Raspberry Pi RP2350-based W6300-EVB-Pico2 Ethernet board supoprts 80+ Mbps data rates thanks to WIZnet W6300 QSPI Ethernet

WIZnet has recently introduced the W6300-EVB-Pico2, a Raspberry Pi RP2350-based Ethernet board featuring the new W6300 QSPI Ethernet controller, designed to achieve Ethernet data rates exceeding 80 Mbps. Designed for applications that need higher-speed wired Ethernet connectivity with low MCU overhead. This can now be achieved thanks to its built-in TCP/IP Offload Engine (TOE).

The most interesting features include a high-speed QSPI interface, 10/100 Mbps Ethernet support with integrated PHY, 64KB total SRAM for 8 independent sockets, dual-stack IPv4/IPv6, Wake-on-LAN support, low power modes, and secure boot with Arm TrustZone. The board features 520KB internal RAM, 16 Mbit SPI flash storage, a USB Type-C port for power and data, UART, SPI, I2C, PWM, ADCs, and PIO blocks, and supports a wide temperature range of -20°C to +85°C, with CE/FCC certifications. Its applications include IoT devices, industrial controllers, networked sensors, and embedded systems needing reliable Ethernet networking with minimal processing burden on the microcontroller.

The documentation for the RP2350-based Ethernet board is still in progress. And at the time of writing, there’s no sample code yet, but WIZnet usually provides C examples, and Arduino libraries often follow later.

WIZnet recently announced the W6300 chip on X, so it should be available soon. The W6300-EVB-Pico2 board will likely launch shortly after. While not listed yet, both the chip and board should eventually appear on WIZnet’s online store.
