MB90822/F822/F823/V820
■ DESCRIPTION
The MB90820 series is a line of general-purpose, Fujitsu 16-bit microcontrollers designed for process control
applications which require high-speed real-time processing, such as consumer products.
While inheriting the AT architecture of the F2MC* family, the instruction set for the F2MC-16LX CPU core of the
MB90820 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 MB90820 series has an on-chip 32-bit accumulator which
enables processing of long-word data.
The peripheral resources integrated in the MB90820 series include : an 8/10-bit A/D converter, 8-bit D/A converters, UARTs (SCI) 0, 1, multi-functional timer (16-bit free-running timer, input capture units (ICUs) 0 to 3, output
compare units (OCUs) 0 to 5, 16-bit PPG timer 0, waveform generator), 16-bit PPG timer 1, 2, PWC 0, 1, 16-bit
reload timer 0, 1 and DTP/external interrupt.
*: F2MC stands for FUJITSU Flexible Microcontroller, a registered trademark of FUJITSU LIMITED.

■ 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 MB90V820 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 MB90V820, images from FF8000H to FFFFFFH are mapped to bank 00, and FE0000H to FF7FFFH are
mapped to bank FE and bank FF only. (This setting can be changed by configuring the development tool.)
• In the MB90822/F822/F823, images from FF8000H to FFFFFFH are mapped to bank 00, and FF0000H to
FF7FFFH are mapped to bank FF only. In the MB90F823, images from FF8000H to FFFFFFH are mapped to
bank 00, and FE0000H to FF7FFFH are mapped to bank FE and bank FF only.

■ HANDLING DEVICES
1. Preventing latch-up
CMOS ICs may cause latch-up in the following situations:
• When a voltage higher than VCC or lower than VSS is applied to input or output pins.
• When a voltage exceeding the rating is applied between VCC and VSS.
• When the AVCC power supply is applied before the VCC voltage.
If latch-up occurs, the power supply current increases rapidly, sometimes resulting in thermal breakdown of 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 exceed the digital power-supply
voltage.
2. Handling unused pins
Unused input pins left open may cause abnormal operations, or latch-up leading to permanent damage. Unused
input pins should be pulled up or pulled 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.
If any output pins are unused, set them to open.
3. Use of the external clock
To use an external clock, drive only the X0 pin and leave the X1 pin open (See the illustration below).

X1
4. Power supply pins (VCC/VSS)
In products with multiple VCC or VSS pins, the pins of the same potential are internally connected in the device
to avoid abnormal operations including latch-up. However, you must connect the pins to external power supply
and a 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 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.
5. Crystal oscillator circuit
Noise near the X0 and X1 pins may cause the device to malfunction. Design the printed circuit board so that
X0, X1, 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 and X1 pins surrounded by ground plane
because stable operation can be expected with such a layout.
6. Turning-on sequence of power supply to A/D converter and D/A converter
Make sure to turn on the A/D converter and D/A converter power supply (AVCC, AVSS, AVR) and analog inputs
(AN0 to AN15) after turning-on the digital power supply (VCC).
16
MB90820 Series
Turn-off the digital power after turning off the A/D converter and D/A converter supply and analog inputs. In this
case, make sure that the voltage of AVR does not exceed AVCC (turning on/off the analog and digital power
supplies simultaneously is acceptable).
7. Connection of unused pins of A/D converter and D/A converter
When the A/D converter and D/A converter are not used, connect the pins as follows: AVCC = VCC, AVSS =
AVR = VSS.
8. N.C. pin
The N.C. (internally connected) pin must be opened for use.
9. Notes on energization
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at
50 µs or more.
10. Initialization
In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers
turning on the power again.
11. Return from standby state
If the power supply voltage goes below the standby RAM holding voltage in the standby state, the device may
fail to return from the standby state. In this case, reset the device via the external reset pin to return to the normal
state.

Note: The ROM data of bank FF is reflected to the upper address of bank 00, realizing effective use of the C
compiler small model. The lower 16-bit is 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 accessed actually. Since the ROM area of the FF bank exceeds 32K bytes, the
whole area cannot be reflected in the image for the 00 bank. The ROM data at FF8000H to FFFFFFH looks,
therefore, as if it were the image for 008000H to 00FFFFH. Thus, it is recommended that the ROM data table
be stored in the area of FF8000H to FFFFFFH.

