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).

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

E VA L -ADUCM420QSP1Z board.

Following this guide allows users to generate and download

their own user code to use in their own unique end system

requirements.

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.
