Instructions for CAT28C64BP-90:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 1.6V to 5.5V.

2. Output Current Handling:

   • When VCC is set to 5V and output voltage (VO) is at 2.7V, ensure the output current does not exceed -4mA or fall below -8mA.
   • For low output conditions (VO = 0.4V), maintain the output current between 4mA and 8mA.

3. Access Time:

   • The access time should be 90ns when operating at VCC = 5V.

4. Write Cycle Time:

   • Allow a minimum of 500渭s for each write cycle when VCC is 5V to ensure data integrity.

5. Data Retention:

   • The device guarantees data retention for up to 10 years under specified operating conditions.

6. Handling Precautions:

   • Avoid exceeding the maximum ratings as this can cause permanent damage to the device.
   • Use appropriate decoupling capacitors near the power supply pins to minimize noise and transient effects.

7. Programming:

   • Follow the specific programming protocol detailed in the datasheet for successful data writing and reading operations.
