PROMISE POR CDR Milestone successfully reached
VTT announces the completion of the radiation hardened POR IP. This low power (<300μA) supervisory circuit monitors up to two power supply voltages, 1.8V/3.3V and takes appropriate actions if a voltage goes out of boundaries. When rising power supply voltage reaches a sufficient level, POR creates 100μs delay before reset signal is released. In undervoltage condition, reset signal is instantly activated. However, short undervoltage spikes are filtered out. Internal reference voltage ensures accurate voltage level detection and hysteresis between released and undervoltage levels.
