DESCRIPTION
The MB89650AR 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, PWM timers, a serial interface, an A/D
converter, external interrupts, an LCD controller/driver, 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 MB89653AR, the upper half of the register bank cannot be used.
On the MB89P657A, the program area starts from address 8006
H
but on the MB89PV650A and MB89657AR
starts from 8000
H
.
(On the MB89P657A, addresses 8000
H
to 8005
H
comprise the option setting area, option settings can be read
by reading these addresses. On the MB89PV650A and MB89657A, addresses 8000
H
to 8005
H
could also be
used as a program ROM. However, do not use these addresses in order to maintain compatibility of the
MB89P657A.)
The stack area, etc., is set at the upper limit of the RAM.
2. Current Consumption
In the case of the MB89PV650A, 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 P70 to P75 on the MB89P657A. On this product, a pull-up resistor must
be selected in a group of four bits for P14 to P17, P40 to P43, and P44 to P47.
A pull-up resistor is not selectable for P30 to P37 and P40 to P47 if they are used as LCD pins.
Options are fixed on the MB89PV650A.
4. Differences between the MB89650A and MB89650AR Series
Electrical specifications/electrical characteristics
Electrical specifications of the MB89650AR series are the same with that of the MB89650A series.
Electrical characteristics of both series are much the same.
Oscillation circuit type
In the MB89650A series, the circuit type of using an external clock differs from that of using a crystal or ceramic
resonator as follows.
Circuit type of the MB89650AR series is a circuit type in using external clock even when crystal or ceramic
resonator is selected.
Memory access area and other specifications of both the MB89650A and MB89650AR series are the same.
