NuMicro™ NUC100 Data Sheet
5.14 Analog-to-Digital Converter (ADC)
5.14.1 Overview
NuMicro™ NUC100 Series contains one 12-bit successive approximation analog-to-digital
converters (SAR A/D converter) with 8 input channels. The A/D converter supports three
operation modes: single, single-cycle scan and continuous scan mode. The A/D converters can
be started by software and external STADC pin.
5.14.2 Features
z Analog input voltage range: 0~V_REF
z 12-bit resolution and 10-bit accuracy is guaranteed
z Up to 8 single-end analog input channels or 4 differential analog input channels
z Maximum ADC clock frequency is 16 MHz
z Up to 600K SPS conversion rate
z Three operating modes
„ Single mode: A/D conversion is performed one time on a specified channel
„ Single-cycle scan mode: A/D conversion is performed one cycle on all specified
channels with the sequence from the lowest numbered channel to the highest
numbered channel
„ Continuous scan mode: A/D converter continuously performs Single-cycle scan mode
until software stops A/D conversion
z An A/D conversion can be started by
„ Software write 1 to ADST bit
„ External pin STADC
z Conversion results are held in data registers for each channel with valid and overrun
indicators
z Conversion result can be compared with specify value and user can select whether to
generate an interrupt when conversion result is equal to the compare register setting
z Channel 7 supports 3 input sources: external analog voltage, internal bandgap voltage,
and internal temperature sensor output
z Support Self-calibration to minimize conversion error
