■ 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 MB89P147, the program area starts from address 8007H but on the MB89PV140 starts from 8000H.
(On the MB89P147, addresses 8000H to 8006H comprise the option setting area, option settings can be read
by reading these addresses. On the MB89PV140, addresses 8000H to 8006H could also be used as a program
ROM. However, do not use these addresses in order to maintain compatibility of the MB89P147.)
The stack area, etc., is set at the upper limit of the RAM.
2. Current Consumption
In the case of the MB89PV140, 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 the product with a mask ROM.
However, the current consumption in sleep/stop modes is the same. (For more information, see section
“
■ ELECTRICAL 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 “
■ MASK OPTIONS”.
Take particular care on the following points:
Options are fixed on the MB89PV140.
On the MB89P147, MB89145, and MB89146, the pull-down resistor option can either be selected for all affected
pins, or for no pin; it is not possible to specify the pull-down resistor option for individual pins.
4. Subclock Oscillation Feedback Resistor
A built-in oscillation feedback resistor is provided for the subclock oscillator pin on the MB89PV140, but it is not
provided for the MB89145, MB89146, MB89P147. Therefor these products should be connected to an external
oscillation feedback resistor.
