Instructions for Use

1. Power Supply:

   • Ensure the supply voltage is within the specified range of 2.5V to 5.5V.
   • Connect VCC to the positive power supply and GND to the ground.

2. Pin Configuration:

   • VCC: Power supply input.
   • GND: Ground.
   • A0-A10: Address lines.
   • D0-D7: Data lines.
   • /CS: Chip select (active low).
   • /WE: Write enable (active low).
   • /OE: Output enable (active low).

3. Read Operation:

   • Set /CS to low to select the chip.
   • Set /OE to low to enable output.
   • Apply the desired address to A0-A10.
   • Data will be available on D0-D7 after the access time.

4. Write Operation:

   • Set /CS to low to select the chip.
   • Set /WE to low to enable writing.
   • Apply the desired address to A0-A10.
   • Apply the data to be written to D0-D7.
   • Hold /WE low for at least the write cycle time (5 ms).
   • Return /WE to high to complete the write operation.

5. Standby Mode:

   • Set /CS to high to put the device into standby mode.
   • In this mode, the device consumes minimal current (1 渭A max).

6. Temperature Considerations:

   • Ensure the operating temperature is within the range of -40掳C to 85掳C to avoid damage or malfunction.

7. Endurance:

   • The device can withstand up to 1,000,000 write/erase cycles.

8. Storage:

   • Store the device in a dry, cool place to prevent moisture damage.
