■ DIFFERENCES AMONG PRODUCTS
Memory Size
In evaluation with an evaluation chip, note the difference between the evaluation chip and the chip actually used.
The following items must be taken into consideration.
• The MB90V520 does not have an internal ROM. However, operations equivalent to those performed by a chip
with an internal ROM can be evaluated by using a dedicated development tool, enabling selection of ROM
size by setting the development tool.
• In the MB90V520, images from FF4000H to FFFFFFH are mapped to bank 00, and FE0000H to FF3FFFH are
mapped to bank FE and FF only. (This setting can be changed by configuring the development tool.)
• In the MB90522, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to FF3FFFH to bank
FF only.
• In the MB90523/F523, images from FF4000H to FFFFFFH are mapped to bank 00, and FE0000H to FF3FFFH
to bank FE and bank FF.

■ HANDLING DEVICES
1. Ensuring that the Voltage does not exceed the Maximum Rating (to Avoid a Latch-up).
In CMOS ICs, a latch-up phenomenon is caused when a voltage exceeding VCC or below VSS is applied to
input or output pins or if a voltage exceeding the rating is applied across VCC and VSS.
When a latch-up is caused, the power supply current may be dramatically increased, resulting in thermal
breakdown of devices. To avoid the latch-up, make sure that the voltage does not exceed the maximum rating.
In turning on/turning off the analog power supply, make sure the analog power voltages (AVCC, AVRH, DVCC)
and analog input voltages do not exceed the digital voltage (VCC).
And also make sure the voltages applied to the LCD power supply pins (V3 to V0) do not exceed the power
supply voltage (VCC).
2. Handling Unused Pins
• Unused input pins left open may cause abnormal operation, or latch-up leading to permanent damage. Unused
input pins should be pulled-up or pull-down through at least 2 kΩ resistance.
• Unused input/output pins may be left open in output state, but if such pins are in input state they should be
handled in the same way as input pins.
3. Notes on Using External Clock
In using the external clock, drive X0 pin only and leave X1 pin unconnected.
• Using external clock
X0
MB90520 series
Open
X1
4. Unused Sub Clock Mode
If sub clock modes are not used, the oscillator should be connected to the X0A pin and X1A pin.
5. Power Supply Pins
In products with multiple Vcc or Vss pins, pins with the same potential are internally connected in the device to
avoid abnormal operations including latch-ups. However, the pins should be connected to external powers and
ground lines 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 lowest impedance to power lines.
It is recommended that a bypass capacitor of around 0.1 µF be placed between the Vcc and Vss pins near the
device.

6. Crystal Oscillator Circuit
Noise around the X0 and X1 pins may cause abnormal operation in this device. In designing printed circuit
boards, the X0 and X1 pins and crystal oscillator (or ceramic oscillator), as well as the bypass capacitor to the
ground, should be placed as close as possible, and the related wiring should have as few crossings with other
wiring as possible.
Circuit board artwork in which the area of the X0 and X1 pins is surrounded by grounding is recommended for
stabilizing the operation.
7. Turning-on Sequence of Power Supply to A/D Converter and Analog Inputs
Make sure to turn on the A/D converter power supply, D/A converter power supply (AVCC, AVRH, AVRL, DVCC,
DVSS) 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 AVRH and DVCC do not exceed AVCC (turning on/off the analog and digital supplies simultaneously is
acceptable).
8. Connection of Unused Pins of A/D Converter
Connect unused pins of A/D converter and those of D/A converter to AVCC = DVCC = VCC, AVSS = AVRH = AVRL
= VSS.
9. N.C. Pin
The N.C. (internally connected) pin must be opened for use.
10.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).
11.Use of SEG/COM Pins for the LCD Controller/Driver as Ports
In MB90520 series, pins SEG08 to SEG31, and COM0 to COM3 can also be used as general-purpose ports.
The electrical standard is such that pins SEG08 to SEG23, and COM0 to COM3 have the same ratings as the
CMOS output port, while pins SEG24 to SEG31 have the same ratings as the open-drain type.

