General Description

The HT46R64/HT46C64 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 HT46C64 is fully pin and

functionally compatible with the OTP version HT46R64

device.

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.

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

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

HT46C64 under development, available in 4Q, 2004.
