LOW POWER CONSUMPTION MODE
S6A0092 provides with sleep mode for saving power consumption during standby period.
Sleep Mode (Power Save Bit ON, Oscillation Bit OFF)
To enter the sleep mode, the power circuit and oscillation circuit should be turned off by using the power save
command and the power control command. This mode helps to save power consumption by reducing current to
reset level.

2. Data written in DDRAM, CGRAM, ICONRAM and registers are remained as previous value.
3. Operation mode is retained the same as it was prior to execution of the sleep mode.
All internal circuits are stopped.
4. Power Circuit and Oscillation Circuit
The built-in power supply circuit and oscillation circuit are turned off by power save command and
power control command.
LCD DRIVER CIRCUIT
LCD Driver circuit has 26 common and 80 segment signals for driving LCD. Data from ICONRAM / CGRAM /
CGROM are transferred to 80-bit segment register serially, and then they are stored to 80-bit shift latch. In case of
2-line display mode, COM1 ~ COM16, COMI1 and COMI2 have 1/17 duty, and in 3-line mode, COM1 ~ COM24,
COMI1 and COMI2 have 1/25 duty ratio. SEG bi-directional function is selected by DIRS input pin, and COM shift
direction is selected by function set instruction "S" bit.
