KSZ8851-32MQLI Application Field and Working Principle

The KSZ8851-32MQLI is an integrated device designed for low power, low voltage network applications. It is a low-power and cost-effective single-chip solution for Ethernet-based designs requiring extensive throughput, data control, and system debugging capability. The device is suitable for industrial, consumer and automotive applications.The product integrates an Ethernet physical layer transceiver, an embedded 32-bit microcontroller and supporting peripherals such as an SPI master interface, smart card hardware, and an integrated SRAM controller. The device supports full and half duplex operation, with an integrated media access control (MAC) engine that provides full TCP/IP network protocol support. The integrated microcontroller takes care of all the low-level protocol functions, while providing a rich set of peripheral interfaces that allows direct connection to the host processor.The transceiver operates at 10 mbps, 100 mbps, and gigabit Ethernet rates, supporting both IEEE 1588 and 802.3 standards. It also supports a wide range of data rates ranging from 10 Mbps to 1000 Mbps for full-duplex operation. The transceiver supports automatic rate negotiation, optical interface and DC power management. The device is designed to support a wide variety of media, including twisted-pair cable, optical, coaxial and still other media.The device\'s embedded microcontroller allows for full TCP/IP protocol operation, with a built-in media access control (MAC) engine and on-chip SRAM. This allows for 802.3 protocol support as well as support for TCP/IP, IPv4 and IPv6. The SRAM interface supports up to 32KB of data.The device also provides an SPI master interface, which allows for direct connection to a host processor. It supports 8-bit or 16-bit transfers, and supports a wide variety of clock speeds. The SPI ports can be configured for either general purpose use or direct access to the embedded eSRAM controller.The integrated smart card sub-system contains a hardware SMBus and slave interface. This supports the Smart Card Consortium standards and allows for direct connection to Smart Cards and other secure storage devices.Overall, the KSZ8851-32MQLI is a highly integrated, low-power and cost-effective solution for Ethernet-based designs requiring extensive throughput, data control, and system debugging capability. It is suitable for a wide variety of applications, ranging from industrial and consumer to automotive. The device\'s rich set of supporting peripherals, along with its low-power consumption, make it an ideal choice for a variety of embedded applications.
