2.2 Power Management Unit
2.2.1 Battery Power Supply
2.2.2 External Power Supply Connection
The Power Management unit allows three different power supply sources along with a
set of solder strap allowing configuration of “Very Low Voltage 1.8V application” or “Low
Voltage 3V application”. Figure 2-3 shows the power management unit implementation.
Jumpers J36, J37, J38, J39 must always be in place for proper operation and are implemented for current measurement purpose only (see Section 2.14).
Figure 2-3. Power Management Unit Implementation
The AT85DVK-07 Board allows direct plug-in of a single AAA battery element or a AA
battery as an option.
Table 2-1. Battery Power Supply Range
Power supply source Min. Max. Unit
Battery Power Supply 0.9 1.5 V
In order to operate without battery during firmware development process the AT85DVK07 Board provides an external power supply input through connector J20.
Notes: 1. Remove any plugged battery from the socket before applying the external voltage.
2. The external power supply input is not protected against polarization inversion.

2.2.4 Power Configuration The power configuration is done through a s et of solder straps. By default, the
AT85DVK-07 Board is delivered configured in “Low Voltage 3V application” meaning all
external components (LCD, NF, MMC…) are powered at 3V.
Note: “Very Low Voltage 1.8V application” uses the on-chip 1.8V DC-DC of the
AT85C51SND3Bx while “Low Voltage 3V application” uses the external on-board DCDC.

2.2.5 External DC-DC Replacement
2.3 Microcontroller Unit
In order to allow developers to validate other external DC-DC power supply solution, two
extension connectors J19 and J22 (see Table 2-6 and Table 2-7) are provided as option
to plug a daughter board featuring an external 3V low voltage DC-DC.
In such configuration the board must be configured in “Low Voltage” mode and SE38
along with SE56 must be open.

The Remote Control unit is split in two different units: the Serial Remote Control Unit
and the Parallel Remote Control Unit.
2.4.1 Serial Remote Unit The Serial Remote Control unit implements a 6-pin connector J23 sharing the UART
and high-speed SPI Interfaces. This connector allows easy connection with a host able
to control the audio player remotely.
Note: The AT85DVK-07 Board is supplied without any RS-232 driver/receiver.

The Audio Output unit consists in 2 stereo 3.5 mm jacks J7 & J8 allowing output selection between on-chip audio codec (with its optional on-board headphone amplifier) and
on-board audio DAC. Moreover 2 extension connectors J5 and J9 (see Table 2-15 and
Table 2-16) allow user to plug daughter boards replacing on-board headphone amplifier
or on-board audio DAC. In this case, solder straps SE1, SE2, SE19, SE18, SE51 for
external headphone amplifier and SE49, SE50 for external audio DAC must be left
opened to avoid short circuits.
Note: On-board DAC and on-chip DAC (audio codec) usage is exclusive. User’s selection can
be configured in the audio firmware driver (for further information, refer to the firmware
user’s manual).

2.10 FM Receiver Unit
The FM unit consists in 2 extension connectors J1 & J2 (see Table 2-17 and Table 2-18)
allowing user to plug a daughter board featuring a FM receiver.
Note: Using P4.3:0 I/O port to control the FM receiver chip implies that the on-board DAC can
not be used in this configuration.

2.11 Display Unit
2.12 Keypad Unit
The Display unit consists in a 128x64 monochrome pixels LCD. It is possible to plug a
daughter board equipped with an other LCD (color, higher resolution…) using J11 connector (see Section 2.4.2).
Note: On-board LCD must be disconnected before plugging any daughter boards.
The Keypad unit consists in a 3 x 4 key matrix including a 4-direction mini joystick and
power-on key along with 2 extension connectors. J10 & J30 allow user to plug a daughter board featuring particular keys like 2-direction mini joystick, rolling wheel…
Note: To ease software implementation with generic software keypad driver, user’s keypad
arrangement must fit with an available matrix configuration (for further information, refer
to the firmware user’s manual).

2.13 On-Chip Debug Unit
The On-Chip Debug (OCD) unit consists in a 10-pin or 6-pin connector J26 allowing
connection of the OCD dongle V1 or V2 through a flat cable. This dongle is part of the
development kit and allows debugging of the firmware using Keil’s Integrated Development Environment.

2.14 Power Consumption Measurement
In order to ease the power supply measurement, 4 jumpers are implemented as detailed
in Figure 2-19:
Figure 2-19. Power Management Unit Implementation
J37
– This jumper allows insertion of a ammeter on VBUS power supply.
– Mass storage power consumption can be monitored using this jumper.
J36
– This jumper allows insertion of a ammeter on AT85C51SND3Bx HVDD power
supply.
– The AT85C51SND3Bx HIDD power consumption can be monitored using this
jumper.
2.15 USB Storage Device Connection
J38
– This jumper allows insertion of a ammeter on AT85C51SND3Bx LVDD power
supply.
– The AT85C51SND3Bx LIDD power consumption can be monitored using this
jumper.
J39
– This jumper allows insertion of a ammeter on board VDD power supply (LVDD or
HVDD depending on power configuration).
– The NF, MMC, LCD… power consumption can be monitored using this jumper.
Note: In order to remove non significant consumption linked to the led power supply (HVDD),
remove SE31 solder strap.
A USB storage device can be connected to the AT85DVK-07 Board using the “Mini A to
Receptacle A USB cable” as shown in Figure 2-20.
In order to power the USB storage device, an external 5V controlled VBUS power supply must be connected to J24 (see Table 2-10) according to Figure 2-21.
The VBUS power supply is controlled by the active-low UVCON signal.

2.16 Nand Flash Board Extension
The Nand Flash bare PCB is delivered to make easy new Nand Flash testing.
The AT85C51SND3Bx Nand Flash drivers support up to 4 nand flash with 1x, 2x or 4x
configuration. The Nand Flash extension board can be configured for operation with single CE or double CE Nand Flash memories (double dies per package).
Figure 2-22 shows the board implementation while Table 2-23 and Table 2-24 summarize the board configuration depending on Nand Flash memory type.
Note: In order to fit with generic software driver, the Nand Flash memories soldered on one
board must be of same part number.

Development Board Errata List
• On-Board 3V DC-DC - Bad Startup
DC-DC is not properly maintained after power-up.
Workaround:
Do not use external DC-DC: power the board using USB cable.
• Microphone Input - DC Decoupling
The decoupling capacitor is missing between microphone and MICIN input.
Workaround:
Add 1uF capacitor between microphone and MICIN input (layout cut).
• External DAC - Conflict Using SPI/SIO Interface
External DAC being controlled by the SPI/SIO lines, SPI or SIO transfers are
disturbed by the SPI_DOUT line when SPI_CSB line is asserted.
Workaround:
Insulate SPI DAC control lines (layout cut).
• LCD - Display Stability @ 1.8V
The display shows flickering when operating @ 1.8V (LCD charge pump issue).
Workaround:
None.
4.2 Board V1.0.1
• LCD - Display Stability @ 1.8V
The display shows flickering when operating @ 1.8V (LCD charge pump issue).
Workaround:
None.
