SPI Flash


SPI FlashThe ADSP-BF706 processor has three SPI interfaces: SPI0, SPI1, and SPI2. SPI2 is connected to a Winbond W25Q32BC 32 Mb serial flash memory with dual and quad SPI support. This flash is used for booting and scratchpad space. The boot mode of the ADSP-BF706 EZ-KIT Mini is SPI master, which is set by resistors on the board.

For more information, refer to the SPI flash example in the POST, which is included in the ADSP-BF706 EZ-KIT Mini Board Support Package.

Audio CodecThe ADAU1761 (U2) is a SigmaDSP® low power, stereo audio codec (24 bits) connected to the ADSP-BF706 EZ-KIT Mini through TWI and SPORT0 interfaces. Line-in is provided through a 3.5 mm audio jack (J1) and headphone connected to a 3.5 mm jack (J2). When cables are inserted, the loopback from J2 to J1 is disconnected.

Connector P7 allows connection to the unused microphone and line-out functionality of the audio codec.

Refer to ADSP-BF706 EZ-KIT Mini Schematic for more information.

USB InterfaceThe ADSP-BF706 processor has an integrated USB PHY; the EZ-KIT Mini provides a micro-AB connector (P8).

See Power Architecture for information on powering an external USB device.



ADSP-BF706 EZ-KIT Mini for Arduino Uno R3 Connectivity

The ADSP-BF706 EZ-KIT Mini supports shield use through connectors P2, P3, P5, and P6, allowing compatibility with the Arduino Uno R3 boards. The connectors are not provided, but can be purchased online. The connectors are standard 0.1" stackable headers that allow for more than one shield to be attached. Signal output from the Arduino Uno R3 board is buffered on the ADSP-BF706 EZ-KIT Mini to ensure that the voltage level is tolerant with the ADSP-BF706 processor. Output signals from the ADSP-BF706 processor drive at 3.3V to connectors P2, P3, and P5. See ADSP-BF706 EZ-KIT Mini Schematic for more details.

External Connection PointsConnectors P1, P4, and P9 allow a user to attach wires to processor signals for interfaces such as EPPI, SPORT, TWI, TMR and GPIO of the ADSP-BF706 processor.

Debug InterfaceThe EZ-KIT Mini has an on-board debug agent which provides software development with one piece of hardware.

Power-On-Self Test


Power-On-Self TestThe Power-On-Self-Test Program (POST) tests all EZ-KIT Mini periph-erals and validates functionality as well as connectivity to the processor. Once assembled, each EZ-KIT Mini is fully tested for an extended period of time with POST. All EZ-KIT Mini boards are shipped with POST pre-loaded 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 ADSP-BF706 EZ-KIT Mini Board Support Package along with the readme.html file that describes how the board is configured to run POST.

Power ArchitectureThe ADSP-BF706 EZ-KIT Mini has two methods to power the board—through the debug agent’s USB mini connector (ZP1) or through the micro USB connector (P8) attached to the ADSP-BF706 processor.

By selecting the jumper positioning on JP2, the power source can be swapped between the two. Only change the JP2 jumper setting when both USB cables are removed.

• Method 1. To configure the board to use the 5V power from the debug agent’s USB mini connector, set JP2 to positions 1 and 2 (labeled DA).

• Method 2. To configure the board to use power from the USB micro connector, set JP2 to positions 2 and 3 (labeled 706).

The debug agent can be powered separately, even with the JP2 setting of the 706 as the power source (jumper on positions 2 and 3), by inserting a USB cable connected to a PC in both the micro and mini USB connector.



If the ADSP-BF706 EZ-KIT Mini is acting as a USB host through con-nector P8 and needs to supply power to a bus-powered device, install P13 to allow the appropriate bulk capacitance.

The voltage domains of the ADSP-BF706 EZ-KIT Mini are 3.3V (VDD_EXT, 3V_SLEEP) and 1.1V (VDD_INT). These voltage domains are provided by VR1, VR2, and VR3.

A FET switch (U10) controls the 5V to the USB devices over the USB0_VBUS signal.

Power MeasurementsLocations are provided for measuring the current draw from various power planes. Precision 0.051 ohm shunt resistors are available on the VDD_INT and VDD_EXT voltage domains. To measure current draw, the correspond-ing jumper is removed, voltage across the resistor is measured using an oscilloscope, and the value of the resistor is measured using a precision multi-meter. P15 is the jumper for VDD_EXT and P14 for VDD_INT. Once voltage and resistance are measured, the current is calculated by dividing the voltage by the resistance. For the highest accuracy, use a differential probe for measuring the voltage across the resistor.

Example ProgramsExample Analog Devices programs are provided with the ADSP-BF706 EZ-KIT Mini Board Support Package to demonstrate various capabilities of the product. Refer to a readme file provided with each example for more information.

Various third party demos and software examples are also available at: www.analog.com/BF706EZKitMini.
