Project description
Overview This patent describes a wired networking path built around three main blocks: a Cortex-M4-class processor, a network controller centered on the WIZnet W6100 hardwired TCP/IP chip, and a power stage that converts 24 V input into the 3.3 V rail needed by the logic. The figures and claims show the processor handling application-layer data, the W6100-side network controller handling Ethernet-facing communication, and the line interface being completed through a transformer and RJ45 connector. Main Content Image generated by gpt The operating method is intentionally narrow. The sequence…
