EOE-W55RP20
Overview
The EOE-W55RP20 is a compact Ethernet MCU module based on the WIZnet W55RP20, integrating a dual-core Arm Cortex-M0+ MCU and a Hardwired TCP/IP Ethernet controller in a small form factor. The module is supplied without application firmware by default, allowing firmware to be configured according to the customer's application requirements. WIZnet can provide ready-to-use or customized firmware for various applications, including Serial-to-Ethernet, multi-port Serial-to-Ethernet, SNMP, and other customer-specific network applications. This approach allows customers to use the same compact hardware platform while selecting the firmware functionality required for their product.

Firmware Options
The EOE-W55RP20 is designed as a flexible hardware platform that can support different firmware configurations depending on the customer's application.
Typical firmware options include:
- Serial-to-Ethernet
- 2-Port Serial-to-Ethernet
- 3-Port Serial-to-Ethernet
- 4-Port Serial-to-Ethernet
- SNMP applications
- Customer-specific Ethernet applications
Serial-to-Ethernet firmware is available as a standard firmware option. For applications requiring multiple serial channels, 2-Port, 3-Port, and 4-Port Serial-to-Ethernet firmware can also be provided upon request. Additional protocols or application-specific functions can also be implemented through WIZnet's custom firmware service.
Custom Firmware Service
WIZnet can configure the EOE-W55RP20 firmware according to customer requirements. The module is not limited to a single predefined application. Customers can select the required communication interfaces, network protocols, and application functions. Examples include:
- Number of serial ports
- Serial-to-Ethernet functionality
- TCP/UDP communication
- Modbus communication
- MQTT communication
- SNMP applications
- Device monitoring and control functions
- Customer-specific network protocols and application logic
Firmware requirements can be discussed and configured with WIZnet according to the target application.
