xCORE-200 Sleep Modes

Post by PlayingWithWires »

Hi! Do xCORE-200 parts support sleep / low-power modes? Unlike other XMOS datasheets which clearly outline such modes, I was not able to find any mention of them on the XU216-512-TQ128 datasheet.

Thanks!

Hi Tony,

You can set it to sleep mode by setting the clock divider to a fair value; but there is no automatic sleep mode like in the XS1-L, or a low-power standby mode, like in the XS1-U/A.

Cheers,
Henk

It's worth noting that the xCORE-200 can have its clock frequency adjusted without causing a device reboot (unlike previous xCORE families)

Just to elaborate on that - in both cases you can adjust the core clock divider, which divides the PLL down. So you can run at 250 rather than 500 Mhz.

On XCORE200 you can also change the PLL on the fly, slowing it down to, for example, 400 MHz from 500 MHz.
