M25P80-VMW6T Frequently Asked Questions (FAQs)

• What is the maximum number of erase cycles for the M25P80-VMW6T?
  The M25P80-VMW6T has a minimum of 100,000 erase cycles per sector, and a total of 20,000,000 erase cycles for the entire device.
• How do I handle the HOLD pin during power-up and power-down?
  The HOLD pin should be kept high during power-up and power-down to prevent any unwanted commands from being executed. It's recommended to connect the HOLD pin to VCC through a resistor to ensure it remains high during these transitions.
• What is the recommended clock frequency for the SPI interface?
  The M25P80-VMW6T supports clock frequencies up to 104 MHz, but it's recommended to use a clock frequency of 50 MHz or lower to ensure reliable operation and minimize power consumption.
• How do I handle the WP pin during normal operation?
  The WP pin should be connected to VCC or left floating during normal operation to allow write operations. Connecting the WP pin to GND will enable the write protection feature, which prevents any write operations to the status register and the memory array.
• What is the purpose of the Deep Power-Down mode?
  The Deep Power-Down mode is a low-power state that reduces the current consumption of the device to a minimum. It's useful for applications that require low power consumption during idle periods, such as battery-powered devices.
