93C56 2K EEPROM – Datasheet

The AT93C56 provides 2048 bits of serial electrically erasable programmable read-only memory (EEPROM), organized as 128 words of 16 bits each (when the ORG pin is connected to VCC), and 128 words of 8 bits each (when the ORG pin is tied to the ground). The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential.

The AT93C56 is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead mini-MAP (MLP 2×3), 8-lead TSSOP, and 8-lead dBGA2 packages. The AT93C56 is enabled through the Chip Select pin (CS) and accessed via a three-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon receiving a Read instruction at DI, the address is decoded and the data is clocked out serially on the DO pin.
