Instructions for Use:
Power Supply:
- Connect Vcc to a stable 5V power supply.
- Connect Vpp to 12.5V to 21V during programming and 5V during normal operation.
- Connect GND to ground.
Addressing:
- Apply the desired address to the address lines (A0-A13).
Data Read:
- Set CS low to enable the chip.
- Set OE low to enable data output.
- The data will appear on the data lines (D0-D7).
Programming:
- Set CS low.
- Set WE low.
- Apply the desired address to the address lines.
- Apply the desired data to the data lines.
- Apply 12.5V to 21V to Vpp.
- Hold the signals for the typical programming time (10ms).
- Return Vpp to 5V and release WE and CS.
Erase:
- Expose the chip to UV light for the typical erase time (10 seconds) to erase all memory contents.
Operating Temperature:
- Ensure the operating temperature is within the industrial range (-40°C to +85°C).
Handling:
- Handle the chip with care to avoid static damage.
- Store in a dry environment to prevent moisture damage.
Testing:
- After programming, verify the data by reading it back from the chip to ensure correct programming.
Storage:
- Store the chip in a UV-blocking container to prevent accidental erasure.
