... FUNCTIONAL DESCRIPTION When the ORG* pin is connected to V organization is selected. When it is connected to ground, the (x8) organization is selected. 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, or when checking the READY/ BUSY status during a programming operation ...

... ERASE The ERASE instruction forces all data bits of the specified address to the logical ‘1’ state. The rising edge of CLK before the last address bit initiates the write cycle. FIGURE 2-1: ERASE TIMING CS CLK HIGH-Z DO DS21796D-page 6 The DO pin indicates the READY/BUSY status of the ...

... 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. The rising edge of CLK before the last data bit initiates the write cycle ...

... ERASE/WRITE DISABLE And ENABLE (EWDS/EWEN) The 93XX76A/B/C powers up in the ERASE/WRITE Disable (EWDS) state. All programming modes must be preceded by an ERASE/WRITE Enable (EWEN) instruc- tion. Once the EWEN instruction is executed, program- ming remains enabled until an EWDS instruction is executed removed from the device ...

... WRITE The WRITE instruction is followed by 8 bits (If ORG is low or A-version devices bits (If ORG pin is high or B-version devices) of data which are written into the specified address. The self-timed auto-erase and programming cycle is initiated by the rising edge of CLK on the last data bit. ...

... WRITE ALL (WRAL) The Write All (WRAL) instruction will write the entire memory array with the data specified in the command. The self-timed auto-erase and programming cycle is initiated by the rising edge of CLK on the last data bit. Clocking of the CLK pin is not necessary after the device has entered the WRAL cycle ...
