... FUNCTIONAL DESCRIPTION When the ORG pin (93XX56C) pin is connected the (x16) organization is selected. When 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 read- ...
Page 7
... Erase The ERASE instruction forces all data bits of the speci- fied address to the logical ‘1’ state brought low following the loading of the last address bit. This falling edge of the CS pin initiates the self-timed program- ming cycle, except on ‘93C’ devices where the rising edge of CLK before the last address bit initiates the write cycle ...
Page 8
... 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, except on ‘ ...

... Erase/Write Disable and Enable (EWDS/EWEN) The 93XX56A/B/C powers up in the Erase/Write Disable (EWDS) state. All programming modes must be preceded by an Erase/Write Enable (EWEN) instruction.

... 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. For 93AA56A/B/C and 93LC56A/B/C devices, after the last data bit is clocked into DI, the falling edge of CS initiates the self-timed auto-erase and programming cycle ...

... Write All (WRAL) The Write All (WRAL) instruction will write the entire memory array with the data specified in the command. For 93AA56A/B/C and 93LC56A/B/C devices, after the last data bit is clocked into DI, the falling edge of CS initiates the self-timed auto-erase and programming cycle ...
