HL1606

www.DataSheet4U.com HL1606 DESCRIPTION HL1606 is a LED driver IC with SPI controlled. We can get “complex mode changes” by fewer data. FEATURES NMOS output SPI controlled，plus synchronization speed control port: S-I PWM output,frequency:500Hz With a internal “change model” unit，only data calls, reducing the amount of data. Speed control bit，can speed up “changes in a pixel” rate of 2 times. Latch enable bit，concatenated string at a point can be read or not read data. Built-6 road, drive two pixels（three-output get a pixel） Pin definition No. 1 2 3 4 5 6 Name S-I D-I CK-I L-I L-O CK-O Description Sync / speed clock input Data input Clock input Latch signal input Latch signal buffer output Clock buffer output No. 7 8 9 10~12 13~15 16 Name D-O S-O GND B3~B1 A3~A1 VDD Description Data buffer output Sync / speed clock buffer output GND 3 way drive output 3 way drive output VDD Data format D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 D16 HIGH A1~A3 LED Control data-1 B1~B3 LED Control date-2 Data format of A1-A3 LED Control data-1(B1-B3 LED Control data-2 can refer it) D1（D9） D2（D10） D3（D11） D4（D12） A2（B2）Control bit D5（D13） D6（D14） A3（B3）Control bit D7（D15） D8（D16） Control bit of speed Latch enable bit A1（B1）Control bit Page 1 / 6 www.DataSheet4U.com D2=0、D1=0 A1 Light out D2=0、 D1=1 A1 Light on D2=1、D1=0 A1 fadein D2=1、D1=1 A1 fadeout D4=0、 D3=0 A2 Light out D4=0、D3=1 A2 Light on D4=1、D3=0 A2 fadein D4=1、D3=1 A2 fadeout D6=0、D5=0 A3 Light out D6=0、 D5=1 A...
