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 follows: • 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 circuits (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. 2–6 ADSP-CM419F EZ-KIT ® Manual Power Architecture 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 supplies 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 resistors 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 precision 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 resistor. 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 installation 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: http://www.analog.com/ADSPCM419FEZKIT . ADSP-CM419F EZ-KIT ® Manual 2–7 32M-bit Serial Flash Memory with Dual and Quad SPI (W25Q32) 32M-bit Serial Flash Memory with Dual and Quad SPI (W25Q32) The W25Q32BV (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 W25Q32BV 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 W25Q32BV 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 W25Q32BV 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 Continous 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.

The ADM3053 complies with the ISO 11898 standard. The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator, a CAN transceiver, and Analog Devices isoPower® dc-to-dc converter into a single SOIC surface mount package. An on-chip oscillator outputs a pair of square waveforms that drive an internal transformer to provide isolated power. The device is powered by a single 5 V supply realizing a fully isolated CAN solution. The ADM3053 creates a fully isolated interface between the CAN protocol controller and the physical layer bus. It is capable of running at data rates of up to 1 Mbps. The device has current limiting and thermal shutdown features to protect against output short circuits. The part is fully specified over the industrial temperature range and is available in a 20-lead, wide-body SOIC package. The ADM3053 contains isoPower technology that uses high frequency switching elements to transfer power through the transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards.
