24LC32AT/SM Frequently Asked Questions (FAQs)

  • The 24LC32AT/SM has a maximum of 1,000,000 write cycles, with a minimum of 100,000 write cycles guaranteed.
  • The 24LC32AT/SM uses a page write buffer to handle writes. The device can write up to 32 bytes of data in a single page write operation. For block writes, the device can write up to 64 bytes of data in a single block write operation. The device automatically increments the address pointer after each byte is written.
  • The WP (Write Protect) pin is used to prevent writes to the entire memory array or to specific blocks of memory. When the WP pin is tied to VCC, the entire memory array is write-protected. When the WP pin is tied to GND, the memory array is not write-protected. Additionally, the WP pin can be used to write-protect specific blocks of memory by setting the corresponding WPEN bit in the status register.
  • The 24LC32AT/SM requires a specific power-up and power-down sequencing to ensure proper operation. During power-up, the VCC pin should be powered up before the SCL pin. During power-down, the SCL pin should be stopped before the VCC pin is powered down. Additionally, the device should be in a standby mode before power-down to prevent data corruption.
  • The 24LC32AT/SM has a maximum clock frequency of 400 kHz for standard mode and 1 MHz for fast mode.
