General Description
The HT46RU66/HT46CU66 are 8-bit, high perfor-
mance, RISC architecture microcontroller devices spe-
cifically designed for A/D product applications that
interface directly to analog signals and which require an
LCD Interface. The HT46CU66 mask version device, is
fully pin and functionally compatible with its sister
HT46RU66 OTP device.
Converter, Pulse Width Modulation function, Power
Down and Wake-up functions, in addition to a flexible
and configurable LCD interface enhance the versatility of
these devices to control a wide range of applications re-
quiring analog signal processing and LCD interfacing,
such as electronic metering, environmental monitoring,
handheld measurement tools, motor driving, etc. for both
the industrial and home appliance application areas.
The advantages of low power consumption, I/O flexibility,
timer functions, oscillator options, multi-channel A/D
