AS4C32M8SA-7TCN Frequently Asked Questions (FAQs)

  • The AS4C32M8SA-7TCN has an industrial temperature range of -40°C to 85°C, making it suitable for use in a wide range of applications.
  • The AS4C32M8SA-7TCN requires a refresh cycle every 64ms, and the refresh command should be issued when the device is in the idle state. The refresh cycle consists of an auto-refresh command followed by a self-refresh mode.
  • The AS4C32M8SA-7TCN supports a maximum clock frequency of 166MHz, making it suitable for high-speed applications.
  • During power-up, the VDD and VDDQ pins should be powered up simultaneously, and the clock signal should be stable before applying the chip select signal. During power-down, the clock signal should be stopped, and the chip select signal should be de-asserted before powering down the VDD and VDDQ pins.
  • The AS4C32M8SA-7TCN has a latency of 5 clock cycles (CL5) for read and write operations.
