AS4C8M32SA-7BCN Frequently Asked Questions (FAQs)

  • The AS4C8M32SA-7BCN has an operating temperature range of 0°C to 70°C, and an extended temperature range of -40°C to 85°C for industrial applications.
  • The AS4C8M32SA-7BCN 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 AS4C8M32SA-7BCN supports a maximum clock frequency of 143MHz, with a corresponding data transfer rate of 286Mbps.
  • During power-up, apply power to VDD and VDDQ simultaneously, and then wait for at least 200us before applying a clock signal. During power-down, remove the clock signal and then power down VDD and VDDQ simultaneously.
  • The AS4C8M32SA-7BCN has a latency of 7 clock cycles (CL7) for read and write operations.
