F2MC-16LX MB90580C Series
MB90583C/583CA/F583C/F583CA/587C/587CA/V580B
■ DESCRIPTION
The MB90580C 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*1 family, the instruction set for the F2MC-16LX CPU core of the
MB90580C 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 MB90580C has an on-chip 32-bit accumulator which
enables processing of long-word data.
The peripheral resources integrated in the MB90580C series include: an 8/10-bit A/D converter, an 8-bit D/A
converter, UARTs (SCI) 0 to 4, an 8/16-bit PPG timer, 16-bit I/O timers (16-bit free-run timer, input capture units
(ICUs) 0 to 3, output compare units (OCUs) 0 and 1), and an IEBusTM controller *2.

■ 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 MB90V580B 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 MB90V580B, images from FF4000H to FFFFFFH are mapped to bank 00, and FE0000H to FF3FFFH to
mapped to bank FE and FF only. (This setting can be changed by configuring the development tool.)
• In the MB90583C/583CA/587C/587CA/F583C/F583CA, images from FF4000H to FFFFFFH are mapped to
bank 00, and FF0000H to FF3FFFH to bank FF only.
IEBusTM Controller
• MB90587C/CA does not have an IEBusTM Controller.

■ HANDLING DEVICES
1. Preventing Latchup
CMOS ICs may cause latchup 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 AVcc power is supplied prior to the Vcc voltage.
If latchup occurs, the power supply current increases rapidly, sometimes resulting in thermal breakdown of the
device. Use meticulous care not to let it occur.
For the same reason, also be careful not to let the analog power-supply voltage exceed the digital power-supply
voltage.
2. Handling unused input 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 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.
3. Treatment of the TX and RX pins with the IEBusTM unused
When the IEBus is not used, connect a pull-down resistor to the TX pin and a pull-down/pull-up resistor to the
RX pin.
4. Use of the external clock
When the device uses an external clock, drive only the X0 pin while leaving the X1 pin open (See the illustration
below).
MB90580C series
X0
Open
X1
5. Power Supply Pins (VCC/VSS)
In products with multiple VCC or VSS pins, the pins of a same potential are internally connected in the device to
avoid abnormal operations including latch-up. However, connect the pins external power 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.
19
MB90580C Series
It is recommended to provide a bypass capacitor of around 0.1 µF between VCC and VSS pin near the device.

Series

6. Crystal Oscillator Circuit
Noises around X0 or X1 pins may be possible causes of abnormal operations. Make sure to provide bypass
capacitors via shortest distance from X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines, and
make sure, to the utmost effort, that lines of oscillation circuit not cross the lines of other circuits.
It is highly recommended to provide a printed circuit board art work surrounding X0 and X1 pins with an grand
area 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 (AVCC, AVSS, AVRH, AVRL) 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 the voltage of AVRH dose not exceed AVCC (turning on/off the analog and digital power supplies simultaneously is acceptable).
8. Connection of Unused Pins of A/D Converter
Connect unused pin of A/D converter to AVCC = VCC, AVSS = AVRH = AVRL = VSS.
9. Connection of Unused Pins of D/A Converter
Connect unused pin of D/A converter to DVRH = VSS, DVSS = VSS.
10. N.C. Pin
The N.C. (internally connected) pin must be opened for use.
11. 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).
12. Use of the sub-clock
Use the one clock system parts when the sub-clock is not used. Connected the oscillator under 32 kHz to the
both terminals XA0 and X1A for the two clocks system parts. Pull-down the terminal X0A and leave the terminal
X0A open for the one clock system parts.
20
MB90580C Series
13. Indeterminate outputs from ports 0 and 1
The outputs from ports 0 and 1 become indeterminate during a power-on reset after the power is turned on.
Pay attention to the port output timing shown as follow.
Oscillation settling time*2
Power-on reset*1
VCC (Power-supply pin)
PONR (power-on reset) signal
RST (external asynchronous reset) signal
RST (internal reset) signal
Oscillation clock signal
KA (internal operation clock A) signal
KB (internal operation clock B) signal
PORT (port output) signal
Period of indeterminate
*1: Power-on reset time: Period of “clock frequency x 217” (Clock frequency of 16 MHz: 8.192 ms)
*2: Oscillation settling time: Period of “clock frequency x 218” (Clock frequency of 16 MHz: 16.384 ms)
14. 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.
15. 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.
16. Precautions for Use of ’DIV A, Ri,’ and ’DIVW A, RWi’ 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.
17. Precautions for Use of REALOS
Extended intelligent I/O service (EI2OS) cannot be used, when REALOS is used.
21
MB90580C Series
18. Caution on 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.

