DESCRIPTION
The MB89980 series is a line of the general-purpose, single-chip microcontrollers. In addition to a compact
instruction set, the microcontrollers contain a variety of peripheral functions such as an LCD controller/driver,
an A/D converter, timers, remote control transmission output, buzzer output, PWM timers, and external interrupts.

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 MB89PV980, 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 the sleep/stop modes is the same. (For more information, see section
"
s
Electrical 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-up resistor is not selectable for P40 to P47 and P60 to P65 if they are used as LCD pins.
A pull-up resistor is not selectable for P50 to P53 if they are used as analog input.
4. Pull-up resistor
Pull-up resisitors of MB89P985 and MB89PV980 are selected by pull-up control registor (Port 0, 1, 5), but there
are no pull-up resistor for Port 2, 4 and 6 in MB89P985 and MB89PV980.
ALL pull-up resistor of MB89983 are selected by mask option (Port 0, 1, 2, 4, 5, 6)
5. Segment/Common port
The Segment/Port , Common/Port output in MB89P985 and MB89PV980 are selected by control register, LCR2.
The Segment/Port , Common/Port output in MB89983 are selected by mask option.
