A93C56 - 2K (256 X 8 OR 128 X 16) THREE-WIRE SERIAL EEPROM

Features

• The A93C56 provides 2048 bits of serial electrically.
• Three-wire Serial Interface erasable programmable read only memory (EEPROM) organized as 128 words of 16 bits each, when the ORG pin is connected to VCC and 256 words of 8 bits each when it is tied to ground. The A93C56 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). Upon receiving a Read instruction at DI, the address is deco.
