3. REva motherboard
This chapter describes the REva's evaluation features and their limitations. Features are grouped into
thematic areas.
3.1 Power supply
You can choose the voltage to be used on the whole REva board as well as on the daughter board.
From the REva v3.0 onwards some daughter boards automatically configure the regulator and define
the possible sources for VDD.
3.1.1
External power supply
The REva motherboard can be powered by an external power supply which is not provided.
The characteristics of the power supply are:
●9V DC output, (5V for TR9 kits)
●2.1 x 5 mm jack connector with ground signal on the outside.
3.1.2 Possible power supply configurations
There are 3 possible modes for the configuration of the power supply:
Power supply configuration mode Scheme
Regulated voltage supplied from RLink
●The voltage of VDD is automatically
configured on the daughter board
●To be used with voltages below 3.8V
because RegIN is around 4.7V.

3. REva motherboard REva v3 User Guide
Power supply configuration mode Scheme
Regulated voltage supplied from the Jack
●The voltage of VDD is automatically
configured on the daughter board
●To be used with an external isolated and
filtered power supply (typically 9V, but 6V is
recommended for VDD lower than 3.6V).
5V supplied from the U B link
●To be used ONLY with 5V daughter boards
● Other daughter boards are generally
protected: the U B 5V wire can be opened
by the daughter board.
●The exact voltage is NOT 5V, but around
4.8V because of a low drop diode on the
RLink.
3.1.3 Features
The power supply features provided are:
●A jack for the connection of auxiliary 9V power supply to power the REva board. The 9V power
supply should output between 6V and 9V DC and have a 2.1 x 5 mm jack with the ground
signal on the outside.
●A two-position jumper for configuring the regulator input. When the jumper is in the Jack
position, the regulator input is the external 9V power supply. When it is in the U B position, the
regulator input is the U B power supply of the embedded RLink.
●A two position jumper to select the VDD source. The “regulated” positions have a meaning that
depends on the connected daughter board (auto-configuration of the power supply area by the
daughter board – refer to the daughterboard specific chapter in this documentation).
●A green LED which is lit when the REva board is powered.
3.1.4 Limitations
The U B 5V is actually 4.8V because a low drop diode is connected between the U B connector and
the board, to protect the PC. For an accurate 5V power supply, use an external power supply.
To use an external 9V DC power supply, the “Regulator Input” jumper must remain in the “Jack”
position and the “VDD selection” jumper must remain in the Reg OUT position.
With a 1.8V voltage, the LEDs on the board are dim and some features are not available (serial
communication, I²C EEPROM and temperature measurement).

3.2 Daughter board connection
The REva motherboard must be used with either a daughter board or an
external target board. This area can connect to a daughter board featuring a
target microcontroller for evaluation. This area may also be used to connect the
REva to another board with the appropriate connectors soldered to the bottom.
3.2.1 Features
The features of this area are:
●A standard O-DIMM connector to receive the daughter board. The
procedure of insertion/extraction is described in chapter 3.2 Daughter
Boards.
●A 72-position header for observation and measuring of useful signals.
●Two 40-position headers to which the other 72 positions of the O-DIMM
are connected, as well as some VDD and GND positions. This is useful for
obtaining multiple power supply signals when connecting the REva to
another board.
3.2.2 Limitations
The O-DIMM connector is guaranteed for 20 insertion-extraction cycles (more
in practice...).
3.3 SP/ SD connection area
This area allows the connection of an external RLink (Rlink-PRO). When doing
this, make sure the U B of the embedded RLink is disconnected. You must
then plug the jumpers of the RLink config and power sections of the REva board
as if you were using the embedded RLink.
The 24-pin connector can also be used to make the embedded RLink able to
drive an external target board. For that you will have to use an adapter
depending on the target protocol. You can use adapters from stand-alone
RLinks, or make your own using the information here:
http://raisonance-forum.xsalto.com/viewtopic.php?id=2449
3.4 Reset area
This area resets the devices on the daughter board.
3.4.1 Features
The features of this area are:
●1 push-button with a negative polarity.
●1 RC debouncing filter with a time constant of 330 us (soldered on the
bottom side of the board).
3.4.2 Limitations
Microcontrollers using a positive reset signal require an inverter embedded on
the daughter board.

