CY62256NLL-55SNXI Frequently Asked Questions (FAQs)

  • The CY62256NLL-55SNXI operates over a temperature range of 0°C to 70°C.
  • The device requires a stable power supply during power-up and power-down sequences. It's recommended to follow a slow power ramp-up and ramp-down sequence to ensure proper operation.
  • A decoupling capacitor of 0.1 μF to 1 μF is recommended to be placed as close to the VCC pin as possible to filter out noise and ensure stable operation.
  • The CY62256NLL-55SNXI is designed to operate at 5V, but it can tolerate a voltage range of 4.5V to 5.5V. However, operating the device outside of its recommended voltage range may affect its performance and reliability.
  • To ensure data retention during power-down, the device must be powered down slowly (typically within 10 ms) to allow the internal voltage regulator to discharge properly. A fast power-down may cause data loss.
