DESCRIPTION
The MB89470 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 microcontroller contains a variety of peripheral functions such as 21-
bit time-base timer, watch prescaler, PWC timer, PWM timer, 8/16-bit timer/counter, external interrupt 1 (edge) ,
external interrupt 2 (level) , 10-bit A/D converter, UART/SIO, buzzer, watchdog timer reset.
The MB89470 series is designed suitable for home appliance as well as in a wide range of applications for
consumer product.

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 point :
The stack area, etc., is set at the upper limit of the RAM.
2.
Current Consumption
For the MB89PV470, add the current consumed by the EPROM mounted in the piggy-back socket.
When operating at low speed, the current consumed by the one-time PROM product is greater than that for
the mask ROM product. However, the current consumption are roughly the same in sleep or stop mode.
For more information, see "
s
ELECTRICAL CHARACTERISTICS".
3.
Oscillation stabilization time after power-on reset
For MB89PV470, there is no power-on stabilization time after power-on reset.
For MB89P475, there is power-on stabilization time after power-on reset.
For MB89475, the power-on stabilization time can be select.
For more information, refer to "
s
