FUNCTIONAL DESCRIPTION Instructions, addresses, and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is normally held in a HIGH-Z state except when reading data from the device, ...

... Erase All (ERAL) The Erase All (ERAL) instruction will erase the entire memory array to the logical “1” state. The ERAL cycle is identical to the ERASE cycle except for the different opcode. The ERAL cycle is completely self-timed and commences at the falling edge of the CS. Clocking of the CLK pin is not necessary after the device has entered the ERAL cycle ...

... The READ instruction outputs the serial data of the addressed memory location on the DO pin. A dummy zero bit precedes the 8-bit (93LC66A) or 16-bit (93LC66B) output string. The output data bits will tog- gle on the rising edge of the CLK and are stable after the specified time delay (T sible when CS is held high ...

... WRITE The WRITE instruction is followed by 8 bits (93LC66A bits (93LC66B) of data which are written into the specified address. After the last data bit is put on the DI pin, the falling edge of CS initiates the self-timed auto- erase and programming cycle. The DO pin indicates the READY/BUSY status of the ...
