Sleep and power saving mode

The IC supports the sleep/wake-up modes for power-saving purpuse. In sleep mode, the built-in oscillator

and associated circuitry will be disabled. The quiencent current of the IC is approximately 1uA(typ.).

Command Setup to enable sleep or wake up mode

When recieving 24-bit 0’s GBR data (that is GREEN [7:0]=8h00, BLUE [7:0]=8h00, RED[7:0]=8h00), in the

meantime, both of the data in 3-bits’ flag and 5-bits’ DIMMING is 8h’A0’ (that is FLAG[2:0]=3b101 and

DIMMING[4:0]=5b00000), the IC will enter sleep mode.

The IC will wake up from sleep mode once receiving the new data with the data of Flag[2:0]、 DIMMING[4:0]

is not 8h"A0"; after wake-up,all sleeping circuits in the IC return to normal working mode within 1ms. Since it takes

1ms for a sleeping the IC returning to normal function mode, it is recommended for a host to wait for 1ms to send

display data and command after issuing a wake-up command.

Sleeep power-saving mode example:

Case 1:

Case 2:

In case 2, while lamp2 is under sleep mode, in the following data transfer process, the state of lamp 2 will be

not changed as long as the 32 bits data for lamp 2 is received with data of Flag[2:0]、DIMMING[4:0] being 8h”A0”.

It means lamp2 will keep in sleep mode as well. In the situation, lamp2 can pass through the remaining data to
