PREFACE
Thank you for purchasing the ADSP-21375 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for ADSP-21375 SHARC® processors.
The SHARC processors are based on a 32-bit super Harvard architecture
that includes a unique memory architecture comprised of two large
on-chip, dual-ported SRAM blocks coupled with a sophisticated IO processor, which gives a SHARC processor the bandwidth for sustained
high-speed computations. SHARC processors represents today’s de facto
standard for floating-point processing, targeted toward premium audio
applications.
The evaluation system is designed to be used in conjunction with the
VisualDSP++® development environment to test the capabilities of the
ADSP-21375 SHARC processors. The VisualDSP++ development environment gives you the ability to perform advanced application code
development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-21375 assembly
• Load, run, step, halt, and set breakpoints in application program
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory

The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2 Mbit of SPI flash memory. The flash memories can store user-specific
boot code, allowing the board to run as a stand-alone unit. For more
information, see “External Memory” on page 1-7 and “Boot Mode and
Clock Ratio Select Switch (SW2)” on page 2-9. The board has 16 MB of
SDRAM, which can be used at runtime or from which code can be
executed.
The DAI port of the processor connects to the AD1835A audio codec and
an external phase lock loop (PLL). The DAI interface facilitates development of digital and analog audio signal-processing applications. See
“Analog Audio” on page 1-10 and for more information.
The DPI port of the processor connects to the UART interface and the
SPI interface. The UART interface can connect to a standard RS-232 connection, while the SPI connects to the 2 Mbit of serial flash memory.
Additionally, the EZ-KIT Lite board provides access to all of the processor’s peripheral ports. Access is provided in the form of a three-connector
expansion interface. See “Expansion Interface” on page 2-7 for details.

Educational Laboratory Virtual Instrumentation Suite interface. The
interface features the DC voltage and current measurement modules,
oscilloscope and bode analyzer modules, function generator, arbitrary
waveform generator, and digital IO.
The ELVIS interface is a LabVIEW-based design and prototype environment for university science and engineering laboratories. The ELVIS
interface consists of LabVIEW-based virtual instruments, a multifunction
data acquisition (DAQ) device, and a custom-designed bench-top workstation and prototype board. This combination provides a ready-to-use
suite of instruments found in most educational laboratories. Because the
interface is based on LabVIEW and provides complete data acquisition
and prototyping capabilities, the system is ideal for academic coursework
that range from lower-division classes to advanced project-based
curriculums.

Analog Audio
Analog Audio
The AD1835A is a high-performance, single-chip codec featuring four stereo digital-to-analog converters (DACs) for audio output and one stereo
analog-to-digital converters (ADCs) for audio input. The codec can input
and output data with a sample rate of up to 96 kHz on all channels. A
192 kHz sample rate can be used with one of the DAC channels.
The processor is interfaced with the AD1835A via the DAI port. The DAI
interface pins can be configured to transfer serial data from the AD1835A
codec in either time-division multiplexed (TDM) or two-wire interface
mode (TWI). For more information on the AD1835A connection to the
DAI, see “DAI Interface” on page 2-4.
The master input clock (MCLK) for the AD1835A device can be generated
by the on-board 12.288 MHz oscillator or can be supplied by one of the
DAI pins of the processor. Using one of the pins to generate the MCLK, as
opposed to the on-board oscillator, allows synchronization of multiple
devices in the system. It is possible to disable the on-board audio oscillator
from driving the audio codec and the processor’s input pin. For instructions on how to configure the clock, refer to “Codec Setup Switch (SW3)”
on page 2-10.
The AD1835A codec can be configured as a master or as a slave, depending on the DIP switch settings. In master mode, the AD1835A drives the
serial port clock and frame sync signals to the processor. In slave mode,
the processor must generate and drive all of the serial port clock and frame
sync signals. For information on how to set up the mode, refer to “Codec
Setup Switch (SW3)” on page 2-10.
The internal configuration registers of the AD1835A codec are configured
using the SPI port of the processor. The DPI pin 4 (DPI4 register) is used
as the select for the device. For information on how to configure the multichannel codec, refer to the product datasheet at
http://www.analog.com/en/prod/0,2877,AD1835A,00.html.

