2.2 Power
Management
Unit
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 imple-
mented for current measurement purpose only (see Section 2.14).
Figure 2-3. Power Management Unit Implementation
2.2.1 Battery Power
Supply
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
2.2.2 External Power
Supply Connection
In order to operate without battery during firmware development process the AT85DVK-
07 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 set 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 DC-
DC.
Table 2-5. Power Configuration
Notes: 1. Option to allow battery voltage monitoring by the AT85C51SND3Bx.
2. Option to allow power key-press detection by the AT85C51SND3Bx.
3. Remove this connection when using a daughter board DC-DC extension.

2.2.5 External DC-DC
Replacement
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.

Note: The AT85C51SND3Bx embeds a generic Nand Flash boot-loader.
2.4 Remote Control
Unit
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.
Figure 2-8. Serial Remote Control Unit Implementation
Table 2-8. Remote Control Connector (J23)
2.4.2 Parallel Remote Unit The Parallel Remote Control unit implements a 26-pin connector J11 sharing the PSI (8-
bit Parallel Slave Interface) UART and high-speed SPI Interfaces. This connector allows
easy connection with a host able to control the audio player remotely.
Note: The Parallel Slave Interface and Display Interface are sharing same signals. So on board
LCD must then be disconnected by removing its flat cable from J34 socket.

high-speed devices and full-speed reduced-host / OTG compliant applications. It con-
sists in a USB mini AB connector (including ID pin) and an OTG extension connector
J24 (see Table 2-10) which allows control of an external VBUS power supply able to
power USB device.
Details on how to connect a USB storage device to the AT85DVK-07 Board are pro-
vided in Section 2.15.

2.9 Audio Output
Unit
The Audio Output unit consists in 2 stereo 3.5 mm jacks J7 & J8 allowing output selec-
tion 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).

not be used in this configuration.

2.11 Display 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 con-
nector (see Section 2.4.2).
Note: On-board LCD must be disconnected before plugging any daughter boards.
2.12 Keypad Unit 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 daugh-
ter 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).
