AT28BV64B-20JU-T Frequently Asked Questions (FAQs)

  • The AT28BV64B-20JU-T has an operating temperature range of -40°C to +85°C.
  • The device has a power-up and power-down sequence that must be followed to ensure proper operation. The VCC pin should be powered up before the CE pin, and the CE pin should be powered down before the VCC pin.
  • The recommended voltage range for the VCC pin is 2.7V to 3.6V.
  • To implement a reliable write operation, ensure that the WE pin is low, the CE pin is low, and the OE pin is high. Also, ensure that the address and data lines are stable before and during the write operation.
  • The WP pin is a write-protect pin that allows the user to protect the entire memory array from write operations. To use it, tie the WP pin to VCC to enable write protection, or tie it to GND to disable write protection.
