DIFFERENCES AMONG PRODUCTS
Memory Size
In evaluation with an evaluation product, note the difference between the evaluation product and the product
actually used. The following items must be taken into consideration.
The MB90V550A does not have an internal ROM. However, operations equivalent to those performed by a
chip with an internal ROM can be evaluated by using a dedicated development tool, enabling selection of ROM
size by setting the development tool.
In the MB90V550A, images from FF4000
H
to FFFFFF
H
are mapped to bank 00, and FE0000
H
to FF3FFF
H
are mapped to bank FE and FF only. (This setting can be changed by configuring the development tool.)
In the MB90F553A/553A/553B/552A/552B, images from FF4000
H
to FFFFFF
H
are mapped to bank 00, and
FF0000
H
to FF3FFF
H
to bank FF only.
