W7500 / W7500P

ARM® Cortex™-M0 based Ethernet MCU
Product Overview

Highly integrated Ethernet SoC for Embedded - IoT Devices

The IOP4IoT W7500x chip is the one-chip solution which integrates an ARM Cortex-M0, 128KB Flash and hardwired TCP/IP core for various embedded application platform, especially internet of things. The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated 802.3 Ethernet MAC (W7500P also include PHY).

The main difference between W7500 and W7500P is whether the 10/100 Ethernet PHY is built-in.

The Hardwired TCP/IP stack supports the TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been used in various applications for more than 15 years. W7500x suits users who need Internet connectivity best.
