DESCRIPTION
The MB89120 series is a line of single-chip microcontrollers containing a compact instruction set and a great
variety of peripheral functions such as a timer, serial interface, and external interrupt. The MB89120A series is
an extended variant of the MB89120, with a remote control transmission function and wake-up interrupt channels.

DIFFERENCES AMONG PRODUCTS
1.
Memory Size
Before evaluating using the one-time ROM product, verify its difference from the product that will actually be
used. Take particular care on the following points :
The number of register banks available is different between the MB89121 and the MB89123A/125A/P135A/
PV130A.
The stack area, etc., is set at the upper limit of the RAM.
2.
Current Consumption
When operated at low speed, a product with an OTPROM (EPROM) will consume more current than a product
with a mask ROM. However, the same is current consumption in the sleep/stop mode is the same. (For more
information, see "
s
ELECTRICAL CHARACTERISTICS".)
In the case of the MB89PV130A, added is the current consumed by the EPROM which is connected to the
top socket.
3.
Mask Options
Functions that can be selected as options and how to designate these options vary with product.
Before using options, check "
s
MASK OPTIONS".
Take particular care on the following point :
Pull-up resistor can't be set for P40 to P43 on the MB89P135A.
Options are fixed on the MB89PV130A.
