MB89144A (MB89143A / MB89144A) 8-bit Proprietary Microcontroller

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.
