CAT24C32C4CTR Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the I2C interface is 400 kHz.
  • Page writes are limited to 32 bytes. If more than 32 bytes are sent, the device will ignore the excess data. It's recommended to split large data transfers into smaller chunks.
  • The WP (Write Protect) pin is used to prevent accidental writes to the device. When WP is tied low, the device is write-protected, and any attempt to write to the device will be ignored.
  • To ensure data integrity, it's recommended to use a voltage supervisor or a power-on reset circuit to ensure that the device is not accessed during power-up and power-down.
  • The CAT24C32C4CTR has a minimum of 1 million write cycles, making it suitable for applications that require frequent data updates.
