Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range of 3.3V ± 0.3V.
   • Use a stable power supply to avoid data corruption.

2. Temperature Range:

   • Operate the device within the temperature range of -40°C to +85°C to ensure reliable performance.

3. Access Time:

   • The typical access time is 45 ns. Design your system to accommodate this timing to prevent data loss or corruption.

4. Data Retention:

   • The device retains data for up to 10 years at 25°C. For longer retention, maintain the device at lower temperatures.

5. Package Handling:

   • Handle the 44-pin TSOP II package with care to avoid damage to the pins.
   • Ensure proper soldering techniques to avoid thermal shock and mechanical stress.

6. Data Input/Output:

   • The device supports 16-bit I/O operations. Ensure that the input signals are TTL/CMOS compatible.
   • The maximum output drive current is 12 mA.

7. Write Cycle:

   • The minimum write cycle time is 45 ns. Ensure that the write operations are synchronized with this timing.

8. Power Consumption:

   • The typical power consumption in active mode is 100 mW. In standby mode, the current draw is limited to 1 μA.

9. Clock Frequency:

   • The maximum clock frequency is 22 MHz. Ensure that the system clock is within this limit to avoid timing issues.

10. Storage:

    • Store the device in a dry, cool environment to prevent moisture damage and ensure long-term reliability.
