CY62256LL-70PC datasheet by Cypress Semiconductor

CY62256LL-70PC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY62256LL-70PC?
  The maximum operating temperature range for CY62256LL-70PC is -40°C to +85°C.
• How do I handle power-up and power-down sequencing for CY62256LL-70PC?
  It is recommended to power up VCC before VPP, and power down VPP before VCC to prevent latch-up. Additionally, ensure that VCC and VPP are powered up and down slowly (dv/dt < 10V/ms) to prevent voltage overshoots.
• What is the recommended decoupling capacitor value for CY62256LL-70PC?
  A decoupling capacitor of 0.1uF to 1uF is recommended to be placed as close as possible to the VCC pin to filter out noise and reduce power supply ripple.
• How do I ensure data retention in CY62256LL-70PC during power-down?
  To ensure data retention during power-down, ensure that VCC is reduced to 0V before VPP, and that the device is in a standby mode (CE = HIGH) before power-down.
• What is the maximum clock frequency for CY62256LL-70PC?
  The maximum clock frequency for CY62256LL-70PC is 70MHz.
