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.

The advantages of low power consumption, I/O flexibil-

ity, timer functions, oscillator options, multi-channel A/D

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 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.
