UM8329BT - Floppy Disk Interface

Download the UM8329BT datasheet PDF. This datasheet also covers the UM8329 variant, as both devices belong to the same floppy disk interface family and are provided as variant models within a single manufacturer datasheet.

Description

The UM8329/B is an MOS integrated circuit designed to complement either the 179X or 8272A (765A) type of floppy disk controller chip.

It incorporates a digital data separator, write precompensation logic, and a head-load timer in one O.3-inch wide 20-pin package.

Features

  • Digital date separator Performs complete data separation function for floppy disk drives Separates FM and MFM encoded data No critical adjustments necessary 5%" and 8" compatible.
  • Variable write precompensation.
  • Internal crystal osci lIator circu it.
  • Track-selectable write precompensation.
  • Retriggerable head-load timer.
  • Compatible with the FDC 179X, 8272A, and other standard floppy disk controllers.
  • SAN-III MOS N-.
