AX88796C网络接口电路图
The AX88796C is a SPI or non-PCI Ethernet controller with low power, low-pin-count and variable voltage I/O for the Embedded and Industrial Ethernet applications. The AX88796C supports 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 also provides an alternative SPI slave interface for MCUs with SPI master for simplifying host interface connection. The AX88796C integrates on-chip Fast Ethernet MAC and PHY, which is IEEE 802.3/802.3u 10BASE-T/100BASE-TX compatible, and 14KB embedded SRAM for packet buffering to accommodate high bandwidth applications. The AX88796C offers a wide array of features including support for advanced power management, 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 supports two operating temperature ranges, namely, commercial grade from 0 to 70 °C and industrial grade from -40 to 85 °C. The small form factor of 64-pin LQFP package helps reduce the overall PCB space. The programming of AX88796C is simple, so the users can easily port the software drivers to many embedded systems very quickly.
