PREFACE
Caution of the products described in this document
The following precautions will apply to the product described in this manual.
Indicate a potentially hazardous situation which, if not avoided appropriately, could
WARNING result in death or serious injury and/or a fault in the user’s system.
Electric shock,
Damage
Before performing any operation described in this manual, turn off all the power
supplies to the system. Performing such an operation with the power on may
cause an electric shock or device fault.
Electric shock,
Damage
Once the product has been turned on, do not touch any metal part of it. Doing so
may cause an electric shock or device fault.
CAUTION
Indicates the presence of a hazard that may cause a minor or moderate injury,
damages to this product or devices connected to it, or may cause to loose software
resources and other properties such as data, if the device is not used
appropriately.
Cuts, Damage
Before moving the product, be sure to turn off all the power supplies and unplug
the cables. Watch your step when carrying the product. Do not use the product in
an unstable location such as a place exposed to strong vibration or a sloping
surface. Doing so may cause the product to fall, resulting in an injury or fault.
Cuts
The product contains sharp edges that are left unavoidably exposed, such as
jumper plugs. Handle the product with due care not to get injured with such
pointed parts.
Damage
Do not place anything on the product or expose the product to physical shocks.
Do not carry the product after the power has been turned on. Doing so may cause
a malfunction due to overloading or shock.
Damage
Since the product contains many electronic components, keep it away from direct
sunlight, high temperature, and high humidity to prevent condensation. Do not use
or store the product where it is exposed to much dust or a strong magnetic or
electric field for an extended period of time. Inappropriate operating or storage
environments may cause a fault.
Damage
Use the product within the ranges given in the specifications.
Operation over the specified ranges may cause a fault.
Damage
Damage
To prevent electrostatic breakdown, do not let your finger or other object come
into contact with the metal parts of any of the connectors. Before handling the
product, touch a metal object (such as a door knob) to discharge and any static
electricity from your body.
Before turning the power on, in particular, be sure to finish making all the required
connections. Furthermore, be sure to configure and use the product by following
the instructions given in this document. Using the product incorrectly or
inappropriately may cause a fault.
Damage
Always turn the power off before connecting or disconnecting any cables from the
product. When unplugging a cable, unplug the cable by holding the connector part
without pulling on the cable itself. Pulling the cable itself or bending it may expose
or disconnect the cable core, resulting in a fault.
Damage
Because the structure of the MCU socket does not allow an evaluation MCU to be
mounted in the incorrect orientation, be very careful of the orientation of the
evaluation MCU when mounting it. Inserting the evaluation MCU in the wrong
orientation may damage the MCU, causing the MCU to become faulty.
Damage
Because the product has no casing, it is recommended that it be stored in the
original packaging. Transporting the product may cause a damage or fault.
Therefore, keep the packaging materials and use them in case of for the reshipment of the product.

3.5.7 Wake Up Operation
There is a wake up key in the LCD EV-Board, which uses external interrupt to wake up
system from sleep mode.
When system enters sleep mode, no operation can be made except the wake-up key.
The following operation describes the wake-up process.
When the timer is the same with standby setting time, system will enter sleep mode
Press wake up key, system enters normal status; timer counts continuously.

3.5.8 Reset Operation
There is reset key to be used when user wants to reset system. In normal condition the reset
pin is connected to VCC when it is pressed to connect to GND by reset key.
3.5.9 Test Pin
For every pin of MB95F310 there is a test pin connecting to it.
3.5.10 Battery Usage
The supply power is 3.3V for MCU EEPROM and MAX232. The LCD EV-Board uses power
chip AMS1117-3.3 to transfer input power from 5V to 3.3V, so the max battery supply is four
cells (1.5V each cell).

5 Development Platform Quick Start
5.1
Tools Setup Sequence
Start the debugging system in the following sequence:
Connect a BGMA to the PC with a USB cable, confirm the LED on the BGMA is Green;
Connect an EV-board to BGMA IDC10 socket;
Select the EV-board power supply and turn on the EV-board, confirm the LED on the
BGMA is Orange and the Power LED on the EV-board is on.
5.2
Open Project and Start Debug
Users can start a debug from a PC software SOFTUNE workbench in the following
sequence. Here take SIMULATE LCD EVBOARD project for example.
Start the SOFTUNE from “Startup Menu>Programs> SOFTUNE V3> FFMC-8L Family
SOFTUNE Workbench” in Windows;
Click “Open workspace” from “File” Menu in SOFTUNE;
Select “SIMULATE LCD EVBOARD.wsp” in “Open Space” window;
Click “Start debug” from “Debug” Menu.
If the entire procedure goes right, a debug will start normally.
5.3
Operation Precautions
All pins of MB95F310 Series MCU are connected to Testing Pin on the EV-board. If user
wants to test separate pin performance, please connect to the test pin.
Note: Before connecting with BGMA, do not power on system.
It’s recommended that only one power supply is used as a power module input at a time.
