Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: TLC6983 Tool/software: Can you please point out what is the right peripheral to be used to drive the LED display controller?
I've not been able to find the right interface either on MCU or CPU.
The EVM seems to use an MSP430 with an…
Hi Nathan Kando,
Nathan Kando said: Are T.high.min and T.low.min static values for all T.cycle, or are they dynamically dependent on T.cycle (without this being indicated in the datasheet)?
the T.high.min and T.low.min are same for all T.cycle which i…
Part Number: TLC6983 When a short occurs for each color in a product designed with 30 SCAN, 30 LEDs light up like GREEN + BLUE. In this case, it is difficult to find which LED has the short circuit. I am looking for defects by removing the LEDs one by one…

TLC6983, TLC6984 , LP5890, LP5891 :
How is V.knee defined?
In the data sheet, the maximum knee voltage is reported as:
V.knee.max @ V.cc = 2.8 [V] @ I.channel = 10 [mA] = 0.30 [V] …

Part Number: TLC6983 Other Parts Discussed in Thread: LP5891-Q1 Do you have a better document for this chip ?
Referring to Figure 8-23 Memory Unit Structure.
I do not understand why there are 16x 48bit data entries per line . and 16 lines = 256 data memories…
Part Number: TLC6983 I'm using TLC6983 for 1mm pitch LED panel.
And only use 11-bit PWM for display because I need a very fase frame rate. (about 2000Hz).
I can't remove the first scan line dim & gradient dim with changing register FC4 [35:38].…
Part Number: TLC6983 Hello,
We are using one TLC6896 to drive a 48x16 monocolor red led matrix. In our schematic we use 6.8k for Rref. We want to achieve 20 mA output current. I am attaching our list of parameters that we are currently using. The problem…
