■ HANDLING DEVICES
(1) Preventing latch-up
CMOS IC chips may suffer latch-up under the following conditions :
• A voltage higher than VCC or lower than VSS is applied to an input or output pin.
• A voltage higher than the rated voltage is applied between VCC and VSS.
• The AVcc power supply is applied before the VCC voltage.
Latch-up may increase the power supply current drastically, causing thermal damage to the device.
For the same reason, care must also be taken in not allowing the analog power-supply voltage (AVCC, AVRH) to
exceed the digital power-supply voltage.
(2) Handling unused pins
Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the
device. Therefor they must be pulled up or pulled down through resistors. In this case those resistors should be
more than 2 kΩ.
Unused bi-directional pins should be set to the output state and can be left open, or the input state with the
above described connection.
(3) Using external clock
To use external clock, drive X0 pin only and leave X1 pin unconnected.
Below is a diagram of how to use external clock.
MB90435 Series
X0
Open
X1
(4) Use of the sub-clock
Use one clock system parts when the sub-clock is not used. In that case, pull-down the pin X0A and leave the
pin X1A open. When using two clock system parts, a 32 kHz oscillator has to be connected to the X0A and X1A
pins.
(5) Power supply pins (VCC/VSS)
In products with multiple VCC or VSS pins, the pins of a same potential are internally connected in the device to
avoid abnormal operations including latch-up. However you must connect the pins to an external power and a
ground line to lower the electro-magnetic emission level to prevent abnormal operation of strobe signals caused
by the rise in the ground level, and to conform to the total current rating.
Make sure to connect VCC and VSS pins via the lowest impedance to power lines.
It is recommended to provide a bypass capacitor of around 0.1 µF between VCC and VSS pins near the device.

(6) Pull-up/down resistors
The MB90435 Series does not support internal pull-up/down resistors (except Port0 − Port3 : pull-up
resistors) . Use external components where needed.
(7) Crystal Oscillator Circuit
Noises around X0 or X1 pins may be possible causes of abnormal operations. Make sure to provide bypass
capacitors via the shortest distances from X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines,
and make sure, to the utmost effort, that lines of oscillation circuits do not cross the lines of other circuits.
It is highly recommended to provide a printed circuit board artwork surrounding X0 and X1 pins with a ground
area for stabilizing the operation.
(8) Turning-on Sequence of Power Supply to A/D Converter and Analog Inputs
Make sure to turn on the A/D converter power supply (AVCC, AVRH, AVRL) and analog inputs (AN0 to AN7) after
turning-on the digital power supply (VCC) .
Turn-off the digital power after turning off the A/D converter supply and analog inputs. In this case, make sure
that the voltage does not exceed AVRH or AVCC (turning on/off the analog and digital power supplies simultaneously is acceptable) .
(9) Connection of Unused Pins of A/D Converter
Connect unused pins of A/D converter to AVCC = VCC, AVSS = AVRH = VSS.
(10) N.C. Pin
The N.C. (internally connected) pin must be opened for use.
(11) Notes on Energization
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at
50 µs or more (0.2 V to 2.7 V) .
(12) Initialization
In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers,
please turn on the power again.
(13) Directions of “DIV A, Ri” and “DIVW A, RWi” instructions
In the Signed multiplication and division instructions (“DIV A, Ri” and “DIVW A, RWi”) , the value of the
corresponding bank register (DTB, ADB, USB, SSB) is set in “00H”.
If the values of the corresponding bank registers (DTB, ADB, USB, SSB) are set to other than “00H”, the remainder
by the execution result of the instruction is not stored in the register of the instruction operand.
(14) Using REALOS
The use of EI2OS is not possible with the REALOS real time operating system.
(15) Caution on Operations during PLL Clock Mode
If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even
when there is no external oscillator or external clock input is stopped. Performance of this operation, however,
cannot be guaranteed.

