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:

• On the MB89183L, MB89185L and MB89P185, addresses 0180H and later of the register bank cannot be used.

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

2. Current Consumption

• In the case of the MB89PV180, 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 the sleep/stop modes is the same. (For more information, see

sELECTRICAL 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 sMASK OPTIONS.

Take particular care on the following points:

• A pull-up resistor cannot be set for P20 to P27, P40 to P47 and P50 to P57 on the MB89P185.

• A pull-up resistor is not selectable for P10 to P17, P40 to P47 and P50 to P57 if they are used as LCD pins.

• Options are fixed on the MB89PV180.
