GENERAL DESCRIPTION

The ADuCM420 is a fully integrated, single package device that
incorporates high performance analog peripherals together with
digital peripherals. The ADuCM420 features 12-bit, 2 MSPS data
acquisition on up to 16 input pins, an Arm® Cortex®-M33
processor, 12 voltage digital-to-analog converters (DACs), and
2× 256 kB Flash/EE memories, packaged in a 64-ball wafer level
chip scale package (WLCSP).
PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS.
EVAL-ADUCM420QSP1Z
The ADuCM420 development system (EVAL-ADUCM420QSP1Z)
is fully packaged to evaluate all features of the ADuCM420, a
high precision analog microcontroller. The ADuCM420
includes 12 external AINx channels, voltage output DACs
(VDACs) and various shared functions with the general-purpose
input/outputs (GPIOs) that are configurable through registers.
The VDAC channels generate an output range up to 2.5 V or
3.3 V full scale.
The EVAL-ADUCM420QSP1Z board uses a low noise, low
dropout (LDO) linear regulator to power up the device. The
ADuCM420 is powered up using the following three options: a
9 V wall wart adapter, a 5 V external supply terminal block, and
a USB supply.
This user guide describes how to configure the EVAL-
ADUCM420QSP1Z evaluation board by providing step by step
procedures about the connections on the evaluation boards.
This user guide also contains information regarding which
evaluation versions of the third-party software tools to download.
Additionally, this user guide provides instructions on how to load
the supplied code examples. See Figure 1 for a photograph of the
EVAL-ADUCM420QSP1Z board.
Following this guide allows users to generate and download
their own user code to use in their own unique end system
requirements.
Complete specifications for the ADucM420 are available in the
ADuCM420
data sheet, which must be consulted in conjunction
with this user guide when using the EVAL-ADUCM420QSP1Z
board.
