AT93C46D-TH-T Frequently Asked Questions (FAQs)

  • The AT93C46D-TH-T has a minimum of 100,000 write cycles, but the actual number of write cycles may vary depending on the usage and operating conditions.
  • The AT93C46D-TH-T has a built-in POR and POD circuitry that ensures the device is in a known state after power-up. The POR circuitry holds the device in reset until the power supply has reached a minimum threshold, and the POD circuitry provides a delay after power-up to ensure the device is fully operational before accessing the memory.
  • The recommended operating voltage range for the AT93C46D-TH-T is 2.7V to 5.5V, but the device can operate down to 1.8V with reduced performance and reliability.
  • To implement a reliable write operation, ensure that the device is properly powered, the clock frequency is within the recommended range, and the write cycle is completed within the specified time. Also, use the built-in write protection features, such as the Write Enable Latch (WEL) and the Write Protect (WP) pin, to prevent accidental writes.
  • The Write Protect (WP) pin is used to prevent writes to the memory array. When the WP pin is tied to VCC, the device is in write-protect mode, and any attempt to write to the memory array will be ignored.
