W7500

Figure 1 W7500 Chip

The IOP4IoT W7500 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 Ethernet MAC. 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. W7500 suits users who need Internet connectivity best.

Library and Peripheral Example

Overview

The W7500 provides the CMSIS, driver and Peripheral Example. The W7500 Standard Peripherals library provides a rich set of examples covering the main features of each peripheral. All the examples are independent from the WIZwiki-W7500 platform. Only source files are provided for each example and user can tailor the provided project template to run the selected example with his preferred tool chain.

    • W7500x_stdPeriph_Driver
      • Each peripheral has a source code file W7500x_XXX.c and a header file W7500x_XXX.h. The W7500x_XXX.c file contains all the firmware functions required to use the XXX peripheral.
      • A single memory mapping file, W7500x.h, is supplied for all peripherals. It contains all the register declarations and bit definition. This is the only file that needs to be included in the user application to interface with the library.
