s DIFFERENCES AMONG PRODUCTS

1. Memory Size

Before evaluating using the OTPROM (one-time PROM) products (also used for evaluation), verify its differences

from the product that will actually be used.

Take particular care on the following point:

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

2. Current Consumption

When operated at low speed, the product with an OTPROM 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.

3. Mask Options

In the MB89P857/W857, no option can be set.

Before using options check section “s Mask Options.”

Take particular care on the following point:

• A pull-up resistor can be set for P00 to P07, P10 to P17 and P20 to P27 only at single-chip mode.
