RDMCF51CN128: Serial to Ethernet Bridge
The most common use of this reference design will be to integrate old MCU projects to the internet. The connection between these legacy microcontrollers will be by SCI and SPI. The MCU used is the MCF51CN128. As a second goal, customers don’t need to know about ETH, or in certain cases, a little knowledge will be required, though enough information is provided for customer education in Lasko Ethernet TCP/IP implementation.
