General Description
The HT46R46/HT46C46 and HT46R47/HT46C47 are
8 - b it , hi gh per f orm a n c e , R IS C a r c h ite c tu r e
microcontroller devices specifically designed for A/D
applications that interface directly to analog signals,
such as those from sensors. The mask version
HT46C46, HT46C47 are fully pin and functionally com-
patible with the OTP version HT46R46, HT46R47 de-
vice.
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.
