MB90F378/V378
■ DESCRIPTION
The MB90378 series is a line of general-purpose, 16-bit microcontrollers designed for those applications which
require high-speed real-time processing. The instruction set is designed to be optimized for controller applications
which inheriting the AT architecture of F2MC-16LX family and allow a wide range of control tasks to be processed
efficiently at high speed.
A built-in LPC interface, serial IRQ and PS/2 interface simplifies communication with host CPU and PS/2 devices
in computer system. Moreover, SMbus compliant I2C*2 and A/D converter implements the smart battery control.
With these features, the MB90378 series matches itself as keyboard controller with smart battery control.
While inheriting the AT architecture of the F2MC*1 family, the instruction set for the F2MC-16LX CPU core of the
MB90378 series incorporates additional instructions for high-level languages, supports extended addressing
modes, and contains enhanced multiplication and division instructions as well as a substantial collection of
improved bit manipulation instructions. In addition, the MB90378 series has an on-chip 32-bit accumulator which
enables processing of long-word data.

■ DIFFERENCES AMONG PRODUCTS
Memory size
In evaluation with an evaluation product, note the difference between the evaluation product and the product
actually used. The following items must be taken into consideration.
• The MB90V378 does not have an internal ROM, however, operations equivalent to chips with an internal ROM
can be evaluated by using a dedicated development tool, enabling selection of ROM size by settings of the
development tool.
• In the MB90V378, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to FF3FFFH are
mapped to bank FF only. (This setting can be changed by the development tool configuration.)
• In the MB90F378, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to FF3FFFH are
mapped to bank FF only.

■ HANDLING DEVICES
1. Be sure that the maximum rated voltage is not exceeded (latch-up prevention).
A latch-up may occur on a CMOS IC if a voltage higher than VCC or lower than VSS is applied to an input or output
pin other than medium-to-high voltage pins. A latch-up may also occur if a voltage higher than the rating is
applied between VCC pin and VSS pin. A latch-up causes a rapid increase in the power supply current, which can
result in thermal damage to an element. Take utmost care that the maximum rated voltage is not exceeded.
When turning the power on or off to analog circuits, be sure that the analog supply voltages (AVCC, AVR) and
analog input voltage do not exceed the digital supply voltage (VCC).
2. Stabilize the supply voltages
Even within the operation guarantee range of the VCC supply voltage, a malfunction can be caused if the supply
voltage undergoes a rapid change. For voltage stabilization guidelines, the VCC ripple fluctuations (P-P value)
at commercial frequencies (50 Hz to 60 Hz) should be suppressed to "10%" or less of the reference VCC value.
During a momentary change such as when switching a supply voltage, voltage fluctuations should also be
suppressed so that the "transient fluctuation rate" is 0.1 V/ms or less.
3. Power-on
To prevent a malfunction in the built-in voltage drop circuit, secure "50 µs (between 0.2 V and 1.8 V)" or more
for the voltage rise time during power-on.
4. Treatment of unused input pins
An unused input pin may cause a malfunction if it is left open. Every unused input pin should be pulled up or down.
5. Treatment of A/D converter, and D/A converter power pin
When the A/D converter, D/A converter and comparator is not used, connect the pins as follows: AVCC = VCC,
AVSS = AVR = VSS.
6.
Notes on external clock
When an external clock is used, the oscillation stabilization wait time is required at power-on reset or at cancellation of sub-clock mode or stop mode. As shown in diagram below, when an external clock is used, connect
only the X0 pin and leave the X1 pin open.

X1
MB90378 Series
7. Power supply pins
When a device has two or more VCC or VSS pins, the pins that should have equal potential are connected within
the device in order to prevent a latch-up or other malfunction. To reduce extraneous emission, to prevent a
malfunction of the strobe signal due to an increase in the group level, and to maintain the local output current
rating, connect all these power supply pins to an external power supply and ground them.
The current source should be connected to the VCC and VSS pins of the device with minimum impedance. It is
recommended that a bypass capacitor of about 0.1 µF be connected near the terminals between VCC and VSS.
8. Analog power-on sequence of A/D converter and D/A converter
The power to the A/D converter and D/A converter (AVCC, AVR) and analog inputs (AN0 to AN11) must be turned
on after the power to the digital circuits (VCC) is turned on. When turning off the power, turn off the power to the
digital circuits (VCC) after turning off the power to the A/D converter, D/A converter and analog inputs. When the
power is turned on or off, AVR should not exceed AVCC. Also, when a pin that is used for A/D analog input is also
used as an input port, the input voltage should not exceed AVCC. (The power to the analog circuits and the power
to the digital circuits can be simultaneously turned on or off.)

