−
Frame cycle: Selectable from four types (For a clock, a main clock or sub clock can be used.)
−
Driver: Built-in (Internal division resistor), or an external division resistor can be connected to V0 to
V3 pins.
−
Data memory: Built-in 16-byte data memory for display
−
No display selection: Enabled
−
Pin: COM0 to COM3, SEG0 to SEG31, V0, V1, V2, V3 pins are used for general-purpose
ports also and switching is enabled.
SEG23 to SEG31 pins are used as static drive pins (ST0 to ST8) also and switching is
enabled.
VCC can be selected instead of V3.
−
During duty driving, up to 4 common outputs (COM0 to COM3) and 32 segment outputs (SEG0 to
SEG31) can be used.
−
Others: The external division resistor also can block a current when LCD is stopped.
< Static drive >
−
Number: 1 (1-common × 8-segment)
−
Display: Up to 8 element
−
Frame cycle: Selectable from four types (For a clock, a main clock or sub clock can be used.)
−
Pin: ST0 to ST8 pins are used also as general-purpose ports and duty drive pins (SEG23 to
SEG31) and switching is enabled.
−
During static driving, up to 1 static common output and 8 static segment outputs (ST0 to ST8) can
be used.
