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 MB89P637/W637, the program area starts from address 8007
H
but on the MB89PV630 and MB89637R
starts from 8000
H
.
On the MB89P637/W637, addresses 8000
H
to 8006
H
comprise the option setting area, option settings can be
read by reading these addresses. On the MB89PV630/MB89637R, 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
MB89P637/W637.
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 MB89PV630, add the current consumed by the EPROM which 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 set for P50 to P53 on the MB89P637 and MB89W637.
Options are fixed on the MB89PV630, MB89T635R, and MB89T637R.
4. Differences between the MB89630 and MB89630R Series
Memory access area
There are no difference between the access area of MB89635/MB89635R, and that of MB89637/MB89637R.
The access area of MB89636 is different from that of the MB89636R when using in external bus mode.
