Micrel, Inc. KS8995XA Features
• Integrated switch with five MACs and five Fast
Ethernet transceivers fully compliant to IEEE 802.3u
standard
• Shared memory based switch fabric with fully
nonblocking configuration
• 10BASE-T, 100BASE-TX and 100BASE-FX modes
(FX in Ports 4 and 5)
• Dual MII configuration: MII-Switch (MAC or PHY
mode MII) and MII-P5 (PHY mode MII)
• VLAN ID tag/untag options, per-port basis
• Enable/disable option for huge frame size up to 1916
bytes per frame
• Broadcast storm protection with percent control –
global and per-port basis
• Optimization for fiber-to-copper media conversion
• Full-chip hardware power-down support (register
configuration not saved)
• Per-port-based software power-save on PHY (idle
link detection, register configuration preserved)
• QoS/CoS packets prioritization supports: per port,
802.1p and DiffServ-based
• 802.1p/q tag insertion or removal on a per-port basis
(egress)
• Port-based VLAN support
• MDC and MDI/O interface support to access the MII
PHY control registers (not all control registers)
• MII local loopback support
• On-chip 64Kbyte memory for frame buffering (not
shared with 1K unicast address table)
• 1.4Gbps high performance memory bandwidth
• Wire-speed reception and transmission
• Integrated look-up engine with dedicated 1K unicast
MAC addresses • Automatic address learning, address aging and
address migration
• Full-duplex IEEE 802.3x and half-duplex back
pressure flow control
• Comprehensive LED support
• 7-wire SNI support for legacy MAC interface
• Automatic MDI/MDI-X crossover for plug-and-play
• Disable automatic MDI/MDI-X option
