CM1414ff – Power-On Reset Threshold (1.6V–1.8V), Low Current (1.5μA)

Power Management

This macro-cell is a low consumption Power-On Reset (POR) core designed for SilTerra 0.18μm CL180GH5 5V CMOS technology.

The threshold sensing voltage ranges from 1.6V to 1.8V (default is 1.65V). A hysteresis of 100mV is added to avoid false reset glitches in noisy supplies.

The POR requires an 1.2V temperature compensated bandgap voltage and 240nA current reference, which can be implemented using CM1215ff IP.

The core is easily retargeted to any other 5V CMOS technology.
