Hello,

Why is the power supply voltage slew rate (1 to 67V/ms) specified as max 67V or less?

For example, it is the same as the reset pulse width when using an external reset IC, and if the reset is released too quickly, the oscillator etc. will not be stable and hardware abnormalities will occur.
Is there a reason why it is stipulated?

Dear all. 
I've used this chip quite a lot, starting from the CY8CKIT-043 schematic and adding peripherals around.
I've seen some units die because of improper handling like hot connection of a connector with power and data lines that does not ensure that the ground is connected first. 
If the chip is totally bricked, it normally draws more current than It should and gets hot. 
If only some GPIOS are damaged due to EOS or ESD you can easily check which one was to blame because the protection diodes are blown or degraded.
However, in my device none of this is happening. It died after being up and running for 3 hours without any obvious external event. The diodes are fine, the chip consumes very little current but all its VSS and VDD (+5V) lines are properly connected. It's like its on a permanent RESET state, but the RESET line is high. I've even tried replacing the quartz crystal thinking that it could have broken due to vibrations but I can't bring the chip to life again, and -what is worse- I don't know what to do to prevent it from happening again!
Any help would be very welcome.
By the way, the device run by the PSOC chip is an Engine Control Unit for a small 4 stroke gasoline engine that powers an unmanned aerial vehicle.

There are many inconveniences because the number of collected data that can be stored in BCP is limited to 10,000.

If you look at the attached image file, you can see the outliers in the actual data on a graph, but it cannot be saved and analyzed.

Regarding some inquiries, it is said that the problem has already been forwarded to the SW team.
Why isn't an improved version released?
Why is data stored only after it is collected? You can just save the data as a file right away...

We ask for a quick resolution.

I am querying the register address and value of chip id of products CY8C4046FNI-T412T and CY8C4046FNI-T452EST,  I do not know whether I have searched correctly.
The register address for chip id we found in the 400T series specification is 0x0FFFF144. Is the chip id address of the 400T series the same?
The corresponding register values are shown in the following two pictures.
I hope someone can help with that. Thank you very much.
