HL1606 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.

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. Cycle time of change--T 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. Electric parameter V =5V temperature=25 DD ITEM SYMBOL TEST CONDITIONS MIN. TYP. MAX.
