CY62148ESL-55ZAXA datasheet by Cypress Semiconductor

CY62148ESL-55ZAXA Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62148ESL-55ZAXA 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 device?
  The CY62148ESL-55ZAXA requires a stable VCC supply before applying clock and input signals. During power-down, ensure that VCC is reduced to 0V before removing clock and input signals.
• What is the recommended clock frequency for this SRAM?
  The CY62148ESL-55ZAXA can operate at clock frequencies up to 55 MHz. However, the recommended frequency is 45 MHz for optimal performance and power consumption.
• How do I ensure data retention during power-down?
  To ensure data retention, VCC must be reduced to 0V within 10 ns of removing clock and input signals. Additionally, the device must be in a standby mode (CE = HIGH) before power-down.
• What is the typical current consumption of this SRAM?
  The typical current consumption of the CY62148ESL-55ZAXA is 15 mA at 45 MHz clock frequency and 2.7V VCC. However, this value may vary depending on the operating conditions and usage patterns.
