AT93C66B-SSHM-B Frequently Asked Questions (FAQs)

  • The AT93C66B 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 Hold signal (HOLD) is an active-low input that allows the microcontroller to pause the serial communication with the AT93C66B. When the HOLD signal is low, the serial clock (SCK) is ignored, and the device enters a low-power state.
  • The WP (Write Protect) pin is an active-low input that allows the user to write-protect the entire memory array. When the WP pin is low, the device is in a write-protected state, and any attempt to write to the memory will be ignored.
  • The RDY/BUSY pin is an open-drain output that indicates the device status. When the pin is low, the device is busy with an internal operation, and when it is high, the device is ready for the next operation.
  • The recommended operating voltage range for the AT93C66B is 4.5V to 5.5V, but the device can operate down to 3.3V with some limitations on the clock frequency and access time.
