The X5043S8IZ: After the supply rises above the threshold, the output remains asserted for a minimum of 100 ms to let the system clocks and regulators settle before the processor starts.
ROHS3 compliant per Renesas lifecycle data, so it meets the EU RoHS exemption regime for lead-free assembly without a waiver.
The voltage threshold is 4.38 V. When the monitored supply drops below this level, the active-low reset output asserts and stays low for a minimum 100 ms timeout after the supply recovers.