■ PERIPHERAL RESOURCES
1. Low-power Consumption Control Circuit
The MB90820 series has the following CPU operating mode configured by selection of an operating clock and
clock operation control.
• Clock mode
PLL clock mode : A PLL clock that is a multiple of the oscillation clock (HCLK) frequency is used to operate
the CPU and peripheral functions.
Main clock mode : The main clock, with a frequency one-half that of the oscillation clock (HCLK), is used to
operate the CPU and peripheral functions. In main clock mode, the PLL divide circuit
is inactive.
• CPU intermittent operation mode
CPU intermittent operation mode causes the CPU to operate intermittently, while high-speed clock pulses are
supplied to peripheral functions, reducing power consumption. In CPU intermittent operation mode, clock
pulses are supplied intermittently to the CPU when it is accessing a register, internal memory, a peripheral
function, or an external unit.
• Standby mode
In standby mode, the low power consumption control circuit reduces power consumption by stopping;
• The supply of the clock to CPU (sleep mode)
• CPU and peripheral functions (timebase timer mode)
• The oscillation clock itself (stop mode)
• PLL sleep mode
PLL sleep mode is activated to stop the CPU operating clock when the microcontroller enters PLL clock mode;
other components continue to operate on the PLL clock.
• Main sleep mode
Main sleep mode is activated to stop the CPU operating clock when the microcontroller enters main clock
mode; other components continue to operate on the main clock.
• PLL timebase timer mode
PLL timebase timer mode causes microcontroller operation, with the exception of the oscillation clock, PLL
clock and timebase timer, to stop. All functions other than the timebase timer are deactivated.
• Main timebase timer mode
Main timebase timer mode causes microcontroller operation, with the exception of the oscillation clock, main
clock and the timebase timer, to stop. All functions other than the timebase timer are deactivated.
• Stop mode
Stop mode causes the source oscillation to stop. All functions are deactivated.

2. I/O Ports
(1) Outline of I/O ports
Each I/O port outputs data from CPU to I/O pins or inputs signals from I/O pins to CPU through port data register
(PDR). Direction of the data flow (input or output) for each I/O pin can be designated in bit unit by port data
direction register (DDR). The function of each port and the resource I/O multiplexed with it are described below:

5. 16-bit reload timer (x 2)
The 16-bit reload timer provides two operating mode, internal clock mode and event count mode. In each
operating mode, the 16-bit down counter can be reloaded (reload mode) or stopped by underflow (one-shot
mode).
Output pins TO1 and TO0 are able to output different waveform according to the counter operating mode. TO1
and TO0 toggles when counter underflows if counter is operated as reload mode. TO1 and TO0 output specified
level (H or L) during counting if the counter is in one-shot mode.
Features of the 16-bit reload timer :
• Interrupt when timer underflows
• Supports for EI2OS
• Internal clock operating mode :
Three internal count clocks can be selected.
Counter can be activated by software or external trigger (signal at TIN1 and TIN0 pins).
Counter can be reloaded or stopped when underflow after activated.
• Event count operating mode :
Counter counts down one by one with specified edge at TIN1 and TIN0 pins.
Counter can be reloaded or stopped when underflow.

