W83601G Application Field and Working Principle

W83601G is a Super I/O chip from Winbond, which is especially designed for providing multiple I/O functions for embedded systems. It is an interface chip that specializes in the connection and response between a variety of embedded components, such as the processor, memory, hard disks, and input/output devices. It\'s an integrated interface that carries out data communication, I/O control, and other functions.

Features of W83601G

• Provides three families of buses, including Enhanced Parallel Port (EPP), Enhanced Data Output (EDO) and Motorola-Type Interrupt Controller (IC).
• Provides up to seven UARTs to support RS-232, RS-232 and RS-422.
• Eight 16-bit timer/counter can be used for pulse width modulated output, frequency measurement and pulse count and pulse arrival measurement.
• It has three general-purpose output ports that can be configured as logic 1, 0 or open circuit.
• The internal SRAM can store up to 256 bytes of data, and supports an extendable programmable interrupt control vector.
• Support the connection of up to eight PS/2 ports.
• Provides real-time clock/calendar with 65 hours of time replacement.
• Provides for the connection of up to four USB ports.

Application Field of W83601G

The W83601G chip is widely used in embedded systems, such as data storage devices, communication devices, and office automation devices. In terms of data storage, it is used for hard disk control and communication, Ethernet control, CD-ROM control, floppy disk control and communication, and so on. In terms of communication devices, it is used for modems, fax machines, ISDN adapters, voice recognition systems, and more. In terms of office automation, it is used for copiers, scanners, printers, fax machines, document tracking systems, and many other products.

Working Principle of W83601G

The W83601G is a general-purpose interface chip that allows multiple devices to communicate with each other by exchanging data and control signals. It uses three families of buses — the Enhanced Parallel Port (EPP), the Enhanced Data Output (EDO) and the Motorola-Type Interrupt Controller (IC) — to enable the connection of multiple components. It also provides a range of configurable I/O ports that can be used to connect different types of devices.

In addition, the chip includes a programmable interrupt controller, which watches for certain signal changes or for when a specified number of characters has been received from a device, and then diverts the attention of the processor from the current task or sends an interrupt signal to trigger it. The chip also includes a Real-Time Clock/Calendar, which records the current date and time and ensures that the system clock always maintains accurate time information.

Finally, the W83601G chip is equipped with a special control block, which allows it to control the communication between the connected devices, issue commands, and manage the data transfer operations. This feature makes the W83601G one of the most powerful and versatile interface chips available.
