The W83627EG is a highly integrated Super-I/O (Input/Output) development chip designed for a wide variety of personal computer applications. It is a single chip solution for I/O, thermals, power management, clock generator, and embedded controller functions. The versatile features and integrated components of the W83627EG make it a favorite choice for many applications.

Application Field

The W83627EG is primarily used as a bridge between peripheral devices and the system\'s main logic CPU or chipset. This bridge enables devices such as serial ports, parallel ports, game ports, audio ports, modem ports, infrared ports, fan and temperature sensors, and power management functions to be integrated into a single, cost-effective solution. Additionally, this feature-rich chip supports ACPI (Advanced Configuration and Power Interface) version 2 and 3, as well as the upcoming UEFI (Unified Extensible Firmware Interface) version 2. The W83627EG is a commonboard-integrated bridge device which is used in personal computer and all-in-one applications.

Working Principle

The W83627EG uses a highly efficient, single 4-pin clock generator for the integrated peripherals and registers. This clock generator enables the chip to run at speeds up to 400MHz, allowing it to operate at peak performance whatever the load. This clock generator is also self-adjusting, meaning it can minimize the power consumption of its peripherals as the load changes.

The heart of the W83627EG is its integrated embedded controller. This controller sits between the system CPU and the peripherals, managing the flow of data, controlling the power supply, and regulating the clock generation process. The controller is able to support many different functions, such as the management of power, clock, thermal and fan control, system security, direct memory access, and power up and down sequencing.

The W83627EG also includes a versatile set of I/O components, such as six UARTs, four SPI ports, four I2C busses, as well as USB and Serial ATA (SATA) ports. The chip also includes a dozen bits of general purpose I/O and a programmable watchdog timer. These functions allow the user to easily configure the chip for the application.

The W83627EG is a highly integrated development chip designed to be a single-chip solution for I/O, thermals, power management, clock generator, and embedded controller functions. Its combination of features, along with its flexibility and power efficiency make the W83627EG an ideal choice for applications such as personal computers, all-in-one platforms, gaming consoles, and embedded systems.
