The ODT-PVT-ULP-001C-3 is an ultra-low power temperature, voltage and process monitor designed in a 3nm CMOS process. This IP operates over the entire temperature range of -40°C to 150°C. The temperature monitor achieves ±4°C temperature accuracy without trim and ±1°C temperature accuracy after a single room temperature trim.  The voltage monitor supports four differential or single-ended inputs with a voltage range up to ±0.75V. A one-shot mode allows user to initiate an on-demand temperature or voltage measurement.  When not operating, the entire block enters a low power standby mode. The included process monitor provides information on process variation of core P, N as well as I/O P, N MOS devices in an easily readable digital format.
