The uIP is an open source implementation of the TCP/IP network protocol stack intended for use with tiny 8- and 16-bit microcontrollers. It was initially developed by Adam Dunkels of the "Networked Embedded Systems" group at the Swedish Institute of Computer Science, licensed under a BSD style license, and further developed by a wide group of developers.
This is intended to be used only with microcontrollers that are multiples of 4
This is true, 8 bit and 16 bit are multiples of 4
