W5500 will resist hackers attack and save energy

New „hardwired“ TCP/IP chip from company Wiznet resists attacks, it´s fast and consumes only a minimum energy and host MCU resources.

TCP/IP solutions from company Wiznet are known by its resistance resulting already from their principle . all the solution is hardware-based, thus it´s not possible to change a basic functionality of a device (flooding, spoofing, ...). W5500 outstands by its “modesty” - it only requires a few GPIO pins of a host MCU – thanks to a high speed SPI interface (up to 80 MHz) and it also has a very low power consumption. A result of a small consumption is, that the chip heats up to approx. 40´C at a common operation, in contrast to other similar chips, which usually have 60-70´C at operation. This naturally means a higher reliability, possibility of a more dense placing of components and elimination of problems with overheating of a device built-in into a small enclosure.

Energy saving is also enhanced by Power Down and Wake-on-LAN (over UDP) modes. Single 3,3V are enough for power supply, while inputs are 5V tolerant. Status is indicated on LED outputs (full/half duplex, link speed, active) and the chip contains a built-in OS Linux (kernel 2.4.xx, 2.6.xx, 3.1,xx) & RTOS driver.

In our offer can be found the W5500 chip itself W5500-EVB evaluation board, as well as a ready-made module WIZ550S2E-TTL or WIZ550io. Examples of a real usage of Wiznet chips can be found in the document Wiznet application reference.
