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 VCC 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.
