■ DESCRIPTION
The MB90990-series, loaded 1 channel FULL-CAN interface and Flash ROM, is general-purpose FUJITSU
16-bit microcontroller designing for automotive and industrial applications. Its main feature is the on-board CAN
Interfaces, which conform to Ver 2.0 Part A and Part B, while supporting a very flexible message buffer scheme
and so offering more functions than a normal FULL-CAN approach. With the new 0.18 μm CMOS technology,
Fujitsu now offers on-chip Flash ROM program memory up to 128 Kbytes.
The power supply (1.8 V) is supplied to the MCU core from an internal regulator circuit. This creates a major
advantage in terms of EMI and power consumption.
The internal PLL clock frequency multiplier provides an internal 31.25 ns instruction execution time from an
external 4 MHz clock. Also, the main clock can be monitored using the clock supervisor function.
The unit features a 4-channel input capture unit 1 channel 16-bit free-run timer, 2-channel LIN-UART,1 channel
UART, and 16-channel 8/10-bit A/D converter as the peripheral resource.
Note : F2MC is the abbreviation of FUJITSU Flexible Microcontroller.

■ HANDLING DEVICES
• Preventing latch-up
CMOS IC chips may suffer latch-up under the following conditions :
• A voltage higher than VCC pin or lower than VSS pin is applied to an input or output pin.
• A voltage higher than the rated voltage is applied between VCC pin and VSS pin.
• 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.
Use meticulous care not to exceed the rating.
For the same reason, also be careful not to let the analog power-supply voltage (AVCC, AVR) exceed the digital
power-supply voltage.
• Treatment of unused pins
Leaving unused input pins open may result in permanent damage of the device due to misbehavior or latch-up.
Therefore, they must be pulled up or pulled down through resistors. In this case, those resistors should be more
than 2 kΩ.
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.
• Using external clock
The high-speed oscillator pins (X0, X1) can not be used for external clock inputs.
• Notes on during operation of 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.
• Power supply pins (VCC/VSS)
• If there are multiple VCC and VSS pins, from the point of view of device design, pins to be of the same potential
are connected the inside of the device to prevent malfunction such as latch-up.
To reduce unnecessary radiation, prevent malfunctioning of the strobe signal due to the rise of ground level,
and observe the standard for total output current, be sure to connect the VCC and VSS pins to the power supply
and ground externally.
• Connect VCC and VSS pins to the device from the current supply source at a low impedance.
DS07-13753-3E
15
MB90990 Series
• As a measure against power supply noise, connect a capacitor of about 0.1 μF as a bypass capacitor between
VCC pin and VSS pin in the vicinity of VCC and VSS pins of the device.

• Pull-up/down resistors
The MB90990 series does not support internal pull-up/down resistors (Port 2 : built-in pull-up resistors) . Use
external components where needed.
• Crystal oscillator circuit
Noises around X0 or X1 pins may be possible causes of malfunctions. Make sure to provide bypass capacitors
via shortest distance from X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines, and make sure,
that lines of oscillation circuit 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. Please ask the crystal maker to evaluate the oscillational characteristics of the
crystal and this device.
• 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 and AVR) and analog inputs (AN0 to AN15) after
turning-on the digital power supply (VCC) .
Turn-off the digital power after turning off the A/D converter power supply and analog inputs. In this case, make
sure that the voltage does not exceed AVRH or AVCC.
• Connection of unused pins of A/D converter if A/D converter is not used
Connect unused pins of A/D converter to AVCC = VCC, AVSS = AVR = VSS.
• 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) .
• Stabilization of power supply voltage
A sudden change in the power supply voltage may cause the device to malfunction even within the specified
VCC power supply voltage operating guarantee range. Therefore, the VCC power supply voltage should be
stabilized.
For reference, the power supply voltage should be controlled so that VCC ripple variations (peak-to-peak value)
at commercial frequencies (50 Hz/60 Hz) fall below 10% of the standard VCC power supply voltage and the
coefficient of transient fluctuation does not exceed 0.1 V/ms at instantaneous power switching.

• Initialization
In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers,
turn on the power again.
• Notes on using CAN function
To use CAN function, please set “1” to DIRECT bit of CAN direct mode register (CDMR) .
If DIRECT bit is set to “0” (initial value) , wait states will be performed when accessing CAN registers.
Note : Please refer to Hardware Manual of “MB90990 series for detail of CAN Direct Mode Register”.
• Flash security function
The security bit is located in the area of the Flash memory.
If protection code 01H is written in the security bit, the Flash memory is in the protected state by security.
Therefore, please do not write 01H in this address if you do not use the security function.
Please refer to following table for the address of the security bit.

• Correspondence with TA = +105 °C or more
If used exceeding TA = +105 °C, please consult with us due to the restricted reliability.
It is ensured to write/erase data to the Flash memory between TA = − 40 °C and +105 °C.

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 are the same, the table in ROM can be referred without using
the far specification in the pointer declaration.
For example, an attempt to access 00C000H practically accesses the value at FFC000H in ROM.
The ROM area in bank FF exceeds 32 Kbytes, and its entire image cannot be shown in bank 00.
The image between FF8000H and FFFFFFH is visible in bank 00, while the image between FF0000H and
FF7FFFH is visible only in bank FF.

Notes : • The peripheral resources sharing the ICR register have the same interrupt level.
• When the peripheral resources sharing the ICR register use extended intelligent I/O service, only one
can use extended intelligent I/O service at a time.
• When either of the 2 peripheral resources sharing the ICR register specifies extended intelligent I/O
service, the other one cannot use interrupts.

*1 : This parameter is based on VSS = AVSS = 0 V.
*2 : Set AVCC and VCC to the same voltage. Make sure that AVCC does not exceed VCC and that the voltage at the
analog inputs does not exceed AVCC when the power is switched on.
*3 : VI and VO should not exceed VCC + 0.3 V. VI should not exceed the specified ratings. However, if the maximun
current to/from an input is limited by some means with external components, the ICLAMP rating supersedes the
VI rating.

• Use within recommended operating conditions.
• Use at DC voltage (current) .
• The +B signal should always be applied a connecting limit resistance 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 inputted when the microcontroller power supply 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 power supply voltage may not be sufficient to operate the power-on reset.
• Care must be taken not to leave the +B input pin open.
• Recommended circuit sample :
• Input/output equivalent circuits

• About the external impedance of analog input and its sampling time
A/D converter with sample and hold circuit. If the external impedance is too high to keep sufficient sampling
time, the analog voltage changed to the internal sample and hold capacitor is insufficient, adversely affecting A/
D conversion precision. Therefore, to satisfy the A/D conversion precision standard, consider the relationship
between the external impedance and minimum sampling time and either adjust the resistor value and operating
frequency or decrease the external impedance so that the sampling time is longer than the minimum value. And,
if the sampling time cannot be sufficient, connect a capacitor of about 0.1 μF to the analog input pin.
