CY62146ELL-45ZSXAT datasheet by Cypress Semiconductor

CY62146ELL-45ZSXAT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62146ELL-45ZSXAT operates from -40°C to +85°C, making it suitable for industrial and commercial applications.
• How do I handle power-up and power-down sequences for this device?
  It's recommended to power up VCC before VSS, and power down VSS before VCC to prevent latch-up. Also, ensure that the input signals are stable before applying VCC.
• What is the maximum clock frequency supported by this SRAM?
  The CY62146ELL-45ZSXAT supports clock frequencies up to 45 MHz, making it suitable for high-speed applications.
• How do I implement a wait state or delay in the read cycle?
  You can implement a wait state by inserting a NOP (No Operation) cycle or by using the CE (Chip Enable) pin to extend the read cycle.
• What is the purpose of the ZZ pin, and how do I use it?
  The ZZ pin is used to put the device in sleep mode, reducing power consumption. To use it, assert the ZZ pin low to enter sleep mode, and de-assert it to return to normal operation.
