The MB89660 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 timers, a UART, a serial interface, an 8-bit A/D converter, an input capture, an output compare, and an external interrupt. The MB89660 series is applicable to a wide range of applications from welfare products to industrial equipment.
