“Non-breakable” interface converter combined with MCU? Wiznet is a solution.

In the last period we can see, that producers go on the way of processors combined with interface converters grouped into a single chip. Company Wiznet also goes this way.

At the end of May 2015, Wiznet launched on the market the new W7500, combining the HW TCP/IP interface converter W5x00 with an MCU. W7500 is a solution combining ARM Cortex-M0, 128kB Flash and the HW TCP/IP. It´s suitable for applications where you use TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE. In these devices it´s usually undesired to upgrade SW resulting in resetting a device.MCU W7500 uses HW TCP/IP thus selecting data which arrived from allowed source. W7500 processes only desired data, so “only” 50 MHz is enough. That´s approximately half the power necessary for SW TCP/IP solutions and it also doesn´t require so big Flash and RAM – as illustrated on the picture.

When comparing all data with other MCU, you can notice that with a small power you can make the same things as with the Wiznet solution. This fact is associated with not only reliability and comfort but also with approximately half the price of the chip.

Please note, that parameters mentioned in the table below are substantially lower at SW TCP/IP, while HW TCP/IP is clearly winning.

To make your development easier, Wiznet has its „wikipedia“, where datasheets, schematics, news and user guides can be found.
