W83877TF - I/O chip disk drive adapter

Download the W83877TF datasheet PDF. This datasheet also covers the W83-877 variant, as both devices belong to the same i/o chip disk drive adapter family and are provided as variant models within a single manufacturer datasheet.

Description

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 W83.
