TMS570LS3137: USB Stick Development Kit - clock limit

Michal Timm

Part Number: TMS570LS3137

In the brochure for USB Stick dev kit there is note that all app run on the Dev Kit should be limited to 100MHz HCLK Speed. What is the reason? (TMS570LS3137 limit is 180MHz)

Hello,
The TMS570 USB stick uses TMS570LS31x MCU which supports up to 180MHz, but we recommend to run the MCU below 100Mhz otherwise the SUB stick will get overheated.

Best regards,
Miro

So if there is such a problem, are there any recommendations to avoid overheated this mcu (on custom self made board)?

Hello,
Heat dissipation should be considered in any design. Many factors should be taken in account (like other components that are generating heat, free-air temperature, processor load, housing and so on).
Here is a good explanation about USB stick: e2e.ti.com/.../867108
