MB95120MB Series

■ DIFFERENCES AMONG PRODUCTS AND NOTES ON SELECTING PRODUCTS

• Notes on Using Evaluation Products

The Evaluation product has not only the functions of the MB95120MB 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 MB95120MB 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.

Particularly, do not use word access to odd numbered byte address in the prohibited areas (If these access are

used, the address may be read or written unexpectedly).

Also, as the read values of prohibited addresses on the evaluation product are different to the values on the

Flash memory and MASK ROM products, do not use these values in the program.

The Evaluation 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 Evaluation, Flash memory product, and MASK ROM

product are designed to behave completely the same way in terms of hardware and software.

• Difference of Memory Spaces

If the amount of memory on the Evaluation product is different from that of the Flash memory product or MASK

ROM product, carefully check the difference in the amount of memory from the model to be actually used when

developing software.

For details of memory space, refer to “

■ CPU CORE”.

• Current Consumption

• The current consumption of Flash memory 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, refer to “

■ PACKAGES AND CORRESPONDING PRODUCTS” and

“

■ PACKAGE DIMENSIONS”.

• Operating voltage

The operating voltage are different between the Evaluation, Flash memory products, and MASK ROM product.

For details of operating voltage, refer to “

■ ELECTRICAL CHARACTERISTICS”.
