DESCRIPTION
The MB89910 series has been developed as a general-purpose version of the F
2
MC*-8L family consisting of
proprietary 8-bit, single-chip microcontrollers.
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 serial interface, an A/D converter, a
buzzer output, a low-voltage detection reset, high-voltage driver, a watch prescaler, and external interrupts.
The MB89910 series is applicable to a wide range of applications from consumer products to industrial
equipments.

DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the piggyback product, verify its differences from the product that will actually be used.
Take particular care on the following points:
· The stack area, etc., is set at the upper limit of the RAM.
2. Current Consumption
· In the case of the MB89PV910, add the current consumed by the EPROM which is connected to the top socket.
· 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
"
s
Electrical Characteristics" and "
s
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 "
s
Mask Options."
Take particular care on the following points:
· A pull-down resistor for P10 to P17, P20 to P27, and for P50 to P51 cannot be set for the MB89P915 and
MB89PV910. The MB89915 and MB89913 allow a pull-down resistor to be set for individual pins. Such pins
on the MB89P915 and MB89PV910 are fixed to have no pull-down resistor.
· The low-voltage detection reset cannot be used on the MB89PV910. The voltage to be detected by the low-
voltage detection reset is set by using a register for the MB89P915 and by using a mask option for the MB89915
and MB89913. If the detection voltage has been set to a lower value than the operating voltage, however, use
the gear function to operate the device with the faster clock at a lower speed, or operate the device with the
slower clock. Note that the results of operation are unpredictable if the device is attempted to operate at a
lower voltage than the operating voltage with the faster clock put in top gear.
