Mesh Sensor

Purpose

The Mesh Sensor is a mixed-signal IP detecting the enclosure tampering by monitoring its resistivity level at multiple points.

Features

▪ fully-integrated low-power mesh sensor;
▪ 16 multiplexed impedance sensing inputs (customized on request);
▪ 2 latched alarms signals per sensing input:
− low detection threshold;
− high detection threshold.
▪ 16 multiplexed alarm output pairs;
▪ alarm flag test inputs;
▪ power supply voltage range: nominal core voltage ±10%;
▪ operating junction temperature range: -40°C to 125°C;
▪ electrical characteristics of a 65 nm CMOS implementation:
− startup delay shorter than 60 µs;
− detection time faster than 100 µs;
− typical operating current lower than 4 µA;
− silicon area smaller than 0.1 mm².
▪ silicon proven in a 65 nm CMOS process.

Deliverables

▪ GDSII stream and layer map file;
▪ Library Exchange Format (LEF) file;
▪ Circuit Description Language (CDL) netlist;
▪ Liberty Timing File (.lib);
▪ VHDL behavioral model;
▪ design specification.
