Introduction
DIOPSIS® 940 HF Evaluation Board (part no. AT572D940-EB), DEB in short, is an effective platform for
evaluating chip performance and developing code for applications based on the DIOPSIS 940 HF.
From now on DIOPSIS 940 HF will be referred to as D940HF.
This manual is a description of the hardware included in the D940HF Evaluation Board (DEB).
The DEB is a system composed of two boards: the D940HF CPU Module (DCM) and the D940HF Back
Module (DBM). The DCM is plugged into the DBM by using SMD board connectors.
The DEB board will be described both at top level (see Section 2) and at single block level (see Section
5).
The complete collection of the DEB schematics is described in Section 6.
The main part lists are reported in Section 7.
For a detailed description of the DEB devices refer to the producer’s data sheet.

Introduction
Most of the platform jumpers are already set in order to provide the minimal resources to bootstrap the
D940HF chip. A brief description of the default configuration will follow in the next chapters.
The AT572D940-EB requires a 5 Volt DC (5%) switching power supply (included in the package) with
the following characteristics:
!
Input: 100-240VAC 50/60Hz 0.5A (IEC 320 Plug)
!
Output: 5VDC 2.4A 12W max
These values have been obtained taking into account the maximum power consumption of the DEB. See

The total power consumption of the DEB is: 1704 mA.
The power is supplied to the board via a coaxial cable with positive center pin polarity. The platform can
be switched on by simply plugging the power supply cable into the DBM female power connector J1
which has a maximum current rating of about 5A.
The user has the possibility to plug a battery (3 Volt Lithium Battery BR1225) in order to maintain time
and calendar resources permanently.
Note:
1-2
7014A–DSP–03/09
The operating voltage of some 3 Volt Lithium Batteries can be sometimes, when used for
the first time, above the nominal voltage declared by the manufacturer, and this can cause
malfunctioning of the RTC device on the board. The problem can be solved by plugging the
battery in its board socket for about 24 hours before using the RTC device, in order to discharge the battery and reduce the operating voltage level to the nominal value.

Mechanical Description
The PCB has been constructed by using Multi-Layer technology with controlled impedance paths, buried, blind and through holes. The PCB is also composed of twelve layers (with power planes). The DEB
is equipped with SMT components on both sides (top and bottom) with a minimum of through-hole components. The DCM board is plugged into the DBM board through two 120-pin connectors (60x2) whose
references are X1 and X3.
There is only one way to plug the DCM into the DBM: the DIP-Switch (SW1) and the Atmel logo of the
DCM must be on the same side of the DBM audio jack connectors.
Four holes at each corner of both the DBM and the DCM are provided on the PCBs in order to fit the four
supports for desk placement. The holes of the two boards are aligned and mechanical supports can be
added to the boards in order to place the complete system on both sides according to the resources to
be accessed.
The layouts of the two boards and of the mechanical dimensions are shown in the next paragraphs.

D940HF
The D940HF is a Dual Core System integrating an ARM926EJ-S™ ARM® Thumb® Processor Core and a
VLIW mAgic DSP™ optimized for audio, communication and beam-forming applications. The VLIW
mAgic DSP performs 1 GFlops - 1.6 GOps at 100 MHz. With its 1.7 MBits of On-chip SRAM, 32-bit integer and IEEE® 40-bit extended precision floating point numeric format, single cycle FFT butterfly, code
compression, SW pipelining, DMA engine and AHB master and slave ports, the DSP provides a very
powerful support to ARM and its rich set of peripherals. From now on, we refer to ARMSYSTEM as the
complete set of ARM core memories and its peripherals.
The D940HF can operate in two different modes: standard operational mode and test mode. Test mode
is only enabled for test purposes and it must not be enabled on the DCM board. The standard operational mode is selected by default with the S23 (JTAGSEL) and S25 (TST) jumper pins 1-3 closed.
5.2.2
Power Supply Logic
The DCM works with 3.3 Volt and 1.2 Volt power supplies. The 3.3 Volt power is supplied to the DCM by
the DBM through the Module Connectors. The DCM receives two separate 3.3 Volt power supplies for

