DLPC3478: Supported I2C Speeds

Part Number: DLPC3478
Other Parts Discussed in Thread: DLPC300,

Hey DLP Team,

I have a customer that transitioned from DLPC300 to  DLPC3478 on a project and we have the following inquiry regarding supported I2C speeds. See below!

We transitioned from the DLPC300 to the DLPC3478 and recently realized that the max I2C speed decreased from 400kHz to 100kHz. This is keeping us from being able to switch DLP functionality modes/patterns quickly. Is there any chance that the DLPC3478 will be able to support 400kHz I2C speeds?

Best regards,

Matt Calvo

    Hi Matt, 

    Unfortunately we have only guaranteed functionality at 100kHz, the customer may be able to run at 400kHz depending on their board design, application, and other devices on the bus, however they would need to verify this works on their system.

    Best,

    Maximus
