Instructions for Use:
Power Supply:
- Ensure that the supply voltage (VCC) is within the range of 4.5V to 5.5V.
- The device requires a secondary supply voltage (VPP) of 12.0V for programming and erase operations.
Current Considerations:
- The quiescent current (ISB) should not exceed 20μA when the device is in standby mode.
- The active current (ICC) should be monitored to ensure it does not exceed 15mA during continuous read cycles.
Timing Parameters:
- The access time (tAC) is 20ns, which is the time from the valid address to the valid data output.
- Ensure that all timing parameters are met to avoid data corruption or incorrect operation.
Signal Levels:
- The output high level (VOH) should be at least 2.4V when the output is driving a load of -0.4mA.
- The output low level (VOL) should be no more than 0.4V when the output is driving a load of 0.4mA.
- Input signals should be within the specified input high level (VIH) and input low level (VIL) ranges.
Environmental Conditions:
- The device is designed to operate within a temperature range of 0°C to 70°C.
- Store the device in a temperature range of -65°C to 150°C to ensure long-term reliability.
Data Retention:
- The device can retain data for up to 10 years at a temperature of 85°C.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal circuitry.
- Follow proper ESD (Electrostatic Discharge) precautions when handling the device.
Mounting:
- Ensure that the device is mounted on a PCB with appropriate thermal management to maintain operating temperatures within the specified range.
Testing:
- Perform functional tests to verify the correct operation of the device after installation.
- Use the specified test conditions to ensure accurate results.
