93C46AT-E/SN Frequently Asked Questions (FAQ)

  • The 93C46AT-E/SN has a minimum of 100,000 write cycles, but this can vary depending on the operating conditions and usage patterns.

  • The 93C46AT-E/SN uses a page write mode for writing data to the EEPROM. The page size is 16 bytes, and the device can perform block writes of up to 16 bytes. To perform a page write, the device must be in the write enable state, and the correct page address must be sent.

  • The WP (Write Protect) pin is used to prevent writes to the entire device or a specific block of the device. When the WP pin is tied low, the entire device is write-protected. When the WP pin is tied high, the device can be written to, but specific blocks can be write-protected using the block protection bits.

  • To implement a reliable write operation, ensure that the device is in the write enable state, and the correct page address is sent. Also, use a valid clock frequency, and ensure that the write cycle is completed within the specified time. Additionally, use a robust write verification mechanism to ensure that the data is written correctly.

  • The recommended clock frequency for the 93C46AT-E/SN is up to 1 MHz, but it can operate at frequencies up to 3 MHz with some limitations. It's essential to consult the datasheet for specific clock frequency requirements and limitations.
