PACKAGE AND CORRESPONDING PRODUCTS
DIFFERENCES AMONG PRODUCTS
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 MB90V378 does not have an internal ROM, however, operations equivalent to chips with an internal ROM
• In the MB90V378, images from FF4000
• In the MB90F378, images from FF4000
Assurance for the MB90V378 is given only for operation with a tool at power supply voltage of 2.7 V to 3.6 V,
an operating temperature of 0 °C to +25 °C, and an operating frequency of 1 MHz to 20 MHz.

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