🚀 WIZnet Launches W6300: High-Speed Ethernet in a Compact Form
We are excited to announce the official release of the W6300, WIZnet’s newest iEthernet chip that brings together high-speed performance, hardware TCP/IP offloading, and compact form factor—all optimized for today’s demanding embedded applications.
The W6300 is engineered to deliver up to 90 Mbps throughput via a high-speed QSPI interface, making it the fastest SPI-compatible chip in the WIZnet portfolio to date.
⚡ Up to 80 Mbps over QSPI — Ethernet Without the Bottlenecks
The W6300 sets a new benchmark in SPI-based Ethernet chips. By leveraging a Quad SPI interface, it achieves data transfer rates over 80 Mbps, allowing developers to design Ethernet-enabled systems with the speed of traditional parallel interfaces—without the complexity.
This makes the W6300 ideal for applications that require:
High-throughput data logging
Low-latency control systems
Multimedia and real-time streaming
Secure, stable networking in compact embedded devices
🔁 The W5300 Legacy, Reinvented
WIZnet’s W5300 chip has long been known for its high-performance capabilities, with an 8/16-bit parallel bus interface and robust TCP/IP hardware stack. However, the W5300 comes in a large 100-pin LQFP package, limiting its use in compact designs and requiring more complex PCB routing.
With the W6300, we’ve redefined performance for modern embedded systems:
Feature | W5300 | W6300 |
|---|---|---|
Interface | 8/16-bit Parallel Bus | High-Speed QSPI (80 MHz) |
Max Throughput | Up to 80 Mbps | Up to 90 Mbps |
Package | 100LQFP | Compact QFN48 / LQFP48 |
Socket Channels | 8 | 8 |
Protocol Support | IPv4 only | IPv4 & IPv6 |
The W6300 brings similar high-performance networking in a smaller, easier-to-integrate form, using SPI instead of parallel bus for greater design flexibility—especially for MCUs and compact layouts.
🔑 Key Features of the W6300
