s DIFFERENCES AMONG MODELS

1. Memory Size

Before evaluating using the piggyback model, verify its difference from the model that will actually be used.

2. Current Consumption

• In the case of the MB89PV890, added is the current consumed by the EPROM which is connected to the top

socket.

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

product with a mask ROM. However, the same is current consumption in sleep/stop mode.

3. Mask Options

Functions that can be selected as options and how to designate these options vary with product. Before using

options, check “s Mask Options”. Take particular care on the following points:

• Options are fixed on the MB89PV890.

• Pull-up resistor options on the MB89P899 are in 2-bit units for P00 to P07, P10 to P17, P60 to P67, P90 to

P97, and PA0 to PA7. Options are in 1-bit units for P40 to P44, P70 to P77, P80 to P87.
