Micrel, Inc. KS8995MA/FQ 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 • 1.4Gbps high-performance memory bandwidth • 10BASE-T, 100BASE-TX, and 100BASE-FX modes • Dual MII configuration: MII-Switch (MAC or PHY
mode MII) and MII-P5 (PHY mode MII). • IEEE 802.1q tag-based VLAN (16 VLANs, full-range
VID) for DMZ port, WAN/LAN separation or interVLAN switch links • VLAN ID tag/untag options, per-port basis • Programmable rate limiting 0Mbps to 100Mbps,
ingress and egress port, rate options for high and
low priority, per-port basis in 32Kbps increments • Flow control or drop packet rate limiting
(ingress port) • Integrated MIB counters for fully-compliant statistics
gathering, 34 MIB counters per port • 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) • Wire-speed reception and transmission • Integrated look-up engine with dedicated 1K MAC
addresses • 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 • Low power:
− Core: 1.8V − Digital I/O: 3.3V − Analog I/O: 3.3V • 0.18µm CMOS technology • Temperature ranges: • Enable/Disable option for huge frame size up to
1916 bytes per frame • IGMP v1/v2 snooping for multicast packet filtering − Commercial: 0°C to +70°C • Special tagging mode to send CPU info on ingress
packet’s port value − Industrial: –40°C to +85°C • • SPI slave (complete) and MDIO (MII PHY only)
serial management interface for control of register
configuration Applications • MAC-id based security lock option • Control registers configurable on-the-fly (portpriority, 802.1p/d/q, AN.) • CPU read access to MAC forwarding table entries • 802.1d spanning tree protocol • Port mirroring/monitoring/sniffing: ingress and/or
egress traffic to any port or MII • Broadcast storm protection with % 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:
