Hardware architecture diagram description

The built-in functional block diagram in the document clearly displays the chip interconnection logic:

The N270 CPU is directly connected to the 945GSE Northbridge, which controls DDR2 memory, graphics output (VGA/LVDS/TV out), and PCIe bus;

North Bridge and ICH7-M South Bridge are interconnected, with South Bridge responsible for SATA, PATA, USB, audio, SPI BIOS, LPC low-speed bus;

LPC bus extension W83627HG Super I/O (serial/parallel/keyboard and mouse), TPM security chip;

PCI bus leads to PCI/ISA bridge and gigabit network port;

The module outputs all peripheral signals externally through four sets of standard ETX connectors X1/X2/X3/X4.
