■ HANDLING DEVICES
• Preventing Latch-up
Latch-up may occur in a CMOS IC if a voltage greater than VCC or less than VSS is applied to an input or output
pin or if an above-rating voltage is applied between VCC pin and VSS pin. A latch-up, if it occurs, significantly
increases the power supply current and may cause thermal destruction of an element. When you use a CMOS
IC, do not exceed the maximum rating.
• Treatment of Unused Pins
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, for example, using a pullup or pull-down resistor.
• Power Supply Pins
In products with multiple VCC or VSS pins, the pins of the same potential are internally connected in the device
to avoid abnormal operations such as latch-up. However, you must connect the pins to external power supply
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 output current rating.
Moreover, connect the current supply source with the VCC and VSS pins of this device at the low impedance.
It is also advisable to connect a ceramic bypass capacitor of approximately 0.1 μF between VCC and VSS near
this device.
• Crystal Oscillator Circuit
Noise near the X0, X1, X0A and X1A pins may cause the device to malfunction. Design the printed circuit board
so that X0, X1, X0A and X1A pins the crystal oscillator (or ceramic oscillator), and the bypass capacitor to ground
are located as close to the device as possible.
It is strongly recommended to design the PC board artwork with the X0, X1, X0A and X1A pins surrounded by
ground plane because stable operation can be expected with such a layout.
Please ask the crystal maker to evaluate the oscillational characteristics of the crystal and this device.
• Notes on Using External Clock
When external clock is selected, supply it to X0 pin generally, and simultaneously the opposite phase clock to
X0 must be supplied to X1 pin. However, in this case the stop mode (oscillation stop mode) must not be used.
(This is because the X1 pin stops at High level output in STOP mode.)
Using an external clock (normal)
X0
X1
Note : The STOP mode (oscillation stop mode) cannot be used.

• Serial Communication
There is a possibility to receive wrong data due to the noise or other causes on the serial communication.
Therefore, design a printed circuit board so as to avoid noise.
Retransmit the data if an error occurs because of applying the checksum to the last data in consideration of
receiving wrong data due to the noise.
• Notes when using no sub-clock
Use a single-clock model if not using the sub-clock.
Always connect a resonator of 100 kHz or less on dual clock models.
• Treatment of NC or OPEN pins
Pins marked as NC and OPEN must be left open - circuit.
• Mode pins (MD0 to MD2)
These pins should be connected directly to VCC or VSS. To prevent the device erroneously switching to test mode
due to noise, design the printed circuit board such that the distance between the mode pins and VCC or VSS is
as short as possible and the connection impedance is low.
• Operation at start-up
The INIT pin must be held at the “L”level when turning on the power.
• Source oscillation input at power on
When turning the power on, maintain clock input until the device is released from the oscillation stabilization
wait state.
• Caution on operations during PLL Clock Mode
On this microcontroller, if in case the crystal oscillator breaks off or an external reference clock input stops while
the PLL clock mode is selected, a self-oscillator circuit contained in the PLL may continue its operation at its
self-running frequency. However, Fujitsu will not guarantee results of operations if such failure occurs.
• External bus setting
This device is guaranteed for use with a 16 MHz external bus.
If the base clock is set to 32 MHz with DIVR1 (external bus base clock division setting register) set to its initial
value, the external bus also operates at 32 MHz. When changing the base clock, set the external bus so that it
will not exceed 16 MHz.
• Pull-up control
The AC characteristics cannot be guaranteed if pull-up resistors are used for the pins used as external bus pins.

*1 : Pins become inputs and can be used to wakeup from STOP mode when the corresponding external interrupt
is enabled in ENIR and the pin is selected as an external interrupt input pin in EISSR.
*2 : Pins will be available to input and can be used to restore from the STOP mode when the corresponding external
interrupt is enabled in ENIR and the pin is selected as an external interrupt input pin in EPFR.
Input enabled
Input disconnect
: This indicates that the input function is available in this state.
: Disconnects the external input at the input gate immediately adjacent to the pin .
An "L" level is passed to internal circuits.
Output Hi-Z
: Turns the pin to high-impedance by preventing the pin drive transistor from driving.
Output maintained
: Indicates that pins maintain the output level they had prior to changing to this mode.
In other words, the pin outputs the value in accordance with the peripheral operation if
the internal peripheral that uses the output is operating, and the pin maintains its output
level if the pin is set as a port.
Maintain previous state : Indicates that output pins maintain the output level they had prior to this mode, or input
pins continue to operate.

