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 MB89F538, MB89P538 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
The following table shows areas in which wild register functions can be used.
