W83627DHG

W83627DHG is a PC99 compliant microcontroller for the Intel ICH bus. It is an integrated – TPC-enabled – integrated device that combines two ASICs (Application Specific Integrated Circuits) in one package. This feature allows the controller to embed both the standard I/O and SMI (Serial Peripheral Interface) on the same I/O pin. The microcontroller integrates several modules that can be used in various applications.

Application field

The W83627DHG integrates a range of functions, allowing it to be used in various types of applications. It is especially suitable for embedded designs, as it has a wide range of capabilities when it comes to interfacing with many types of hardware. The W83627DHG is used for applications such as embedded controller, DMA controller, serial communication, ATX power control, thermal control, BIOS access and more.

The W83627DHG is also a very popular device for PC motherboards due to its integrated SMI and Power Management support. It is highly reliable and offers a wide range of features, such as ACPI compliance, SMBus/I2C interface, temperature monitoring, and more. It can also be used in a variety of other embedded applications, such as motor control and medical device control.

The W83627DHG is also a great choice when it comes to industrial applications. It provides support for the Ethernet standard, which is often used in industrial applications. It also offers robust I/O capabilities, allowing it to be used in a wide range of industrial applications, such as control systems and factory automation.

Working principle

The W83627DHG is a combination of two ASICs in a single package. The first one is the ATX Power Control (APC) ASIC, which is responsible for controlling the power to the motherboard and other peripherals. This chip contains a fixed-length register set that stores the system configuration, as well as power and thermal settings. The second ASIC is the Serial Peripheral Interface (SMI) ASIC, which acts as a bridge between the APC ASIC and the CPU.

The APC ASIC is responsible for handling the power on/off sequencing and temperature monitoring as well as fan speed control. It also contains a range of registers used for configuration purpose. The SMI ASIC is responsible for interfacing the APC ASIC with the CPU through the SMI bus, which is responsible for the in-band communication between the APC ASIC and the CPU.

The W83627DHG also provides support for the I/O systems of the Intel ICH bus. It works with the I/O systems through the associated SMI interface, as well as the SMBus and I/O pin. Both the APC ASIC and SMI ASIC also provide support for thermal control and monitoring. The W83627DHG also works with the ACPI compliant power control systems, as well as the ATX power control feature.

The W83627DHG is a highly integrated device that offers great reliability for embedded systems and PC motherboards. It features a range of features that make it suitable for many types of applications, such as embedded control, DMA controller, serial communication, ATX power control, thermal control and more. It also provides support for the I/O systems of the Intel ICH bus, and for the ACPI compliant power control systems. It is highly reliable and provides robust features that make it suitable for many types of industrial and embedded applications.