12.Indeterminate outputs from ports 0 and 1
The outputs from ports 0 and 1 become indeterminate during oscillation setting time of step-down circuit (during
a power-on reset) after the power is turned on.
Pay attention to the port output timing shown as follow

* : 2:Oscillation setting time: 218/oscillation clock frequency (oscillation cllock frequency of 16 MHz: 16.38 ms)
13.Initialization
The device contains internal registers that can be initialized only by a power-on reset. To initialize the internal
registers, restart the power supply.
14. Interrupt Recovery from Standby
If an external interrupt is used for recovery from standby, use an “H” level input request. An “L” level request
causes abnormal operation.
15.Precautions for Use of “DIV A, Ri”, and “DIVW A, Ri” Instructions
The signed multiplication-division instructions “DIV A, Ri”, and “DIVW A, RWi” should be used when the
corresponding bank registers (DTB, ADB, USB, SSB) are set to value “00h”. If the corresponding bank registers
(DTB, ADB, USB, SSB) are set to a value other than “00h,” then the remainder obtained after the execution of
the instruction will not be placed in the instruction operand register.
16. Precautions for Use of REALOS
Extended intelligent I/O service(EI2OS) cannot be used, when REALOS is used.

Note: The ROM data of bank FF is reflected in the upper address of bank 00, realizing effective use of the C
compiler small model. The lower 16-bit of bank FF and the lower 16-bit of bank 00 are assigned to the
same address, enabling reference of the table on the ROM without stating “far.”
For example, if an attempt has been made to access 00C000H, the contents of the ROM at FFC000H are
actually accessed. Since the ROM area of the FF bank exceeds 48k bytes, the whole area cannot be
reflected in the image for the 00 bank. The ROM data at FF4000H to FFFFFFH looks, therefore, as if it
were the image for 00400H to 00FFFFH. Thus, it is recommended that the ROM data table be stored in
the area of FF4000H to FFFFFFH.

Descriptions for read/write
R/W: Readable and writable
R: Read only
W: Write only
Descriptions for initial value
0 : The initial value is “0.”
1 : The initial value is “1.”
X : The initial value is indeterminate.
*1: This area is the only external access area having an address of 0000FFH or lower. An access operation to this
area is handled as that to external I/O area.
*2: For details of the “RAM area”, see the memory map.
*3: The “reserved area” is basically disabled because it is used in the system.
*4: “Area used by the system” is the area set by the resistor for evaluating tool.
Notes: • For bits initialized by reset operations, the initial value set by the reset operation is listed as an initial value.
Note that the values are different from reading results.
For LPMCR/CKSCR/WDTC, there are cases in which initialization is performed or not performed,
depending on the types of the reset. The value listed is the initial value in cases where initialization is per
formed.
• The addresses following 0000FFH are reserved. No external bus access signal is generated.
• Boundary ####H between the “RAM area” and the“ reserved area” varies with the product models.
• Channels 0 to 3 of the OCU compare register use 16-bit free-run timer 2, while channels 4 to 7 of the OCU
compare register use 16-bit free-run timer 1. 16-bit free-run timer 1 is also used by input captures (ICU)
0 and 1.

■ PERIPHERALS
1. I/O Port
(1) Input/Output Port
Port 0 through A are general-purpose I/O ports having a combined function as a resource input. The I/O ports
can be used as general-purpose I/O ports only in the single-chip mode.
• Operation as output port
The pin is configured as an output port by setting the corresponding bit of the DDR register to “1”.
Writing data to PDR register when the port is configured as output, the data is retained in the output latch in
the PDR and directly output to the pin.
The value of the pin (the same value retained in the output latch of PDR) can be read out by reading the PDR
register.
Note: When a read-modify-write type instruction (e.g. bit set instruction) is performed to the port data register,
the destination bit of the operation is set to the specified value, not affecting the bits configured by the
DDR register for output. However, values of bits configured as inputs by the DDR register are changed
because input values to the pins are written into the output latch. To avoid this situation, configure the
pins by the DDR register as output after writing output data to the PDR register when switching the bit
used as input to output.
• Operation as input port
The pin is configured as input by setting the corresponding bit of the DDR register to “0.”
When the pin is configured as an input, the output buffer is turned off and the pin is put into a high-impedance
status.
When data is written into the PDR register, the data is retained in the output latch of the PDR, but pin outputs
are unaffected.
Reading the PDR register reads out the pin level (“0” or “1”).

2. Timebase Timer
The timebase timer is a 18-bit free-run counter (timebase counter) for counting up in synchronization to the
internal count clock (divided-by-2 of oscillation) with an interval timer function for selecting an interval time from
four types : 212/HCLK, 214/HCLK, 216/HCLK, and 219/HCLK.
The timebase timer also has a function for supplying operating clocks for the timer output for the oscillation
stabilization time or the watchdog timer, etc.

