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.
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
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.

SEG0~SEG47 are LCD driver outputs for LCD panel segments.
SEG10 is pin-shared with the SPI bus data output line, SDO.
SEG11 is pin-shared with the SPI bus data input line, SDI and the I2C Bus
data line SDA.
SEG12 is pin-shared with the SPI bus clock line, SCK and the I2C Bus
clock line SCL.
SEG13 is pin-shared with the SPI bus select line, SCS.
SEG14 is pin-shared with the Peripheral Clock line, PCLK.
SEG15 is pin-shared with the Peripheral Interrupt line, PINT.
The SEG0~SEG23 lines can be can be chosen to be either segment driv-
