Description and Introduction

Integrated 5-Port 10/100 Managed Switch The KSZ8995MAI is a highly integrated 10/100Base-T/TX Fast Ethernet switch controller manufactured by KENDIN (now part of Microchip Technology). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** KENDIN (acquired by Microchip Technology)  
- **Part Number:** KSZ8995MAI  
- **Type:** 5-port Fast Ethernet Switch Controller  
- **Interface:** 10/100 Mbps (MII/RMII)  
- **Ports:** 5 integrated PHYs (4x 10/100Base-T/TX + 1x MII/RMII uplink)  
- **MAC Address Table:** 1K entries  
- **VLAN Support:** Yes (802.1Q)  
- **QoS Support:** 4 priority queues (802.1p)  
- **Power Supply:** 3.3V  
- **Package:** 128-pin PQFP  

### **Descriptions:**  
- The KSZ8995MAI is a single-chip solution for Ethernet switching applications, integrating a 5-port switch with PHYs and an MII/RMII interface.  
- It supports auto-negotiation, auto-MDI/MDIX, and flow control (802.3x).  
- Designed for embedded networking in industrial, consumer, and telecom applications.  

### **Features:**  
- **Integrated PHYs:** 4x 10/100Base-T/TX ports with auto-negotiation.  
- **Uplink Port:** 1x MII/RMII for connecting to an external MAC or processor.  
- **Auto-MDI/MDIX:** Eliminates the need for crossover cables.  
- **Flow Control:** Supports 802.3x full-duplex and backpressure for half-duplex.  
- **VLAN & QoS:** 802.1Q VLAN tagging and 802.1p priority queuing.  
- **Management:** Optional MIIM (MDC/MDIO) for PHY management.  
- **Low Power:** Optimized for power-sensitive applications.  

This information is based solely on the datasheet and technical documentation for the KSZ8995MAI.

Application Scenarios & Design Considerations

Integrated 5-Port 10/100 Managed Switch

Alternative Part Number

  • KSZ8995MA --: Same KSZ8995 family 5-port switch, commercial temperature grade instead of industrial; pin-compatible and functionally equivalent when industrial temp range is not required.
  • KSZ8995XA --: Closely related 5-port managed switch from the same vendor with similar feature set and interface; suitable drop-in option after datasheet verification.
  • RTL8305SB --: Alternative 5-port 10/100 Ethernet switch IC with comparable integration and MAC/PHY features; requires board-level review but is a viable second-source option.
  • KSZ8895MQXI --: Same 5-port integrated switch family from the successor vendor Microchip, similar feature set and industrial temperature rating, often used as a direct replacement.
  • KSZ8864RMN --: 4-port managed switch with comparable MAC/PHY integration and interfaces, suitable when one fewer port is acceptable.
  • RTL8309N --: 9-port 10/100 Ethernet switch controller offering comparable switching functionality and a common alternative in embedded designs.
  • BCM5325 --: 5-port 10/100 managed switch chip with similar integration level, suitable as a functional substitute where firmware porting is acceptable.
