Microchip's KSZ8873MLLJ is the industrial version of the KSZ8873MLL that operates over the extended temperature range of -40°C to +125°C. It is a highly integrated 3-port switch on a chip IC. Low power consumption, advanced power management and QoS features enable a new generation of low port count, cost-sensitive and power efficient 10/100 Mbps switch systems.
Features
- Advanced switch features
- Tail tag mode (1 byte added before FCS) support at port 3 to inform the processor which ingress port receives the packet and its priority
- MAC MII interface supports both MAC mode and PHY mode
- Comprehensive configuration register access
- Serial management interface (MDC/MDIO) to all PHYs registers and SMI interface (MDC/MDIO) to all registers
- High-speed SPI (up to 25 MHz) and I2C master Interface to all internal registers
- QoS/CoS packet prioritization support
- Switch monitoring features
- MIB counters for fully-compliant statistics gathering 34 MIB counters per port
- Loop-back support for remote diagnostic of failure
- Low-power dissipation
- Full-chip hardware/software power-down and per port software power down
- Energy-detect mode support
- Per port based software power-save on PHY (idle link detection, register configuration preserved)