• Pin states in external bus mode
• The external bus interface pins will be in an output mode while the device is in the settings initialization (INIT)
state. The pins is in the Hi-Z state while the INIT pin is at the “L” level. The value listed in the table is output
when the INIT pin goes to the “H” level.
• The external bus interface output functions for ports 2, 3, 9, E, and F can be disabled by setting EPFR. The
symbols in the table indicate :
B : External bus interface function mode (EPFR = 0)
P : General-purpose port or peripheral function mode (EPFR = 1)

*1 : Pins become inputs and can be used to wakeup from STOP mode when the corresponding external interrupt
is enabled in ENIR and the pin is selected as an external interrupt input pin in EISSR.
*2 : Outputs go to Hi-Z at power on or while the INIT pin is at the “L” level starting from the falling edge on the
INIT pin.
Input enabled
Input disconnect
: This indicates that the input function is available in this state.
: Disconnects the external input at the input gate immediately adjacent to the pin .
An "L" level is passed to internal circuits.
Output Hi-Z
: Turns the pin to high-impedance by preventing the pin drive transistor from driving.
Output maintained
: Indicates that pins maintain the output level they had prior to changing to this mode.
In other words, the pin outputs the value in accordance with the peripheral operation if
the internal peripheral that uses the output is operating, and the pin maintains its output
level if the pin is set as a port.
Maintain previous state : Indicates that output pins maintain the output level they had prior to this mode, or input
pins continue to operate.

*2 : The maximum output current specifies the peak current for an individual pin.
*3 : The average output current specifies the average current that flows through an individual pin over a period of
100 ms. The average value is the operating current × operation ratio.
*4 : The total average output current specifies the average current that flows through all of the pins over a period
of 100 ms. The average value is the operating current × operation ratio.
*5 : The +B input rating specifies the current for an individual pin.

MB91270 Series
[ For +B input (12V to 16V) ]
1. Do not connect the +B potential directly to a microcontroller pin.
2. Always place a current-limiting resistor between the +B signal and microcontroller pins.
IIHH = 2mA per pin (Max) [during normal operation and during transients such as when turning the power on
or off]
3. Although the internal protection diode in the microcontroller causes the potential between the +B input-limiting resistor and microcontroller pin to be equal to the VCC + on voltage of the protection diode, do not use a
circuit structure that obstructs this operation or that causes this potential to be exceeded.

*1 : For FCP = 32 MHz, tSMP = (Rext + Rin) × Cin × 7 = ST × CLKP period = 2 ch × 31.25 ns = 1.375 μs
*2 : For FCP = 32 MHz, tCMP = CKIN × 11 = CT × CLKP period × 11 = 4 h × 31.25 ns × 11 = 1.375 μs
*3 : For FCP = 32 MHz, this is equivalent to the conversion time per channel when tSMP and tCMP are selected.
*4 : Specifies the power supply current when the A/D converter is not operating and the CPU is in stop mode
(Vcc = AVcc = AVRH = 5.0 V)
Notes : •The error becomes proportionately larger as the AVRH voltages go lower.
• Use the device with external circuits of the following output impedance rS for analog inputs :
External circuit output impedance rS = 5 kΩ (Max)
• If the output impedance of the external circuit is too high, the analog voltage sampling time may be
insufficient.
• If inserting a capacitor between the external circuit and an input pin to prevent direct current flow, select
a capacitance several thousand times larger than CSH to minimize the capacitive voltage divider effect
due to the CSH sampling capacitor in the chip.

• Definition of terminology
Resolution
Represents the change in analog signal enabled to be detected by the A/D converter.
For 10-bit conversion, the analog voltage can be resolved into 210 = 1024 increments.
Total error
This error indicates the difference between actual and theoretical values, and is the total value of errors that
results from offset error, gain error, nonlinear error, and noise.
Linearity error
Represents the difference between the actual conversion characteristic and the line between the zero transition
point (“00 0000 0000” ←→ “00 0000 0001”) and full scale transition point (“11 1111 1110”←→ “11 1111 1111”).
Differential linear error
Deviation of input voltage, which is required for changing output code by 1 LSB, from a desired value.
