DESCRIPTION
The MB89480 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 timebase timer, watch prescaler, PWC timer, PWM timer, 8/16-bit timer/counter, 6-bit PPG, LCD controller/
driver, external interrupt 1 (edge), external interrupt 2 (level), 10-bit A/D converter, UART/SIO, buzzer, watchdog
timer reset.
The MB89480 series is designed suitable for LCD remote controller 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 is set at the upper limit of the RAM.
2. Current Consumption
• For the MB89PV480, the current consumed by the EPROM mounted in the piggy-back socket is needed to
be included.
• 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 is roughly the same in sleep and stop mode.
• For more information, see “s ELECTRICAL CHARACTERISTICS”.
3. Oscillation Stabilization Time after Power-on Reset
•
•
•
•
For MB89PV480, MB89P485L and MB89485L, there is no power-on stabilization time after power-on reset.
For MB89P485, there is power-on stabilization time after power-on reset.
For MB89485, the power-on stabilization time can be selected.
For more information, please refer to “s MASK OPTION”.
