General Description
The HT45RM03 is 8-bit, high performance, RISC archi-
tecture microcontroller devices specifically designed for
A/D applications that interface directly to analog signals,
such as those from sensors.
The advantages of low power consumption, I/O flexibil-
ity, programmable frequency divider, timer functions,
oscillator options, multi-channel A/D Converter, Pulse
Width Modulation function, HALT and wake-up func-
tions, enhance the versatility of these devices to suit a
wide range of A/D application possibilities such as sen-
sor signal processing, motor driving, industrial control,
consumer products, subsystem controllers, etc.