Functional Blocks
the Ethernet PHY, that is already filtered on the DBM, and all the other devices. The other voltages, 2.5
Volt as the reference voltage level for the power measurement block and 1.2 Volt for the D940HF core,
are generated on board. The 1.2 Volt voltage is generated by the Power Supply Block that can host different types of voltage regulators (with or without Bias, with soft start reset capability or not, etc.). The
component reference is U1. The board now hosts the NCP565D2TG voltage regulator from ON-Semi.
This device works properly by setting the following configuration:

This configuration generates 1.2 Volt voltage level.
5.2.3
Power Measurement
The D940HF core power consumption can be measured and monitored by the Power Measurement
Block. This block, powered by an on board filtered 3.3 Volt power supply, is composed of a 0.25 Ohm
(1% precision) resistor (R25), a precision current sense amplifier with voltage output (U2), a pseudo differential 12-bit A/D converter (reference U3) controlled by the D940HF with the 2.5 Volt reference
voltage provided by an external precision LDO Voltage Reference (U5). The results of the measurements are received by the SPI1 Port (Chip Select 3).
The 2.5 Volt voltage level comes from a precision, micropower LDO Voltage Reference Generator (U5)
and it is needed by the Power Measurement Block.
Some reference values that can help the user translate the numbers coming from the A/D converter to
voltage and current values are reported in the table below:

Reset Logic
The D940HF incorporates a power on reset cell that generates the reset signal for all the internal and
external devices through the NRST pin J17.
Another internal source for the reset is the Watch Dog that is enabled at power up. The internal boot
ROM code disables it.

Functional Blocks
The DCM can also receive an active low pulse on the same NRST line from the DBM reset logic block
through the module connectors generated by a push-button device or by the NSRST pin of the ARM
Hardware JTAG if enabled on the DBM board.
The power on the reset cell of the D940HF is enabled by the external 3-pin jumper S33 (1-3 closed).
The DCM devices that receive the reset signal are the Parallel Flash memories (U11 and U12) and the
Ethernet PHY (U13).
5.2.5
Clock Logic
The 32.768 KHz quartz (Y2) provides the source for the D940HF embedded oscillator for the internal
slow clock that is enabled by the 2-pin jumpers S28 and S29 when open.
The 12 MHz quartz (Y1) provides the source for the D940HF embedded oscillator for the main clock
when the 2-pin jumper S26 is open.
The 3-pin jumper S30 (1-3 closed) disables the internal by-pass clock circuitry.

The J1 clock connector can be used as an alternative source clock either to provide the clock to the slow
clock input pin V2 (Y2 quartz must be not mounted and the 2-pin jumpers S28 and S27 closed, S24 and
S26 open) or to provide the clock to the main clock input pin U5 (Y1 quartz must be not mounted and the
2-pin jumpers S24 and S26 closed, S27 and S28 open).
The test points TP1 and TP2 can be used to monitor mAgic internal clock and ARM core internal clock
respectively.
The 3-pin S25 jumper (1-3 closed) enables the normal functional mode of the internal clock circuitry.
The Ethernet PHY device (U13) can receive the working clock either by the 50 MHz oscillator (Y6) that is
enabled by the DIP-Switch SW1-4 pin when OFF (default) or by the T15 pin of the D940HF (SW1-4 in
ON position).

Clock sources coming from the embedded peripherals of the D940HF through the PIO lines and going to
the external peripheral devices are serially terminated with 33 Ohm resistors.
The terminated PIO lines are: PA2, PA11, PB3, PB5, PB9, PB11, PB15, PB17, PB21, PB23, PC2, PC8,
PC13, PC18, PC21 and PC22.

