 What is the role of the chip in the circuit board?

　 The circuit board is becoming more and more important in today's electronic products. It is equivalent to the lifeblood of electronic products. It is one of the indispensable and important Electronic Components; we all know that the circuit board can really promote the normal operation of electronic components is its circuit connection Various electronic components, because the interconnection of each component can make the PCBA play a normal role, what is their role, today we will introduce the role of the chip.

We all know that the originality electronics IC is the core element in the circuit board. The status of a circuit board is beyond the originality electronics IC; the circuit board can be divided into the north bridge chip and the south bridge chip according to the position of the circuit. The two correspond to different positions and functions; the north bridge chip generally provides support for the type and main frequency of the CPU, the type and maximum capacity of the memory, ISA/PCI/AGP slot, ECC error correction, etc., and it is usually close to the CPU on the motherboard The position of the socket, because the heat of this kind of chip is generally high, so there is a heat sink on this chip.
The South Bridge chip is mainly used to connect to Cable Connectors I/O Connectors and ISA devices, and is responsible for managing interrupts and DMA channels to make the device work more smoothly. It provides support for KBC (Keyboard Controller) and RTC (Real Time Clock Controller). ), USB (Universal Serial Bus), Ultra DMA/33 (66) EIDE data transmission method and ACPI (Advanced Energy Management) support, which is close to the PCI slot.
