Description and Introduction

Precision Motion Controller The LM628N-8 is a motion control processor manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** National Semiconductor (NS)  
- **Part Number:** LM628N-8  
- **Type:** Motion Control Processor  
- **Package:** 28-Pin Plastic DIP (Dual In-line Package)  
- **Operating Voltage:** +5V DC  
- **Clock Frequency:** 8 MHz  
- **Digital Resolution:** 32-bit position, velocity, and acceleration  
- **Interface:** Parallel (8-bit data bus)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**
The LM628N-8 is a dedicated motion control processor designed for precise servo motor control applications. It integrates digital PID (Proportional-Integral-Derivative) control, trajectory generation, and encoder feedback processing. It is commonly used in robotics, CNC machines, and automated systems requiring high-precision motion control.

### **Features:**
- **32-Bit Computation:** Supports high-resolution position, velocity, and acceleration control.  
- **PID Control Loop:** Programmable PID filter for accurate servo motor control.  
- **Trajectory Generation:** Computes smooth acceleration and deceleration profiles.  
- **Encoder Interface:** Processes quadrature encoder signals for closed-loop feedback.  
- **Host Interface:** 8-bit parallel bus for communication with a microcontroller or host system.  
- **Programmable Parameters:** Allows customization of control loop parameters (gains, limits, etc.).  
- **On-Chip RAM:** Stores trajectory and control data.  

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