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 automotive applications where low-power and
low-voltage operations are essential. The AT93C86A is available in space saving 8-
lead JEDEC SOIC and 8-lead TSSOP packages.
