REva User Guide: Mother Board 1. Presentation
1. Presentation
The REva is a universal evaluation board that has been designed for quick
and easy evaluation of a wide range of microcontrollers. It is made up of a
generic REva mother board with embedded RLink in-circuit programmer and
debugger, and a daughter board featuring a target microcontroller.
IMPORTANT NOTE:
This manual describes different versions of the REva boards. The major part
of this User Guide refers is common to all the existing REva boards. For the
parts where the boards differ, a notice (in blue) will indicate it.
Version Short description
REva v1 First version of the REva board.
REva v2 Very similar to V1.0, but the voltage of the regulator is now fixed by the
daughter board itself (instead of a set of jumpers on the REva board).
REva RF 'ZigBee' The REva RF 'ZigBee' is designed for RF applications and features an
extension connector to plug a RF external module.
REva v3 The RLink is not breakable anymore. New peripherals are also added: LCD
monitor, MEMS accelerometer, ...
A DIFFERENT MANUAL DESCRIBES THE REva v3 (AND LATER).
The REva's key features include:
●Digital and analog I/O evaluation features including on-board LEDs,
buttons, switches, external analog connector, temperature sensor
and potentiometer,
●On-board I²C EEPROM and bus extension connector,
●On-board RS232 driver and DB9 connector,
●SPI, CAN and USB connections (depending on the target device),
●Embedded RLink for in-circuit debugging and in-circuit programming,
●VDD settings for 1.8V, 3.3V and 5V microcontrollers,
●USB powered, no external power required.
This chapter gives an overview of the REva package and the physical
characteristics of the mother board.

1. Presentation REva User Guide: Mother Board
At the time of manufacturing, the REva and the RLink are connected to allow in-circuit debugging and
in-circuit programming of the microcontroller on the REva daughter board without additional power
supply or cables.
The two tools can also be easily broken apart so that both the REva and the RLink can be used
independently, or together. This requires the use of the furnished cable and an additional power supply
(not furnished) for the REva.

Illustration 2: Overview of the REva mother board with RLink

REva User Guide: Mother Board 1. Presentation
Note: When separated from the REva, the RLink has the same in-circuit debugging and programming
characteristics as the stand-alone RLink version 2.0.
As a result there are two possible configurations for using the REva:
●“Attached Mode”: REva and RLink boards are attached, no connection cable is required and
power is supplied by the USB connection (see paragraph 2.1).
●“Broken apart mode”: The REva is connected to the RLink (or other tool that supports in-
circuit debugging and programming) via a connection cable. Power is supplied by a 9V
auxiliary power supply (see Illustration 3 and paragraph 2.2).

1.2 REva-RLink connection
The REva and the RLink are connected by eight points at the time of manufacturing. Through these
points, 16 signals are passed including those for:
●in-circuit debugging
●in-circuit programming
●USB power supply
●the grounds of the two boards
!!! Warning !!!
After the boards are broken apart, you must use the provided cable to connect the boards and
an external 9V power supply. Only break the boards apart if it is required for your application.
To break apart the two boards, place the separation along the edge of a desk. Then, press down on the
RLink with one hand while maintaining the mother board with the other hand.

2. Operating modes
The following chapter provides a detailed description of each of the REva's
major operating configurations/modes:
●Attached Mode: boards connected and powered from USB
●Broken Apart Mode: boards separated and powered by a 9V auxiliary
power supply
Raisonance - 12 -

REva User Guide: Mother Board 2. Operating modes
2.1 Attached Mode: USB Powered, on-board ISP/ISD
In this mode, 1.8V daughter boards are not supported.
The RLink must not be used to program external target microcontrollers when a daughter board
is inserted.
- 13 - Raisonance

2. Operating modes REva User Guide: Mother Board
2.2 Broken Apart Mode: Auxiliary power supply, cable ISP/ISD
There are no restrictions for this mode.
This is the only mode that allows the debugging and programming of 1.8V target microcontrollers.

3.1 Layout of the REva mother board
Illustration 6 shows the thematic areas for the REva's evaluation features.
The REva mother board exists in two versions. The version number (1.0 or 2.0) is printed on the
mother board next to the SO-DIMM connector.
The only difference between the two versions is in the jumpers in the power supply area. The following
sections describe the use of the power supply area for each version.

3.2 Power supply area (REva v1.x)
This area allows you to choose the voltage to be used on the whole REva board as well as on the
daughter board. Because of the dropout voltage of the regulator, the 5V voltage cannot be generated
from the USB 5V. Thus, to use 5V target microcontrollers without external power supply, the USB
power supply must not pass through the regulator but must be used directly.

3.2.3 Features
●1 jack for the connection of auxiliary 9V power supply to power the REva board in broken apart
mode. Should you require one, the 9V power supply should output 9V DC and have a 2.1x5mm
jack with the ground signal on the outside.
●1 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 “USB” position, the
regulator input is the USB power supply of the embedded RLink.
●1 three-position jumper to configure the regulator. This defines the voltage delivered by the
regulator. When no jumper is set, the voltage is 1.8V.
●1 two position jumper to select the VDD source. It can be either the 5V of the embedded USB or the
output of the regulator (which must then be properly configured).
●1 green LED which is lit when the REva board is powered.
3.2.4 Limitations
The USB 5V is actually 4.8V because a low drop out diode is connected between the USB connector
and the board, to protect the PC. For accurate 5V power supply, use an external power supply.
Once the RLink has been separated from the REva mother board, the USB power supply is no
longer connected to the power supply area. The use of an external 9V DC power supply is mandatory,
the “Regulator Input” jumper must remain in the “Jack” position and the “VDD selection” jumper must
remain in the “REG” position.
With 1.8V power supply, the LEDs on the board are dim and some features are not available (serial
communication, I²C EEPROM and temperature measurement).

3.3 Power supply area (REva v2.x)
This area allows to choose the voltage to be used on the whole REva board as well as on the daughter
board. On the REva v2.0 the daughter board configures automatically the regulator and defines the
possible sources for VDD. Direct USB 5V must not be used with 3.3V daughter boards. It could
damage them.
