AS4C64M8D2-25BAN Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the AS4C64M8D2-25BAN is 0°C to 70°C (commercial grade) and -40°C to 85°C (industrial grade).
  • The AS4C64M8D2-25BAN requires a refresh cycle every 64ms (tREF) to maintain data integrity. You can use a refresh counter to keep track of the refresh cycles and issue an AUTO REFRESH command (CBR) to refresh the entire memory array.
  • The AS4C64M8D2-25BAN supports a maximum clock frequency of 166MHz.
  • During power-up, apply power to VDD and VDDQ simultaneously, and then wait for a minimum of 200us before applying a clock signal. During power-down, remove the clock signal and then power down VDD and VDDQ simultaneously.
  • The AS4C64M8D2-25BAN has a latency of 2 clock cycles (CL2) for read and write operations.
