Analog-to-Digital Converter
The Z8FMC16100 Series Flash MCU includes an eight-channel analog-to-digital con-
verter (ADC). The ADC converts an analog input signal to a 10-bit binary number. The
features of the successive-approximation ADC include:
• Eight analog input sources multiplexed with general-purpose I/O ports
• Fast conversion time, less than 5µs
• Programmable timing controls
• Interrupt upon conversion complete
• Internal voltage reference generator
• Internal reference voltage available externally
• Ability to supply external reference voltage
• Timer count capture on every ADC conversion
Architecture
The ADC architecture, as shown in Figure 36, consists of an 8-input multiplexer, sample-
and-hold amplifier, and 10-bit successive-approximation analog-to-digital converter. The
ADC digitizes the signal on a selected channel and stores the digitized data in the ADC
data registers. In environments with high electrical noise, an external RC filter must be
added at the input pins to reduce high-frequency noise.
