TLC5943: Grayscale (GS) data write frequency

Hi Ishraq,

    Q1: For the grayscale (GS) data in TLC5943, how frequently can we write it in application? For example, change the GS value every 5 seconds? Will this operation damage the device?

    No problem for changing the GS value every 5 seconds. No.

    Q2:  To be clear, does this mean we can write the GS data every 30 ns when using the max freq? There is no min mentioned on the datasheet, but is it possible to achieve the desired 5 seconds by adjusting the GSclk?

    The date transfer rate is controlled by SCLK(Max 30MHz) (GSclk is used for PWM control). No problem for 5 seconds @ SCLK=30MHz. Actually, you can achieve approximately 100KHz(1/100000s) data transfer rate @ SCLK=30MHz.
