SMIC 0.18um Power-On Reset

Overview

This is a Power-On-Reset circuit that generates a reset pulse when power supply is on. After the power V18 reaches a specific level, i.e., VTR, it will output a logic reset signal with pulse width of tPOR. During this interval, all the logic elements can be initialized to known states. When the power drops to another level VTF, a reset pulse is also generated. The additional input RSTI can force the POR to output a reset signal, therefore, provide a soft reset function.

Key Features

  • Process: SMIC0.18 Logic 1P4M/5M/6M
  • Operating voltage range: V18: 0~2V; V33: 0~3.6V
  • Operating temperature range: -40~125°C
