Description
The AT93C86A provides 16384 bits of serial electrically erasable programmable read
only memory (EEPROM) organized as 1024 words of 16 bits each when the ORG Pin
is connected to V
CC
and 2048 words of 8 bits each when it is tied to ground. The
device is optimized for use in many industrial and commercial applications where low
power and low voltage operations are essential. The AT93C86A is available in space
saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP and 8-lead TSSOP packages.
