General Description
The HT46R652 is an 8-bit, high performance, RISC ar-
chitecture microcontroller devices specifically designed
for A/D product applications that interface directly to an-
alog signals and which require an LCD Interface.
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 ap-
plications requiring analog signal processing and LCD
interfacing, such as electronic metering, environmental
monitoring, handheld measurement tools, motor driv-
ing, etc. for both the industrial and home appliance ap-
plication areas.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, multi-channel A/D
Converter, Pulse Width Modulation function,
