    There is no theoretical limit as long as you can maintain the required timing requirements for the control signals. The more ICs that are connected in series, the slower the system refresh rate. The uP must clock in 288*n bits of data, where n is the number of cascaded ICs. If you cascade 100 ICs and...

    I wanted to confirm the correct sequence for chaining 4 TLC5926 drivers together. Is SDO of chip 1 into SDI of chip 2, etc with SDO of the last chip going back into microcontroller? Also, are CLK and LE connected in parallel to the same pin of the microcontroller with OE set to ground (for constant driving...

    Brigitte Brigitte
    Hello Nikhil, There are several limiting factors with daisy chaining TLC5940 and all of these depend on the application and setup, therefore it is almost impossible to answer correctly where the limit is. Here some limiting factors: - The clock signals are sent to the TLC5940 in parallel and the...

    Hello, My customer wouldlike cascading up to 160 Chips ,60Hz refresh . Datasheet of TLC5945 (SLVS755) , page18 , give F(SCLK) mini = 193 x 160 x 60 = 18 852 800 hz That is far under the Max clock of 30Mhz of TLC5945 . 1> How to explain the sentense page18 : ? <The maximum number of cascading TLC5945...
