APPLICATION NOTE 5107

Physical Security Guidelines for DeepCover Secure Microcontroller (Zatara ZA9L0)

By:  Reza Ahmadi

Abstract: This application note explains how to hook up the switch and wire inputs on the DeepCover® Secure Microcontroller (Zatara® ZA9L0) microcontroller unit (MCU). The resistive-type wire meshes are rarely used because of the high current required to drive the mesh drains. The ZA9L0's pulsed sensing feature is used to overcome this barrier.
