93AA66CT-I/ST Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the 93AA66CT-I/ST is 2.5V to 5.5V, with a typical operating voltage of 3.3V.
  • To ensure data integrity, use a voltage supervisor or a power-on reset (POR) circuit to guarantee a clean power-up sequence. Additionally, use a capacitor to filter out noise and voltage spikes.
  • The 93AA66CT-I/ST supports a maximum clock frequency of 1 MHz, but it's recommended to operate at a frequency of 400 kHz or lower to ensure reliable operation.
  • The 93AA66CT-I/ST is rated for operation up to 125°C, but it's essential to follow proper thermal management and design guidelines to ensure reliable operation in high-temperature environments.
  • The HOLD pin should be tied to VCC or left floating during normal operation. It's only used to pause the device during a bus conflict or when the device is not being accessed.
