Ethernet controller interface chip for MCUs with SPI interface

Taiwan based fables chip vendor ASIX Electronics has released AX88796C, a SPI interfaced Ethernet controller chip enabling Microcontrollers and SoC to connect to the LAN through 4 wire SPI interface. The AX88796C enable embedded systems with Ethernet connectivity to transmit/receive data remotely over the network.

The SPI serial interface available on AX88796C requires four lines to interface to a host microcontroller. The AX88796C also supports an alternative 8/16-bit SRAM-like or Address-Data Multiplex host interface with variable voltage I/O, providing a glue-less connection to common or high-end MCUs.

The AX88796C has on-chip IEEE 802.3/802.3u 10BASE-T/100BASE-TX compatible Fast Ethernet MAC and PHY. The AX88796C supports low-power features such as dynamic power management and very low power Wake-on-LAN (WOL) mode. The other features include support for high performance data transfer on host interface, IPv4/IPv6 checksum offload engine, HP Auto-MDIX, and IEEE 802.3x and back-pressure flow control.

The AX88796C is available in both commercial grade (0 Deg C to 70 Deg C) and industrial grade (-40 Deg C to 85 Deg C) versions.
Package: 64-pin LQFP package

The applications suggested for AX88796C includes networked home appliances, building/home automation, industrial control, security systems, and remote control/management applications such as POS, RFID reader, Multi Functional Printer, IP Camera, VoIP, IP STB, digital video recorder, DVD recorder/player, digital media adapter, and IPTV, etc
