Description and Introduction

Universal Serial Bus Full Speed Node Controller with Enhanced DMA Support The USBN9603 is a USB peripheral controller manufactured by Microchip Technology. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Interface:** USB Full-Speed (12 Mbps) compliant with USB 1.1 specification.  
- **Operating Voltage:** 3.3V (±10%).  
- **Package:** 28-pin SOIC (Small Outline Integrated Circuit).  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade).  
- **Clock Frequency:** Requires an external 6 MHz crystal oscillator.  
- **DMA Support:** Includes a dedicated DMA interface for high-speed data transfer.  
- **Endpoint Configuration:**  
  - 7 configurable endpoints (including Control endpoint 0).  
  - Supports bulk, interrupt, and isochronous transfers.  
- **FIFO Buffers:** 256-byte FIFO memory shared across endpoints.  

### **Descriptions:**
- The USBN9603 is a standalone USB peripheral controller designed for embedded applications requiring USB connectivity.  
- It interfaces with microcontrollers or processors via a parallel bus, simplifying USB protocol handling.  
- The chip handles USB signaling, packetization, and error checking, reducing firmware complexity.  

### **Features:**
- **USB Compliance:** Fully compliant with USB 1.1 specifications.  
- **Parallel Interface:** 8-bit multiplexed or non-multiplexed parallel bus for host communication.  
- **Integrated Serial Interface Engine (SIE):** Handles USB protocol layer tasks.  
- **Programmable Interrupts:** Supports multiple interrupt sources for efficient event handling.  
- **Suspend/Resume Support:** Includes low-power modes for USB suspend/resume operations.  
- **Software Configurable:** Endpoint types and FIFO allocation can be adjusted via firmware.  

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