CY62147EV30LL-45BVIT datasheet by Cypress Semiconductor

CY62147EV30LL-45BVIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62147EV30LL-45BVIT 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-45BVIT requires a stable VCC supply before applying clock and input signals. 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-45BVIT supports clock frequencies up to 45 MHz.
• How do I ensure data retention during power-down?
  The CY62147EV30LL-45BVIT has a built-in data retention feature that allows it to retain data for a short period (typically 10 ms) during power-down. However, it is recommended to use an external battery backup or capacitor to ensure data retention for longer periods.
• What is the typical standby current consumption of this SRAM?
  The CY62147EV30LL-45BVIT has a typical standby current consumption of 2 mA at 45 MHz and 1.8V VCC.
