A continuación se muestra una tabla con las conexiones "pin a pin" sugeridas para integrar el TPS23756, el STM32F072 y el PLC Modem IC dentro del marco de PoE++:

Table

ID Conexión	Desde (Dispositivo, Pin)	Hacia (Dispositivo, Pin)	Función / Descripción
1	TPS23756 – CTRL_EN	STM32F072 – GPIO_EN	Línea de habilitación: el microcontrolador activa/desactiva la salida PoE mediante este control.
2	TPS23756 – STATUS/Fault	STM32F072 – GPIO_STATUS	Línea de estado: se envía una señal de monitorización (estado o fallo) del controlador PoE al microcontrolador para supervisión.
3	STM32F072 – SPI_MOSI	PLC Modem IC – SDI (MOSI)	Comunicación SPI: salida de datos del MCU hacia el transceptor PLC para modular la señal.
4	STM32F072 – SPI_MISO	PLC Modem IC – SDO (MISO)	Comunicación SPI: línea de datos del transceptor PLC hacia el MCU para la recepción de información.
5	STM32F072 – SPI_SCK	PLC Modem IC – SCLK	Reloj de SPI: sincroniza la transferencia de datos entre el MCU y el transceptor PLC.
6	STM32F072 – SPI_CS	PLC Modem IC – CS	Selección del dispositivo: activa la interfaz SPI del transceptor PLC (chip select).
7	TPS23756 – VOUT (ruta de PoE)	PLC Filter/PLC Modem IC – VDD	Suministro de potencia: la salida PoE se dirige al circuito de filtrado/acoplamiento y suministra la energía necesaria para la modulación PLC.
8	Todos los dispositivos – GND	Todos los dispositivos – GND	Conexión a tierra común: garantiza una referencia de potencial uniforme para todo el sistema.

Notas adicionales:

Los nombres de los pines (por ejemplo, CTRL_EN, STATUS/Fault, SDI o CS) son sugerencias basadas en una función típica; se deberán confirmar con los respectivos datasheets y esquemas de referencia de cada IC.
Se recomienda utilizar bloques de desacoplamiento y redes de filtrado en el camino de potencia (especialmente en la conexión de PoE hacia el PLC Modem) para aislar efectivamente la señal de comunicación de la alta potencia.
Es importante que el microcontrolador (STM32F072) comparta una interfaz de comunicación SPI robusta para la coordinación entre la supervisión del PoE++ y la gestión de la comunicación PLC.
Todas las conexiones deben tener en cuenta la correcta referencia de tierra.

Si deseas conectar redes (cableado) entre estos dispositivos en el proyecto, indícalo para proceder a definir el net conectivo.
