Instructions for FM27C040Q120

1. Power Supply Requirements:

   • Ensure the supply voltage (VCC) is within the range of 2.7V to 5.5V.

2. Current Considerations:

   • The device consumes a standby current of approximately 1渭A at room temperature.
   • During active operations, the current consumption can reach up to 5mA.

3. Data Retention:

   • Data retention is guaranteed for up to 20 years under normal operating conditions.

4. Write Operations:

   • A write cycle takes about 5 milliseconds when the supply voltage is between 4.5V and 5.5V.

5. Erase/Program Durability:

   • Each sector or block can endure up to 100,000 erase/program cycles.

6. Operating Temperature:

   • Ensure the device operates within its specified temperature range to maintain reliability and performance.

For detailed specifications and application notes, refer to the official datasheet provided by the manufacturer.
