**82395SX     Smart Cache                                     12/17/90
***Notes:
date source: TimelineDateSort7_05.pdf.

Also states:  82395SX (8-kilobyte);  82396SX (16-Kbyte);  Extension of
386(TM) Smart cache architecture with two new versions of cache memory
controllers.  Designed for  20-megahertz  Intel386 SX  microprocessor-
based systems

Could not find datasheet, see 82396SX, YMMV.
