AT93C56B-XHM-T Frequently Asked Questions (FAQs)

  • The AT93C56B-XHM-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 AT93C56B-XHM-T has a built-in POR circuit that ensures the device is in a known state after power-up. The device is ready to operate after the power supply has reached the minimum operating voltage (VCC) and the clock signal is stable.
  • The recommended clock frequency for the AT93C56B-XHM-T is up to 1 MHz, but it can operate at frequencies up to 3 MHz with some limitations.
  • To implement a reliable write operation, ensure that the write cycle is completed within the specified time (tWC), and the device is not accessed during the write cycle. Also, use the correct write protocol and ensure that the device is properly powered.
  • The WP pin is used to enable or disable the write protection feature. When the WP pin is tied to VCC, the device is in write-protect mode, and when it is tied to GND, the device is in normal operation mode.
