Instructions for 93LC66/SN

1. Power Supply:

   • Ensure the operating voltage (VCC) is within the range of 2.5V to 5.5V.
   • The device operates optimally at 5V.

2. Current Consumption:

   • In standby mode, the current consumption (ICCS) should not exceed 20μA at 2.5V.
   • In active mode, the current consumption (ICCA) should not exceed 2mA at 5V.

3. Write Operation:

   • The write time (tW) is between 2ms and 10ms. Ensure that the write operation is completed before initiating another write or read cycle.
   • The device supports up to 100,000 write cycles.

4. Read Operation:

   • The read time (tR) is between 0.1μs and 1μs. Ensure that the read operation is completed before initiating another read or write cycle.

5. Temperature Ranges:

   • The operating temperature (Toper) range is from -40°C to 85°C.
   • The storage temperature (Tstg) range is from -65°C to 150°C.

6. Memory Configuration:

   • The device has a memory size of 256 bytes organized as 32 x 8 bits.

7. Data Retention:

   • Data retention is guaranteed for at least 10 years under normal operating conditions.

8. Pin Configuration:

   • Refer to the datasheet for the specific pin configuration and connections.

9. Programming:

   • Use standard SPI (Serial Peripheral Interface) commands for communication with the device.
   • Ensure proper timing and sequence of commands to avoid data corruption.

10. Handling:

    • Handle the device with care to avoid static discharge, which can damage the component.
    • Follow recommended soldering and mounting procedures to ensure reliable performance.
