■ DIFFERENCES AMONG PRODUCTS AND NOTES ON SELECTING PRODUCTS
• Notes on Using EVA Products
The EVA product has not only the functions of the MB95100A corresponding products series but also those of
other products to support software development for multiple series and models of the F²MC-8FX family. The I/
O addresses for peripheral resources not used by the MB95100A 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 do 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 model to be actually used when developing software.
• Current Consumption
• The current consumption of FLASH product is typically greater than for MASK ROM 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.
