MB89657A集成电路（IC）的微控制器规格书PDF中文资料

■ DESCRIPTION

The MB89650AR series 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 a variety of peripheral functions such as dual-clock control system, five operating speed control stages, timers, PWM timers, a serial interface, an A/D converter, external interrupts, an LCD controller/driver, and a watch prescaler.
