Power-On Reset
This table lists the performance characteristics of the on-chip power-on reset circuit over the full range
of process variation, operating temperature and supply voltage.
T
The eCOG1X has an internal supply voltage sense circuit used for the power-on reset function. It is
designed for use with nominal power supply voltages between 1.62 and 1.98V and provides a reset
indication when the supply voltage is below 1.55V.
The reset output is active low and has an open-drain driver. On the smaller QFN package variants, the
power-on reset circuit output signal is available on the bidirectional nReset pin. On the larger 208BGA
package, it is available on the Reset_Out pin, and in normal use this is connected externally to the
Reset_In pin. External circuits to support additional reset input signals from a user pushbutton or
hardware watchdog may be connected to the nReset or nReset_Out pin, provided they have an open-
drain output.
