The 82077AA floppy disk controller has completely integrated all of the logic required for floppy disk control.
The 82077AA, a 24 MHz crystal, a resistor package and a device chip select implements a PC AT or PS/2
solution. All programmable options default to compatible values. The dual PLL data separator has better
performance than most board level/discrete PLL implementations. The FIFO allows better system perform-
ance in multi-master systems (e.g. PS/2, EISA). The 82077AA is available in three versionsD82077AA-5,
82077AA and 82077AA-1. 82077AA-1 has all features listed in this data sheet. It supports both tape drives and
4 Mb floppy drives. The 82077AA supports 4 Mb floppy drives and is capable of operation at all data rates
through 1 Mbps. The 82077AA-5 supports 500/300/250 Kbps data rates for high and low density floppy
drives.
The 82077AA is fabricated with Intel’s CHMOS III technology and is available in a 68-lead PLCC (plastic)
package.
