CC2541: wakeup time after power down

Lenio Cacula

Part Number: CC2541

What is the time it takes for the 8051 core to be available for commands, that is, the MCU reset/shutdown to active? This is for comparison with the CC2340Rx -- table 8.18.2, wakeup timing.

Thank you!

Hi Lenio,

Information like this can be found in the CC2541 data sheet. Data sheets for TI products can be found in the product folders on TI.com. For the CC2541 the direct link is: https://www.ti.com/product/CC2541 For convenience I've pasted the relevant section below:

Best Regards,

Jake

These are the timings in between different power modes, not from reset.

Hi Lenio,

To the extent that the device was specified and characterized, the data is available in the data sheet. Unfortunately it looks like at the time (roughly 2011) the reset to active timing was not specified. To be doubly sure I went back and looked at the historical characterization data and there is no specification for reset to active time in the raw data. I reviewed other parts in the family and they also do not include this data.

br,

Jake