4. 8/16-bit PPG Timer 0, 1
The 8/16-bit PPG timer is a 2-CH re-load timer module for outputting pulse having given frequencies/duty ratios.
The two modules perform the following operation by combining functions.
• 8-bit PPG timer output 2-CH independent output mode
This is a mode for operating independent 2-CH 8-bit PPG timers, in which PG00 and PG10 pins correspond
to outputs from PPG0 and PPG1 respectively.
• 16-bit PPG timer output operation mode
In this mode, PPG0 and PPG1 are combined to be operated as a 1-CH 8/16-bit PPG timer 0 and 1 operating
as a 16-bit timer. Because outputs during 16-bit PPG timer output operation mode are reversed by an underflow
from PPG1, the same output pulses are output from PG10 and PG11 pins.
• 8 + 8-bit PPG timer output operation mode
In this mode, PPG0 is operated as an 8-bit prescaler register, in which an underflow output of PPG0 is used
as a clock source for PPG1.
A prescaler output of PPG0 is output from PG00 and PG01 pins. PPG output of PPG1 is output from PG10 and
PG11 pins.
• PPG output operation
A pulse wave with any period/duty ratio is output. The module can also be used as a D/A converter with an
external add-on circuit.

5. 16-bit Re-load Timer 0, 1 (With an Event Count Function)
The 16-bit re-load timer has an internal clock mode for counting down in synchronization to three types of internal
clocks and an event count mode for counting down by detecting a given edge of the pulse input to the external
bus pin. Either of the two functions can be selectively used.
For this timer, an “underflow” is defined as the timing of transition from the counter value of “0000H” to “FFFFH.”
According to this definition, an underflow occurs after a counter value of [re-load register setting value + 1] .
In operating the counter, the re-load mode for repeating counting operation after re-loading a counter value after
an underflow or the one-shot mode for stopping the counting operation after an underflow can be selectively used.
Because the timer can generate an interrupt upon an underflow, the timer conforms to the extended intelligent
I/O service (EI2OS).
The MB90520 series has 2 channels of 16-bit re-load timers.

6. 16-bit I/O Timer
The 16-bit I/O timer module consists of two 16-bit free-run timers, two input capture circuits (ICU), and eight
output comparators (OCU). This module allows two independent waveforms to be output on the basis of the
16-bit free-run timer. Input pulse width and external clock periods can, therefore, be measured.

(1) 16-bit Free-run Timer 1, 2
The 16-bit free-run timer consists of a 16-bit up counter, a control register and a communications prescaler
register. The value output from the timer counter is used as basic time (base timer) for input capture (ICU) and
output compare (OCU).
• A counter operation clock can be selected from four internal clocks (φ/4, φ/16, φ/64 and φ/256).
• An interrupt can be generated by overflow of counter value or compare match with OCU compare register 0
and 4. (Compare match requires mode settings.)
• The counter value can be initialized to “0000H” by a reset, software clear or compare match with OCU compare
register 0 and 4.

(2) Input Capture 0, 1 (ICU)
The input capture (ICU) generates an interrupt request to the CPU while storing the current counter value of
the 16-bit free-run timer to the ICU data register (IPCP) upon input of a trigger edge from the external pin.
There are two sets (two channels) of input capture external pins and ICU data registers, enabling measurements
of a maximum of four events.
• The input capture has two sets of external input pins (IN0, IN1) and ICU registers (IPCP), enabling
measurements of a maximum of four events.
• Trigger edge direction can be selected from rising/falling/both edges.
• The input capture can be set to generate an interrupt request at the storage timing of the counter value of the
16-bit free-run timer to the ICU data register (IPCP).
• The input compare conforms to the extended intelligent I/O service (EI2OS).
• The input capture ( ICU) function is suited for measurements of intervals (frequencies) and pulse-widths.

(3) Output Compare 0, 1 (OCU)
The output compare (OCU) is two sets of compare units each consisting of an eight-channel OCU compare
register, a comparator and a control register.
An interrupt request can be generated for each channel upon a match detection by performing time-division
comparison between the OCU compare data register setting value and the counter value of the 16-bit free-run
timer.
The OUT pin can be used as a waveform output pin for reversing output upon a match detection or a generalpurpose output port for directly outputting the setting value of the CMOD bit.

10. DTP/External Interrupt Circuit
The DTP (Data Transfer Peripheral), which is located between the peripheral circuit outside the device and the
F2MC-16LX CPU, receives an interrupt request or DMA request generated by the external peripheral circuit*
for transmission to the F2MC-16LX CPU. It is used to activate the intelligent I/O service or interrupt processing.
As with request levels, two types of “H” and “L” can be selected for the intelligent I/O service. Rising and falling
edges as well as “H” and “L” can be selected for an external interrupt request.
* : The external peripheral circuit is connected outside the MB90520 series device.

