s DIFFERENCES AMONG PRODUCTS

1. Memory Size

Before evaluating using the one-time ROM product, verify its difference from the product that will actually be

used. Take particular care on the following points :

• The number of register banks available is different between the MB89121 and the MB89123A/125A/P135A/

PV130A.

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

2. Current Consumption

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

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

information, see “s ELECTRICAL CHARACTERISTICS”.)

• In the case of the MB89PV130A, added is the current consumed by the EPROM which is connected to the

top socket.

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 point :

• Pull-up resistor can’t be set for P40 to P43 on the MB89P135A.

• Options are fixed on the MB89PV130A.
