Power-On Reset (POR) - Flexible Threshold (down to 0.9V), Low Power (6µA) - X-FAB 0.35µm

Overview

This macro-cell is a low consumption Power-On Reset (POR) core designed for X-FAB 0.35µm XH035 CMOS technology.

The core has a voltage sense, an internal current bias circuit and two configurable assertion delays (default are > 1µs and > 20µs). The threshold sensing voltage can be configured from 0.9V to 5.5V (default is 3.0V). A hysteresis of 100mV is added to avoid false reset glitches in noisy supplies.

The core is easily retargeted to any other CMOS technology with R-poly devices.
