AT24CSW040-STUM-T Frequently Asked Questions (FAQs)

  • The AT24CSW040-STUM-T has a maximum of 1 million write cycles, making it suitable for applications that require frequent data updates.
  • The AT24CSW040-STUM-T uses a page write buffer to handle page writes. The buffer is 32 bytes, and the device can write up to 32 bytes of data in a single page write operation.
  • The WP (Write Protect) pin is used to prevent accidental writes to the device. When the WP pin is tied to VCC, the entire memory array is write-protected. When tied to GND, the device can be written to normally.
  • Yes, the AT24CSW040-STUM-T is designed to operate in a multi-master I2C bus environment. It has a built-in arbitration mechanism that allows it to share the bus with other I2C devices.
  • The AT24CSW040-STUM-T requires a minimum clock frequency of 100 kHz to operate correctly.
