1.1 Overview
1.1.1
Overview
The MN103S is a 32-bit microcontroller combining ease of use intended for programs development in the C lan-
guage with a simple, high-performance architecture made possible through pursuit of cost performance.
Built around a compact 32-bit CPU with a basic instruction word length of 1 byte, this LSI includes internal mem-
ory for instructions and data, a clock generator, bus controller, interrupt controller, watchdog timer, standard
peripheral circuitry such as timers and serial interfaces, PWM circuit best suited to controlling 3-phase motors
and A/D converters for motor position control. The MN103S Series’ high-speed CPU coupled with abundance of
peripheral features provides an easy means of developing low-cost, high-performance and multifunctional system
on chip for motor and power control applications requiring fast response - a feature previously unavailable with
conventional microcontrollers.
