Micrel Inc. (Micrel Inc.) launched KSZ8851. KSZ8851 is a single-port embedded control chip with 8/16/32 bit and SPI host interface. The pin of this high-throughput device is compatible with McRaeer's KSZ8841 and KSZ8842 series, and is ideal for many Ethernet applications in the IPSTB, VoIP, and industrial Ethernet markets. The device will be mass-produced in the third quarter of 2008, with a starting price of 1,000 dollars per 1,000 pieces.
Richard Bowers, head of marketing at McRae's Ethernet, noted: "Ethernet has loaded more than 250 million ports since 1999, and there is a continuing need for devices with increasing throughput. McRae's new KSZ8851 provides existing customers The industry ’s highest throughput embedded controller, which also has industry support for the SPI interface (32-pin QFN package) and a small package option for the common bus interface (48-pin LQFP package). "
KSZ8851 integrates a Fast Ethernet MAC / PHY and an 8/16/32 bit common host processor interface and SPI interface. The device has an 18KB internal buffer memory shared between RXQ and TXQ. The buffer memory has a buffer capacity of 12KB in the receive queue and 6KB in the send queue. With pin compatibility with McCrell's existing KSZ8841MQL and KSZ8842MQL series, the device can provide 80Mbps or higher performance. The solution supports Big-Endian and Little-Endian processors, and also supports IPv4 / IPv6 checksum generation and verification. These functions greatly reduce the use of CPU and improve the overall performance of the system. Through energy detection mode, programmable 3.3V / 2.5V / 1.8V IO options and an operating temperature range of minus 40 degrees Celsius to 85 degrees Celsius, KSZ8851 also provides designers with more powerful power management functions. Finally, the device is available in a variety of packages, including a 128-pin PQFP package, a 48-pin LQFP package, and a 32-pin QFN package.
