Two-port Ethernet device claims a first
The KS8842M is billed as the industry's first two-port Ethernet device and has a third port that can be connected directly to microprocessors through a generic 8 or 16bit bus interface.
Replacing two devices with a single cost-effective, flexible solution, the KS8842M from Solid Sate Supplies is the industry's first two-port Ethernet device and has a third port that can be connected directly to microprocessors through a generic 8 or 16bit bus interface Aimed at embedded and industrial networking applications, the KS8842M addresses the growing need for cost-effective solutions

The MUR range of ultrafast rectifiers from Solid State Supplies have been specifically designed to provide optimised performance of forward voltage drop with a reverse recovery time of 25ns.
Ferroelectric RAM handles repeated rewrites
The FM24C04 4Kbit FRAM serial memory from Solid State Supplies is ideal for nonvolatile memory applications which require frequent or rapid writing.
Not only can the KS8842M replace two single-port Ethernet controllers with one streamlined component, but the flexibility of the I/C provides multiple device functionality and a cost-effective, low power solution.
This makes it ideal for use in real-time Ethernet applications, or for daisychaining devices together in industrial controller applications.
The KS8842M can be configured as a fully managed Layer-2 switch with the third port connected to a host processor, or it can be configured as a repeater for use in latency-critical applications in industrial Ethernet where all packets from one port are broadcast to the remaining two ports, bypassing the lookup tables used in a typical store-and-forward switch architecture.
The device may also be used to replace two single Ethernet controllers with a single KS8842M IC where network traffic is 100% segregated between the two ports.
The KS8842M offers four priority queues to improve quality of service (QoS).
It provides IPv6 MLD snooping capabilities to permit IPv6 packets to be identified and sent to the host processor for further processing.
This provides customers with the flexibility to process IPv4 and IPv6 packets, as well as using the device in triple-play applications.
Auto-MDIXs, a standard feature in all Micrel's Ethernet devices, enables straight or crossover cables to be connected to the device, taking the guesswork away for the end user.
The device also features Link Doctor (LinkMD), a cable diagnostic package that enables diagnosis of common cabling problems resulting in reduced customer calls and IT service requests.
