s DIFFERENCES AMONG PRODUCTS

1. Memory Size

Before evaluating using the OTPROM (one-time PROM) product (also used for evaluation), verify its differences

from the product that will actually be used: Take particular care on the following points:

• On the MB89663, register bank from 16 to 32 cannot be used.

• On the MB89P665, address BFF0H to BFF6H comprise the option setting area, option settings can be read by

reading these addresses.

• The stack area, etc., is used.

2. Current Consumption

• When operated at low speed, the product with an OTPROM or an EPROM will consume more current than

the product with a mask ROM.

• However, the current comsumption in sleep/stop modes is the same. (For more information, see sections

“s Electrical Characteristics” and “s Example Characteristics.”

3. Mask Options

Functions that can be selected as options and how to designate these options vary by the product.

Before using options check section “s Mask Options.”

Take particular care on the following points:

• On the MB89P665, a pull-up resistor must be selected in a group of four pins for P54 to P57.

• For all products, P50 to P57 must be set to without a pull-up resistor when an A/D converter is used.
