s OUTLINE
The MB89660R series has been developed as a general-purpose version of the F2MC*-8L family consisting of
proprietary 8-bit single-chip microcontrollers.
In addition to a compact instruction set, the microcontrollers contain a great variety of peripheral functions such
as timers, a UART, a serial interface, an 8-bit A/D converter, an input capture, an output compare, and an external
interrupt.The MB89660R series is applicable to a wide range of applications from consumer products to industrial
equipment.

s DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the OTPROM (one-time PROM) product (also used for evaluation), verify its differences
from the product that will actually be used: Take particular care on the following points:
• On the MB89663R, register bank from 16 to 32 cannot be used.
• On the MB89P665, address BFF0H to BFF6H comprise the option setting area, option settings can be read by
reading these addresses.
• The stack area, etc., is used.
2. Current Consumption
• When operated at low speed, the product with an OTPROM or an EPROM will consume more current than
the product with a mask ROM.
• However, the same is the current comsumption in sleep/stop modes. (For more information, see sections “s
Electrical Characteristics” and “s Example Characteristics.”

3. Mask Options
Functions that can be selected as options and how to designate these options vary with product.
Before using options, check section “s Mask Options.”
Take particular care on the following points:
DataSheet4U.com
• On the MB89P665, a pull-up resistor must be selected in a group of four pins for P54 to P57.
• For all products, P50 to P57 must be set for no pull-up resistor optional when an A/D converter is used.

4. Differences between the MB89660 and MB89660R Series
• Memory access area
Memory access area of both the MB89660R and MB89660 series is the same.
• Other Specifications
For MB89660R series, input level at P00 to P07 and P10 to P17 is fixed when the hardware is standing-by.
And for MB89660 series, input level at P00 to P07 and P10 to P17 is not fixed. Therefore, when the medium
voltage is input there such as input open, the standby current will increase.
• Electrical specifications/electrical characteristics
There are differences at pull down resistances of MOD0 and MOD1 between MB89660R series and MB89660
series. For more information, see “3. DC characteristics” in section “s Electrical Characteristics”.
Electrical specification of the other items of MB89660R series and MB89660 series are equivalent.
However, it is possible that the valid characteristic will be modified. See the corresponding characteristic
respectively for detail.

s HANDLING DEVICES
1. Preventing Latchup
Latchup may occur on CMOS ICs if voltage higher than VCC or lower than VSS is applied to input and output pins
other than medium- and high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum
Ratings” in section “ s Electrical Characteristics” is applied between VCC and VSS.
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.
Also take care to prevent the analog power supply (AVCC and AVR) and analog input from exceeding the digital
power supply (VCC) when the analog system power supply is turned on and off.
2. Treatment of Unused Input Pins
Leaving unused input pins open could cause malfunctions. They should be connected to a pull-up or pull-down
resistor.
3. Treatment of Power Supply Pins on Microcontrollers with A/D Converters
Connect to be AVCC = VCC and AVSS = AVR = VSS if the A/D converters are not in use.

4. Power Supply Voltage Fluctuations
Although operation is assured within the rated range of VCC power supply voltage, a rapid fluctuation of the
voltage could cause malfunctions, even if it oDcactuarSshweitehti4nUt.hceomrated range. Stabilizing voltage supplied to the IC
is therefore important. As stabilization guidelines, it is recommended to control power so that VCC ripple
fluctuations (P-P value) will be less than 10% of the standard VCC value at the commercial frequency(50 to 60
Hz) and the transient fluctuation rate will be less than 0.1 V/ms at the time of a momentary fluctuation such as
when power is switched.

5. Precautions when Using an External Clock
When an external clock is used, oscillation stabilization time is required even for power-on reset (optional) and
wake-up from stop mode.
