CY62256VNLL-70ZRXI datasheet by Cypress Semiconductor

CY62256VNLL-70ZRXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256VNLL-70ZRXI 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?
  It's recommended to power up the VCC and VCCQ pins simultaneously, and power down the VCCQ pin before the VCC pin. Also, ensure that the input signals are stable before applying power.
• What is the maximum clock frequency supported by this SRAM?
  The CY62256VNLL-70ZRXI supports clock frequencies up to 70 MHz.
• Can I use this SRAM in a 3.3V system?
  Yes, the CY62256VNLL-70ZRXI is compatible with 3.3V systems, but ensure that the VCCQ pin is connected to 3.3V and the input signals are 3.3V-compatible.
• How do I handle bus contention and data corruption during power-up and power-down?
  Use external resistors or buffers to isolate the SRAM from the system bus during power-up and power-down to prevent bus contention and data corruption.
