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 MB89623R, the upper half of the register bank cannot be used.
On the MB89P627, the program area starts from address 8007
H
but on the MB89PV620 and MB89627R starts
from 8000
H
.
(On the MB89P627, addresses 8000
H
to 8006
H
comprise the option setting area, option settings can be read
by reading these addresses. On the MB89PV620 and MB89627R, 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
MB89P627.)
The stack area, etc., is set at the upper limit of the RAM.
The external area is used.
2. Current Consumption
In the case of the MB89PV620, 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 section
“
I
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 “
I
Mask Options.”
Take particular care on the following points:
A pull-up resistor cannot be set for P40 to P47 on the MB89P625, MB89W625, MB89P627, and MB89W627.
A pull-up resistor is not selectable for P50 to P57 when the A/D converter is used.
Options are fixed on the MB89PV620.
