■ DIFFERENCES AMONG PRODUCTS AND NOTES ON SELECTING PRODUCTS

• Notes on Using EVA Products

The EVA product has not only the functions of the MB95110A series but also those of other products to support

software development for multiple series and products of F2MC-8FX family. The I/O addresses for peripheral

resources not used by the MB95110A series are therefore access-barred. Read/write access to these access-

barred addresses may cause peripheral resources supposed to be unused to operate, resulting in unexpected

malfunctions of hardware or software.

Take particular care not to use word, long word, or similar access to read or write odd numbered bytes in the

prohibited areas.

Note that the values read from barred addresses are different between the EVA product and the FLASH or MASK

product. Therefore, the data must not be used for software processing.

The EVA product does not support the functions of some bits in single-byte registers. Read/write access to these

bits does not cause hardware malfunctions. Since the EVA, FLASH, and MASK products are designed to behave

completely the same way in terms of hardware and software, you do not have to pay special attention to specific

products.

• Difference of Memory Spaces

If the amount of memory on the EVA product is different from that of the FLASH or MASK product, carefully

check the difference in the amount of memory from the product to be actually used when developing software.

• Current Consumption

• The current consumption of FLASH product is typically greater than for MASK product.

• For details of current consumption, refer to “■ ELECTRICAL CHARACTERISTICS”.

• Package

For details of information on each package, see “■ PACKAGE DIMENSIONS”.

• Operating voltage

The operating voltage are different among the EVA, FLASH and MASK products.

For details of operating voltage, refer to “■ ELECTRICAL CHARACTERISTICS”

• Difference between RST and MOD pins

The RST and MOD pins are hysteresis inputs on the MASK product. A pull-down resistor is provided for the

MOD pin of the MASK product.
