Part Number: TMS320C5515
We are looking at an application where we would want the C5505 DSP to sleep for long periods of time (up to several days) and wake up on receipt of an interrupt or via wake on motion.
I have been combing through datasheets to try to figure out how to accomplish this and the best option that I see is to put the DSP in “idle” mode where everything but the real time clock (RTC) is shut down. Upon receipt of an interrupt, the RTC can wake up the DSP. Is this the way to accomplish this? I used the C5515 Power Estimator and in RTC only mode, the DSP only consumes 165mW so this would be great if that can be implemented.
Is there an application note or technical document that could detail how to accomplish this?
