... Serial E PROM memory devices which are configured as either registers of 16 bits (ORG pin at V (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93C46/56/ 57/66/86 are manufactured using Catalyst’s advanced PIN CONFIGURATION SOIC Package (J) DIP Package (P) ...

... Read Upon receiving a READ command and an address (clocked into the DI pin), the DO pin of the CAT93C46/ 56/57/66/86 will come out of the high impedance state and, after sending an initial dummy zero bit, will begin shifting out the data addressed (MSB first). The output ...

... The clocking of the SK pin is not necessary after the device has entered the self clocking mode. The ready/busy status of the CAT93C46/56/57/66/86 can be determined by se- lecting the device and polling the DO pin. Once cleared, the contents of all memory bits return to a logical “1” ...
