5 / 9 page 5 93C46/56/57/66/86 Doc. No. 25056-00 2/98 M-1 DEVICE OPERATION The CAT93C46/56(57)66/86 is a 1024/2048/4096/ 16,384-bit nonvolatile memory intended for use with industry standard microprocessors. The CAT93C46/56/ 57/66/86 can be organized as either registers of 16 bits or 8 bits. When organized as X16, seven 9-bit instruc- tions for 93C46; seven 10-bit instructions for 93C57; seven 11-bit instructions for 93C56 and 93C66; seven 13-bit instructions for 93C86; control the reading, writing and erase operations of the device. When organized as X8, seven 10-bit instructions for 93C46; seven 11-bit instructions for 93C57; seven 12-bit instructions for 93C56 and 93C66: seven 14-bit instructions for 93C86; control the reading, writing and erase operations of the device. The CAT93C46/56/57/66/86 operates on a single power supply and will generate on chip, the high voltage required during any write operation. Instructions, addresses, and write data are clocked into the DI pin on the rising edge of the clock (SK). The DO pin is normally in a high impedance state except when reading data from the device, or when checking the ready/busy status after a write operation. The ready/busy status can be determined after the start of a write operation by selecting the device (CS high) and polling the DO pin; DO low indicates that the write operation is not completed, while DO high indicates that the device is ready for the next instruction. If necessary, the DO pin may be placed back into a high impedance state during chip select by shifting a dummy “1” into the DI pin. The DO pin will enter the high impedance state on the falling edge of the clock (SK). Placing the DO pin into the high impedance state is recommended in applica- tions where the DI pin and the DO pin are to be tied together to form a common DI/O pin. Figure 1.
