W25Q256JWEIM Frequently Asked Questions (FAQs)

  • The W25Q256JWEIM has a minimum of 100,000 erase cycles per sector, and a total of 20,000,000 erase cycles for the entire device.
  • The HOLD# pin should be pulled high during power-up and power-down to prevent any unwanted commands from being executed. It's recommended to connect a pull-up resistor to VCC.
  • The W25Q256JWEIM supports clock frequencies up to 104 MHz. However, it's recommended to use a clock frequency of 50 MHz or lower for reliable operation.
  • The WP# pin should be connected to VCC to enable write protection. When WP# is low, the device is in write-enable mode. When WP# is high, the device is in write-protect mode.
  • The W25Q256JWEIM has a typical read latency of 30ns, and a typical program latency of 3ms. The erase latency varies depending on the sector size, but is typically around 300ms.
