GENERAL DESCRIPTION
The ADuCM350 is a 16 MHz ARM® Cortex-M3 processor with
a high precision AFE specifically designed for high precision
data acquisition.
The ADuCM350 has a 16-bit precision analog core with four
dedicated voltage measurement channels and up to eight current
measurement channels. It has an integrated complex impedance
measurement system and uses an integrated parameterizable
waveform generator to generate complex waveforms. It uses an
excitation amplifier control loop to perform accurate potentiostat
type measurements and has a highly configurable switch matrix
that allows application specific amplifier configuration.
The device has a large array of peripherals, including USB,
CapTouch®, display, audio, and an array of serial interfaces
and GPIOs.
The ADuCM350 includes 384 kB of flash, 32 kB of SRAM, and
16 kB of flash configured as EEPROM.
The E VA L -ADuCM350EBZ kit provides scientists, system
analyzers, and software developers a platform to migrate from
sensor investigation and analysis to full ecosystem development.
The evaluation kit consists of an ADuCM350 motherboard and a
selection of analog front end and digital peripheral daughter boards.
The evaluation kit is designed specifically to work with the
ADuCM350 software development kit (SDK) and the evaluation
kit support package (EKSP)—both of which are available for
download on the ADuCM350 design resources page.
The software development kit is designed to work with the IAR
debugging environment only. The user guide for the ADuCM350
SDK is available on the SDK installer.
An example of where the kit is downloaded follows: C:\Analog
Devices\ADuCM350BBCZ\Eval-ADUCM350EBZ\doc
The SDK quick start guide and the EKSP user guide are available in
the Support Documentation zipped folder.

GETTING STARTED
SOFTWARE INSTALLATION PROCEDURES
For software installation procedures, refer to the following
ADuCM350 software documentation for further details:
•For more information about the EKSP LabVIEW® GUI,
refer to the EKSP user guide (ADuCM350_Evaluation_Kit_
Software_Platform.pdf) within the Documentation
folder of the software development kit.
•For more information about the SDK firmware/debug
environment, refer to SDK user guide (ADuCM350BBCZ_
Software_Users_Guide.pdf) within the Documentation
folder of the software development kit and to the ADuCM350
software development kit quick start guide, UG-677.
EVALUATION BOARD SETUP PROCEDURES
1. Plug the ADuCM350 switch mux configuration board into
the ADuCM350 evaluation board, E VA L-ADuCM350EBZ.
2. Plug the USB-SWD/UART-EMUZ board into J14 on the
ADuCM350 evaluation board, E VA L -ADuCM350EBZ.
3. Plug the USB cable into the USB-SWD/UART-EMUZ board.
After the drivers are downloaded, you can begin communicating
with the board.

EVALUATION BOARD CIRCUITRY
J-LINK OB EMULATOR
The J-Link OB emulator provides nonintrusive emulation via a
serial wire and allows supply and UART communication with
the ADuCM350 evaluation board (EVAL-ADuCM350EBZ).
Figure 4 shows a top view of the emulator board. The J2
connector plugs into the ADuCM350 evaluation board (EVAL-
ADuCM350EBZ). The J2 connector pinout is shown in Figure 5.
Figure 4. Emulator Top View
Figure 5. J2 Connector
For downloading and debugging, LK1, LK2, LK4, and LK6 must
be inserted. LK3 and LK5 are required to communicate via
UART. The required driver software for the J-Link OB can be
downloaded from the Segger website. Ensure that you also
install the virtual COM port drivers (see Figure 6).
