Instructions for Using the 24LC08 EEPROM

1. Power Supply:

   • Ensure the operating voltage (VCC) is within the specified range of 1.8V to 5.5V.

2. Addressing:

   • The device has a 7-bit address with three hardware-selectable pins (A0, A1, A2). These pins can be tied to VCC or GND to set the address.

3. Data Transfer Protocol:

   • Communication is via the I2C protocol.
   • Start condition followed by the device address and R/W bit.
   • For write operations, send data bytes after the address byte.
   • For read operations, send the address byte followed by repeated start and then read the data bytes.

4. Write Operations:

   • Before writing, ensure the previous write cycle has completed (wait for at least 5ms).
   • Perform page writes up to 8 bytes at once.

5. Read Operations:

   • Initiate read cycles after setting the memory address.
   • Use repeated start conditions for continuous reading.

6. Handling:

   • Avoid exceeding the maximum ratings to prevent damage.
   • Ensure proper decoupling capacitors are used near the power supply pins to stabilize the power supply.

7. Storage:

   • Store in a dry, cool place when not in use.
   • Data retention is guaranteed for up to 100 years under typical storage conditions.
