Micren Unveils New Single-Port Embedded Controller Chip


(Wireless News Via Acquire Media NewsEdge)
Micrel, a provider of analog, communications and Ethernet IC solutions,
announced it has launched the KSZ8851, a single-port embedded
controller chip with 8/16/32-bit and SPI host interfaces.

The high throughput device is pin compatible with Micrel's KSZ8841 and
KSZ8842 product families and made for a wide variety of Ethernet
applications in the IPSTB, VoIP, and Industrial Ethernet markets.

The device will be available in production quantities in Q3 2008.

"With more than 250 Million ports shipped since 1999, Ethernet
continues to require higher and higher throughput devices," said
Richard Bowers, Micrel's director of marketing for Ethernet. "Micrel's
new KSZ8851 gives existing customers the industry's highest throughput
embedded controller that also features Industry support for SPI
interface (32-pin QFN) and a small package option for generic bus
interface (48-pin LQFP)."

Micrel noted that the KSZ8851 integrates a Fast Ethernet MAC/PHY with
an 8/16/32-bit generic host processor interface and SPI interface. The

device has 18KB of internal buffer memory shared between the RXQ and
TXQ. The buffer memory on the receive queue is 12KB, while the buffer
memory for the transmit queue is 6KB. Pin compatible with Micrel's
existing KSZ8841MQL and KSZ8842MQL families, the device offers
performance at 80Mbps or higher. The solution supports both Big-Endian
and Little-Endian processors as well as IPv4/IPv6 checksum generation
and checking, the company noted in a release.
