CY62256L-70PXC datasheet by Cypress Semiconductor

CY62256L-70PXC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY62256L-70PXC?
  The maximum operating temperature range for CY62256L-70PXC is -40°C to +85°C.
• How do I handle power-up and power-down sequencing for CY62256L-70PXC?
  It is recommended to power up VCC before VPP and power down VPP before VCC to prevent latch-up and ensure proper operation.
• What is the recommended PCB layout and routing for CY62256L-70PXC?
  It is recommended to follow Cypress's PCB layout and routing guidelines for SRAM devices, including using a solid ground plane, minimizing signal trace length, and avoiding signal crosstalk.
• Can I use CY62256L-70PXC in a system with multiple voltage supplies?
  Yes, but ensure that the voltage supplies are properly sequenced and that the device is powered up and down correctly to prevent latch-up and damage.
• How do I handle data retention and refresh for CY62256L-70PXC?
  CY62256L-70PXC is a static RAM, so it does not require refresh. However, it is recommended to follow Cypress's guidelines for data retention and power-down modes to ensure data integrity.
