General Description
The HT46R62/HT46C62 are 8-bit, high performance,
RISC architecture microcontroller devices specifically
designed for A/D product applications that interface di-
rectly to analog signals and which require LCD Inter-
face. The mask version HT46C62 is fully pin and
functionally compatible with the OTP version HT46R62
device.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, multi-channel A/D
Converter, Pulse Width Modulation function, HALT 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 industrial and home appliance application areas.