3. REva motherboard REva v3 User Guide
3.5 Digital outputs area
This area provides the user with simple visible debug tools.
3.5.1 Features
The features of this area are:
●8 red transistor-driven LEDs that light up when the command is low. Current is supplied by the
power supply (9V or U B) and not by the microcontroller's pads.
●8 jumpers enabling the independent use of each LED. The use of an LED is enabled when the
corresponding jumper is plugged in.
●An LCD monitor connected to the D0-D3 LEDs signals. The LCD monitor features 26 * 96
pixels. It is equipped with an T7549T controller (the datasheet is provided on the CD). ome
examples show how to access its memory.
Note: The memory/registers of the LCD controller can only be written.

REva v3 User Guide 3. REva motherboard
3.6 Digital inputs area
This area provides the user with immediately usable digital I/Os that can be used as interrupt sources
or general purpose I/Os.
3.6.1 Features
The features of this area are:
●1 two-position jumper to choose the polarity of the BT6 push button.
●2 push buttons and 4 switches. When the switches are on or the buttons pressed, the
corresponding signal is tied to the ground (except for BT6 which depends on the chosen
polarity). Otherwise, the signals are floating.
●6 jumpers enabling independent use of these features. Use of a switch or a button is enabled
when the corresponding jumper is set.
3.6.2 Limitations
There are no debouncing filters connected to these buttons and switches. The user may use the
wrapping zone to add some, with the appropriate values for R and C.
When using buttons or switches, the corresponding pads of the microcontroller should be configured
as inputs, or I/Os with a pull-up resistor (or pull-down for BT6 with positive polarity), because there is
no external pull-up (pull-down).

3. REva motherboard REva v3 User Guide
3.7 Analog area
This area groups features where the user validates the analog features of a target microcontroller.
3.7.1 Features
The features of this area are:
●A four-position analog connector, including:
●Two analog inputs that can be connected directly to the ADC input pins of the
microcontroller,
●An analog output resulting from the integration of a PWM output. The integration is done
with a simple RC filter with a characteristic time of 100 ms,
●A ground connection.
●A potentiometer, that can be connected directly to the ADC input pins of the microcontroller.
●A temperature sensor, that can be connected directly to the ADC input pins of the
microcontroller. The output voltage of this sensor is given by the formula V=0.01(T+1).
●A buzzer that can be connected to the PWM microcontroller output through the PWM/BUZ
jumper.
●5 jumpers enabling independent use of these features. The analog feature can only be used
when the corresponding jumper is set.
3.7.2 Limitations
The output voltage of the temperature sensor is a function of the temperature. This means that past a
given threshold, depending on the power supply voltage, the measure cannot be accurate. This
threshold is approximately 30°C for a 3.3V power supply and 50°C for a 5V power supply.
The temperature sensor does not operate at 1.8V.

REva v3 User Guide 3. REva motherboard
3.8 Communication area
This area groups the connectors for several communication standards.
3.8.1 Features
²C
●A three-position connector for I²C communication.
●Pull-up resistors on the CL and DA lines (useful at the end of the I²C line).
●An I²C EEPROM ( T24C02-W) operating at voltages from 3V to 5.5V. Its address on the I²C
bus is 0xA0.
●A MEM accelerometer (LI 3LV02). Its address on the I²C bus is 0x3A.
Serial Communication
●An R 232 connector.
●A serial line driver ( T3232) operating at voltages from 3V to 5.5V.
SP
●A four-position connector for PI communication.
7 jumpers enabling the independent use of each of these features:
●CL and DA enable I²C communication.
●CK, MO I and MI O enable PI communication.
●RX and TX enable serial communication.
3.8.2 Limitations
The T3232 and the I²C EEPROM are designed to work at voltages between 3 and 5.5V. The
corresponding features cannot be used with 1.8V target microcontrollers. The I²C bus is not
guaranteed at this voltage.
Moreover, the maximum supply voltage for both the MEM accelerometer and the LCD monitor is
3.6V. Therefore, an independent voltage regulator (output: 3.3V) is specifically used for these devices.

3.9 Secondary serial / CAN area
This area allows the use of other serial communication protocols (CAN for example). It contains a DB9
connector with no driver and no other hardware.
To use this area, the daughter board must be equipped with the corresponding bus driver. This is the
only device dependent feature of the whole REva board.
3.10 Wrapping zone
This area allows the implementation of other useful, basic features that are not available on the REva
motherboard. It is made up of:
●96 general purpose positions
●8 VDD (target microcontroller power supply) positions
●8 GND (ground) positions
This wrapping area is obviously not designed to host large devices. To do so, connections to a
secondary wrapping board can be implemented in this area.
