One of Winbond's popular series of I/O chips, the W83877F integrates a disk drive adapter, serial port (UART), parallel port, IDE bus interface, and game port decoder onto a single chip. The W83877F is an enhanced version of the W83777F, with additional powerful features such as configurable plug-and-play registers for the whole chip and infrared support in one of the serial ports.
The disk drive adapter functions of the W83877F include a floppy disk drive controller compatible with the industry standard 82077/765, data separator, write pre-compensation circuit, decode logic, data rate selection, clock generator, drive interface control logic, and interrupt and DMA logic. The wide range of functions integrated onto the W83877F greatly reduces the number of components required for interfacing with floppy disk drives. The W83877F supports four 360K, 720K, 1.2M, 1.44M, or 2.88M disk drives and data transfer rates of 250 Kb/S, 300 Kb/S, 500 Kb/S, and 1 Mb/S.
The W83877F provides two high-speed serial communication ports (UARTs), one of which supports serial Infrared communication. Each UART includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability, and a processor interrupt system.
The W83877F supports one PC-compatible printer port. Additional bidirectional I/O capability is available by hardware control or software programming. The parallel port also supports the Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP).
The W83877F supports two embedded hard disk drive (AT bus) interfaces and a game port with decoded read/write output. The chip's Extension FDD Mode and Extension 2FDD Mode allow one or two external floppy disk drives to be connected to the computer through the printer interface pins in notebook computer applications.
The Extension Adapter Mode of the W83877F allows pocket devices to be installed through the printer interface pins in notebook computer applications according to a protocol set by Winbond, but with upgraded performance. The JOYSTICK mode allows a joystick to be connected to a parallel port with a signal switching cable.
The configuration registers support mode selection, function enable/disable, and power down function selection. Moreover, the configurable PnP registers are compatible with the plug-and-play feature in Windows 95TM , which makes system resource allocation more efficient than ever.

The W83877TF is an enhanced version from Winbond's most popular I/O chip W83877F --- which integrates the disk drive adapter, serial port (UART), IrDA 1.0 SIR, parallel port, configurable Plugand- Play registers for the whole chip --- plus additional powerful features: ACPI / legacy power management, serial IRQ, and IRQ sharing.
The disk drive adapter functions of W83877TF include a floppy disk controller compatible with the industry standard 82077/765, data separator, write pre-compensation circuit, decode logic, data rate selection, clock generator, drive interface control logic, interrupt and DMA logic. The wide range of functions integrated into the W83877TF greatly reduces the number of components required for interfacing with floppy disk drives. The W83877TF supports four 360K, 720K, 1.2M, 1.44M, or 2.88M disk drives and data transfer rates of 250 Kb/S, 300 Kb/S, 500 Kb/S,1 Mb/S, and 2 Mb/S.
The W83877TF provides two high-speed serial communication ports (UARTs), one of which supports serial Infrared communication. Each UART includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability, and a processor interrupt system. One of the UARTs support infrared (IR) IrDA1.0. Both UARTs provide legacy speed with baud rate up to 115.2K and provide advanced speed with baud rate up to 230k, 460k, and 921k bps which support higher speed Modems.
The W83877TF supports one PC-compatible printer port (SPP), Bi-directional printer port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). Through the printer port interface pins, also available are: Extension FDD Mode and Extension 2FDD Mode allowing one or two external floppy disk drives to be connected. This function is especially valuable for notebook computer applications.
Winbond W83877TF provides functions that comply with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power management through SMI or SCI function pins. One 24-bits power management timer is implemented with the carry notify interrupt. W83877TF also has auto power management mode to reduce the power consumption.
The serial IRQ for PCI architecture is supported, ISA IRQs (IRQ1~IRQ15) can be cascaded into one IRQSER pin. W83877TF also features ISA bus IRQ sharing and allows two or more devices to share the same IRQ pin.
W83877TF is made to fully comply with MicrosoftTM PC97 Hardware Design Guide. IRQs, DMAs, and I/O space resources are flexible to adjust to meet ISA PnP requirement. Moreover W83877TF is made to meet the specification of PC97's requirement in the power management: ACPI and DPM (Device Power Management).
The configuration registers support mode selection, function enable/disable, and power down function selection. Furthermore, the configurable PnP registers are compatible with the Plug-and-Play feature demand of Windows 95TM , which makes system resource allocation more efficient than ever.
Another benefit of W83877TF is that it is pin-to-pin compatible to W83877F, and all of the 100-pin Winbond I/O IC family. Thus makes the design of applications very convenient and flexible.
