3 Guidelines for Extended POH

For extended POH up to 200k POH (greater than 20 years), the same notes apply as listed for 100k POH in the Power-On Hours (POH) section in the AM64x Sitara™ Processors Data Manual and in the Power-On Hours (POH) section in the AM243x Sitara™ Microcontrollers Data Manual.

As noted in the data manuals, AM64x and AM243x achieve an estimated 100k POH with Tj in industrial temperature range of -40°C to 105°C.

Extended POH estimates up to 200k POH are stated in Figure 3-1 for continuous processor operation. An estimated 200k POH can be targeted for systems by maintaining Tj in range of ‐20°C to 85°C. Note that there are estimates from 100k and 200k POH between 105°C and 85°C and between -40°C and -20°C, respectively, that can be utilized for extended lifetime profiling as well.
