MB89144A

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. s FEATURES Minimum execution time: 0.50 µs/8.0-MHz oscillation Interrupt servicing time: 4.50 µs/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 (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 Exte...
