Overview
FUJITSU SEMICONDUCTOR DATA SHEET DS07-12528-2E 8-bit Proprietary Microcontroller CMOS F2MC-8L MB89143A/144A Series MB89143A/144A s DESCRIPTION The MB89143A/144A has been developed as a general-purpose version of the F2MC-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.
* F2MC stands for FUJITSU Flexible Microcontroller.

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 (Continued) s PACKAGE 64-pin Plastic SH-DIP (DIP-64P-M01) MB89143A/144A (Continued) • 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 ...
