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.
