The WD177X-00 is Floppy Disc Controller (FDC) IC family with 3 members with little differences. It can use single density (FM), or double density MFM modulation. The chips have an internal digital data separator and write precompensator circuits, eliminating the need for external passive components. | The WD177X-00 is Floppy Disc Controller ([[FDC]]) IC family with 3 members with little differences.
