User manual

Accurate Output Signal Measurement
For accurate signal measurement with external
gain settings, this MCU has a built-in
transimpedance amplifier (op-amp) that allows
your sensor interfacing to not be limited by
your MCU's fixed amplification. In addition,
the high accuracy differential input ADC can
provide up to 14-bits of accuracy with software
calibration.
Proper Temperature Detection
The built-in temperature sensor on the Z8
Encore! XP can be used to automatically
calibrate the processed sensor output, such as
the measured CO PPM level, allowing more
accurate temperature detection.
Low Battery Life
Using the sleep mode or WDT features, the Z8
Encore! XP MCU can reduce your total power
consumption by waking your application,
quickly monitoring your results and powering
down-all a function of the low stand-by current
available on the MCU.
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.