Notes : • If single-chip mode (without ROM mirroring function) is selected, see Chapter 32, "ROM Mirroring
Function Selection Module" of the MB90378 series H/W manual.
• ROM data in the FF bank can be seen as an image in the higher 00 bank to validate the small model C
compiler. Because addresses of the 16 low-order bits in the FF bank are the same, the table in ROM
can be referenced without the "far" specification. For example, when 00C000H is accessed, the contents
of ROM at FFC000H are actually accessed. The ROM area in the FF bank exceeds 48 Kbytes, and all
areas cannot be seen as images in the 00 bank. Because ROM data from FF4000H to FFFFFFH is seen
as an image at 004000H to 00FFFFH, the ROM data table should be stored in the area from FF4000H to
FFFFFFH.

*1 : • For peripheral functions that share the ICR register, the interrupt level will be the same.
• If the extended intelligent I/O service is to be used with a peripheral function that shares the ICR register
with another peripheral function, the service can be started by either of the function. And if EI2OS clear is
supported, both interrupt request flags for the two interrupt causes are cleared by EI2OS interrupt clear
signal. It is recommended to mask either of the interrupt request during the use of EI2OS.
• EI2OS service cannot be started multiple times simultaneously. Interrupt other than the operating interrupt
is masked during EI2OS operation. It is recommended to mask either of the interrupt requests during the
use of EI2OS.
*2 : This priority is applied when interrupts of the same level occur simultaneously.

*1 : This parameter is based on VSS = AVSS = 0.0 V.
*2 : Set AVCC and VCC at the same voltage. Take care so that AVR does not exceed VCC + 0.3 V when the power is
turned on.
*3 : VI and VO shall never exceed VCC + 0.3 V.
*4 : The maximum output current is a peak value for a corresponding pin.
*5 : • Use within recommended operating conditions.
• Use at DC voltage (current).
• The +B signal should always be applied 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 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 supply voltage may not be sufficient to poerate the power-on reset.
• 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, etc.) cannot accept
+B signal input.
• Sample recommended circuits :

*2 : Set AVCC and VCC at the same voltage.
*3 : Take care so that AVR does not exceed VCC + 0.3 V when power is turned on.
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.

* : VCC must be kept lower than 0.2 V before power-on.
Notes : • The above values are used for causing a power-on reset.
Some registers in the device are initialized only upon a power-on reset. To initialize these registers, turn
on the power supply using the above values.
• Make sure that power supply rises within the selected oscillation stabilization time. If the power supply
voltage needs to be varied in the course of operation, a smooth voltage rise is recommended.

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.

It is recommended to keep the
rising speed of the supply voltage
at 50 mV/ms or slower.

Resolution : Analog changes that are identifiable with the A/D converter.
Linearity error : The deviation of the straight line connecting the zero transition point (“00 0000 0000” ↔
“00 0000 0001”) with the full-scale transition point (“11 1111 1110” ↔ “11 1111 1111”) from
actual conversion characteristics.
Differential linearity error : The deviation of input voltage needed to change the output code by 1 LSB from the
theoretical value.
Total error : The total error is defined as a difference between the actual value and the theoretical value, which
includes zero-transition error/full-scale transition error and linearity error.

7. Notes on Using A/D Converter
• About the external impedance of the 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 charged to the internal sampling and hold capacitor is insufficient, adversely affecting
A/D conversion precision.
• Analog input circuit model

• 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.

• If the sampling time cannot be sufficient, connect a capacitor of about 0.1 µF to the analog input pin.
• About errors
As |AVR − AVSS| becomes smaller, values of relative errors grow larger.
