Product Description

64 pins version(64QFN 10x10mm)

iMCU W7100A is the one-chip solution which integrates an 8051 compatible micro-controller, 64KB SRAM and hardwired TCP/IP core for high performance and easy development. The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated Ethernet MAC & PHY. The Hardwired TCP/IP stack supports the TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been used in various applications for years.
