24AA256-E/SN Frequently Asked Questions (FAQ)
-
The 24AA256-E/SN has a minimum of 1 million write cycles, but this can vary depending on the operating conditions and usage patterns.
-
To ensure data integrity, use the WP (Write Protect) pin to prevent accidental writes during power-down or power-up. Additionally, use a voltage supervisor or a power-on reset circuit to ensure that the device is fully powered before accessing the EEPROM.
-
The recommended clock frequency for the 24AA256-E/SN is up to 1 MHz, but it can operate at frequencies up to 3.4 MHz with some limitations. Consult the datasheet for specific timing requirements.
-
The 24AA256-E/SN uses a page-based write architecture. Each page is 64 bytes, and block writes are not supported. To write data, use the page write command and ensure that the data is aligned to the page boundary.
-
The WP pin is used to prevent writes to the EEPROM when it is tied low. This is useful for protecting the EEPROM contents during power-down or power-up, or when the device is in a low-power mode.
