Part Number: TLC5958
Other Parts Discussed in Thread: TLC6946

Hello,

I am designing a board that uses 9 TLC5958 ICs in Daisy chained. Can you please suggest me the Micro controller that is compatible with the TLC5958.

Regards,
Jaswant

    Hello Jaswant,

    We don't suggest to use MCU to control this LED drivers.
    It is difficult to use MCU to drive TLC5958, since the interface of this device is not the standard SPI interface, it has LAT/SCLK/SIN. If using MCU GPIO, the code will be very complex and transferring speed will be very low.

    Pls let us know if you have more concern, thanks.
    Regards,
    Shawn.

    Hi Shawn,

    Yes you are Right, transferring speed is very slow when i am driving TLC5958 from GPIOs. If not use the MCU than what else i can use to drive TLC5958 ICs. Kindly suggest me the appropriate processor to Drive TLC5958 48 channel IC .

    Regards,
    Jaswant.

    Hi Jaswant,

    We suggest to use FPGA to drive this LED driver device.
    We have tried to use MSP432E401, the maximum system clock can approach to 120MHz, I have used to communicate with TLC6946 before, but I have not evaluate to communicate with TLC5958. If you are interested, you can apply this Launchpad, and have a try.

    Thanks.

    Regards,
    Shawn
