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.
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 1.5V, VDD_INT 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

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 out-
put 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.
Automotive Audio Bus A2B Transceiver (AD2410)
The Automotive Audio Bus (A2B™) provides a multi-channel, I2S/TDM link over distances of up to 10 meters
between nodes. It embeds bi-directional synchronous data (for example digital audio), clock and synchronization
signals onto a single differential wire pair. A2B supports a direct point-to-point connection and allows multiple, dai-
sy chained nodes at different locations to contribute or consume time division multiplexed channel content. A2B is a
single-master, multiple-slave system where the transceiver chip at the host controller is the master. It generates clock,
synchronization and framing for all slave nodes. The master A2B chip is programmable over a control bus (I2C) for
configuration and read back. An extension of this control bus is embedded in the A2B data stream allowing direct
access of registers and status information on slave transceivers as well as I2C-to-I2C communication over distance.
12 Channel, High Performance, 192kHz, 24-Bit DAC
(ADAU1962A)
The ADAU1962A is a high performance, single-chip digital-to-analog converter (DAC) that provides 12 DACs
with differential or single-ended output using the Analog Devices, Inc., patented multibit sigma-delta (Σ-Δ) archi-
tecture. A serial peripheral interface (SPI)/I2C port is included, allowing a micro-controller to adjust volume and
many other parameters. The ADAU1962A operates from 2.5 V digital and 3.3 V analog supplies. A linear regulator
is included to generate the digital supply voltage from the analog supply voltage.
The ADAU1962A is designed for low EMI. This consideration is apparent in both the system and circuit design
architectures. By using the on-board PLL to derive the internal master clock from an external LRCLK, the
ADAU1962A can eliminate the need for a separate high frequency master clock and can be used with or without a
bit clock. The DACs are designed using the latest Analog Devices continuous time architectures to further minimize
EMI.
Quad ADC with Diagnostics (ADAU1977)
The ADAU1977 incorporates four high performance analog-todigital converters (ADCs) with direct-coupled inputs
capable of 10 V rms. The ADC uses multibit sigma-delta (Σ-Δ) architecture with continuous time front end for low

EMI. The ADCs can be connected to the electret microphone (ECM) directly and provide the bias for powering the
microphone. Built-in diagnostic circuitry detects faults on input lines and includes comprehensive diagnostics for
faults on microphone inputs. The faults reported are short to battery, short to microphone bias, short to ground,
short between positive and negative input pins, and open input terminals. In addition, each diagnostic fault is availa-
ble as an IRQ flag for ease in system design. An I2C/SPI control port is also included. The ADAU1977 uses only a
single 3.3 V supply. The part internally generates the microphone bias voltage. The microphone bias is programma-
ble in a few steps from 5 V to 9 V. The low power architecture reduces the power consumption. An on-chip PLL
can derive the master clock from an external clock input or frame clock (sample rate clock). When fed with a frame
clock, the PLL eliminates the need for a separate high frequency master clock in the system.
Quad Analog-to-Digital Converter (ADAU1979)
The ADAU1979 incorporates four high performance, analog-to-digital converters (ADCs) with 4.5 V rms capable
ac-coupled inputs. The ADCs use a multibit sigma-delta (Σ-Δ) architecture with continuous time front end for low
EMI. An I2C/serial peripheral interface (SPI) control port is included that allows a microcontroller to adjust volume
and many other parameters. The ADAU1979 uses only a single 3.3 V supply. The device internally generates the
required digital DVDD supply. The low power architecture reduces the power consumption. The on-chip PLL can
derive the master clock from an external clock input or frame clock (sample rate clock). When fed with the frame
clock, it eliminates the need for a separate high frequency master clock in the system.
