HT46RU66/HT46CU66 -- A/D Type 8-Bit MCU with LCD
General Description
The HT46RU66/HT46CU66 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 an LCD Interface. The HT46CU66 mask version device, is fully pin and functionally compatible with its sister HT46RU66 OTP device.
The advantages of low power c***umption, I/O flexibility, timer functi***, oscillator opti***, multi-channel A/D Converter, Pulse Width Modulation function, Power Down 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 the industrial and home appliance application areas.
