W55RP20 RP2040 + W5500 Ethernet SiP

The W55RP20 is a WIZnet SiP integrating a Raspberry Pi RP2040 (dual Cortex-M0+) with the W5500 hardwired TCP/IP Ethernet controller in a single QFN68 package. With 2MB flash, 264KB SRAM, a hardwired TCP/IPv4 stack (8 sockets, 32KB/32KB TX/RX buffer), and an embedded 10/100 PHY, it builds compact industrial-Ethernet nodes with no external Ethernet chip. Programmable in C/C++ or MicroPython, with SWD debug.
