General Description
The HT56R64 is a TinyPower^TM 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.
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
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.
