HT46R62/HT46C62 -- A/D with LCD Type 8-Bit MCU

General Description

The HT46R62/HT46C62 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 LCD Interface. The mask version HT46C62 is fully pin and functionally compatible with the OTP version HT46R62 device.

The advantages of low power consumption, I/O flexibility, 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 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.
