2.5 Mission Profile
The key aspects of the mission profile are summarized in the following table:
| Target | Item | Value | Comments |
|---|---|---|---|
| device targets | device lifetime | 15 years | Fifteen years correspond to 130,000 hours of active operation. |
| It may be necessary to adjust the estimated product lifetime per specific operating profile of the application. | |||
| product targets | safety function target | ASIL-ready | Although this manual focuses primarily on ASIL B compliance, a higher system level ASIL rating may be achieved when a subset of features are utilized by the System Integrator. Diagnostic methods described in this document and coverage calculations obtained from the FMEDA can be used as a guide to determine higher compliance levels. |
| total active operation | 130,000 hours | — | |
| maximum time of operation with a start-up reset | >1,000 hours | — | |
| average junction temperature in use environment | — | It is recommended that the System Integrator contacts Microchip to calculate the FIT rate based on the application’s temperature profile. | |
|
FTTI budget | application-dependent | The FTTI budget allocated for the device is use-case specific. | |
| The required FTTI period depends on the application. It is the system designer’s responsibility to define it. | |||
| temperature profile | as per data sheet | — | |
| operating condition | VDD | value = min. 1.71V, max. 1.89V | |
| qualification | AEC-Q100 REVH | Compliant (grade 2: –40°C to +105°C) |