7. Multi-functional Timer
The 16-bit multi-functional timer module consists of one 16-bit free-running timer, four input capture circuits, six
output comparators and one channel of 16-bit PPG timer. This module allows six independent waveforms
generated by PPG timer or waveform generator to be outputted. With the 16-bit free-running timer and the input
capture circuit, input pulse width and external clock period measurement can be done.
(1) 16-bit free-running timer (1 channel)
• The 16-bit free-running timer consists of a 16-bit up/up-down counter, timer control status register, 16-bit
compare clear register (with buffer register) and a prescaler.
• 8 types of counter operation clock (φ, φ/2, φ/4, φ/8, φ/16, φ/32, φ/64, φ/128) can be selected. (φ is the machine
clock.)
• Two types of interrupt causes :
- Compare clear interrupt is generated when there is a comparing match with compare clear register and 16bit free-running timer.
- Zero detection interrupt is generated while 16-bit free-running timer is detected as zero in count value.
• EI2OS supported.
• Compare-clear register buffer provided :
The selectable buffer enables the 16-bit free-running timer update its compare-clear register automatically
without stop the timer operation. User can read the next compare-clear value to the compare-clear register
when the timer is running. The compare-clear register will be updated when the timer value is “0000H”
• Reset, software clear, compare match with compare clear register in up-count mode will reset the counter
value to “0000H”.
• Supply clock to output compare module :
The prescaler output is acted as the count clock of the output compare.
(2) Output compare module ( 6 channels)
• The output compare module consists of six 16-bit output compare registers (with selectable buffer register),
compare output latch and compare control registers. An interrupt is generated and output level is inverted
when the value of 16-bit free-running timer and output compare register are matched.
• 6 output compare registers can be operated independently.
• Output pins and interrupt flag are corresponding to each output compare register.
• 2 output compare registers can be paired to control the output pins.
• Inverts output pins by using 2 output compare registers together.
• Setting the initial value for each output pin is possible.
• Interrupt is generated when there is a comparing match with output compare register and 16-bit free-running
timer.
• EI2OS supported.
(3) Input capture module (4 channels)
Input capture consists of 4 independent external input pins, the corresponding input capture data register and
input capture control status register. By detecting any edge of the input signal from the external pin, the value
of the 16-bit free-running timer can be stored in the capture register and an interrupt is generated simultaneously.
• Operations synchronized with the 16-bit free-running timer’s count clock.
• 3 types of trigger edge (rising edge, falling edge and both edge) of the external input signal can be selected
and there is indication bit to show the trigger edge is rising or falling.
• 4 input captures can be operated independently.
• Two independent interrupts are generated when detecting a valid edge from external input.
• EI2OS supported.
49
MB90820 Series
(4) 16-bit PPG timer (1 channel)
The 16-bit PPG timer 0 is used to provide a PPG signal for waveform generator. (See section “6. 16-bit PPG
Timer”.)
(5) Waveform generator module
The waveform generator consists of three 16-bit timer registers, three 16-bit timer control registers and a waveform control register.
With waveform generator, it is possible to generate real time output, 16-bit PPG waveform output, non-overlap
3-phase waveform output for inverter control and DC chopper waveform output.
• It is possible to generate a non-overlap waveform output based on dead-time of 16-bit timer. (Dead-time timer
function)
• It is possible to generate a non-overlap waveform output when realtime output is operated in 2-channel mode.
(Dead-time timer function)
• By detecting realtime output compare match, GATE signal of the PPG timer operation will be generated to
start or stop PPG timer operation. (GATE function)
• When a match is detected by real time output compare, the 16-bit timer is activated. The PPG timer can be
started or stopped easily by generating a GATE signal for PPG operation until the 16-bit timer stops. (GATE
function)
• Force to stop output waveform using DTTI pin input.
• Interrupt is generated when DTTI active or 16-bit timer underflow.
• EI2OS is supported.

8. PWC Timer (x 2)
The PWC (pulse width count) timer is a 16-bit multi-functional up counter with reload timer functions and input
signal pulse width count functions.
The PWC timer consists of a 16-bit counter, an input pulse divider, a division ratio control register, a count input
pin, a pulse output pin, and a 16-bit control register.
The PWC timer has the following features:
• Interruption is generated when timer overflow or end of PWC measurement.
• EI2OS is supported.
• Timer functions :
- Generates an interrupt request at set time intervals.
- Outputs pulse signals synchronized with the timer cycle.
- Selects the counter clock from three internal clocks.
• Pulse-width count functions:
- Counts the time between external pulse input events.
- Selects the counter clock from three internal clocks.
- Count mode:
• H pulse width (rising edge to falling edge) / L pulse width (falling edge to rising edge)
• Rising-edge cycle (rising edge to falling edge) / Falling-edge cycle (falling edge to rising edge)
• Count between edges (rising or falling edge to falling or rising edge)
Capable of counting cycles by dividing input pulses by 22, 24, 26, 28 using an 8-bit input divider.
Generates an interrupt request upon the completion of count operation.
Selects single or consecutive count operation.

10. DTP/External Interrupts
The DTP/external interrupt circuit is activated by the signal supplied to a DTP/external interrupt pin. The CPU
accepts the signal using the same procedure it uses for normal hardware interrupts and generates external
interrupts or activates the extended intelligent I/O service (EI2OS).
Features of DTP/External Interrupt :
• Total 8 external interrupt channels.
• Two request levels (“H” and “L”) are provided for the intelligent I/O service.
• Four request levels (rising edge, falling edge, “H” level and “L” level) are provided for external interrupt requests.

