■ HANDLING DEVICES
Take note of the following points when handling devices :
• Do not exceed maximum rated voltage (to prevent latch-up)
• Supply voltage stability
• Power-on precautions
• Power supply pins
• Crystal oscillator circuit
• Notes on using an external clock
• Precautions when not using sub-clock mode
• Treatment of unused pins
• Treatment of N.C. pins
• Treatment of pins when A/D converter is not used
• Sequence for connecting and disconnecting the A/D converter power supply and analog input pins
• Shared use of general-purpose I/O ports and LCD controller/driver SEG/COM pins
• Conditions when output from ports 0 and 1 is undefined
• Initialization
• Notes on using the DIV A, Ri and DIVW A, RWi instructions
• Notes on using REALOS
Device Handling Precautions
• Do not exceed maximum rated voltage (to prevent latch-up)
Latch-up occurs in CMOS ICs if a voltage greater than VCC or less than VSS is applied to an input or output pin
(other than a high or medium withstand voltage pin) or if the voltage applied between VCC and VSS exceeds
the rating. If latch-up occurs, the power supply current increases rapidly resulting in thermal damage to circuit
elements. Therefore, ensure that maximum ratings are not exceeded in circuit operation.
Similarly, when turning the analog power supply on or off, ensure the analog power supply voltages (AVCC,
AVRH, DVCC) and analog input voltages do not exceed the digital voltage (VCC) .
Also ensure that the voltages applied to the LCD power supply pins (V3 to V0) do not exceed the power supply
voltage (VCC) .
• Supply voltage stability
Rapid changes in supply voltage may cause the device to misoperate, even if the voltage remains within the
allowed operating range. Accordingly, ensure that the VCC supply is stable.
The standard for power supply voltage stability is a peak-to-peak VCC ripple voltage at the mains supply
frequency (50 to 60 Hz) of 10% or less of VCC and a transient voltage change rate of 0.1 V/ms or less when
turning the power supply on or off.
• Power-on precautions
To prevent misoperation of the internal regulator circuit at power-on, ensure that the power supply rising time
(0.2 V to 2.7 V) is at least 50 µs.
• Power supply pins
When multiple VCC and VSS pins are provided, connect all VCC and VSS pins to power supply or ground externally.
Although pins at the same potential are connected together in the internal device design so as to prevent
misoperation such as latch-up, connecting all VCC and VSS pins appropriately minimizes unwanted radiation,
prevents misoperation of strobe signals due to increases in the ground level, and keeps the overall output
current rating.
Also, ensure that the impedance of the VCC and VSS connections to the power supply are as low as possible.
18
DS07-13707-5E
MB90520B Series
Connection of a bypass capacitor of approximately 0.1 µF between VCC and VSS is recommended to prevent
power supply noise. Connect the capacitor close to the VCC and VSS pins.
• Crystal oscillator circuit
Noise on the X0 and X1 pins can be a cause of device misoperation. Place the X0 and X1 pins, crystal oscillator
(or ceramic oscillator) , and bypass capacitor to ground as close together as possible. Also, design the circuit
board so that the X0 and X1 pin wiring does not cross other wiring.
Surrounding the X0/X1 and X0A/X1A pins with ground in the printed circuit board design is recommended to
ensure stable operation.
• Notes on using an external clock
When using an external clock, drive the X0 pin only and leave the X1 pin open.
The figure below shows an example of how to use an external clock.

Open circuit
X1
MB90520B series
• Precautions when not using sub-clock mode
Connect an oscillator to X0A and X1A, even if not using sub-clock mode.
• Treatment of unused pins
Leaving unused input pins unconnected can cause misoperation or permanent damage to the device due to
latchup. Always pull-up or pull-down unused pins using a 2 kΩ or larger resistor.
If some I/O pins are unused, either set as outputs and leave open circuit or set as inputs and treat in the same
way as input pins.
• Treatment of N.C. pins
Always leave N.C. (non connect) pins open circuit.
• Treatment of pins when A/D converter not used
When not using the A/D converter and D/A converter, always connect AVCC = DVCC = AVRH = VCC and AVSS =
AVRL = VSS.
• Sequence for connecting and disconnecting the A/D converter power supply and analog input pins
Do not apply voltage to the A/D and D/A converter power supply (AVCC, AVRH, AVRL, DVCC, DVSS) or analog
inputs (AN0 to AN7) until the digital power supply (VCC) is turned on.
When turning the device off, turn off the digital power supply after disconnecting the A/D converter power
supply and analog inputs. When turning the power on or off, ensure that AVRH and DVCC do not exceed AVCC
(turning the analog and digital power supplies on and off simultaneously is OK) .
• Shared use of general-purpose I/O ports and LCD controller/driver SEG/COM pins
The SEG08 to SEG31 and COM0 to COM3 pins are shared with general-purpose I/O ports. The electrical
ratings for SEG08 to SEG23 and COM0 to COM3 are the same as for CMOS outputs and the electrical ratings
for SEG24 to SEG31 are the same as for N-ch open-drain ports.
DS07-13707-5E

MB90520B Series
• Conditions when output from ports 0 and 1 is undefined
After turning on the power supply, the outputs from ports 0 and 1 are undefined during the oscillation stabilization delay time controlled by the regulator circuit (during the power-on reset) . The figure below shows the
timing.
Note that this undefined output period does not occur on products without an internal regulator circuit as these
products do not have an oscillation stabilization delay time.

