Temperature Monitor

Purpose

The Temperature Monitor is a fully integrated analog IP supervising the junction temperature (TJ) of the device.

Features

▪ fully-integrated analog IP monitoring the junction temperature (TJ);
▪ two active-high alarm signals:
− one alarm signal indicating that TJ < TJ_low;
− one alarm signal indicating that TJ > TJ_high.
▪ two trimming methods of the temperature detection thresholds:
− ±1.5°C accuracy method requiring temperature steps at TJ_low and TJ_high;
− ±5.0°C accuracy method involving only one step at 25°C.
▪ operating junction temperature range: -40°C to 125°C;
▪ minimum/maximum nominal values of the accurate trimming method:
− min(TJ_low) = -38.5°C;
− max(TJ_high) = 123.5°C.
▪ minimum/maximum nominal values of the ambient trimming method:
− min(TJ_low) = -35.0°C;
− max(TJ_high) = 120.0°C.
▪ power-supply voltage range: nominal core voltage ±10%;
▪ typical characteristics of a 65 nm CMOS implementation:
− wake-up time shorter than 50 µs;
− operating current smaller than 50 µA;
− standby current lower than 40 nA;
− silicon area smaller than 0.04 mm².
▪ silicon proven in 130 nm, 110 nm, 65 nm and 55 nm CMOS processes.

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.