The RCA connector (J10) is used to input analog audio. When using an
electret microphone on this connector, configure the SW4 switch according
to the instructions in “Electret Microphone Select Switch (SW4)” on
page 2-12. The four output channels connect to the RCA connector J5.
Channel 4 of the codec connects to the headphone jack J9. For more
information about the connectors see “Connectors” on page 2-21.
Example programs are included in the EZ-KIT Lite installation directory
to demonstrate how to configure and use the board’s analog audio
interface.
LEDs and Push Buttons
The EZ-KIT Lite has eight general-purpose user LEDs and four general-purpose push buttons.
Two of the general-purpose push buttons are attached to the FLAG pins of
the processor, while the other two are attached to the DAI pins. All of the
push buttons connect to the processor through a DIP switch. The DIP
switch allows processor pins, which connect to the push buttons, to be disconnected. See “Push Button Enable Switch (SW7)” on page 2-13 for
instructions on how to disable a push button from driving its corresponding processor pin.
The state of the push buttons, connected to the FLAG pins, can be determined by reading the FLAG register. The push buttons connected to the
DAI pins must be configured as interrupts. It is necessary to set up an
interrupt routine to determine each pin’s state. Table 1-2 shows the push
button and processor connections. Refer to the related example program
shipped with the EZ-KIT Lite for more information.

ADSP-21375 EZ-KIT Lite Hardware Reference
The CLKIN pin of the processor connects to a 16.384 MHz oscillator. The
core frequency of the processor is derived by multiplying the frequency at
the CLKIN pin by a value determined by the state of the processor pins
CLKCFG1 and CLKCFG0. The value at these pins is determined by the state of
the SW2 switch (see “Boot Mode and Clock Ratio Select Switch (SW2)” on
page 2-9). By default, the EZ-KIT Lite gives a core frequency of
262.144 MHz. It is possible to change the speed of the processor by
changing the value of the PMCTL register.
The SW2 switch also configures the boot mode of the processor. The
EZ-KIT Lite is capable of EPROM/flash boot and SPI boot. By default,
the EZ-KIT Lite boots from the flash memory. For information about
configuring the boot modes, see “Boot Mode and Clock Ratio Select
Switch (SW2)” on page 2-9.
External Port
The external port of the ADSP-21375 processor consists of a 24-bit
address bus, 16-bit data memory bus, and control lines. The control lines
are used to select, read, and write to external memory devices.
The external port connects to an 8-bit parallel flash memory and a 16-bit
SDRAM memory. See “External Memory” on page 1-7 for more information about accessing the flash and SDRAM memories.
All of the external port signals are available externally via the expansion
interface connectors (J1–3). The pinout of the connectors can be found in
“ADSP-21375 EZ-KIT Lite Schematic” on page B-1.

DAI Interface
The digital application interface (DAI) pins connect to the signal routing
unit (SRU) of the processor. The SRU is a flexible routing system, providing a large system of signal flows within the processor. In general, the SRU
allows to route the DAI pins to different internal peripherals in various
combinations.
The DAI pins connect to the AD1835A audio codec, a 26-pin header, two
RCA connectors, audio oscillator output, an external phase lock loop
(PLL) circuit, two LEDs, and two push buttons. Figure 2-2 illustrates the
EZ-KIT Lite’s connections to the DAI.

To use the DAI for a different purpose, disable any signal driving the DAI
pin with a switch (see “Codec Setup Switch (SW3)” on page 2-10). In
addition, the SW3 switch allows flexible routing of the 12.288 MHz audio
oscillator’s output signal. By default, this signal is used as the master clock
(MCLK) for the AD1835A codec.
All of the DAI signals are available externally via the expansion interface
connectors (J1–3), as well as the 0.1” spaced header P4. The pinout of the
connectors can be found in “ADSP-21375 EZ-KIT Lite Schematic” on
page B-1.
DPI Interface
The digital peripheral interface (DPI) pins connect to a second signal
routing unit of the processor (SRU2). The SRU2 unit, similar to the SRU, is a
flexible routing system, providing a large system of signal flows within the
processor. In general, the SRU2 allows to route the DPI pins to different
internal peripherals in various combinations.

