***HT46R63***/Holtek合泰HT46R63***

The HT46R63/HT46C63 are 8-bit, high performance, RISC architecture microcontroller devices specifically designed for A/D product applicati*** that interface directly to analog signals and which require LCD Interface. The mask version HT46C63 is fully pin and functionally compatible with the OTP version HT46R63 device.

The advantages of low power c***umption, I/O flexibility, timer functi***, oscillator opti***, multi-channel A/D Converter, Pulse Width Modulation function, HALT and wake-up functi***, in addition to a flexible and configurable LCD interface enhance the versatility of these devices to control a wide range of applicati*** requiring 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.
