General Description  
These TinyPowerTM A/D Type with LCD 8-bit high perfor-  
mance RISC architecture microcontrollers are specifi-  
cally, designed for applications that interface directly to  
analog signals and which require an LCD or LED inter-  
face. The devices include an integrated multi-channel An-  
alog to Digital Converter, Pulse Width Modulation outputs  
and an LCD/LED driver.  
a 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  
devices 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 their fully integrated SPI and I2C functions, design-  
ers are provided with a means of easy communication  
with external peripheral hardware. The benefits of inte-  
grated 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
