ii) Oscillator
a) Internal clock
The internal logic and the LCD driving signal of ML1001 are clocked either by the built-in oscillator or
from an external clock. When the internal oscillator is used, OEN should be connected to GND and the
OOUT should be connected to FIN. The oscillator will oscillate at 32 kHz and the frequency is
independent in the range of 2.0V < VDD < 6.0V .
b) External clock
When using an external clock, the OEN is connected to VDD then connects the external clock to FIN.
iii) Timing
ML1001 have several frequencies of clock signal for the users to choose for the LCD display clock (ie.
LCLK) and the blink clock (ie. BCLK). They include the following clock signals :
Frequency of Clock Signal at FIN = 32 kHz
2 KHz
1 KHz
500 Hz
256 Hz
128 Hz
4 Hz
2 Hz
1 Hz

1/32
1/64
1/128
1/256
1/8192
1/16384
1/32768

LCLK
BCLK
iv) Segment outputs
ML1001 has 40 segment outputs which should be connected directly to the LCD. If less than 40 segments
are required, the unused segments should be left open circuit. Users can disable the first 1 to 16 segments
and the last 17 to 40 segments by connecting the SEN1 and SEN2 to VDD, respectively. The segment
outputs shall output GND level after disabling it.
v) Common outputs
ML1001 consists of 2 common signals (ie. COM1A & COM1B). These two common signals are the
inversion of the LCLK. The common outputs should be left open-circuit if the outputs are unused. Users
can disable the COM1A and COM1B by connecting the CEN1A and CEN1B to VDD, respectively. The
common outputs will change to GND after disabling it.
vi) Blink
ML1001 has a blink function that users shall connect the BEN to GND and input the blink clock (ie.
BCLK) either by connecting ML1001 output clock signal from Frequency Divider or an external clock
signal. Users shall disable blink function by connecting BEN to VDD.
