DESCRIPTION
The MB89143A/144A 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 peripheral functions such as dual-clock
control system, five operating speed control stages, timers, a serial interface, an A/D converter, buzzer output,
high voltage driver, watch prescaler, and an external interrupt. The MB89143A/144A is applicable to a wide range
of applications from welfare products to industrial equipment.

Two types of timers
8/16-bit timer/counter (also usable as two 8-bit timers)
21-bit time-base timer
One 8-bit serial interface
Switchable transfer direction allows comunication with various equipment.
8-bit A/D converter: 8 channels
Successive approximation type
External interrupt: 2 channels
Two channels are independent and capable of wake-up from low-power consumption modes. (Rising edge/
falling edge/both edges selectability)
0.3 V to +7.0 V can be applied to INT1 (N-ch open-drain)
Low-power consumption modes
Subclock mode (The main clock stops, and the device operates at the subclock.)
Watch mode (Only the watch prescaler is operating.)
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.)
Watch prescaler
Buzzer output
Watchdog reset, reset output, and power-on reset functions

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 MB89143A/144A, the upper half of the register bank cannot be used.
The stack area, etc., is set at the upper limit of the RAM.
2.
Functions
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 A/D converter in the MB89143A/144A is an 8-bit resolution type. The MB89143A/144A contains neither
the 8-bit PWM timer nor the 12-bit MPG timer.
3.
Current Consumption
In the case of the MB89PV140, 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 section
"
s
Electrical Characteristics".)
4. 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 point:
A pull-up resistor option is not provided for the MB89PV140.