* : Under development
Note : The high-order portion of bank 00 gives the image of the FF bank ROM to make the small model of the C
compiler effective. Since the low-order 16 bits address are the same, the table in ROM can be referenced
without using the “far” specification in the pointer declaration.
For example, an attempt to access 00C000H accesses the value at FFC000H in ROM.The ROM area in bank
FF exceeds 48 Kbytes, and its entire image cannot be shown in bank 00.The image between FF4000H and
FFFFFFH is visible in bank 00, while the image between FF0000H and FF3FFFH is visible only in bank FF.

*1 : The interrupt request flag is cleared by the EI2OS interrupt clear signal.
*2 : The interrupt request flag is cleared by the EI2OS interrupt clear signal. A stop request is available.
Notes : • N/A : The interrupt request flag is not cleared by the EI2OS interrupt clear signal.
• For a peripheral module with two interrupt causes for a single interrupt number, both interrupt request flags
are cleared by the EI2OS interrupt clear signal.
• At the end of EI2OS, the EI2OS clear signal will be asserted for all the interrupt flags assigned to the same
interrupt number. If one interrupt flag starts the EI2OS and in the meantime another interrupt flag is set by
a hardware event, the later event is lost because the flag is cleared by the EI2OS clear signal caused by the
first event. So it is recommended not to use the EI2OS for this interrupt number.
• If EI2OS is enabled, EI2OS is initiated when one of the two interrupt signals in the same interrupt control
register (ICR) is asserted. This means that different interrupt sources share the same EI2OS Descriptor
which should be unique for each interrupt source. For this reason, when one interrupt source uses the
EI2OS, the other interrupt should be disabled.

*1 : AVCC, AVRH, AVRL should not exceed VCC. Also, AVRH, AVRL should not exceed AVCC, and AVRL does not
exceed AVRH.
*2 : VI and VO should not exceed VCC + 0.3 V. VI should not exceed the specified ratings. However if the maximum
current to/from an input is limited by some means with external components, the ICLAMP rating supercedes the
VI rating.
*3 : The maximum output current is a peak value for a corresponding pin.
*4 : Average output current is an average current value observed for a 100 ms period for a corresponding pin.
*5 : Total average current is an average current value observed for a 100 ms period for all corresponding pins.
*6 : • Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67,
P70 to P77, P80 to P87, P90 to P97, PA0
• Use within recommended operating conditions.
• Use at DC voltage (current) .
• The +B signal should always be applied with a limiting resistance placed between the +B signal and the
microcontroller.
• The value of the limiting resistance should be set so that when the +B signal is applied the input current to
the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.
• Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input
potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect
other devices.
• Note that if a +B signal is input when the microcontroller current is off (not fixed at 0 V) , the power supply is
provided from the pins, so that incomplete operation may result.
• Note that if the +B input is applied during power-on, the power supply is provided from the pins and the
resulting supply voltage may not be sufficient to operate the power-on result.

• Care must be taken not to leave the +B input pin open.
• Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input
pins, etc.) cannot accept +B signal input.

“tcp” represents one cycle time of the machine clock.
Oscillation time of oscillator is time that amplitude reached the 90%. In the crystal oscillator, the oscillation time is
between several ms to tens of ms. In FAR/ceramic oscillator, the oscillation time is between handreds of µs to
several ms. In the external clock, the oscillation time is 0 ns.
Any reset can not fully initialize the Flash Memory if it is performing the automatic algorithm.

Sudden changes in the power supply voltage may cause a power-on reset.
To change the power supply voltage while the device is in operation, it is recommended to
raise the voltage smoothly to suppress fluctuations as shown below.
In this case, change the supply voltage with the PLL clock not used. If the voltage drop is
1 V or fewer per second, however, you can use the PLL clock.

• Notes on Using A/D Converter
Select the output impedance value for the external circuit of analog input according to the following conditions, :
• Output impedance values of the external circuit of 15 kΩ or lower are recommended.
• When capacitors are connected to external pins, the capacitance of several thousand times the internal
capacitor value is recommended to minimized the effect of voltage distribution between the external capacitor
and internal capacitor.
Note : When the output impedance of the external circuit is too high, the sampling period for analog voltages may
not be sufficient (sampling period = 4.00 µs @machine clock of 16 MHz) .
