F2MC-8L MB89870 Series
MB89875/P875/PV870
s DESCRIPTION
The MB89870 series is a line of single-chip microcontrollers. In addition to a compact instruction set, the
microcontrollers contain a variety of peripheral functions such as dual-clock control system, five operating speed
control stages, timers, a PWM timer, a serial interface, an A/D converter, an external interrupt, an LCD controller/
driver, and a watch prescaler.
