Micrel Inc. is making security, size top priorities in Ethernet chips. The KSZ8842-PMBL, KSZ8841-16MBL, KSZ8842-16MBL and KSZ8893MBL are the newest members of the company's embedded controller family and 3-port switches, all offering small footprint, secure IC-to-ICs over the PCB and ease of manufacturing. According to Micrel, the chips are suitable for numerous Ethernet applications in the automotive, Ethernet switching and industrial Ethernet arenas and complement the traditional solutions offered in a QFP package.

"Industry requirements continue to change rapidly in all markets including the industrial and automotive arenas," noted Richard Bowers, Micrel's director of marketing for Ethernet. "Micrel's new devices now come packaged in FBGA, offering a secure solution in a smaller footprint necessary to meet end users' evolving requirements."

Key features
The KSZ8842PMBL is a 2-port switch with a PCI interface to the host/CPU. It can be configured as a low-latency repeater to allow for 'cut thru' in latency-critical embedded or industrial Ethernet applications. It is Micrel's fourth generation, integration Layer-2 switch that is also fully compliant with the IEEE802.3u standard.

The KSZ8841-16MBL is a single port, mixed-signal controller device offering Wake-on-LAN technology for addressing fast Ethernet applications. It consists of a fast Ethernet MAC controller, 8bit/16bit, generic host processor interaction and incorporates a unique dynamic and utilizable 8Kbit buffer memory for both TX and RX directions in the host buffer interface.

The KSZ8842-16MBL is a 2-port switch with 8bit and 16bit generic host interface to the external CPU. Entirely compliant with the IEEE802.3u standard, the device can also be configured as a low-latency repeater to allow for 'cut thru' in latency critical embedded or industrial Ethernet applications. In Industrial applications, the solution runs in half-duplex mode.

Finally, the KSZ8893MBL is a highly integrated Layer-2 managed, high-speed non-blocking switch that contains two patented mixed-signal, low power technology 10/100 transceivers and three MAC units. Designed for low port count, cost-sensitive 10/100Mbit/s switch systems, it offers an extensive feature set that includes rate limiting, tag/port-based VLAN, QoS priority, MIB counters, RMII/MII/SNI and CPU control/data interfaces to effectively address both current and emerging fast Ethernet applications
