HT46RU26 General Description

The HT46RU26/HT46CU26 is an 8-bit high performance RISC architecture microcontrollers, designed especially for applications that interface directly to analog signals, such as those from sensors.

The device includes an integrated multi-channel Analog to Digital Converter in addition to four Pulse Width Modulator
outputs. The usual Holtek MCU features such as power down and wake-up functions, oscillator options, programmable frequency divider, etc. combine to ensure user applications require a minimum of external components.

With a fully integrated UART function and both SPI and I²C interfaces, a convenient means is provided for easy and efficient interfacing to external personal computers or other external hardware.

The benefits of these combined integrated functions, in addition to low power consumption, high performance, I/O flexibility and low-cost, provide these devices with the versatility to suit a wide range of application possibilities such as sensor signal processing, motor driving, industrial control, consumer products, subsystem controllers, etc.

The HT46CU26 is under development and will be available soon.

HT46RU66 General Description

The HT46RU66/HT46CU66 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 HT46CU66 mask version device, is fully pin and functionally compatible with its sister HT46RU66 OTP device.

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