R3200x Series are reset timer ICs with two input signals for mobile equipments which require long interval.
The Ricoh R3200x Series are reset timer ICs designed for mobile equipment requiring long interval reset signals. These devices feature two active-low input pins (SRO and SR1) that generate reset signals after a specific output delay time when both inputs are activated simultaneously. The series offers two versions: the R3200x001x with selectable output delay times and the R3200x002x with a fixed output delay time.
