DESCRIPTION

The MB89143A/144A has been developed as a general-purpose version of the F²MC-8L(F²MC stands for FUJITSU Flexible Microcontroller) 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.

FEATURES


Minimum execution time: 0.50µs/8.0 MHz oscillation

Interrupt servicing time: 4.50µs/8.0 MHz oscillation

F²MC-8L family CPU core

Multiplication and division instructions

Instruction set optimized for controllers 16-bit arithmetic operations

Test and branch instructions

Bit manipulation instructions, etc.

Dual-clock control system

High-voltage ports: 24 channel

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
