DESCRIPTION
The MB89640 series has been developed as a general-purpose version of the F
2
MC*-8L family consisting of
proprietary 8-bit, single-chip microcontrollers.
In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as
dual-clock control system, five operating speed control stages, timers, a PWM timer, serial interface, an A/D
converter, a D/A converter, an external interrupt, and a watch prescaler.

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 MB89643 register banks 16 to 32 cannot be used.
On the MB89P647, the program area starts from address 8007
H
but on the MB89PV640 and MB89647 starts
from 8000
H
.
(On the MB89P647, addresses 8000
H
to 8006
H
comprise the option setting area, option settings can be read
by reading these addresses. On the MB89PV640 and MB89647, addresses 8000
H
to 8006
H
could also be
used as a program ROM. However, do not use these addresses in order to maintain compatibility of the
MB89P647.)
The stack area, etc., is set at the upper limit of the RAM.
The external areas are used.
2. Current Consumption
In the case of the MB89PV640, 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 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:
A pull-up resistor cannot be set for P40 to P47 and P50 to P57 on the MB89P647.
For all products, P60 to P67 are available for no pull-up resistor when an A/D converter is used.
For all products, P50 to P57 are available for no pull-up resistor when a D/A converter is used.
Options are fixed on the MB89PV640.
