Microchip ENC424J600快速以太网控制方案

Microchip 公司的ENC424J600和ENC624J600是单独可用的快速以太网控制器,具有工业标准的串行通信接口(SPI)或灵活的并行接口,主要用于以太网络接口. ENC424J600/624J600满足所有用于10Base-T 和100Base-TX以太网的IEEE 802.3规范, 引擎具有RSA, Diffie-Hellman, AES, MD5 和SHA-1算法,数据速率从14Mbps(SPI)到160 Mbps (分类, 16位并行接口).本文介绍了ENC424J600/624J600的主要特性和方框图, 典型以太网变压器连接图和以太网演示板电路图.

The ENC424J600 and ENC624J600 are stand-alone, Fast Ethernet controllers with an industry standard Serial Peripheral Interface (SPI) or a flexible parallel interface. They are designed to serve as an Ethernet network interface for any microcontroller equipped with SPI or a standard parallel port.

ENC424J600/624J600 devices meet all of the IEEE 802.3 specifications applicable to 10Base-T and 100Base-TX Ethernet, including many optional clauses, such as auto-negotiation. They incorporate a number of packet filtering schemes to limit incoming packets. They also provide an internal, 16-bit wide DMA for fast data throughput and support for hardware IP checksum calculations.

For applications that require the security and authentication features of SSL, TLS and other protocols related to cryptography, a block of security engines is provided.