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 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 48 Kbytes, 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.

• Explanation of initial values→“0” : initial value“0” / “1” : initial value“1” / “X” : undefined / “−” : undefined (not used)
• The addresses following 00FFH are reserved. No external bus access signal is generated.
• Boundary #H between the RAM area and the reserved area varies with the product model.
Note: For bits that is initialized by an reset operation, 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
where initialization is performed or not performed, depending on the types of the reset. However initial value
for resets that initializes the value are listed.

I/O Ports
(1) Outline of I/O ports
When a data register serving for control output is read, the data output from it as a control output is read regardless
of the value in the direction register. Note that, if a read modify write instruction (such as a bit set instruction)
is used to preset output data in the data register when changing its setting from input to output, the data read
is not the data register latched value but the input data from the pin.
Ports 0 to 4 and 6 to A are input/output ports which serve as inputs when the direction register value is “0” or
as outputs when the value is “1”.
On the MB90580C series, ports 0 to 3 also serve as external bus pins. When the device is used in external bus
mode, therefore, these ports are restricted on use.
Ports 2 and 3 can be used as ports even in external bus mode depending on the setting of the corresponding
function select bit.

6. PWC Timer
The PWC (pulse width count) timer is a 16-bit multifunction up-counter with reload timer functions and inputsignal pulse-width count functions as well.
The PWC timer consists of a 16-bit counter, a input pulse divider, a divide ratio control register, a count input
pin, a pulse output pin, and a 16-bit control register.
(1) Features of the PWC timer
The PWC timer has the following features:
• Timer functions
Generates an interrupt request at set time intervals.
Outputs pulse signals synchronized with the timer cycle.
Selects the counter clock from among three internal clocks.
• Pulse-width count functions
Counts the time between external pulse input events.
Selects the counter clock from among 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.

7. 16-bit I/O timer
The 16-bit I/O timer module consists of one 16-bit free run timer, four input capture circuits, and two output
comparators. 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 channel)
The 16-bit free run timer consists of a 16-bit up-counter, a control register, and a prescaler. The value output
from this timer/counter is used as the base time for the input capture and output compare modules.
• Counter operation clock (Selectable from among the following four)
Four internal clock cycles: φ/4, φ/16, φ/64, φ/256
φ: Machine clock
• Interrupts
An interrupt can be generated when the 16-bit free-run timer causes a counter overflow or by compare/match
operation with compare register 0. (The compare/match operation requires the mode setting).
• Counter value
An interrupt can be generated when the 16-bit free-run timer causes a counter overflow or when a match with
compare register 0 occurs (The compare/match function can be used by the appropriate mode setting).
• Initialization
The counter value can be initialized to “0000H” at a reset, soft clear operation, or a match with compare register 0.
(2) Output compare module (2 channels)
The output compare module consists of two 16-bit compare registers, compare output latches, and control
registers. When the 16-bit free-run timer value matches the compare register value, this module generates an
interrupt while inverting the output level.
• Two compare registers can operate independently.
Output pin and interrupt flag for each compare register
• A pair of compare registers can be used to control the output pin.
Two compare registers can be used to invert the output pin polarity.
• The initial value for each output pin can be set.
• An interrupt can be generated by compare/match operation.
(3) Input capture module (4 channels)
The input capture module consists of capture registers and control registers respectively associated with four
independent external input pins. This module can hold the 16-bit free run timer value in the capture register. In
addition, it can detect an arbitrary edge of the signal input from each external input pin to generate an interrupt.
• The external input signal edge to be detected can be selected.
One or both of the rising and falling edges can be selected.
• Four input capture channels can operate independently.
• An interrupt can be generated at a valid edge of the external input signal.
The extended intelligent I/O service can be activated by the interrupt by the input capture module.

10. DTP/External Interrupts
The DTP (Data Transfer Peripheral) is a peripheral block that interfaces external peripherals to the F2MC-16LX
CPU. The DTP receives DMA and interrupt processing requests from external peripherals and passes the
requests to the F2MC-16LX CPU to activate the intelligent I/O service or interrupt processing. Two request levels
(“H” and “L”) are provided for the intelligent I/O service. For external interrupt requests, generation of interrupts
on a rising or falling edge as well as on “H” and “L” levels can be selected, giving a total of four types.

