GENERAL DESCRIPTION
The ADuCM410 is a fully integrated, single package device that
incorporates high performance analog peripherals together with
digital peripherals. The ADuCM410 features 16-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 × 512 kB Flash/EE memory, packaged in a 5 mm × 5 mm, 81-ball
chip scale package ball grid array (CSP_BGA) and a 64-ball
wafer level chip scale package (WLCSP).
The ADuCM410 development system (EVAL-ADUCM410QSPZ
or EVAL-ADUCM410QSP1Z) is fully packaged to evaluate all
features of the ADuCM410, a high precision analog
microcontroller. The ADuCM410 includes 16 external AINx
channels, voltage output DACs (VDACs), four programmable
gain amplifiers (PGAs), measurement of the PGA current
channels, 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-ADUCM410QSPZ and EVAL-ADUCM410QSP1Z
board uses a low noise, low dropout (LDO) linear regulator to
power up the device. The ADuCM410 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 CSP_BGA
version (EVAL-ADUCM410QSPZ) and WLCSP version
(EVAL-ADUCM410QSP1Z) evaluation boards 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-ADUCM410QSPZ 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 ADucM410 are available in the
ADuCM410 data sheet, which must be consulted in conjunction
with this user guide when using the EVAL-ADUCM410QSPZ or
EVAL-ADUCM410QSP1Z board.

EVALUATION BOARD HARDWARE
POWER SUPPLIES AND DEFAULT LINK OPTIONS
The EVAL-ADUCM410QSPZ or EVAL-ADUCM410QSP1Z
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 EVAL-ADUCM410QSPZ or EVAL-
ADUCM410QSP1Z (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-ADUCM410QSPZ/EVAL-ADUCM410QSP1Z Board
Interface
The ADuCM410 has on-chip digital peripheral interfaces, such
as a universal asynchronic receiver/transmitter (UART), serial
peripheral interface (SPI), management data input/output
(MDIO), and I2C. See Figure 1 for the on-board component
locations.

The settings shown in the Project dropdown menu (see Figure 23)
are available on the Keil and IAR software tool environment. By
default, the floating-point unit (FPU) is disabled after the
settings are disabled. Code to enable and output the floating-
point value is added in the SystemInit function in the
system_ADuCM410.c file. This file is located in the example
program in the ADuCM410 installer folder named M410_FPU
(under the Files list in Figure 23).

SRAM MODE SETTINGS
Configuration settings are available on the Keil and IAR
software tool environments. To properly set up and test the
static random access memory (SRAM) modes, go to the
example projects located in the M410_SramMode installer.
IAR SRAM Mode
Three file settings must be completed to configure the
corresponding SRAM mode: main.c, startup_ADuCM410.s,
and ADuCM410flash_SramMode.icf.
1. After the example program is opened from the IAR IDE,
ensure that the macros shown in Figure 30 are set up and
commented in to select the SRAM mode the linker file is
operating in. The M410_SramMode example code (see
Figure 31) uses a linker file, the ADuCM410flash_
SramMode.icf file (see Figure 32) placed in the IAR folder
within the SramMode example program.
20323-016
Figure 30. IAR SRAM Setup main.c
5. Configure the macros shown in Figure 30, Figure 31, and
Figure 32 to run the SRAM modes. Ensure the main.c,
startup_ADuCM410.s, and
ADuCM410flash_SramMode.icf macros are selected with
the correct SRAM mode.
6. Users can select the desired USER_SRAM_MODE macro
as shown in Figure 31 and Figure 32. Users can also select
the TEST_SRAM_MODE macro as shown in Figure 30.
By default, the example program is running in TEST_SRAM_
MODE 0. Ensure the main.c macro, which runs the debug
mode, shows that the instruction SRAM (ISRAM) is placed
in debug mode. If the ISRAM is in debug mode, the
Disassembly window from the View menu bar displays the
isramTestFunc with the 0x10000000 address (see Figure 33).

