OUTLINE
The MB89990 series microcontrollers contain various resources such as timers, external interrupts, and remote-
control functions, as well as an F

· External interrupts
Edge detection (Edge selection enabled): 3 channels
Low-level interrupt (Wake-up function): 8 channels
· Internal remote-control transmission frequency generator
· Low-power consumption modes
Stop mode (Almost no current consumption occurs because oscillation stops.)
Sleep mode (The current consumption is about 1/3 of that during normal operation because the CPU stops.)

DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the piggyback model, verify its difference from the model that will actually be used.
Take particular care on the following points:
· On the MB89997, addresses 0140
H
to 0180
H
cannot be used for register banks.
· The stack area, etc., is set in the upper limit of the RAM.
2. Current Consumption
· In the case of MB89PV190, add the current consumed by the EPROM which is connected to the top socket.
· When operated at low speed, a model with an OTPROM (EPROM) will consume more current than a model
with a mask ROM.
However, current consumption in the sleep/stop mode in the same. (For more information, see "
s
Electrical
Characteristics.")
3. Mask Options
Functions that can be selected as options and how to designate these options vary by model.
Before using options check "
s
Mask Options."
Take particular care on the following points:
· The power-on reset option is fixed as "enabled" for MB89P195.
· Options are fixed on the MB89PV190.
