... ORG pin to set word size. For dedicated 8-bit communication, the 93AA46A, 93LC46A or 93C46A devices are available, while the 93AA46B, 93LC46B and 93C46B devices provide dedicated 16-bit communication. Advanced CMOS technology makes these devices ideal for low power, nonvolatile memory applications ...

... FUNCTIONAL DESCRIPTION When the ORG pin (93XX46C) is connected to V the (x16) organization is selected. When it is connected to ground, the (x8) organization is selected. Instruc- tions, addresses and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is ...

... Erase The ERASE instruction forces all data bits of the specified 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 programming 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 93XX46A/B/C powers up in the Erase/Write Disable (EWDS) state. All Programming modes must be preceded by an Erase/Write Enable (EWEN) instruction. Once the EWEN instruction is executed, programming remains enabled until an EWDS instruction is executed or Vcc is removed from the device. ...

... 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 93AA46A/B/C and 93LC46A/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 93AA46A/B/C and 93LC46A/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 ...