12. A/D Converter
The A/D converter converts the analog voltage input (input voltage) to an analog input pin to a digital value. It
has the following features :
• The minimum conversion time is 3 µs (for a machine clock of 24 MHz; including sampling time).
• The converter uses the RC-type successive approximation conversion method with a sample and hold circuit.
• A resolution of 10 bits or 8 bits can be set.
• Up to 16 channels for analog input pins can be selected by a program.
• Various conversion mode :
- Single conversion mode : Selectively convert one channel.
- Scan conversion mode : Continuously convert multiple channels. Maximum of 16 selectable channels.
- Continuous conversion mode : Repeatedly convert specified channels.
- Stop conversion mode : Convert one channel then halt until the next activation (enables synchronization of
the conversion start timing).
• At the end of A/D conversion, an interrupt request can be generated and EI²OS can be activated.
• In the interrupt-enabled state, the conversion data protection function prevents any part of the data from being
lost through continuous conversion.
• The conversion can be activated by software, 16-bit reload timer 1 (rising edge) and 16-bit free-running timer
zero detection edge.

13. D/A Converter
The D/A converter is used to generate an analog output from an 8-bit digital input. By setting the enable bit in
the D/A control register (DACR) to 1, it will enable the corresponding D/A output channel. Hence, setting this bit
to 0 will disable that channel.
If D/A output is disabled, the analog switch inserted to the output of each D/A converter channel in series is
turned off. In the D/A converter, the bit is cleared to 0 and the direct-current path is shut off. The above is also
true in the stop mode.
The output voltage of the D/A converter ranges from 0 V to 255/256 x AVCC. To change the output voltage range,
adjust the AVCC voltage externally.
The D/A converter output does not have the internal buffer amplifier. The analog switch (= 100 Ω) is inserted to
the output in series. To apply load to the output externally, estimate a sufficient stabilization time.
Table below lists the theoretical values of output voltage of the D/A converter.

14. ROM Correction Function
When the corresponding address matches the value set in the address detection register, the instruction code
to be loaded into the CPU is forced to be replaced with the INT9 instruction code (01H). When executing a set
instruction, the CPU executes the INT9 instruction. The address detection function is implemented by processing
using the INT9 instruction routine.
The device contains two address detection registers, each provided with a compare enable bit. When the value
set in the address detection register matches an address and the interrupt enable bit is “1”, the instruction code
to be loaded into the CPU is forced to be replaced with the INT9 instruction code.

16. 512/1024 Kbit Flash Memory
The 512K bits flash memory is allocated in the FFH banks on the CPU memory map.
The 1024K bits flash memory is allocated in the FEH and FFH banks on the CPU memory map.
Like MaskROM, flash memory is read-accessible and program-accessible to the CPU using the flash memory
interface circuit. The flash memory can be programmed/erased by the instruction from the CPU via the flash
memory interface circuit. The flash memory can therefore be reprogrammed (updated) while still on the circuit
board under integrated CPU control, allowing program code and data to be improved efficiently.
Note that sector operations such as “enable sector protect” cannot be used.
Features of 512/1024K bits flash memory
• 64K x 8 bits/32K x 16 bits (32K + 8K x 2 + 16K) sector configuration for 512K bits flash memory
• 128K x 8 bits/64K x 16 bits (64K + 32K + 8K x 2 + 16K) sector configuration for 1024K bits flash memory
• Automatic program algorithm (same as the Embedded Algorithm* : MBM29F400TA)
• Installation of the deletion temporary stop/delete restart function
• Write/delete completion detected by the data polling or toggle bit
• Write/delete completion detected by the CPU interrupt
• Compatibility with the JEDEC standard-type command
• Each sector deletion can be executed (sectors can be freely combined)
• Flash security function
• Number of write/delete operations are guaranteed 10,000 times.

Applicable to pins: P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50, P51, P80 to P87.
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.
77
MB90820 Series
• 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 operate the power-on reset.
• Care must be taken not to leave the +B input pin open.
• Note that analog system input/output pins (LCD drive pins and comparator input pins, etc.) other than the
A/D input pins cannot accept +B input.

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/s, however, you can use the PLL clock.

Resolution
Non linearity error
: Analog variation that is recognized by an A/D converter.
: Deviation between a line across zero-transition line (“00 0000 0000”↔
“00 0000 0001”) and full-scale transition line (“11 1111 1110”↔“11 1111 1111”) and
actual conversion characteristics.
Differential linearity error : Deviation of input voltage, which is required for changing output code by 1 LSB, from
an ideal value
Total error
: Difference between an actual value and an ideal value. Atotal error includes zero
transition error, full-scale transition error, and linear 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 sample and hold capacitor is insufficient, adversely affecting
A/D conversion precision.
• Analog input circuit model

Note : The values are reference values.
• 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.
• The relationship between the external impedance and minimum sampling time
