3. Product Comparison

Memory Space

When testing with test product for evaluation, check the differences between the product and a product to be used actually. Pay

attention to the following points:

■ The MB90V495G has no built-in ROM. However, a special-purpose development tool allows the operations as those of one with

built-in ROM. ROM capacity depends on settings on a development tool.

■ On MB90V495G, an image from FF4000H to FFFFFFH is viewed on 00 bank and an image of FE0000H to FF3FFFH is viewed only

on FE bank and FF bank. (Modified on settings of a development tool.)

■ On MB90F387/F387S/387/387S, an image from FF4000H to FFFFFFH is viewed on 00 bank and an image of FE0000H to FF3FFFH

is viewed only on FF bank.
