Description
The AT93C86 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 AT93C86 is available in space
saving 8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages.
The AT93C86 is enabled through the Chip Select pin (CS), and accessed via a 3-wire
serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK).