effects of additional circuitry.
JTAG Emulation Port
The JTAG emulation port allows an emulator to access the internal and
external memory of the processor through a 6-pin interface. The JTAG
emulation port of the processor also connects to the USB debugging interface. When an emulator connects to the board at ZP4, the USB debugging
interface is disabled. This is not a standard connection of the JTAG
interface.
For information about the standard connection of the interface, see EE-68

ELVIS Oscilloscope Configuration Switch (SW1)
The oscilloscope configuration switch (SW1) determines which audio circuit signals connect to channels A and B of the oscilloscope. The switch is
used only when the board connects to the Educational Laboratory Virtual
Instrumentation Suite (ELVIS) station (see “ELVIS Interface” on
page 1-9). Each channel must have only one signal selected at a time, as
described in Table 2-7.

LEDs and Push Buttons
General Purpose LEDs (LED1–8)
There are eight general-purpose LEDs on the board. Five LEDs connect to
the DPI interface, two LEDs connect to the DAI interface, and one LED
connects to FLAG3 of the processor. “LEDs and Push Buttons” on
page 1-11 summarizes the LED connections. The respective registers of
the processor must be programmed appropriately in order to use LEDs
connected to the DAI or DPI. For more information on how to program
the registers, refer to the ADSP-21368 SHARC Processor Hardware Reference (includes ADSP-21375).
Power LED (LED9)
When LED9 is lit (green), it indicates that power is being supplied to the
board properly.
Reset LED (LED10)
When LED10 is lit (red), the master reset of all the major ICs is active.
USB Monitor LED (ZLED3)
The USB monitor LED (ZLED3) indicates that USB communication has
been initialized successfully, and you can connect to the processor using a
VisualDSP++ EZ-KIT Lite session. Once the USB cable is plugged into
the board, it takes approximately 15 seconds for the USB monitor LED to
light. If the LED does not light, try cycling power on the board and/or
reinstalling the USB driver (see the VisualDSP++ Installation Quick Reference Card).
VisualDSP++ is actively communicating with the EZ-KIT
L When
Lite target board, the LED can flicker, indicating communications
handshake.

ADSP-21375 EZ-KIT Lite Hardware Reference
Push Buttons (SW8–11)
Four push buttons (SW8–11) are provided for general-purpose user input:
two push buttons connect to the FLAG pins of the processor, while the
other two connect to the DAI of the processor. The push buttons are
active high and, when pressed, send a high (1) to the processor. Refer to
“LEDs and Push Buttons” on page 1-11 for more information. The push
button enable switch (SW7) is capable of disconnecting the push buttons
from the corresponding processor pins (refer to “Push Button Enable
Switch (SW7)” on page 2-13 for more information).
The push buttons and corresponding processor signals are summarized in
Table 2-9.

Board Reset Push Button (SW12)
The RESET push button (SW12) resets all of the ICs on the board. The only
exception is the USB interface chips. These chips are not being reset when
the push button is pressed after the USB cable has been plugged in and
communication correctly initialized with the PC. After USB communication has been initialized, the only way to reset the USB is by powering
down the board.

Figure 2-7. Jumper Locations
VCO Select Jumper (JP1)
The voltage-controlled oscillator (VCO) select jumper (JP1) configures
the frequency selection of the on-board external PLL (U39). When JP1 is
installed, the VCO output frequency is multiplied by a factor of 1.0. Conversely, when uninstalled, the VCO output frequency is multiplied by a
factor of 0.5 or divided in half. The jumper settings are shown in
Table 2-10.

ELVIS Voltage Selection Jumper (JP3)
The ELVIS voltage selection jumper (JP3) is used to select the power
source for the EZ-KIT Lite. In a standard mode of operation, the board
receives its power from an external power supply. When JP3 is installed,
the board is powered from an ELVIS station and no external power supply
is required. The jumper settings are shown in Table 2-12.

ELVIS Programmable Flag Jumper (JP4)
The ELVIS programmable flag jumper (JP4) connects the ADSP-21375
processor’s DAI4 pin to the ELVIS trigger pin. When JP4 is installed, DAI4
connects to the ELVIS TRIG1_2 pin directly. Conversely, when JP4 is
uninstalled, the DAIP4 pin is disconnected and can be used for another
non-ELVIS operation. The jumper settings are shown in Table 2-13.
