Instructions for Use:
Power Supply:
- Connect Vcc to a stable power supply within the range of 1.8V to 3.6V.
- Ensure GND is connected to the system ground.
Addressing:
- Use the address lines (A0-A14) to select the memory location you want to read from or write to.
Data Transfer:
- Data lines (D0-D7) are used for data input and output.
- To read data, set /OE low while /CS is low.
- To write data, set /WE low while /CS is low.
Chip Select:
- /CS must be low to enable the device for read or write operations.
- When /CS is high, the device is in standby mode, consuming minimal current.
Write Protect:
- The /WP pin can be used to prevent unintentional writes. Set /WP high to enable write protection.
Timing:
- Ensure that all timing parameters, such as access time, are met to avoid data corruption.
Endurance and Data Retention:
- The device supports up to 10^14 write cycles and retains data for at least 10 years at 85°C.
Temperature Considerations:
- Operate the device within the specified temperature range (-40°C to +85°C) for reliable performance.
- Store the device within the storage temperature range (-55°C to +125°C).
Handling:
- Handle the device with care to avoid static damage. Use proper ESD precautions.
Mounting:
- Ensure proper soldering and mounting techniques to avoid mechanical stress on the package.
