s DIFFERENCES AMONG PRODUCTS

1. Memory Size

In evaluation with an evaluation product, note the difference between the evaluation chip and the chip actually

used. The following items must be taken into consideration.

• The MB90V670 does not have an internal ROM, however, operations equivalent to chips with an internal ROM

can be evaluated by using a dedicated development tool, enabling selection of ROM size by settings of the

development tool.

• In the MB90V670, images from FF4400H to FFFFFFH are mapped to bank 00, and FE0000H to FF3FFFH to

mapped to bank FEH and FFH only. (This setting can be changed by configuring the development tool.)

• In the MB90678/MB90P678, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to

FF3FFFH to bank FF only.

2. Mask Options

Functions selected by optional settings and methods for setting the options are dependent on the product types.

Refer to “s Mask Options” for detailed information.

Note that mask option is fixed in MB90V670 series.
