Actually we are using LPC54608 Controller to interface 10 types of devices through serial ports. But the customer has asked me that, what is the lifetime of your major components in the product. In my routing product LPC54608 Controller is the major component. Please provide any test results of LPC54608 lifetime related.
Can you spicify which specify life your customer need?
Sorry we haven't the test results of LPC54608 lifetime related.
All the quality information for LPC54608 can be found on LPC54608J512ET180 Product Information|NXP
In absence of those parameters, I would take the Flash data retention time as first approximation.
And if the application includes IAP, the estimated number of erase/write cycles vs. the guaranteed number.
Under average load and little deviation from moderate temperatures, an average MCU hardly fails for electrical reasons.
Elevated temperature, e.g. like those defined for automotive environments, will decrease the lifespan (both electrically, and Flash code fails).
Increased elevation (i.e. increased cosmic radiation) will result in more pseudo fails (Flash/RAM corruption).
