MB95130MB Series

■ DIFFERENCES AMONG PRODUCTS AND NOTES ON SELECTING PRODUCTS

• Notes on using evaluation products

The Evaluation product has not only the functions of the MB95130MB series but also those of other products to

support software development for multiple series and models of the F2MC-8FX. The I/O addresses for peripheral

resources not used by the MB95130MB series are therefore access-barred. Read/write access to those 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 an odd-numbered-byte address in the prohibited areas (If such access is

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 software processing.

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

to these bits does not cause hardware malfunctions. No particular precautions are required to the flash memory

and mask ROM products, as they have the identical read/write operation to the evaluation products.

• Difference of memory spaces

If the amount of memory on the Evaluation product is different from that of the Flash memory 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 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 DIMENSION”.

• Operating voltage

The operating voltage is different among the Evaluation, Flash memory, and MASK ROM products.

For details of the operating voltage, refer to “

■ ELECTRICAL CHARACTERISTICS”.

• Difference MOD Pins

A pull-down resistor is provided for the MOD pin of the MASK ROM product.
