s DIFFERENCES AMONG PRODUCTS

1. Memory Capacity

When this product is used in a piggy-back or other evaluation configuration, it is necessary to carefully confirm

the differences between the model being used and the product it is evaluating. Particular attention should be

given to the following (see " CPU core 1. Memory Space") .

• The program ROM area starts from address 4000H on the MB89P538, MB89F538L and MB89PV530 models.

• Note upper limits on RAM, such as stack areas, etc.

2. Current Consumption

• On the MB89PV530, the additional current consumed by the EPROM is added at the connecting socket on

the back side.

• When operating at low speed, the current consumption in the one-time PROM or EPROM models is greater

than on the mask ROM models. However, current consumption in sleep or stop modes is identical.

For details, refer to “ ELECTRICAL CHARACTERISTICS”.

3. Mask Options

The options available for use, and the method of specifying options, differ according to the model. Before use,

check the “ MASK OPTIONS” specification section.

4. Wild Register Functions
