General Description
The HT45FM03B is 8-bit, high performance, RISC ar-
chitecture microcontroller device which includes a host
of fully integrated special features specifically designed
for brushless DC motor applications.
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, power-down and wake-up
functions, although especially directed at brushless DC
motor applications, the enhanced versatility of this de-
vice also makes it applicable for use in a wide range of
A/D application possibilities such as sensor signal pro-
cessing, motor driving, industrial control, consumer
products, subsystem controllers, etc.
