TLC5940PWP Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 25 MHz. However, it's recommended to use a clock frequency between 10 kHz to 10 MHz for optimal performance.
  • To ensure proper initialization, the TLC5940PWP requires a power-on reset (POR) pulse on the RST pin. The POR pulse should be at least 1.5 ms wide and have a voltage level between 0.8 V and 2.5 V.
  • The GSCLK pin is the grayscale clock input. It is used to update the grayscale data in the TLC5940PWP. The frequency of the GSCLK pin determines the grayscale update rate.
  • The brightness of the LEDs can be controlled by adjusting the grayscale data sent to the TLC5940PWP. The grayscale data is an 8-bit value that determines the duty cycle of the PWM signal driving the LEDs.
  • The maximum current rating of the TLC5940PWP is 120 mA per channel. However, the total current drawn from the device should not exceed 600 mA.
