140ms reset timeout — sizing the power-up sequence
The 140ms minimum reset timeout gives the supply rail and oscillator time to settle before the processor starts executing code. For most MCUs and FPGAs, this is long enough to cover the power-good assertion of a typical LDO or DC-DC converter. If your design has a slow-start converter or a large bulk capacitor on the rail, verify that the 140ms window is sufficient — otherwise the processor may begin operation before the supply is fully stable.
Active lifecycle — no obsolescence concern
It is ROHS3 compliant, so it meets the latest EU directive requirements. For new designs or ongoing production, this part is a straightforward BOM line to maintain — no last-time-buy planning or substitution needed.
