Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (2.7V to 3.6V).
   • Use a stable power source to avoid voltage fluctuations that could affect performance.

2. Standby Mode:

   • To enter standby mode, set the chip select (CS) pin high.
   • The current consumption in standby mode is very low (1-5 μA).

3. Active Mode:

   • Set the chip select (CS) pin low to enter active mode.
   • The active current consumption is typically 10-20 mA.

4. Addressing and Data Access:

   • Provide the correct address to the address lines (A0-A18) before accessing data.
   • The access time is 70 ns, which is the time from when the address is valid to when the data is available on the data lines (D0-D7).

5. Programming:

   • To program a page (256 bytes), ensure the write enable (WE) pin is low and the write protect (WP) pin is high.
   • The typical page write time is 200 μs.

6. Erasing:

   • To erase a sector (64 Kbytes), use the appropriate command sequence and ensure the write enable (WE) pin is low and the write protect (WP) pin is high.
   • The typical sector erase time is 200 ms.
   • To erase the entire chip, use the chip erase command. The typical chip erase time is 4 seconds.

7. Data Retention:

   • The device guarantees data retention for at least 10 years at 85°C.

8. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C.
   • Store the device within the temperature range of -65°C to 150°C.

9. Handling and Storage:

   • Handle the device with care to avoid electrostatic discharge (ESD) damage.
   • Store the device in a dry environment to prevent moisture damage.

10. Package:

    • The device is available in a TSOP-48 package. Ensure proper handling and soldering techniques to avoid damage during assembly.
