Hello team,
We had few queries regarding MIMXRT1061CVL5B:
1. Can we use standard SPI instead of Quad SPI for interfacing NAND Flash?
2. Is there any max capacity limit for external Flash?
3. If we are using same supply for SNVS and main domain, can only main domain be turned off such that we can achieve low sleep/standby current? Or we need to provide separate supplies for both rails?
4. Can the MCU boot from external NAND Flash? Please share details about the booting process.
Hello Omar,
Thanks for the feedback.
Any pin capable of interrupt can be used as wake-up source from low power modes different from SNVS mode.
Hello Omar,
Thanks for the feedback. I kindly request you to let me know which section of Datasheet or RM has to be referred to know about how many pins are wake-up capable in Suspend Mode.
Hello, I hope you are well.
1. If you plan to use the NAND flash as booting device then it is not possible, for this FlexSPI interface is used.
Standard SPI can be used for data but performance will be limited to LPSPI.
2. It is limited to the available addressing space of FlexSPI on the system memory map.
3. If SNVS is also supplied by the main domain then you will be limited when entering on SNVS low power mode only.
4. Yes, it can boot from NAND Flash but it will not support XIP, please refer to chapter 9.6.2 for more details for booting.
5. Yes, that one pin is only limited to wake the device from SNVS mode but other GPIO can be used as wakeup on other power modes.
Best regards,
Omar
5. Can we have more wake-up pins in any other version which has similar features as this, as MIMXRT1061CVL5B has only 1 wake-up capable pin.
