Instructions:
Power Supply:
- Ensure the device is powered within the specified voltage range (4.5V to 5.5V).
Programming:
- Apply the programming voltage (12.5V) to the Vpp pin.
- Write data to the desired memory location using the appropriate address and data lines.
- Each byte typically takes 3 milliseconds to program.
Erase:
- Apply the programming voltage (12.5V) to the Vpp pin.
- Perform a chip erase by setting all address lines to high and applying the erase command.
- The typical erase time is 10 seconds.
Reading:
- Apply the operating voltage (4.5V to 5.5V) to Vcc.
- Set the address lines to the desired memory location.
- Read the data from the data lines.
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.
Handling:
- Handle the device with care to avoid static discharge.
- Follow proper ESD (Electrostatic Discharge) precautions during handling and installation.
Storage:
- Store the device in a dry environment to prevent moisture damage.
Endurance:
- The device can withstand up to 1,000 write/erase cycles.
Data Retention:
- Data will be retained for at least 10 years under normal operating conditions.
