Instructions for CAT28C64BP-90:
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 1.6V to 5.5V.
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.
Access Time:
- The access time should be 90ns when operating at VCC = 5V.
Write Cycle Time:
- Allow a minimum of 500μs for each write cycle when VCC is 5V to ensure data integrity.
Data Retention:
- The device guarantees data retention for up to 10 years under specified operating conditions.
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.
Programming:
- Follow the specific programming protocol detailed in the datasheet for successful data writing and reading operations.
