DESCRIPTION

■

The MB90570 series is a general-purpose 16-bit microcontroller developed and designed by Fujitsu for process
control applications in consumer products that require high-speed real time processing. It contains an I
interface that allows inter-equipment communication to be implemented readily. This product is well adapted to
car audio equipment, VTR systems, and other equipment and systems.

The instruction set of F
sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions, and
enhanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long word
data.

MC-16LX CPU core inherits AT architecture of F2MC*1 family with additional instruction

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 MB90V570/A does not have an internal ROM, however, operations equivalent to chips with an internal
ROM can be ev aluated b y using a dedicated development tool, enabling selection of ROM size b y settings of
the development tool.

• In the MB90V570/A, images from FF4000
mapped to bank FE and FF only. (This setting can be changed by configuring the development tool.)

• In the MB90F574/574/573/F574A/574C, images from FF4000H to FFFFFFH are mapped to bank 00, and
FF0000

• The products designated with /A or /C are different from those without /A or /C in that they are DTP/externally­interrupted types which return from standby mode at the ch.0 to ch.1 edge request.

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.
In turning on/turning off the analog power supply , mak e sure the analog po wer v oltage (AV

analog input voltages not exceed the digital voltage (V

CC).

CC, AVRH, D VCC)and

2. Treatment of unused pins

Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the
device. Therefor they must be tied to V
more than 2 k<Symbol>W.
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.

CC or Ground through resistors. In this case those resistors should be

3. Notes on Using External Clock

In using the external clock, drive X0 pin only and leave X1 pin unconnected.

• Using external clock

MB90570 series

X0

Open

X1

4. Unused Sub Clock Mode

If sub clock modes are not used, the oscillator should be connected to the X01A pin and X1A pin

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 V

16

CC and VSS pins via lowest impedance to power lines.

MB90570 Series

It is recommended to provide a bypass capacitor of around 0.1 µF between VCC and VSS pin near the device.

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 do 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, D/A converter power supply (AVCC, AVR H, AVRL ,
DV

CC,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 the voltage does not exceed AVRH or AVCC (tur ning on/off the analog and digital power supplies simulta­neously is acceptable).

8. Connection of Unused Pins of A/D Converter

Connect unused pins of A/D converter to AVCC = VCC, AVSS = AVRH = DVCC = VSS.

9. N.C. Pins

The N.C. (internally connected) pins 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
or more µs (0.2 V to 2.7 V).

11. 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. (MB90573, MB90574, MB90V570, MB90V570A)

17

MB90570 Series

The series without built-in step-down circuit have no oscillation setting time of step-down circuit, so outputs
should not become indeterminate. (MB90F574,MB90F574A,MB90574C)

12. Initialization

In the device, there are internal registers which are initialized only by a po wer-on reset. Turn on the power again
to initialize these registers.

13. 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 de vice via the external reset pin to return to the normal
state.

14. 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.

15. Precautions for Use of REALOS

Extended intelligent I/O service (EI2OS) cannot be used, when REALOS is used.

enabling reference of the table on the ROM without stating “far”.

Descriptions for initial value

0 : The initial value of this bit is “0”.
1 : The initial value of this bit is “1”.
X : The initial value of this bit is undefined.
– : This bit is unused. The initial value is undefined.

*1: This area is the only external access area having an address of 0000FF

area is handled as that to external I/O area.
*2: For details of the RAM area, see “■ MEMORY MAP”.
*3: The reserved area is disabled because it is used in the system.

Notes: • 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.

• The addresses following 0000FF

• Boundary ####H between the RAM area and the reserved area varies with the product model.

H are reserved. No external bus access signal is generated.
