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. |