Functional Blocks
5.2.6
SDRAM
The SDRAM Block is composed of two SDRAM chips with 16-bit bus size for a total of 32-bit bus size.
The U8 device is connected to the lower 16 bits of the external data bus while U9 is connected to the
higher 16-bit of the same bus.
The external data bus is shared among all the external memories (SDRAM, Parallel Flash and NAND
Flash) and the module connectors.
The DCM can host SDRAM memory chips up to 512 MBit density (size 32Mx16) for a total of 128 MByte
(two chips of 64 MByte each). The memory clock and the control signals come directly from the D940HF.
The SDRAM block can be disabled by hardware by opening the S35 jumper. The Chip Select signal is
controlled by the CS1 address space signal.
5.2.7
NAND Flash
The NAND Flash block is composed of only one chip that shares the least significant 8 bits of the external data bus. The DCM can host memory chips up to 4 GBit density (512Mx8). Write access operations
can be protected only by hardware. The DIP Switch SW1-2 pin enables the write operations when OFF
(default), as shown in the table below:.
Table 5-5. NAND Flash Write Protect
SW1-2 Status
Status
ON
Write Protect Enabled
OFF
Write Protect Disabled
The RDYBSY signal (pin 7 of the NAND Flash) sends the Ready/NotBusy information about the state of
the NAND Flash to the D940HF when the 3-pin jumper S10 is 1-3 closed. The Chip Enable pin of the
chip is controlled by the PA15 signal (D940HF pin V16).
5.2.8
Parallel Flash
The Parallel Flash Block is composed of two chips with a 16-bit bus size for a total 32-bit bus size. The
U11 device is connected to the lower 16 bits of the external data bus while the U12 is connected to the
higher 16 bits of the same bus.
The DCM can host Parallel Flash chips up to 64 MBit density (size 4Mx16) for total 16 MByte (two 8
MByte each chips).
Write Protection of the code can be performed in two ways: by hardware with the DIP Switch SW1-3 pin
in ON position (the chips are write protected) or by software with the SW1-3 pin OFF (chips are writable,
default position) and the 3-pin jumper S22 with 2-3 closed (the NWR0 write signal is masked by the PC5
signal, the pin G12 of the D940HF) as shown in the table below:

5.2.9
Ethernet PHY
The DCM hosts the Ethernet PHY DM9161 (U13) from Davicom that provides a Media Independent
Interface (MII) as defined in the IEEE 802.3u specifications. In particular the U13 component has been
configured in order to implement the Reduced Media Independent Interface (RMII) supported by the
D940HF Ethernet interface.
When in RMII mode the PHY receives the clock from the external source (either from Y6 oscillator,
default, or from D940HF) through pin 42 of U13.
An output interrupt line from the PHY (pin 32 of U13) is connected to PB25 (pin H15 of U6) internally
redirected to the Interrupt Controller (AIC) line EXTIRQ0.
The LINKSTS signal (pin 14 of U13) reflects the status of the network connection. The information can
be read by D940HF on the PB26 (pin B12 of U6) when the 3-pin jumper S15 is with pin 1-3 closed (see
Section 5.2.10 ”PIO Selectors” on page 5-5).
The status of the network connection can also be checked by the user by watching the three LEDs
located on the DBM and driven by the output signals of U13 LINK_ACT, SPEED and FDX_COL going
through the module connectors.
5.2.10
PIO Selectors
D940HF provides three groups of 32-bit PIO (Parallel Input/Output) lines: PA[31:0], PB[31:0] and
PC[31:0]. Each line can be dedicated to general purpose I/O or to the multiplexed signals from the
embedded peripherals according to the PIO internal register configuration.
The PIO Selector Block allows the user to connect the same PIO line to more than one external device at
a time depending on the implemented functionalities. In particular, the embedded peripheral and external device signals supported by the jumper block are: Compact Flash, Secure Digital, USART1,
USART2, CAN0, NAND Flash, Ethernet PHY.
The jumpers set an alternative between:
!
CAN0 and Ethernet Link Status
!
Secure Digital, Compact Flash, NAND Flash on one hand and USART2 on the other hand
!
Compact Flash and USART1
The possible choices are described in the following table (take note that only two pins can be closed at
the same time, for instance if pins 1-3 are closed, pins 2-3 will be open and viceversa):

ICE Interface Switch
The ICE Interface Switch Block allows the user to connect the hardware JTAG devices to the mAgic and
ARM JTAG ports both with two separate HW JTAGs or using only one HW JTAG with the two ICE ports chained.
There are three possible configurations:
!
Independent JTAG ports (mAgic and ARM ports not chained, default configuration)
!
mAgic to ARM chain (HW JTAG plugged into mAgic JTAG connector on the DBM)
!

