Hi,
Additional questions from customer:
1. What is the sleep mode for DSP 5504? We want the mode with minimum power consumption. In the data sheet I have found "RTC clock only mode". Is it mode with minimum power consumption? What is status all I/O in this mode? What others mode are possible.
2. Is RTC 32.768 kHz must perform during sleep mode?
Rephrase the question: We plan to connect t 32.768Khz crystal RTC to the 5504. We also want to use the RTC_OUT output clock 32.768Khz for other application. Our question is if this output exist also when in deep sleep mode?
3. How does DSP moves to sleep mode and how does it go back to active mode?
4. How pins WEAKUP, XF, INT0, INT1 may be use?
5. According to spec DSP should be powered in sequence: first Vcore=1.3V and after VCC for I/O, for example 3.3V. What is minimum delay between Vcorr and VCCio power up?
10X!