The DIRR is the register used to control delay interrupt request generation/cancellation. Programming this
register with “1” generates a delay interrupt request. Programming this register with “0” cancels a delay interrupt
request. Upon a reset, an interrupt is canceled. The undefined bit area can be programmed with either “0” or
“1.” For future extension, however, it is recommended that bit set and clear instructions be used to access this
register.

13. 8/10-bit A/D Converter
The 8/10-bit A/D converter converts analog voltage input to the analog input pins (input voltage) to digital values
(A/D conversion) and has the following features:
• Minimum conversion time: minimum 15.0 µs (at machine clock frequency of 16 MHz, including sampling time)
• Minimum sampling period: 4 µs/8 µs (at machine clock frequency of 16 MHz)
• Compare time: 99/176 machine cycles per channel
(99 machine cycles are used for a machine clock frequency below 10 MHz.)
• Conversion method: RC successive approximation method with a sample and hold circuit
• 8/10-bit resolution
• Analog input pins: Selectable from eight channels by software
Single conversion mode: Selects and converts one channel.
Scan conversion mode: Converts two or more successive channels. Up to eight channels can be programmed.
Continuous conversion mode: Repeatedly converts specified channels.
Stop conversion mode: Stops conversion after completing a conversion for one channel and wait for the
next activation (conversion can be started synchronously).
• Interrupt requests can be generated and the extended intelligent I/O service (EI2OS) can be started after the
end of A/D conversion. Furthermore, A/D conversion result data can be transferred to the memory, enabling
efficient continuous processing.
• When interrupts are enabled, there is no loss of data even in continuous operations because the conversion
data protection function is in effect.
• Starting factors for conversion: Selectable from software activation, external trigger (falling edge) and timer
(rising edge).

18. Address Match Detection Function
When the address is equal to a value set in the address detection register, the instruction code loaded into the
CPU is replaced forcibly with the INT9 instruction code (01H). As a result, when the CPU executes a set
instruction, the INT9 instruction is executed. Processing by the INT#9 interrupt routine allows the program
patching function to be implemented.
Two address detection registers are supported. An interrupt enable bit is prepared for each register. If the value
set in the address detection register matches an address and if the interrupt enable bit is set at “1,” the instruction
code loaded into the CPU is replaced forcibly with the INT9 instruction code.

20. Low-power Consumption (Stand-by) Mode
The F2MC-16LX has the following CPU operating modes configured by selection of an operating clock and clock
operation control.
• Clock mode
PLL clock mode : A mode in which the CPU and peripheral equipment are driven by PLL-multiplied oscillation
clock.
Main clock mode: A mode in which the CPU and peripheral equipment are driven by drivided-by-2 of the
oscillation clock. The PLL multiplication circuits stops in the main clock mode.
• Sub-clock mode
The sub-clock mode causes the CPU to operate only with the sub-clock. This mode uses the sub-clock
frequency divided by four as the operating clock frequency while stopping the main clock and PLL clock.
• CPU intermittent operation mode
The CPU intermittent operation mode is a mode for reducing power consumption by operating the CPU
intermittently while external bus and peripheral functions are operated at a high speed.
• Hardware stand-by mode
The hardware standby mode is a mode for reducing power consumption by stopping clock supply to the CPU
by the low-power consumption control circuit (sleep mode), stopping clock supplies to the CPU and peripheral
functions (timebase timer mode), and stopping oscillation clock (stop mode, hardware stand-by mode). Of
these modes, modes other than the PLL clock mode are low power consumption modes.

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 when the PLL clock is not in use. If the voltage drops 1 V or less per
second, however, the PLL clock may be used.

6. A/D Converter Glossary
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 for A/D Conversion
Analog inputs should have external circuit impedance of approximately 5 kΩ or less.
External capacitance, if used, should be several thousand times the level of the chip’s internal capacitance in
consideration of the effects of partial potential between the external and internal capacitance.
If the impedance of the external circuit is too high, the analog voltage sampling interval may be insufficient (using
a sampling interval of 4.00 µs and a machine clock frequency of 16 MHz).
• Block diagram of analog input circuit model

RON: Approx. 1.5 kΩ
C: Approx. 30 pF
MB90F523
RON: Approx. 3.0 kΩ
C: Approx. 65 pF
Note: Listed values must be considered standards.
• Error
The smaller | AVRH – AVRL | is, the greater the error is.