Module Connectors
The DCM is plugged into the DBM by using the module connectors.
The connectors are used to provide the power supply to the DCM and to exchange signals between
D940HF and the peripheral support devices mounted on the DBM.
The DCM module male connectors are X1, X2 and X3, but only the corresponding X1 and X3 female
connectors are mounted on the DBM.
The X2 connector is an extension to be used with other motherboards:

Two on-board voltage regulators, located in the bottom part of the DBM board, provide the needed internal supplies starting from the 5V external PSU: 3.3 Volt (U1) and 4.5/3.3 Volt (U3). 5 Volt power can be
used directly by the USB Host connector through the S23 jumper (when closed) and by the optoisolator
component U17 via the 3-pin jumper S24 (U17 power is 5 Volt when pins 1-3 are closed otherwise the
power is 3.3 Volt when pins 2-3 are closed).

U3 VREG can be configured to supply either 4.5 Volt or 3.3 Volt power supply to the audio analog
operational amplifiers
A yellow LED (DS3) is connected to the 3.3 Volt power supply to show when the power is on.
The 3.3/4.5 Volt voltage power supplies are generated by a power supply block that can host different
types of voltage regulators (with or without Bias, with soft start reset capability or not, etc.). The board
now hosts two TPS75801 voltage regulators from Texas Instruments. U1 generates 3.3 Volt with the following settings:

U3 can generate 3.3 Volt by using U1 same settings and also with the FB1 ferrite mounted and FB2 not
mounted. The 3-pin jumpers S8, S10 and S11 must be with pins 1-3 closed (3.3 Volt power generation of
CODEC U5 disabled).
In order to generate 4.5 Volt the following settings are required for U3:

In this case the 3.3 volt power for the digital VDD of both CODECs is internally generated by the U5 component with the external help of the U4 component (PNP high current transistor).
Another ferrite (L3) is used to filter the power for the audio operational amplifiers.

Reset Logic
The DBM can receive an active low pulse on the open-drain NRESET line from the DCM D940HF
through the module connectors. On the other hand the SW1 push-button device on the DBM can force
an active low level on the same line.
A 2-pin remote reset connector (J4) is available to send/receive the reset signal to/from a remote system
as well.
An active low pulse can also be forced by the NSRST pin of the ARM Hardware JTAG if enabled by closing the 2-pin S15 jumper (default configuration).
The NRESET signal acts on the following DBM devices: U5 and U6 CODECs, J4 connector, J22 and
J26 header connectors (USART1 and USART2).
5.3.3
Clock Circuitry for CODECs
The U5 and U6 CODECs can receive the source clock signal both from the D940HF PB8 PIO line
through the X3 connector or from the on board Y1 device (12.288 MHz oscillator). The selection can be
done by setting the 3-pin S6 and 2-pin S7 jumpers as follows:

Audio Interface
The DBM Audio Interface Block provides eight audio channels (four stereo inputs and four stereo outputs) connected to eight audio jack connectors. Each channel works with a 24-bit word, I2S format, with
sampling rate up to 192 KHz. D940HF can connect to analog I/O signals through two AD1939 CODECs
located in the bottom part of the DBM board.
The AD1939 is a single-chip CODEC that provides four analog-to-digital converters with differential input
and eight digital-to-analog converters with differential output. An SPI port is included in order to configure
the CODECs.
The two CODECs are connected to the SSC0 Port in a daisy-chain mode in which the U6 is the first
component and U5 is the second component of the chain.
The SPI0 Port is used to control and configure the two CODECs (SPI NPCS01 control signal is connected to U5 and SPI0 NPCS02 control signal is connected to U6), but the control must be enabled by
hardware by closing the 2-pin jumpers S5 and S9 (default configuration). These jumpers can be disabled
when the user needs to use the SPI0 Port with the J24 header connector.

The U5 AD1939 outputs to audio jack connectors are low-pass filtered with an anti-image filter and converted from a differential voltage to a single-ended voltage by AD8608 quad op-amps. The quad opamps in U7 act on signals coming from the first two outputs (OUT1 and OUT2), while the ones in U8 on
the last two (3 and 4). The U5 CODEC outputs OUT1, OUT2, OUT3 and OUT4 (each one is a stereo
line) are connected to the corresponding audio jacks J5, J6, J7 and J8.

