# W55MH32

#### introduce

​	The W55MH32 chip is a cost-effective system-in-package (SiP) solution with a 32-bit Arm ® Cortex ®-M3 Core core and rich interfaces. It also integrates a TCP/IP offload engine (TOE) using WIZnet's patented full-hardware TCP/IP stack technology. 

​	WIZnet's full-hardware TCP/IP stack solution has been proven in numerous applications over the years, supporting TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE protocols. TOE embeds 32KB of internal cache for Ethernet data packet processing.
