DESCRIPTION
HL1606 is a LED driver IC with SPI controlled. We can get “complex mode changes” by fewer data.
FEATURES
NMOS output
SPI controlledplus synchronization speed control port: S-I
PWM output,frequency:500Hz
With a internal “change model” unitonly data calls, reducing the amount of data.
Speed control bitcan speed up “changes in a pixel” rate of 2 times.
Latch enable bitconcatenated string at a point can be read or not read data.
Built-6 road, drive two pixelsthree-output get a pixel

Description of build-in module
Fadein module
When a data bit is 10(D2D1 or D4D3 or D6D5) and the latch is enable, corresponding output
state of LED is fadein. After get the brightest state, it will keep the state, until the new data input
by effective latch.
Fadeout module
When a data bit is 11(D2D1 or D4D3 or D6D5) and the latch is enable, corresponding output
state of LED is fadeout. After the lights out, it will keep the state, until the new data input by
effective latch.
T Cycle time of change--T
When D7=0,T=Tzc×128 set ,series is 128. For example: When Zc=50Hz,T=2.56s,if every latch
is effective, fadein/fadeout module will resume the change.

Description: There is a “gradual change” mode in HL1606, so D_I only need one set of data”10110000”,
then input ”0” to the end is okay. Clock signal has been sent to CK_I, sent a “1” to L_I after 8 clock signal.
Change once the signal of S_I, the output decline in a series. A clock cycle in S_I,. output is keep in 512Hz