Keil SRAM Mode
Several .sct and .s files from the example program allow users to
select the desired SRAM: M410_SramModeX.sct and
SetSramModeX.s. The X in the file name specifies mode
number (0 to 3) for the SRAM.
1. After the example program is opened from the Keil IDE, the
files located in the same folder are shown. Ensure that the
.sct and .s files from the example folder (see Figure 34) are
used with the corresponding SRAM mode being tested.
20323-020
Figure 34. SRAM Mode .sct and .s Files
7. By default, the M410_SramMode macro uses SRAM
Mode 0. The SetSramMode0.s assembly file is added to
the subdirectory shown in Figure 35. Specify which SRAM
mode to test in the main.c file. By default, SRAM Mode 0 is
tested (see Figure 36).
20323-021

8. After following Step 1 and Step 2, proceed to set up the .sct
file located in Flash > Configure Flash Tools > Linker. Refer
to Figure 37 to check the settings circled in green are
correct and that the correct scatter file is chosen (based on
the SRAM mode configuration).
9. Running the settings in Figure 38 shows that the ISRAM is
placed in debug mode via the Disassembly window.

SAFE CODE DEBUGGING/DEVELOPMENT RECOMMENDATIONS
The ADuCM410 code development and programming tools are
similar or identical to those used on other Analog Devices
microcontroller devices and to microcontrollers from other
companies. Care must be taken to ensure the device can be
reprogrammed to avoid lockup situations. In a lockup, the
connection to the ADuCM410 via programming/debug tools is
no longer possible.
This section lists scenarios that can cause lockup situations. If a
lockup situation occurs, recommendations are provided to
recover a device.
SCENARIOS THAT CAUSE DEVICE LOCKUPS
Page 0 Checksum Error
Address 0x1FFC contains a 32-bit checksum for Flash Page 0.
The on-chip kernel performs a checksum on Page 0 excluding
0x1FFC to 0x1FFF. If the kernel result does not match the value
at 0x1FFC or if 0x1FFC value is not 0xFFFFFFFF, the kernel
detects corruption of Page 0 and does not exit to user code,
resulting in a device lockup. See the ADuCM410 hardware
reference manual (UG-1807) for information about an integrity
check of the internal Flash Page 0 by the on-chip kernel.
To recover from this situation, mass erase the device via the
downloader tool (I2C or MDIO), and ensure the user source
code sets Flash Address 0x01FFC = 0xFFFFFFFF.
The example code for the ADuCM410 configures Flash Address
0x01FFC = 0xFFFFFFFF.
See page0_checksum in the system_ADuCM410.c file.
User Flash Pages—Corruption of Reserved Locations
The top six 32-bit locations of each flash block are reserved, and
care must be taken not to overwrite these locations. The flash
signature for each block and the write protection settings are
stored in these six locations. See the ADuCM410 Hardware
Reference Manual for information about flash user space
organization.
Ensure the top 32-bit location in each flash page is reserved.
See the example programs included in the installer for details.
Unexpected Resets
Unexpected watchdog resets, software resets, power-on resets,
or external resets can cause debug/programming sessions to
end abruptly because these resets break the SWD interface
between the J-Link and the Cortex core.
If the user source code results in regular resets, try mass erasing
the user flash via the downloader and restart the debug session.
Power Saving Modes
If the user code puts the Cortex core into a power-down state,
the power-down causes issues after a power cycle for the debug
tools that use the SWD interface. Tools like J-Link require the
Cortex core to be fully active.
Keil CMSIS Pack
For Keil μVision users only, ensure Keil CMSIS pack
Version 1.4.0 or later is being used.
RECOVERING LOCKED UP DEVICES
Mass erase the device via either the MDIO or I2C downloader
tool.

PROGRAMMABLE LOGIC ARRAY (PLA) TOOL
The ADuCM410 integrates a PLA that consists of two
independent but interconnected PLA blocks. Each block
consists of 16 elements, giving a total of 32 elements listed from
Element 0 to Element 31. The PLA tool is a graphical tool that
allows easy configuration of the PLA. The PLA tool can be
found on the ADuCM410 installer, under the Tools folder. With
the PLA tool, the correct output value is determined after all the
options from the tool is properly selected.
CONFIGURING THE GATES AND OUTPUT
PLA elements contains a two-input lookup table that can be
configured to generate logic output function based on the two
inputs and flip flop in the PLA, as shown in Figure 39. Each
PLA element in a block can be connected to other elements in
the same block by configuring the output of Mux 0 and Mux 1.
The user can select respective inputs that correspond to the
PLA_ELEMx register bits. See the ADuCM410 Hardware
Reference Manual for a complete list of possible connections for
the element GPIO input/output, and for the lookup table
configuration in the PLA.
After the inputs are selected from the GUI, ensure that the
BLOCK, ELEMENT, and LOOK UP TABLE options are
selected in the top right portion of the tool. Click the ENTER
button to generate the output of PLA (see Figure 39).
