... The AT93C46E is available in space-saving 8- lead PDIP, 8-lead JEDEC SOIC, and 8-lead TSSOP packages. The AT93C46E 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 data output DO pin ...

... The AT93C46E is accessed via a simple and versatile three-wire serial communication interface. Device operation is controlled by seven instructions issued by the host pro- cessor. A valid instruction starts with a rising edge of CS and consists of a start bit (logic “1”) followed by the appropriate op code and the desired memory address location. ...