11. Delayed Interrupt Generation Module
The delayed interrupt generation module is used to generate the task switching interrupt. Interrupt requests to
the F2MC-16LX CPU can be generated and cleared by software using this module.
(1) Register configuration
The DIRR register controls generation and clearing of delayed interrupt requests. Writing “1” to the register
generates a delayed interrupt request. Writing “0” to the register clears the delayed interrupt request. The register
is set to the interrupt cleared state by a reset. Either “0” or “1” can be written to the reserved bits. However,
considering possible future extensions, it is recommended that the set bit and clear bit instructions are used for
register access.

12. A/D Converter
The A/D converter converts analog input voltages to digital values. The A/D converter has the following features.
• Conversion time: Minimum of 34.7 µs per channel (for a 12 MHz machine clock)
• Uses RC-type successive approximation conversion with a sample and hold circuit.
• 8/10-bit resolution
• Eight program-selectable analog input channels
Single conversion mode: Selectively convert one channel.
Scan conversion mode: Continuously convert multiple channels. Maximum of 8 program 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.)
• An A/D conversion completion interrupt request.
An A/D conversion completion interrupt request to the CPU can be generated on the completion of A/D
conversion. This interrupt can activate EI2OS to transfer the result of A/D conversion to memory and is suitable
for continuous operation.
• Activation by software, external trigger (falling edge), or timer (rising edge) can be selected.

18. Address Match Detection Function
When an 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 match detection function is implemented by processing using
the INT9 interrupt 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.

20. One-Megabit Flash Memory
The 1Mbit flash memory is allocated in the FEH to FFH banks on the CPU memory map. Like masked ROM,
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 1Mbit flash memory
• 128K words x 8 bits or 64K words x 16 bits (16K + 8K x 2 + 32K + 64K) sector configuration
• Automatic program algorithm (Embedded Algorithm*: Same as the MBM29F400TA)
• Erasure suspend/resume function integrated
• Detection of programming/erasure completion using the data polling or toggle bit
• Detection of programming/erasure completion using CPU interrupts
• Compatible with JEDEC standard commands
• Capable of erasing data sector by sector (arbitrary combination of sectors)
• Minimum number of times of programming/erasure: 10,000

21. Low-Power Consumption Control Circuit
The operation modes of the MB90580C series are the PLL clock, PLL sleep, watch, main clock, main sleep,
stop, and hardware standby modes. The operation modes excluding the PLL clock mode are classified as lowpower consumption modes.
The low power consumption circuit has the following functions.
• Main clock mode/Main sleep mode
In either mode, the microcontroller operates only with the main clock (OSC oscillation clock), using the main
clock as the operating clock while suspending the PLL clock (VCO oscillation clock).
• PLL sleep mode/Main sleep mode
These modes stop only the operation clock of the CPU, leaving the other clocks active.
• Watch mode
The watch mode allows only the time-base timer to operate.
• Stop mode/Hardware standby mode
These modes stop oscillation while retaining data at the lowest power consumption. The CPU intermittent
operation function causes the clock supplied to the CPU to operate intermittently when the CPU accesses a
register, internal memory, internal resource, or external bus. This function saves power consumption by
decreasing the execution speed of the CPU while providing high-speed clock signals to the internal resources.
The PLL clock multiplication factor can be selected from among 1, 2, 3, and 4 using the CS1 and CS0 bits in
the clock selection register.
The WS1 and WS0 bits can be used to set the oscillation settling time for the main clock, which is taken to
wake up from the stop or hardware standby mode.

• Use within recommended operating conditions.
• Use at DC voltage (current)
• The +B signal should always be applied with a limiting resistance placed between the +B signal and the
microcontroller.
(Continued)
79
MB90580C Series
(Continued)
• The value of the limiting resistance should be set so that when the +B signal is applied the input current to
the microcontroller pins 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 throughthe 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 suplly 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 other than the A/D input pins (LCD drive pins, comparator inputpins,
etc.) cannot accept +B signal 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 or fewer per second, however, you can use the PLL clock.

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
Select the output impedance value for the external circuit of analog input according to the following conditions.
Output impedance values of the external circuit of 15.5 kΩ or lower are recommended.
When capacitors are connected to external pins, the capacitance of several thousand times the internal capacitor
value is recommended to minimized the effect of voltage distribution between the external capacitor and internal
capacitor.
When the output impedance of the external circuit is too high, the sampling period for analog voltages may not
be sufficient (sampling period = 4.00 µs @machine clock of 16 MHz)
