MB89610R Series
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 MB89613R, the upper half of the register bank cannot be used.
• The stack area, etc., is set at the upper limit of the RAM.
• External area is used.
2. Current Consumption
• In the case of the MB89PV620, 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 a product with a mask ROM.
• However, the current consumption in sleep/stop modes is the same. (For more information, see sections
“s Electrical Characteristics” and “s Example 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 section “s Mask Options.”
Take particular care on the following points:
• Pull-up resistor cannot be set for P40 to P47 on the MB89P625 and MB89W625.
• Options are fixed on the MB89PV620.
4. Differences between the MB89610 and MB89610R Series
• Memory access area
Memory access area of both the MB89615 and MB89615R is the same.
The access area of the MB89613 is different from that of the MB89613R when using in external bus mode.
