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 eight 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 Ultra Thin
Mini-MAP (MLP 2x3)
, and 8-
lead TSSOP packages.
