R3200 Series
Reset Timer IC

Product Specifications

The R3200 is a reset timer IC with two input signals for mobile equipment which require long interval for reset sequence. The long interval prevents unexpected resets caused by accidental key operations. The R3200 has two active-low input pins (SR0 and SR1) which generate reset signals after output delay time when both active-low input pins are activated at the same time. The R3200 has two versions that are different in output delay time settings and output release method.

R3200x001x: Output delay time is selectable from 7.5 s or 11.25 s typ. by connecting the DSR pin to either GND or VDD. A reset signal can be released by making one of the active-low input pins high.

R3200xxx2x, R3200L052B, 053B or R3200L064A: Output delay time is fixed. A reset signal will be released automatically after output release time. Or, by making one of the active-low input pins high, a reset signal can be released before output release time.

The R3200 provides ultra-low supply current while a reset signal is remaining active or after being sent out. The R3200 is offered in a 8-pin DFN(PLP)2020-8B package or a 8-pin DFN1216-8 package.

TIMING CHART

R3200x001x

R3200x002x/R3200L052B,053B,064A

When both SR0 and SR1 voltages become "L", the timer operation will start. After the output delay time (tDELAY), the reset signal will be outputted.
001x : While the reset signal is being outputted, either SR0 or SR1 voltage becomes “H”, the reset signal will be canceled. Until either SR0 or SR1 voltage becomes “H”, the reset signal will be continually outputted.
002x/052B/053B/064A : After reset signal is being sent 0.234s/0.313s/0.078s/0.1875s, it will be released automatically, or if either SR0 or SR1 becomes "H", the reset signal will be canceled.
