CY7C1018CV33-12VXI datasheet by Cypress Semiconductor

CY7C1018CV33-12VXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY7C1018CV33-12VXI can operate from -40°C to +85°C, making it suitable for industrial and commercial applications.
• How do I handle power-up and power-down sequences for this device?
  It's recommended to power up the VCC pin before the VSS pin, and power down the VCC pin after the VSS pin to prevent latch-up. Additionally, ensure that the input signals are stable before applying power.
• What is the recommended termination scheme for the output pins?
  Cypress recommends using a 10-ohm to 20-ohm series resistor on each output pin to prevent overshoot and undershoot, and to reduce electromagnetic interference (EMI).
• Can I use this SRAM in a 3.3V system, even though it's specified for 3.0V to 3.6V?
  Yes, the CY7C1018CV33-12VXI is compatible with 3.3V systems, as it's specified to operate from 3.0V to 3.6V. However, ensure that the input signals and output loads are within the recommended operating conditions.
• How do I handle bus contention and data corruption during power-up and power-down?
  To prevent bus contention and data corruption, use a pull-up or pull-down resistor on the data lines, and ensure that the input signals are stable before applying power. Additionally, consider using a power-on reset (POR) circuit to initialize the device.
