Regulatory Compliance
The CPA(Control Processor Assembly) is designed to be used solely in a laboratory environment. The board is not
intended 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 CPABoardcontains 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 degradation or
loss of functionality. Store unused boards in the protective shipping package.

1Preface
Thank you for purchasing the Analog Devices, Inc. CPA development Board evaluation system.
The ADSP-CM419F processor is based on the ARM® Cortex®-M4 processor core with floating point unit
operating at frequencies up to 240 MHz core clock, and the ARM® Cortex-M0 TM processor core operating at
frequencies up to 100 MHz system clock. The processors integrate up to 192K Bytes of SRAM memory with ECC,
up to 1M Byte of flash memory 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 CPA board ships with all of the
necessary hardware to get you up and running and start the evaluation immediately.
The CPA contains an analog interface and digital interface. The evaluation board is designed to be used in
conjunction with the IAR Embedded Workbench®and Segger® development environment for advanced application

Power Architecture
Digital Supply
The ADSP-CM419F has two primary voltage domains: 3.3V and 5.0V. The 5.0V source can be selected to input
from the USB connector (J200) or from the connector interface (X401). The Analog Devices ADM7170ACPZ
provides 3.3V to the analog circuitry while the ADP2119 provides 3.3V to the digital circuitry.
Analog Front End
The Analog Front End is powered via 3.3V_ANA power supplies which fall in 3.3V domain. There are two main
connectors on the Boards X400 and X401, where the analog ADC channels are available on the X401 external
connector. See below the connections for the ADC inputs on X401.

64M-bit Serial Flash Memory with Dual and Quad SPI
(W25Q64)
The W25Q64FV (32 Mb) Serial Flash memory provides a storage solution for systems with limited space, pins and
power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal
for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data.
The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 4 mA active and 1
uA for power-down.
The W25Q64FV array is organized into 16,384 programmable pages of 256 bytes each. Up to 256 bytes can be
programmed at a time. Pages can be erased in a group of 16 (4 KB sector erase), groups of 128 (32 KB block erase),
groups of 256 (64 KB block erase) or the entire chip (chip erase). The W25Q64FV has 1024 erasable sectors and 64
erase blocks respectively. The small 4 KB sectors allow for greater flexibility in applications that require data and
parameter storage.
The W25Q64FV supports the standard Serial Peripheral Interface (SPI), and a high performance Dual/Quad ouput
as well as Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (WP), and I/O3
(/HOLD). SPI clock frequencies of up to 104 MHz are supported, providing equivalent clock rates of 208 MHz
(104 MHz x 2) for Dual I/O and 320 MHz (80 MHz x 4) for Quad I/O when using Fast Read Dual/Quad I/O
instructions. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. The
Continuous Read Mode allows for efficient memory access with as few as 8-clocks of instruction-overhead to read a
24-bit address, allowing true XIP (execute in place) operation.
USB to UART (FT232R)
The FT232R is a USB-to-serial-UART interface with the following advanced features:
•Single chip USB to asynchronous serial data transfer interface
•Entire USB protocol handled on the chip. No USB specific firmware programming required
•Fully-integrated 1024 bit EEPROM storing device descriptors and CBUS I/O configuration
•Fully-integrated USB termination resistors
•Fully-integrated clock generation with no external crystal required, plus optional clock output selection
enabling a glue-less interface to the controller
• Data transfer rates from 300 baud to 3Mbaud (RS422, RS485, RS232) at TTL levels
•128 byte receive buffer and 256 byte transmit buffer utilizing buffer smoothing technology to allow for high-
data throughput
•FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB
driver development in most cases.
•Transmit and receive LED drive signals

16
•UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity
•FIFO receives and transmits buffers for high-data throughput
•Device supplied pre-programmed with unique USB serial number
•Supports bus powered, self-powered and high-power bus powered USB configurations
•Integrated +3.3V level converter for USB I/O
•Integrated level converter on UART and CBUS for interfacing to between +1.8V and +5V logic
•True 5V/3.3V/2.8V/1.8V CMOS drive output and TTL input
•Configurable I/O pin output drive strength
•Integrated power-on-reset circuit
•Fully-integrated AVCC supply filtering - no external filtering required.
•UART signal inversion option
•+3.3V (using external oscillator) to +5.25V (internal oscillator) single supply operation
•Low-operating and USB suspend current
•Low USB bandwidth consumption
•UHCI/OHCI/EHCI host controller compatible
•USB 2.0 full speed compatible
Dual channel Digital Isolator –5K RMS (ADuM2281)
The ADuM2280/ADuM2281/ADuM2285/ADuM2286ADuM228x in this data sheet) are 5 kV rms dual-channel
digital isolators based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and
monolithic air core transformer technology, these isolation components provide outstanding performance
characteristics superior to alternatives, such as optocoupler devices and other integrated couplers.
With propagation delay at 24 ns maximum, pulse width distortion is less than 2 ns for C grade. Channel-to-channel
matching is tight at 5 ns for C grade. The ADuM228x are available in two channel configurations with three
different data rates up to 100 Mbps (see the Ordering Guide). All models operate with the supply voltage on either
side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage
translation functionality across the isolation barrier. Unlike other optocoupler alternatives, the ADuM228x isolators
have a patented refresh feature that ensures dc correctness in the absence of input logic transitions. When power is
first applied or is not yet applied to the input side, the ADuM2280 and ADuM2281 have a default high output and
the ADuM2285 and ADuM2286 have a default low output.

5 kV digital Isolator with 5V DC-to-DC (ADUM6201)
The ADuM6200/ADuM6201/ADuM62021 are dual-channel digital isolators with isoPower®, an integrated, isolated
dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides up to
400 mW of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or at 3.3 V from a 3.3 V
supply at the power levels shown in Table 1. These devices eliminate the need for a separate, isolated dc-to-dc
converter in low power, isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic
signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation
solution. The ADuM6200/ADuM6201/ADuM6202 isolators provide two independent isolation channels in a
variety of channel configurations and data rates (see the Ordering Guide for more information). isoPower uses high
frequency switching elements to transfer power through its transformer. Special care must be taken during printed
circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout
recommendations
