DESCRIPTION
The Microchip Technology Inc. 93C06/46 family of
Serial Electrically Erasable PROMs are configured in a
x16 organization. Advanced CMOS technology makes
these devices ideal for low-power non-volatile memory
applications. The 93C06/46 is available in the standard
8-pin DIP and surface mount SOIC packages. The
93C46X comes as SOIC only.
These devices offer fast (1 ms) byte write and extended
(-40˚C to +125˚C) temperature operation. It is recom-
mended that all other applications use Microchip’s
93LC46.
