93AA66/P Frequently Asked Questions (FAQ)

  • The maximum clock frequency for the 93AA66/P is 1 MHz, as specified in the datasheet. However, it's recommended to operate the device at a frequency of 400 kHz or less to ensure reliable operation and minimize power consumption.

  • During power-up, the HOLD pin should be pulled high to ensure that the device is in a known state. During power-down, the HOLD pin should be pulled low to prevent any unwanted writes to the device. It's also recommended to add a pull-up resistor to the HOLD pin to ensure it's in a known state during power-up.

  • The recommended voltage range for the 93AA66/P is 4.5V to 5.5V. Operating the device outside of this range may affect its reliability and performance.

  • To ensure data integrity during power failures, it's recommended to use a capacitor or a battery-backed system to maintain power to the device during power failures. Additionally, the device has a built-in power-on reset (POR) circuit that helps to prevent data corruption during power-up.

  • The 93AA66/P has a minimum of 100,000 write cycles, as specified in the datasheet. However, the actual number of write cycles may vary depending on the operating conditions and usage patterns.
