(2) Address bit A10 for the 1,024x8 org. and A9 for the 512x16 org. are “don’t care” bits, but must be kept at either a “1” or “0” for READ, WRITE and ERASE commands. (3) The input levels and timing reference points are shown in the “AC Test Conditions” table. (4) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated. |
