DESCRIPTION
The Microchip Technology Inc. 93C56A/B is a 2K-bit,
low-voltage serial Electrically Erasable PROM. The
device memory is configured as 256 x 8 bits (93C56A)
or 128 x 16 bits (93C56B). Advanced CMOS technol-
ogy makes this device ideal for low-power, nonvolatile
memory applications. The 93C56A/B is available in
standard 8-pin DIP and surface mount SOIC packages.
This device is only recommeded for 5V automotive
temperature applications. For all commercial and
industrial applications, the 93LC56A/B is recom-
mended.
