DESCRIPTION
■
The MB89640 series has been developed as a general-purpose version of the F2MC*-8L family consisting of
proprietary 8-bit, single-chip microcontrollers.
DS07-12505-3E
In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as
dual-clock control system, five operating speed control stages, timers, a PWM timer, serial interface, an A/D
converter, a D/A converter, an external interrupt, and a watch prescaler.

DIFFERENCES AMONG PRODUCTS
■
1. Memory Size
Before e v aluating using the piggyback product, v erify its diff erences from the product that will actually be used.
Take particular care on the following points:
• On the MB89643 register banks 16 to 32 cannot be used.
• On the MB89P647, the program area starts from address 8007
from 8000H.
(On the MB89P647, addresses 8000
by reading these addresses. On the MB89PV640 and MB89647, addresses 8000
used as a program ROM. However, do not use these addresses in order to maintain compatibility of the
MB89P647.)
• The stack area, etc., is set at the upper limit of the RAM.
• The external areas are used.
H to 8006H comprise the option setting area, option settings can be read
H but on the MB89PV640 and MB89647 starts
H to 8006H could also be
2. Current Consumption
• In the case of the MB89PV640, add the current consumed by the EPROM which is connected to the top soc ket.
• When operated at low speed, the product with an OTPROM (one-time PROM) or an EPROM will consume
more current than the product with a mask ROM.
• However, the current consumption in sleep/stop modes is the same. (For more information, see sections
“■ Electrical Characteristics” and “■ Example Characteristics.”)
3. Mask Options
Functions that can be selected as options and how to designate these options vary by the product.
Before using options check section “■ Mask Options.”
Take particular care on the following points:
• A pull-up resistor cannot be set for P40 to P47 and P50 to P57 on the MB89P647.
• For all products, P60 to P67 are available for no pull-up resistor when an A/D converter is used.
• For all products, P50 to P57 are available for no pull-up resistor when a D/A converter is used.
• Options are fixed on the MB89PV640.

HANDLING DEVICES
■
1. Preventing Latchup
Latchup may occur on CMOS ICs if voltage higher than VCC or lo wer than VSS is applied to input and output pins
other than medium- to high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum
Ratings” in section “■ Electrical Characteristics” is applied between V
When latchup occurs, power supply current increases rapidly and might thermally damage elements. When
using, take great care not to exceed the absolute maximum ratings.
CC and VSS.
Also, tak e care to prevent the analog po wer supply (A V
power supply (VCC) when the analog system power supply is turned on and off.
CC and A VRH) and analog input from exceeding the digital
2. Treatment of Unused Input Pins
Leaving unused input pins open could cause malfunctions. The y should be connected to a pull-up or pull-do wn
resistor.
3. Treatment of Power Supply Pins on Microcontrollers with A/D and D/A Converters
Connect to be AVCC = DAVC = VCC and AVSS = AVRH = VSS even if the A/D and D/A converters are not in use.
4. Treatment of N.C. Pins
Be sure to leave (internally connected) N.C. pins open.
5. Power Supply Voltage Fluctuations
Although VCC power supply voltage is assured to oper ate within the rated range, a r apid fluctuation of the voltage
could cause malfunctions, ev en if it occurs within the rated range. Stabilizing voltage supplied to the IC is theref ore
important. As stabilization guidelines, it is recommended to control power so that V
value) will be less than 10% of the standard VCC value at the commercial frequency (50 to 60 Hz) and the tr ansient
fluctuation rate will be less than 0.1 V/ms at the time of a momentary fluctuation such as when power is switched.
CC ripple fluctuations (P-P
6. Precautions when Using an External Clock
Even when an external clock is used, oscillation stabilization time is required for power-on reset (optional) and
wake-up from stop mode.

The MB89P647 is an OTPROM version of the MB89640 series.
1. Features
• 32-Kbyte PROM on chip
• Options can be set using the EPROM programmer.
• Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer)
2. Memory Space
Memory space in each mode such as 32-Kbyte PROM, option area is diagrammed below.

• Precautions
(1) The program area of the MB89P647 is 7 bytes smaller than that of the MB89PV640 and MB89647 to provide
an option area. Note this point during program development.
(2) During normal operation, the option data is read when the option area is read from the CPU.
3. Programming to the EPROM
In EPROM mode, the MB89P647 functions equivalent to the MBM27C256A. This allows the PROM to be
programmed with a general-purpose EPROM programmer (the electronic signature mode cannot be used) by
using the dedicated socket adapter.
• Programming procedure
(1) Set the EPROM programmer to the MBM27C256A.
(2) Load program data into the EPROM programmer at 0007
while operating as internal ROM mode assign to 0007H to 7FFFH in EPROM mode).
Load option data into addresses 0000H to 0006H of the EPROM programmer. (For information about each
corresponding option, see “7. Setting OTPROM Options.”)
(3) Program with the EPROM programmer.

4. Recommended Screening Conditions
High-temperature aging is recommended as the pre-assembly screening procedure f or a product with a blanked
OTPROM microcomputer program.
Program, verify
Aging
+150°C, 48 Hrs.
Data verification
Assembly
5. Programming Yield
All bits cannot be programmed at Fujitsu shipping test to a blank ed O TPR OM microcomputer, due to its nature.
For this reason, a programming yield of 100% cannot be assured at all times.

Note: Depending on the EPR OM programmer , inserting a capacitor of about 0.1 µF between V
and VSS can stabilize programming operations.

7. Setting OTPROM Options
The programming procedure is the same as that for the PROM. Options can be set by programming values at
the addresses shown on the memory map. The relationship between bits and options is shown on the f ollowing

• Set each bit to 1 to erase.
• Do not write 0 to the vacant bit.
The read value of the vacant bit is 1, unless 0 is written to it.
