... The Microchip Technology Inc. 93XX46A/B/C devices are 1K bit low voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93AA46C, 93LC46C or 93C46C are dependent upon external logic levels driving the 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 ...

... For added protection, an EWDS command should be performed after every write operation. After power-up, the device is automatically in the EWDS mode. Therefore, an EWEN instruction must be performed before the initial ERASE or WRITE instruction can be executed. Block Diagram V CC Memory Array Data Register DI Mode Decode ORG* Logic CS Clock ...

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 ...

... 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 ‘ ...

For proper operation, ORG must be tied to a valid logic level. 93XX46A devices are always x8 organization and 93XX46B devices are always x16 organization ...
