93LC66A/SN Frequently Asked Questions (FAQ)

  • The maximum clock frequency for the 93LC66A/SN is 3.2 MHz.

  • To ensure data integrity, use the internal EEPROM's built-in error correction mechanism, and implement a checksum or CRC in the firmware to detect data corruption.

  • Yes, the 93LC66A/SN is rated for operation up to 125°C, but ensure that the device is properly derated for temperature and voltage to prevent premature wear-out.

  • Implement a power-down detection circuit to detect voltage drops, and use the 93LC66A/SN's built-in power-fail detection feature to prevent data corruption during power-down or brownout conditions.

  • The recommended storage temperature range for the 93LC66A/SN is -65°C to 150°C.
