The 8272 is a LSI Floppy Disk Controller (FDC) Chip, which contains the curcuitry and control
functions for interfacing a processor to 4 Floppy Disk Drives. It is capable of supporting either
IBM 3740 single density format (FM), or IBM System 34 Double Density format (MFM) including
double sided recording. The 8272 provides control signals which simplify the design of an
external phase locked loop, and write precompensation circuitry. The FDC simplifies and
handles most of the burdens associated with implementing a Floppy Disk Drive Interface.
