DESCRIPTION
The MB89810A series is a line of single-chip microcontrollers based on the F
2
MC*-8L CPU core which can operate
at low voltage but at high speed. The microcontrollers contain peripheral function such as timer, serial interface,
a UART, and an external interrupt. The MB89810A series is applicable to a wide range of applications from welfare
products to industrial equipment, including portable devices.

(Continued)
• Two serial interface
8-bit synchronous serial (Switchable transfer direction allows communication with various equipment.)
UART (5-, 7-, or 8-bit transfer capable)
• External interrupt: 8 channels
Eight channels are independent and capable of wake-up from low-power consumption modes (with an edge
detection function).
• Low-power consumption modes
Stop mode (Oscillation stops to minimize the current consumption)
Sleep mode (The CPU stops to reduce the current consumption to approx. 1/3 of normal)

DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the OTPROM (one-time PROM) products, verify its differences from the product that
will actually be used.
2. Current Consumption
When operated at low speed, the product with an OTPROM will consume more current than the product with a
mask ROM.
However, the same is current consumption in sleep/stop modes (For more information, see “s ELECTRICAL
CHARACTERISTICS”) .
3. Mask Options
Functions that can be selected as options and how to designate these options vary with product.
Before using options, check “s MASK OPTIONS”.
Take particular care on the following point:
For MB89816A, pull-up resistor option can be set for P50 to P54.
