6.11.1 Overview
6.11.2 Features
6.11 Analog-to-Digital Converter (ADC)
NuMicro M051
NuMicro M051
(SAR A/D converter) with 8 input channels. The A/D converter supports four operation modes:
single, burst, single-cycle scan and continuous scan mode. The A/D converters can be started by
software and external STADC/P3.2 pin.
Analog input voltage range: 0~AVDD (Max to 5.0V).
12-bit resolution and 10-bit accuracy is guaranteed.
Up to 8 single-end analog input channels or 4 differential analog input channels.
Maximum ADC clock frequency is 16 MHz.
Up to 600k SPS conversion rate.
Four operating modes
An A/D conversion can be started by

-
Conversion results are held in data registers for each channel with valid and overrun
indicators.
Conversion result can be compared with specify value and user can select whether to
generate an interrupt when conversion result matches the compare register setting.
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.
Burst mode: A/D conversion will sample and convert the specified single channel and
sequentially store in FIFO.
