Description and Introduction

Serial Interface System Hardware Monitor with Remote Diode Temperature Sensing The LM87CIMT is a system hardware monitor chip manufactured by National Semiconductor (now part of Texas Instruments).  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (WU)  
- **Package:** 24-Pin SSOP (Shrink Small Outline Package)  
- **Operating Voltage:** 3.0V to 3.6V  
- **Temperature Range:** 0°C to +85°C  
- **Interface:** SMBus (System Management Bus)  
- **Functions:** Monitors system voltages, temperatures, and fan speeds.  
- **Analog Inputs:** Supports up to 8 voltage inputs and 2 remote temperature sensors.  
- **Fan Monitoring:** Tracks up to 3 fan speeds via tachometer inputs.  
- **Alarm Outputs:** Provides programmable thresholds for voltage, temperature, and fan speed alarms.  

### **Descriptions and Features:**  
- The LM87CIMT is designed for monitoring and managing PC or embedded system health.  
- It includes an on-chip temperature sensor and supports external diode sensors (e.g., CPU thermal diode).  
- Programmable via SMBus for custom thresholds and alerts.  
- Features a 2-wire serial interface for communication with the host system.  
- Provides high-accuracy voltage and temperature monitoring.  
- Includes interrupt and power-saving modes for efficient operation.  

This information is based on the manufacturer’s datasheet and technical documentation.
