DescriptionIntel ICN82077SL CHMOS Single-Chip Floppy Disk Controller
OverviewThe 82077SL, a 24 MHz crystal, a resistor package, and a device chip select implements a complete laptop solution. All programmable options default to 82077AA compatible values. The dual PLL data separator has better performance than most board level/discrete PLL implementations. The FIFO allows better system performance in multi-master systems (e.g., Microchannel, EISA),The 82077SL is a superset of 82077AA. The 82077SL incorporates power management features while maintaining complete compatibility with the 82077AA/8272A floppy disk controllers. It contains programmable power management features while integrating all of the logic required for floppy disk control. The power management features are transparent to any application software. The 82077SL is available in three versions-82077SL-5, 82077SL and 82077SL-1. 82077SL-1 has all features listed in this data sheet. It supports both tape drives and 4 MB floppy drives. The 82077SL supports 4 MB floppy drives and is capable of operation at all data rates through 1 Mbps. The 82077SL-5 supports 500/300/250 Kbps data rates for high and low density floppy drives.The 82077SL is fabricated with Intel's advanced CHMOS III technology and is available in a 68-lead PLCC (plastic) package.
