■ 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 MB90V820B 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 MB90V820B, 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 MB90822B/F822B/F828B, images from FF8000H to FFFFFFH are mapped to bank 00, and FF0000H to

FF7FFFH are mapped to bank FF only. In the MB90823B/F823B/F828B, images from FF8000H to FFFFFFH

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

Clock Supervisor Function

The clock supervisor is built-in in MB90F828B only. Note that the evaluation products and products actually used

are different when evaluating evaluation products. Please contact the sales representatives for more information

on evaluation of this function.

Modify ROM data

The registers include this function between 001FF0H and 001FF5H which overlap the RAM area of MB90F828B.

Do not access to the RAM when using this function in MB90F282B.
