The KS8995E is a fully integrated 5-port 10/100 managed Ethernet switch manufactured by Micrel (now Microchip Technology). It is designed for embedded applications that require Ethernet connectivity. The KS8995E integrates all the functions of a 5-port switch, including the MAC (Media Access Control) layer, PHY (Physical Layer), and switch fabric, into a single chip.

Applications

• Industrial Ethernet Switches
• Embedded Networking Devices
• Home Automation Systems
• IP Phones
• Network Appliances

Features

• 5-Port 10/100 Ethernet Switch: Supports 10BASE-T and 100BASE-TX Ethernet standards.
• Integrated PHYs: Eliminates the need for external PHY chips.
• Managed Switch Features: Supports VLANs, QoS, and other management features.
• Non-Blocking Architecture: Ensures high throughput and low latency.
• SPI/EEPROM Interface: Allows for configuration and management via SPI or EEPROM.
• LED Indicators: Provides status information for each port.

Benefits

• Reduced System Cost: Integrated PHYs minimize the need for external components.
• Simplified Design: Integration simplifies the design process and reduces board complexity.
• Improved Performance: Non-blocking architecture ensures high throughput.
• Flexible Configuration: SPI/EEPROM interface allows for easy configuration.
• Robust Functionality: Supports VLANs and QoS for network management.

Additional Details

The KS8995E supports various managed switch features, including VLANs (Virtual LANs), QoS (Quality of Service), and port mirroring. VLANs allow for segmenting the network into logical groups, improving security and performance. QoS allows for prioritizing certain types of traffic, ensuring that critical applications receive the necessary bandwidth. Port mirroring allows for monitoring network traffic for troubleshooting and security purposes.

The KS8995E is typically packaged in a QFP (Quad Flat Package) or QFN (Quad Flat No-Leads) package. It requires a 3.3V power supply and operates over a temperature range of -40°C to +85°C. It is a popular choice for embedded applications that require Ethernet connectivity due to its high level of integration and robust feature set.
