24AA16-E/P - Microchip

24AA16-E/P Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the 24AA16-E/P?
  The maximum clock frequency for the 24AA16-E/P is 400 kHz for the 100 kHz and 400 kHz devices, and 1 MHz for the 1 MHz devices.
• How do I handle page writes and block writes in the 24AA16-E/P?
  Page writes are limited to 16 bytes, and block writes are limited to 128 bytes. The device will automatically wrap around to the beginning of the page or block if the write exceeds the page or block boundary.
• What is the purpose of the WP pin on the 24AA16-E/P?
  The WP (Write Protect) pin is used to prevent writes to the entire device or to specific blocks of memory. When WP is tied to VCC, the entire device is write-protected. When WP is tied to GND, the device can be written to, but specific blocks can be write-protected using the block protection bits.
• How do I implement a retry mechanism for writes to the 24AA16-E/P?
  The 24AA16-E/P has a built-in retry mechanism for writes. If a write is interrupted by a reset or power loss, the device will automatically retry the write operation when power is restored. However, it is recommended to implement a retry mechanism in the system software to handle cases where the write operation fails due to other reasons.
• What is the endurance of the 24AA16-E/P?
  The 24AA16-E/P has an endurance of 1 million erase/write cycles per byte, and a data retention of 40 years at 85°C.
