Instructions for W29C011A-15

1. Power Supply:

   • Ensure that the supply voltage (Vcc) is within the range of 2.7V to 5.5V.
   • The standby current (ISB) should be monitored to ensure it remains within the specified range.

2. Programming:

   • Apply the programming voltage (Vpp) of 12.75V to the chip select pin during programming.
   • The programming current (IPGM) should be between 20mA and 40mA.
   • The programming time (TPGM) should be between 50μs and 150μs.

3. Erase:

   • To erase the device, apply the erase voltage (Vpp) of 12.75V to the chip select pin.
   • The erase time (TERS) should be between 2 seconds and 8 seconds.

4. Temperature:

   • The operating temperature (Topr) should be between -40°C and 85°C.
   • The storage temperature (Tstg) should be between -65°C and 150°C.

5. Output Levels:

   • Ensure that the output high voltage (VOH) is at least 2.4V and no more than Vcc - 0.4V.
   • Ensure that the output low voltage (VOL) is no more than 0.4V.

6. Input/Output Currents:

   • The input leakage current (IIH) should not exceed ±1μA.
