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.

Description
Bidirectional 8-bit input/output port. Each individual bit on this port can be
configured as a wake-up input using the PAWU register. Software instruc-
tions determine if the pin is a CMOS output or Schmitt trigger input. A
BZ/BZ
pull-high resistor can be connected to each pin using the PAPU register. Pins
I/O PA0, PA1 and PA3 are shared with BZ, BZ and PFD respectively, the function
PFD
of which is chosen via configuration option. Pins PA0~PA3 can also be setup
as open drain pins using the MISC register. The HT56R642 has no shared
pins with PA4. Pin PA4 is shared with TMR1 on the HT56R62 and with TMR2
on the HT56R65, HT56R654, HT56R656 and HT56R666.
Bidirectional 8-bit input/output port. Software instructions determine if the pin
is a CMOS output or Schmitt trigger input. A pull-high resistor can be con-
I/O
¾
nected to each pin using the PBPU register. PB is pin-shared with the A/D in-
put pins. The A/D inputs are selected via software instructions. Once selected
as an A/D input, the I/O function and pull-high resistor selections are disabled
automatically. HT56R62 has six PB pins, PB0/AN0~PB5/AN5 only.
Bidirectional 8-bit input/output port. Software instructions determine if the pin
is a CMOS output or Schmitt trigger input. A pull-high resistor can be con-
nected to each pin using the PDPU register. The PWM outputs,
I/O ¾ PWM0~PWM3, are pin shared with pins PD0~PD3, the function of which is
chosen using the PWM registers. Pins PD4~PD7 are pin-shared with INT0,
INT1, TMR0 and TMR1 respectively. HT56R62 has three PWM pins and PD7
is not available.
OSC1, OSC2 are connected to an external RC network or external crystal,
determined by configuration option, for the internal system clock. If the RC
I Crystal or RC system clock option is selected, pin OSC2 can be used to measure the sys-
O
or EC
tem clock at 1/4 frequency.
EC is external clock mode, we can connect OSC1 pin with external clock
source directly.
I
O
32768Hz
OSC3 and OSC4 are connected to a 32768Hz crystal oscillator to form a real
time clock for timing purposes and for fSUB or fSL. This 32768Hz crystal is dis-
abled/enabled by configuration option.
