Using the EVAL-ADUSB2EBZ
by Brett Gildersleeve
The ribbon cable and 10-pin header form a bridge to the target
board to connect the communications signals to the target IC.
The ribbon cable also carries 5 V power from the USB hub, which
can be used to power the target board if desired.
INTRODUCTION
The EVAL-ADUSB2EBZ features USB-to-I2C and SPI conversion.
It is compatible with 1.8 V and 3.3 V target devices and allows
for SigmaStudio™ integration for most SigmaDSP® processors.
Its on-board power regulators are capable of supplying the
target board, and it features a standard Aardvark-compatible
programming header. The EVAL-UDSUB2EBZ provides SPI
control of up to five slave devices with a low profile surfacemount USB miniature Type B connector, and it allows for plugand-play operation.
The on-board regulators enable both 1.8 V and 3.3 V IOVDD
operation, allowing for increased compatibility with target
devices.
Up to five slave devices can be controlled by the USBi simultaneously. To control multiple SPI devices, additional latch signals
are provided, although they are not connected to the ribbon cable.
The EVAL-ADUSB2EBZ is ideal for downloading code
and register settings to SigmaDSP processors and codecs
with SigmaStudio. It can also be used for real-time tuning
of SigmaDSP production units with SigmaStudio.
The USBi can be used to control SigmaDSP systems in real time
via SigmaStudio, and is capable of programming an EEPROM
in self-boot systems. It is an ideal solution for in-circuit programming and tuning of prototype systems.
GENERAL DESCRIPTION
The USBi only supports USB 2.0 interfaces; the USBi will not
work with PCs that only support USB Version 1.0 and USB
Version 1.1.
The EVAL-ADUSB2EBZ, also known as the USBi, is a standalone
communications interface and programmer for SigmaDSPsystems.
It translates USB control commands from SigmaStudio to the I2C
and SPI communications protocols. The USBi is powered over
the USB cable; therefore, no external power supply is required.

MONITORING THE USBi
WARNING
Using the Capture Window, it is possible to view all outgoing
communications transfers from the PC to the target IC. For
each write, the write mode, time of write, cell name (if applicable), parameter name, address, value, data (in decimal and
hexadecimal), and byte length are shown.
The USBi has an EEPROM on the I2C bus at Address 0x51, which
it uses to indicate its Vendor ID and Product ID to the PC, as
well as boot its internal program. You should avoid having any
other EEPROMs in your system design at this address. This
EEPROM is not write-protected; therefore, if you attempt to
write to Address 0x51, you will overwrite the USBi's onboard
EEPROM, and the USBi will cease to function. The USBi cannot be
reprogrammed without returning the board to Analog Devices.
Most EEPROMs are set to Address 0x51 by setting its pins A0 = 1
and A1 = A2 = 0.
For block writes where more than one memory location is
written, only the first location is shown. The expand/collapse
button in the leftmost column allows the user to view the full
data write.
USING THE USBi TO PROGRAM A SELF-BOOT
EEPROM
08093-017
After compiling a project, the registers and RAM contents
can be written to a target EEPROM for self-boot. To use this
functionality, an EEPROM IC must be connected to the USBi
in the Hardware Configuration window. After verifying that
the EEPROM write protect pin is disabled on the target board,
right-click the target IC (SigmaDSP), and select Write Latest
Compilation to E2PROM.

CIRCUIT SCHEMATICS
USB CONNECTOR
POWER REGULATOR
The connection between the host PC and the Cypress USB
interface device is via a standard USB cable that carries D+ and
D− signals for data communications, a 5 V power supply, and
ground. The D+ and D− lines are a one-wire communication
interface carried by half-duplex differential signals on a twisted
pair. The clock is embedded in the data using the nonreturn-tozero inverted (NRZI) line code. These signal lines connect
directly to pins on the Cypress USB interface.
The Cypress USB Interface I/O ports are capable of operating in
both 1.8 V and 3.3 V modes, depending on the target device in
the system. Two regulators, one for 5 V to 3.3 V regulation and
the other for 5 V to 1.8 V regulation, run simultaneously when
the board is powered. A switch (S1) is provided to easily switch
the IOVDD supply between the two regulators. LED D4 provides
visual feedback that the board is being supplied with 5 V power
from the PC USB port.
A surface-mounted USB miniature Type B jack was selected for
its low profile and increasing ubiquity in consumer electronics.
The position of switch S1 should not be changed when the
board is connected to the USB bus.
