature-based, closed
loop control of the fan speed and audible noise

8-Channel, 10-bit high resolution A/D converter and two independent
PWM outputs for closed loop control of two fans simultaneously, thereby
providing a cost and space saving solution

On-chip integrated analog comparator for detection of a fault condition

Low power consumption in standby modes
ZiLOG's Z8 Encore! XP Flash microcontrollers offer high-performance and
feature-rich peripherals in a portable, yet powerful 8-bit package. No other
8-bit MCU can offer the flexibility of our on-chip integrated temperature
sensor, high resolution A/D converter, and two independent PWM's in an
application-specific, cost-effective solution for intelligent fan control
applications. Add to this an extensive development tool suite and full
technical support, and you have a complete embedded control solution that
affords a fast design cycle for your end application.