(approx. 16.38 ms for a 16 MHz oscillation clock frequency)
Note : See the “■ PRODUCT LINEUP” section for details of which MB90520B series products have an internal
regulator circuit.
• Initialization
The device contains internal registers that are only initialized by a power-on reset. To initialize these registers,
restart the power supply.
• Notes on using the DIV A, Ri and DIVW A, RWi instructions
Set the corresponding bank registers (DTB, ADB, USB, SSB) to “00H” when using the signed division instructions “DIV A, Ri” and “DIVW A, RWi”.
If the corresponding bank registers (DTB, ADB, USB, SSB) are set to other than “00H”, the remainder value
produced by the instruction is not stored in the instruction operand register.
• Notes on using REALOS
The extended intelligent I/O service (EI2OS) cannot be used when using REALOS.
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.

* : The values of addresses #1, #2, and #3 vary by product.
Note : The upper part of 00 bank contains a mirror of the ROM data in FF bank. This is called the mirror ROM
function and enables use of the C compiler’s small memory model. As the lower 16 bits of the FF bank and
00 bank addresses are the same, tables located in ROM can be referenced without needing to declare far
pointers.
For example, accessing 00C000H actually accesses the contents of ROM at FFC000H. Note that, as the FF
bank ROM area exceeds 48 KBytes, the entire ROM image cannot be mirrored in 00 bank. Accordingly, as
ROM data from FF4000H to FFFFFFH is mirrored in 004000H to 00FFFFH, always locate ROM data tables in
the range FF4000H to FFFFFFH.

*3 : “ (Reserved areas) ” are addresses used internally by the system and may not be used.
*4 : The “ (Area reserved for system use) ” contains setting registers used by the evaluation tools.
Notes : • LPMCR, CKSCR, and WDTC are initialized by some types of reset and not by others. The initial values
listed are for the case when the registers are initialized.
• The boundary address “####H” between the “ (RAM area) ” and “ (Reserved area) ” differs depending on
the product. See the “■ MEMORY MAP” section for details.
• OCU compare registers ch.0 to ch.3 use 16-bit freerun timer 0 and OCU compare registers ch.4 to ch.7
use 16-bit freerun timer 1. Note that 16-bit freerun timer 0 is also used by input capture 0 and 1 (ICU) .

■ PERIPHERAL RESOURCES
1. I/O Ports
• The I/O ports can be used as general-purpose I/O ports (parallel I/O ports) . The MB90520B series have 11
ports (85 pins) . The ports share pins with the inputs and outputs of the peripheral functions.
• The port data registers (PDR) are used to output data to the I/O pins and capture the input signals from the
I/O ports.
Similarly, the port direction registers (DDR) set the I/O direction (input or output) for each individual port bit.
• The following tables list the I/O ports and peripheral functions with which they share pins.

Notes
• Port 9 contains general-purpose I/O ports with N-ch open-drain output circuits.
• Connect an external pull-up resistor when using port 9 pins as outputs.
• Port 6 shares pins with the analog inputs. When using port 6 as a general-purpose port, ensure that the
corresponding analog input enable register (ADER) bits are set to “0”. ADER is initialized to “FFH” after a reset.

2. Timebase Timer
• The timebase timer is an 18-bit freerun timer (timebase timer/counter) that counts up synchronized with the
main clock (oscillation clock : HCLK divided by 2) .
• The timer can generate interrupt requests at a specified interval, with four different interval time settings
available.
• The timer supplies the operating clock for peripheral functions including the oscillation stabilization delay timer
and watchdog timer.
• Timebase timer interval settings
Internal Count Clock Period

3. Watchdog Timer
• The watchdog timer is a timer/counter used to detect faults such as program runaway.
• The watchdog timer is a 2-bit counter that counts the clock signal from the timebase timer or clock timer.
• Once started, the watchdog timer must be cleared before the 2-bit counter overflows. If an overflow occurs,
the CPU is reset.
• Interval time for the watchdog timer

* : The difference between the maximum and minimum watchdog timer interval times is due to the timing when the
counter is cleared.
* : As the watchdog timer is a 2-bit counter that counts the carry-up signal from the timebase timer or clock timer,
clearing the timebase timer (when operating on HCLK) or the clock timer (when operating on SCLK) lengthens
the time until the watchdog timer reset is generated.

