■ 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 MB90V820 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 MB90V820, images from FF8000H to FFFFFFH are mapped to bank 00, and FE0000H to FF7FFFH are

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

• In the MB90822/F822A, images from FF8000H to FFFFFFH are mapped to bank 00, and FF0000H to FF7FFFH

are mapped to bank FF only. In the MB90823/F823A, images from FF8000H to FFFFFFH are mapped to bank

00, and FE0000H to FF7FFFH are mapped to bank FE and bank FF only.
