Microchip KSZ8794CNXCC-TR: A Comprehensive 4-Port Gigabit Ethernet Switch with Integrated PHYs and Management
The Microchip KSZ8794CNXCC-TR is a highly integrated, feature-rich 4-port Gigabit Ethernet switch designed to address the complex connectivity requirements of modern embedded systems. This system-on-chip (SoC) solution combines a high-performance non-blocking switch fabric, four integrated 10/100/1000BASE-T physical layer transceivers (PHYs), and a comprehensive suite of management functions, making it an ideal choice for a wide array of industrial, consumer, and enterprise applications.
At the core of this device is a fully compliant Gigabit Ethernet switch that supports IEEE 802.1Q VLAN tagging, quality of service (QoS) prioritization with four priority queues, and IGMP v1/v2/v3 snooping for efficient multicast traffic management. The integrated PHYs eliminate the need for external components, significantly reducing board space, system complexity, and overall bill of materials (BOM) cost. This high level of integration is crucial for space-constrained designs.
A key strength of the KSZ8794CNXCC is its versatile management interface. The device can be controlled via a standard SPI (Serial Peripheral Interface) or an I2C bus, providing flexibility for communication with the host processor. This allows for easy programming of the switch's management and control registers, enabling detailed traffic shaping, security features like port-based access control, and comprehensive network monitoring statistics.
The robust feature set is further enhanced by support for Energy-Efficient Ethernet (EEE) according to the IEEE 802.3az standard. This functionality allows the switch to dramatically reduce power consumption during periods of low data activity, a critical advantage for power-sensitive and green technology applications.
Designed for reliability, the KSZ8794CNXCC-TR operates over an extended industrial temperature range, ensuring stable performance in harsh environments. Its combination of integration, management capabilities, and power efficiency makes it a superior solution for applications including industrial automation, network infrastructure, network-attached storage (NAS), digital signage, and multi-port routers.
ICGOOFIND: The Microchip KSZ8794CNXCC-TR stands out as a powerful and efficient networking solution, integrating a complete 4-port Gigabit switch, PHYs, and advanced management onto a single chip to simplify design and accelerate time-to-market for a multitude of connected devices.
