General Description
The HT46R47-H is an 8-bit high performance, RISC ar-
chitecture microcontroller devices specifically designed
for A/D applications that interface directly to analog sig-
nals, 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.
The higher operating voltage range and higher operat-
ing temperature range of
-40°C
to +125°C for the
HT46R47-H make this series suitable for automotive ap-
plications as well.
