The CAT93C86 can be organized as either registers of 16 bits or 8 bits. When organized as X16, seven 13-bit instructions control the reading, writing and erase operations of the device. When organized as X8, seven 14-bit instructions control the reading, writing and erase operations of the device. The CAT93C86 operates on a single power supply and will generate on chip, the high voltage required during any write operation. is in Program Enabled mode. For Write Enable and Write Disable instruction PE = don’t care. 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. After the initial data word has been shifted out and CS remains asserted with the SK clock continuing to toggle, the device will automatically increment to the next address and shift out the next data word in a sequential READ mode. As long as CS is continuously asserted and SK continues to toggle, the device will keep incrementing to the next address automatically until it reaches to the end of the address space, then loops back to address 0. In the sequential READ mode, only the initial data word is preceeded by a dummy zero bit. All subsequent data words will follow without a dummy zero bit. Read Upon receiving a READ command and an address (clocked into the DI pin), the DO pin of the CAT93C86 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 data bits will toggle on the rising edge of the SK clock and are stable after the specified time delay (tPD0 or tPD1). 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 applications where the DI pin and the DO pin are to be tied together to form a common DI/O pin. Write After receiving a WRITE command, address and the data, the CS (Chip Select) pin must be deselected for a minimum of tCSMIN. The falling edge of CS will start the self clocking clear and data store cycle of the memory location specified in the instruction. The clocking of the SK pin is not necessary after the device has entered the self clocking mode. The ready/busy status of the CAT93C86 can be determined by selecting the device and polling the DO pin. Since this device features Auto-Clear before write, it is NOT necessary to erase a memory location before it is written into. The format for all instructions sent to the device is a logical “1” start bit, a 2-bit (or 4-bit) opcode, 10-bit address (an additional bit when organized X8) and for write operations a 16-bit data field (8-bit for X8 organizations). Note: The Write, Erase, Write all and Erase all instructions require PE=1. If PE is left floating, 93C86 Doc. No. MD-1091 Rev. R 4 © 2008 SCILLC.

C) Erase Upon receiving an ERASE command and address, the CS (Chip Select) pin must be deasserted for a minimum of tCSMIN. The falling edge of CS will start the self clocking clear cycle of the selected memory location. The clocking of the SK pin is not necessary after the device has entered the self clocking mode. The ready/busy status of the CAT93C86 can be determined by selecting the device and polling the DO pin. Once cleared, the content of a cleared location returns to a logical “1” state. Erase All Upon receiving an ERAL command, the CS (Chip Select) pin must be deselected for a minimum of tCSMIN. The falling edge of CS will start the self clocking clear cycle of all memory locations in the device. The clocking of the SK pin is not necessary after the device has entered the self clocking mode. The ready/busy status of the CAT93C86 can be determined by selecting the device and polling the DO pin. Once cleared, the contents of all memory bits return to a logical “1” state. Erase/Write Enable and Disable The CAT93C86 powers up in the write disable state. Any writing after power-up or after an EWDS (write disable) instruction must first be preceded by the EWEN (write enable) instruction. Once the write instruction is enabled, it will remain enabled until power to the device is removed, or the EWDS instruction is sent. The EWDS instruction can be used to disable all CAT93C86 write and clear instructions, and will prevent any accidental writing or clearing of the device. Data can be read normally from the device regardless of the write enable/disable status. Write All Upon receiving a WRAL command and data, the CS (Chip Select) pin must be deselected for a minimum of tCSMIN. The falling edge of CS will start the self clocking data write to all memory locations in the device. The clocking of the SK pin is not necessary after the device has entered the self clocking mode. The ready/busy status of the CAT93C86 can be determined by selecting the device and polling the DO pin. It is not necessary for all memory locations to be cleared before the WRAL command is executed.
