For CY62187EV30, data retention should be done in the range of “Ambient Temperature with Power Applied” which is –55C to +125C.

My question is whether the max standby current Isb2 (48uA) is derived by applying the range of “Ambient Temperature with Power Applied”, which is –55C to +125C ?

If not, if it applies “Operating temperature”, which is –40C to +85C, for max Isb2, let me know the “true” max Isb2 by applying the range of “Ambient Temperature with Power Applied”, which is –55C to +125C.

Hi @SOEZ,

 

It is a Maximum Rating; the device won't be damaged if you are within the Maximum ratings, but we don't guarantee the specs will be as per the datasheet.


Thanks,
Ritwick

Hi @SOEZ,

 

The ISB2 spec mentioned in the datasheet has been characterized over the Operating temperature range. For the spec value over the “Ambient Temperature with Power Applied” range, let me check internally and get back to you.


Thanks,

Max Isb2 on the datasheet is 48uA that is x6 greater than typ value (8uA). 
If it is max value still in 85C range, the true max value in 125C range must be enormous. 
Please inform us of your internal assumptions or measurement results.

Hi @SOEZ,

 

As CY62187EV30 is an industrial part, we don’t characterize or test at 125C. We cannot guarantee the operation at 125C. Data retention is guaranteed till 85C only.

 

Thanks,

Ritwick

Please advise what the meaning of the "Ambient Temperature with Power Applied" is. It is shown in the datesheet as the range of –55C to +125C.
