s DIFFERENCES AMONG PRODUCTS

1. Memory Size

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

Take particular care on the following points:

• On the MB89191/191A, addresses 0140H to 0180H cannot be used for register banks.

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

2. Current Consumption

• In the case of MB89PV190/PV190A, added is the current consumed by the EPROM which is connected to

the top socket.

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

products with a mask ROM.

However, the same is current consumption in the sleep/stop mode. (For more information, see “s Electrical

Characteristics.”)

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:

• Pull-up resistor optional cannot be set for P00 to P03, and P40 to P45 on the MB89191A/193A/195A/P195A.

• The power-on reset option is fixed as “enabled” for MB89P195/P195A.

• Options are fixed on the MB89PV190/PV190A.

4. MB89191AH/MB89193AH

MB89191AH/193AH are “L” level heavy output current drive type of P30 to P32 and P40 to P43 of MB89191A/

193A.Characteristics other than “L” level output of P30 to P32 and P40 to P43 are the same as MB89191A/193A.