5. 16-bit Reload Timers 0 and 1 (With Event Count Function)
The 16-bit reload timers have the following functions.
• The count clock can be selected from three internal clock and the external event clock.
• Either software trigger or external trigger can be selected as the start signals for 16-bit reload timers 0 and 1.
• An interrupt to the CPU can be generated when an underflow occurs on 16-bit reload timer 0 and 1. This
interrupt allows the timers to be used as interval timers.
• Two different operation modes can be selected when an underflow occurs on 16-bit reload timer 0 and 1 : oneshot mode in which timer operation halts when an underflow occurs or reload mode in which the reload register
value is loaded into the timer and counting continues.
• Extended intelligent I/O service (EI2OS) is supported.
• The MB90520B series contains two 16-bit reload timer channels.
• 16-bit reload timer operation modes

6. 16-bit I/O Timers
The 16-bit I/O timers consist of a two-channel 16-bit freerun timer, two-channel input capture, and eight-channel
output compare. The output compare channels can be used to generate eight independent waveform outputs
based on the 16-bit freerun timer. The input capture channels can be used to measure input pulse widths and
external clock periods.

⎯
• 16-bit freerun timer functions
• The count value for the 16-bit freerun timer sets the base time for the input capture and output compare
functions.
• An interrupt can be generated when the 16-bit freerun timer overflows.
• Extended intelligent I/O service (EI2OS) can be generated.
• 16-bit freerun timers 0 and 1 can be cleared to “0000H” when an external reset is input, on setting the timer
clear bit (TCCS : CLR = 1) , and when a compare match occurs on output compare 0 to 4.
• The count clock frequency can be selected from the following four clocks :
4/φ (250 ns) , 16/φ (1.0 µs) , 64/φ (4.0 µs) , 256/φ (16.0 µs)
Note : φ is the machine clock frequency. The values in ( ) are for 16 MHz machine clock.
• Input capture functions
• The input capture saves the value of the 16-bit freerun timer and generates an interrupt request when the
specified edge is detected on the trigger input from the external trigger input pin (IN00 or IN01/IN10 or IN11) .
• Input capture channels 0 and 1 can perform input capture and generate interrupt request independently.
• Extended intelligent I/O service (EI2OS) can be generated.
• Detection of rising edges, falling edges, or either edge can be selected as the trigger edge.
• When using input capture 0, either the IN00 or IN01 pin can be used. Note, however, that masking one pin
only is not possible.
• When using input capture 1, either the IN10 or IN11 pin can be used. Note, however, that masking one pin
only is not possible.
• Output compare functions
• The output compare channels compare the values set in output compare registers 0 to 7 with the 16-bit freerun
timers 0 and 1 count values and invert the level of the corresponding output compare pin and clear the 16-bit
freerun timer to “0000H” when a match is detected.
• Extended intelligent I/O service (EI2OS) can be generated.
• The initial output levels at the output compare pins can be set after the microcontroller boots.
• The output levels from the eight output compare channels are controlled independently. Similarly, interrupt
requests are also generated independently by each channel.

Sudden changes in the power supply voltage may cause a power-on reset.
The recommended practice if you wish to change the power supply voltage while the device is operating is
to raise the voltage smoothly as shown below. Also, changes to the supply voltage should be performed when
the PLL clock is not in use. The PLL clock may be used, however, if the rate of voltage change is 1 V/s or less.

6. A/D Converter Glossary
Resolution
Linearity error
: The change in analog voltage that can be recognized by the A/D converter.
: The deviation between the actual conversion characteristics and the line linking the
zero transition point (“00 0000 0000B” ←→ “00 0000 0001B”) and the full scale transition point (“11 1111 1110B” ←→ “11 1111 1111B”) .
Differential linearity error : The variation from the ideal input voltage required to change the output code by 1 LSB.
Total error
: The total error is the difference between the actual value and the theoretical value.
This includes the zero-transition error, full-scale transition error, and linearity error.

7. Notes for A/D Conversion
The recommended external circuit impedance of analog inputs for MB90V520 is approximately 5 kΩ or less,
that for MB90F523B is approximately 15.5 kΩ or less, and that for MB90522B/523B is approximately 10 kΩ or
less.
If using an external capacitor, the capacitance should be several thousand times the level of the chip’s internal
capacitor to allow for the 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 too short. (for
sampling time = 4 µs, machine clock frequency = 16 MHz) .
• Block diagram of analog input circuit model

Note : The values listed are an indication only.
• Error
The relative error increases as |AVRH − AVRL| becomes smaller.