Connection to Ground
NTRST (pin 3 of both connectors) can be left unconnected if the HW JTAG device does not use this signal. S12 is the 2-pin jumper for the J13 connector used in order to leave the ICE_ANTRST signal
unconnected (S12 open, default configuration) on the DBM, because D940HF internal logic provides
directly the reset to the TAP controller.
The S13 2-pin jumper connected to pin 3 of J14 with ICE_MNTRST signal is left open by default.
The open collector ICE_ANSRST signal from pin 15 of J13 is connected by default to the NRESET line
of the DBM board through the 2-pin jumper S15 (closed), while the open collector MNSRST signal from
pin 15 of J14 is not connected to the NRESET line by default (S26 open).
It is also possible to enable (disabled by the default configuration) the ARM TCK<->RTCK local loop by
setting S14 and S16 jumpers as described in the table below (the corresponding settings must be used

Real Time Clock
The Real Time Clock (RTC) Block provides a serial alarm real-time clock (RTC) (DS1306, reference

The RTC provides a full binary coded decimal (BCD) clock calendar that is accessed by the SPI0 Port
using NPCS03 signal.
The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end
of the month date is automatically adjusted for months with fewer than 31 days, including corrections for
leap year. The clock operates either in the 24-hour or in the 12-hour format with AM/PM indicator.

DIOPSIS 940HF Evaluation Board User Guide
Functional Blocks
The DS1306 offers dual-power supplies as well as a battery-input pin. The dual-power supplies support
a programmable trickle charge circuit that allows a rechargeable battery to be used for a backup supply.
Two programmable time-of-day alarms are provided by the DS1306. Each alarm can generate an interrupt on a programmable combination of seconds, minutes, hours, and day.
A 1Hz clock output is also available through the 2-pin jumper S22 (when closed, default condition) both
for the D940HF and the Timer header connector J23.
The RTC provides an open-drain interrupt line (active low) usually asserted by the internal programmable alarm block. The interrupt line is connected to the IRQ1 signal that is shared with both the on board
interrupt push button SW2 and the SPI1 header connector.
The access control of SPI0 Port must be enabled by closing the 2-pin jumper S21 (default configuration).
This jumper must be disabled (open) when the user needs to use the SPI0 Port (Chip Select 3) with the
J24 header connector.

DBGU, USART0 and MIDI-IN
The DBGU, USART0 and MIDI-IN Block provides an external interface to the Debug Unit (DBGU) and
USART0 Ports of D940HF using an RS-232 transceiver (U16) and two DB9 male connectors (J17 for the
DBGU and J19 for the USART0).
An opto-isolator circuit has been added in order to translate a MIDI signal level from an external remote
system (such as a MIDI sequencer) to the RS-232 Receive signal level of the USART1 Port.
The RS-232 transceiver is a MAX3387E device with three receivers and three transmitters. The block
supports the DBGU Port communication using only receive and transmit signals while the support for
CTS and RTS signals has been added to the USART0 Port in order to allow the user to enable the hardware handshaking feature for the automatic flow control.

Header Connectors
The Header Connector Block provides an easy way to interface the D940HF ports to an external system.
The connectors are 12-pin vertical headers organized in two rows (6x2) located in the bottom part of the
DBM. The connector references start from J22 to J30.
The connectors can be used without any contention by configuring the DBM jumpers as reported in the
previous paragraphs and by checking the DCM Section 5.2.10 ”PIO Selectors” on page 5-5.
Take note that pull-up resistors have been added to the TWI lines TWD0, TWCK0, TWD1 and TWCK1
(J25, J29 and J30 connectors).
The connector pinout and functionalities are shown in the tables below:

Module Connectors
The DBM hosts the DCM by using only the two module connectors X1 and X3. The connectors are used
to provide the power supply to the DCM and to exchange signals between D940HF and the peripheral
support devices mounted on the DBM. The DBM module female connectors are X1 and X3 and provide
mechanical support to the DCM. But in order to improve the mechanical stability of the board when
plugged in, other supports are available as well.
