HT46RU67/HT46CU67 -- A/D Type 8-Bit MCU with LCD

General Description

The HT46RU67/HT46CU67 are 8-bit, high performance, RISC architecture microcontroller devices specifically designed for A/D product applications that interface directly to analog signals and which require an LCD Interface. The HT46CU67, mask version device, is fully pin and functionally compatible with its sister HT46RU67 OTP device.

The advantages of low power consumption, I/O flexibility, timer functions, oscillator options, multi-channel A/D Converter, Pulse Width Modulation function, UART, serial I/O interface, 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 applications 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.
