AT24C128B-PU Frequently Asked Questions (FAQs)

  • The AT24C128B-PU has a minimum of 1 million write cycles, but this can vary depending on the usage and environmental conditions.
  • The AT24C128B-PU uses a page write buffer to handle page writes. For block writes, you need to use the page write buffer to write data in chunks of 32 bytes or less. Refer to the datasheet for specific timing and protocol details.
  • The recommended clock frequency for the AT24C128B-PU is up to 1 MHz, but it can operate at frequencies up to 3.4 MHz. However, higher frequencies may require additional power and may affect reliability.
  • The AT24C128B-PU has a built-in power-on reset circuit that resets the device during power-up. During power-down, the device enters a low-power standby mode to conserve power. Refer to the datasheet for specific power-up and power-down timing requirements.
  • The AT24C128B-PU has an operating temperature range of -40°C to +85°C, but it can be extended to -40°C to +125°C for industrial-grade devices.
