### **Descriptions:**  
The LM90CIMMX/NOPB is a high-precision digital temperature sensor designed for monitoring system temperatures in computers and other electronic devices. It features both local and remote temperature sensing, with an SMBus/I²C interface for communication with a microcontroller.  

### **Features:**  
- **Dual Temperature Sensing:** Measures both internal (local) and external (remote) temperatures.  
- **Wide Voltage Range:** Operates from 2.7V to 5.5V, suitable for low-power applications.  
- **Programmable Resolution:** Adjustable from 9 to 12 bits for flexibility in measurement accuracy.  
- **Alert Function:** Configurable temperature limits with interrupt output.  
- **Low Power Consumption:** Optimized for energy-efficient applications.  
- **Small Form Factor:** 8-pin VSSOP package for space-constrained designs.  

This information is based solely on the manufacturer's datasheet and specifications.
