General Description
The HT46RU67/HT46CU67 are 8-bit, high perfor-
mance, RISC architecture microcontroller devices spe-
cifically 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 flexibil-
ity, timer functions, oscillator options, multi-channel A/D
Converter, Pulse Width Modulation function, UART, se-
rial 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 pro-
cessing and LCD interfacing, such as electronic meter-
ing, environmental monitoring, handheld measurement
tools, motor driving, etc. for both the industrial and home
appliance application areas.
