Regulatory Compliance
The ADSP-CM419F EZ-KIT ®is designed to be used solely in a laboratory environment. The board is not inten-
ded for use as a consumer-end product or as a portion of a consumer-end product. The board is an open system
design, which does not include a shielded enclosure and, therefore, may cause interference to other electrical devices
in close proximity. This board should not be used in or near any medical equipment or RF devices.
The ADSP-CM419F EZ-KIT ®is in the process of being certified to comply with the essential requirements of the
European EMC directive 2004/108/EC and, therefore, carries the “CE” mark.
ADSP-CM419F EZ-KIT ®Manual i

The ADSP-CM419F EZ-KIT ®contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily
accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur
on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance deg-
radation or loss of functionality. Store unused boards in the protective shiping package.

1 Preface
Thank you for purchasing the Analog Devices, Inc. ADSP-CM419F EZ-KIT ®evaluation system.
The ADSP-CM419F processor is based on the ARM®Cortex®-M4 prprocessor core with floatingpoint unit operat-
ing at frequencies up to 240 MHz, and the ARM® Cortex-M0TM processor core operating at frequencies up to
100 MHz. The processors integrate up to 160K Bytes of SRAM memory with ECC, up to 1M Byte of flash memo-
ry with ECC, accelerators and peripherals optimized for motor control and photo-voltaic (PV) inverter control, and
an analog front end consisting of up to two 6 times simultaneous sampling 16-bit SAR-type ADCs, one 14-bit SAR
monitor ADC and one 12-bit DAC. The EZ-KIT ships with all of the necessary hardware to get you up and run-
ning and start the evaluation immediately.
The EZ-KIT contains an analog interface and PWM/digital interface. These interfaces are provided for connecting
with daughter boards to expand on the functionality of the EZ-KIT.
The evaluation board is designed to be used in conjunction with the IAR Embedded Workbench®and Segger®
development environment for advanced application code development and debug such as:
•Create, compile, assemble, and link application programs written in C++, C, and assembly
•Load, run, step, halt, and set breakpoints in application programs

8. Choose Project > Debug and Download to download the project and start debugging.
Debug Interface
The EZ-KIT provides a JTAG/SWD/SWO connection via .
Power-On-Self Test
The Power-On-Self-Test Program (POST) tests all EZ-KIT peripherals and validates functionality as well as connec-
tivity to the processor. Once assembled, each EZ-KIT is fully tested for an extended period of time with POST. All
EZ-KITs boards are shipped with POST preloaded into flash memory. The POST is executed by resetting the board
and pressing the proper push button(s). The POST also can be used as a reference for a custom software design or
hardware troubleshooting.
Note that the source code for the POST program is included in the Board Support Package (BSP) along with the
readme.txt file that describes how the board is configured to run POST.
Analog Input Channel Selection
The ADSP-CM419F EZ-KIT ®has 24 Primary ADC Input Channels & 7 Secondary ADC Input Channels as fol-
lows:
•Primary
•A0 - A7
•B0 - B7
•C0 - C7
•Secondary
•D0 - D7
Multiple input options are available for the ADC Inputs. These include:
•Expansion Interface
•On-board precision DAC
•Op-amp based conditionint of signals via SMC connector
There are 6 SMC connectors on board (J10, J11, J12, J13, J15, J16) that connects to the signal conditioning cir-
cuits (DUTs). Each Input can select between two such DUTs.
The inputs can also select between expansion interface or the DAC output. Note that DAC output is not available
on all channels. By default, all inputs (except A0) are connected to the expansion interface via resistors that need to
be installed. The input channel A0 is provided with jumpers on all four selections.
Debug Interface

Power Architecture
Digital Supply
The ADSP-CM419F EZ-KIT ®has two primary voltage domains: 3.3V and 1.2V. The main input is a 5V wall
adaptor. The 5V source can be selected via JP44 to input from the PWM connector (J4) as an alternative to the
wall power adaptor. Refer to J4 and JP44 for details. The Analog Devices ADM7172 LDO provides 3.3V for the
VDD_EXT signal and the 3.3V power requirements of the board. The VDD_INT signal is delivered through either
Analog Devices regulator ADP1715 Linear Regulator (VR2) or a PNP transistor (Q1). Jumper JP2 is provided to
select between External and Internal regulator.
Analog Front End
The Analog Front End is powered via VDD_ANA0 and VDD_ANA1 power pins which fall in 3.3V domain. The
Fast Over Current Protection (FOCP) Comparators are powered via VDD_COMP. By default, analog supplies are
powered from the ADM7172 LDO which powers up the VDD_EXT and rest of the 3.3V domain. External sup-
plies can power up the analog domain via P6, P7 & P8. A +/-5V supply (via P11) is required for the Op Amps at
the input of the Analog Input Channels. A +/-15V supply is required for the DAC AD5791.
Power Measurements
Locations are provided for measuring the current draw from various power planes. Precision 0.051 ohm shunt resis-
tors are available on the 3.3V and VDD_EXT voltage domains. For current draw, the jumper is removed, voltage
across the resistor can be measured using an oscilloscope, and the value of the resistor can be measured using a preci-
sion multi-meter. Once voltage and resistance are measured, the current can be calculated by dividing the voltage by
the resistance. For the highest accuracy, a differential probe should be used for measuring the voltage across the resis-
tor.
Example Programs
Example programs are provided with the ADSP-CM419F EZ-KIT ®Board Support Package (BSP) to demonstrate
various capabilities of the product. The programs can be found in the ADSP-CM419F_EZ-KIT\examples installa-
tion folder. Refer to a readme file provided with each example for more information.
Reference Design Information
A reference design info package is available for download on the Analog Devices Web site. The package provides
information on the schematic design, layout, fabrication, and assembly of the board.
The information can be found at:
