s DIFFERENCES AMONG PRODUCTS

1. Memory Size

Before evaluating using the piggyback product, verify its differences from the product that will actually be used.

Take particular care on the following points:

• The stack area, etc., is set at the upper limit of the RAM.

• The external area is used.

2. Current Consumption

• In the case of the MB89PV920, add the current consumed by the EPROM which is connected to the top socket.

• When operated at low speed, the product with an OTPROM (one-time PROM) or an EPROM will consume

more current than the product with a mask ROM.

However, the current consumption in sleep/stop modes is the same. (For more information, see section

“s Electrical 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.”
