The ODT-PVT-ULP-001C-12nm is an ultra-low power temperature, voltage and process monitor designed in a 12nm CMOS process. This IP operates over the entire temperature range of -40°C to 150°C. The temperature monitor achieves ±4C temperature accuracy without trim and ±1C temperature accuracy after a single room temperature trim. The voltage monitor supports four differential or single-ended inputs with a voltage range up to ±1.8V. 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.
