General Description  
The HT56R64 is a TinyPowerTM A/D Type with LCD 8-bit  
high performance RISC architecture microcontroller, de-  
signed especially for applications that interface directly to  
analog signals and which require an LCD interface. The  
device includes an integrated multi-channel Analog to Dig-  
ital Converter, four Pulse Width Modulation outputs and an  
LCD driver.  
wide range of products in the home appliance and in-  
dustrial application areas. Some of these products  
could include electronic metering, environmental moni-  
toring, handheld instruments, electronically controlled  
tools, motor driving in addition to many others.  
The unique Holtek TinyPower technology also gives the  
device extremely low current consumption characteris-  
tics, an extremely important consideration in the present  
trend for low power battery powered applications. The  
usual Holtek MCU features such as power down and  
wake-up functions, oscillator options, programmable  
frequency divider, etc. combine to ensure user applica-  
tions require a minimum of external components.  
With its fully integrated SPI and I2C functions, designers  
are provided with a means of easy communication with  
external peripheral hardware. The benefits of integrated  
A/D, LCD, and PWM functions, in addition to low power  
consumption, high performance, I/O flexibility and  
low-cost, provides the device with the versatility for a
