CY7C1021BNV33L-15ZXIT datasheet by Cypress Semiconductor

CY7C1021BNV33L-15ZXIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1021BNV33L-15ZXIT has an industrial temperature range of -40°C to +85°C, making it suitable for use in a wide range of applications.
• How do I implement a self-refresh mode to reduce power consumption?
  To implement self-refresh mode, the device must be in the standby mode (CE# = HIGH, OE# = HIGH, and WE# = HIGH). Then, the SRF input pin must be driven LOW to enable self-refresh. This mode reduces power consumption by automatically refreshing the internal memory array.
• What is the maximum clock frequency supported by this device?
  The CY7C1021BNV33L-15ZXIT supports a maximum clock frequency of 133 MHz, making it suitable for high-speed applications.
• How do I handle data retention during power-down?
  To ensure data retention during power-down, the VCC power supply must be maintained above 1.5V. If the power supply voltage falls below 1.5V, the device will automatically enter a low-power standby mode, and data will be retained for a minimum of 10 years.
• What is the typical current consumption of this device?
  The typical current consumption of the CY7C1021BNV33L-15ZXIT is 120 mA at 100 MHz, and 80 mA at 66 MHz. However, this value may vary depending on the specific application and operating conditions.
