CY62147EV30LL-45BVXA datasheet by Cypress Semiconductor

CY62147EV30LL-45BVXA Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62147EV30LL-45BVXA can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 125°C (extended temperature range) with reduced performance.
• How do I handle power-up and power-down sequences for this SRAM?
  The CY62147EV30LL-45BVXA requires a stable VCC supply before applying clock and input signals during power-up. During power-down, the device should be in a standby mode (CE = HIGH) before removing the VCC supply.
• What is the maximum clock frequency supported by this SRAM?
  The CY62147EV30LL-45BVXA supports clock frequencies up to 45 MHz.
• How do I ensure data retention during power-down?
  To ensure data retention during power-down, the device should be in a standby mode (CE = HIGH) and the VCC supply should be removed slowly (within 10 μs) to prevent data corruption.
• What is the typical standby current consumption of this SRAM?
  The typical standby current consumption of the CY62147EV30LL-45BVXA is around 2 mA at 45 MHz clock frequency.
