The
FDC37C78
Floppy
Disk
Controller
incorporates Software Configurable Logic (SCL)
for ease of use. Use of the SCL feature allows
programmable system configuration of key
functions of FDC
The FDC37C78 does not require any external
filter components, and is, therefore easy to use
and offers lower system cost and reduced board
