Instructions:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 2.7V to 3.6V.
   • Connect the Vcc pin to the positive power supply and the GND pin to the ground.

2. Pin Configuration:

   • Refer to the datasheet for the specific pinout of the 32-pin PDIP package.
   • Ensure all pins are correctly connected according to the pin configuration.

3. Initialization:

   • After applying power, allow the device to stabilize before initiating any read or write operations.
   • Use the reset pin (if available) to initialize the device.

4. Read Operations:

   • Apply the appropriate address to the address lines.
   • Assert the chip select (CS) and output enable (OE) signals.
   • The data will be available on the data lines after the access time (typically 70ns).

5. Write Operations:

   • Apply the appropriate address to the address lines.
   • Assert the chip select (CS) and write enable (WE) signals.
   • Provide the data to be written on the data lines.
   • Wait for the write cycle time (typically 5ms) to complete before performing another operation.

6. Erase Operations:

   • Apply the appropriate block address to the address lines.
   • Assert the chip select (CS) and block erase (BE) signals.
   • Wait for the block erase time (typically 4 seconds) to complete before performing another operation.

7. Temperature Considerations:

   • Ensure the operating temperature is within the range of -40掳C to +85掳C.
   • Store the device in an environment where the temperature does not exceed -65掳C to +150掳C.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge.
   • Follow proper handling procedures to prevent damage to the pins and internal circuitry.
