General Description
The HT46RU22 are 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, UART function, I²C inter-
face, HALT and wake-up functions, enhance the versa-
tility of these devices to suit a wide range of A/D
application possibilities such as sensor signal process-
ing, motor driving, industrial control, consumer prod-
ucts, subsystem controllers, etc.
