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).
The ADuCM420 development system (E VA L -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 E VA L -
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

EVALUATION BOARD HARDWARE
POWER SUPPLIES AND DEFAULT LINK OPTIONS
The EVAL -ADUCM420QSP1Z development system can be
powered with the following options: a 5 V terminal block from
bench supplies, a 9 V wall mounted adapter, or a USB supply.
See Table 1 for the on-board jumper configurations for each
power supply option and other optional connectors. Locate
Pin 1 for each header pin for the supply.
For any of the power supply options, place the jumpers shown
in Table 1 in the required operating setup before supplying
power to the EVA L -ADUCM420QSP1Z (see Figure 2).
Each power supply is decoupled to the relevant ground plane
with 10 µF and 0.1 µF capacitors. Each device supply pin is also
decoupled with a 10 µF and 0.1 µF capacitor pair to the relevant
ground plane.
EVAL-ADUCM420QSP1Z Board Interface
The ADuCM420 has on-chip digital peripheral interfaces, such
as a universal asynchronous receiver/transmitter (UART), serial
peripheral interface (SPI), management data input/output
(MDIO), and I2C. See Figure 1 for the on-board component
locations.
Bench Power Supply Option
The ADuCM420 requires 5 V for normal operation. Replicating
the jumper configuration in Table 1, the 5 V terminal block
supply passes through LDO regulators to regulate the power
supply. The ADuCM420 can also configure the IOVDD1 and
DVDD power supplies to be 1.2 V or 1.8 V, and 1.8 V or 3.3 V,
respectively. To conf igure these supply options, select the
required position on Jumper P11 for IOVDD1 and Jumper P15
for DVDD. P11 and P15 are on the solder side (bottom side of
the evaluation board.)

ARDUINO CONNECTOR
The EVAL -ADUCM420QSP1Z has Arduino R3 headers
directly compatible with Arduino Uno and Arduino Zero. The
Arduino pins used by the E VA L -ADUCM420QSP1Z board are
given in Table 3.
For more information on the ADuCM420 pins, refer to the
ADuCM420 data sheet and ADuCM420 hardware reference
manual (UG-1807).
By default, the EVAL-ADuCM420QSP1Z board is configured as
an Arduino slave board, with connectors populated only on the
component side of the PCB.
If the EVAL-ADuCM420QSP1Z board is to be configured as an
Arduino host, populate a different connector type on the solder
side with the following guidelines:
•P16 and P19: 8-pin, single-row headers, 2.54 mm pitch (for
example, the Samtec SSQ-108-03-G-S)
•P21: 6-pin, single-row header, 2.54 mm pitch (for example,
the Samtec SSQ-106-03-G-S)
•P13: 10-pin, single-row headers, 2.54 mm pitch (for
example, the Samtec SSQ-110-03-G-S)
Figure 3 shows the appropriate connector type. For proper slave
adapter connection, ensure the female part is on the solder side
with the long pins protruding through to the component side.
