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:
On the MB89PV870, the program area starts from address 8006
H
but on the MB89P875 and MB89875 starts
from 8000
H
.
(On the MB89P875, addresses BFF0
H
to BFF6
H
comprise the option setting area, option settings can be read
by reading these addresses. On the MB89PV870 and MB89875, addresses 8000
H
to 8006
H
could also be
used as a program ROM. However, do not use these addresses in order to maintain compatibility of the
MB89P875.)
2. Current Consumption
In the case of the MB89PV870, 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
“
I
Electrical Characteristics” and “
I
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 “
I
Mask Options.”
Take particular care on the following points:
A pull-up resistor cannot be selectable for P30 to P37 if they are used as the analog input pin for an A/D
converter.
A pull-up resistor cannot be selectable for P10 to P17, and P34 to P37 if an OP amp is used.
A pull-up resistor is not selectable for P40 to P47 and P23, P24 if they are used as LCD pins.
Options are fixed on the MB89PV870.
