CY7C1021V33-12VC datasheet by Cypress Semiconductor

CY7C1021V33-12VC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY7C1021V33-12VC?
  The maximum operating temperature range for CY7C1021V33-12VC is 0°C to 70°C (commercial grade) and -40°C to 85°C (industrial grade).
• How do I implement a self-refresh mode in CY7C1021V33-12VC?
  To implement self-refresh mode, assert the CE# pin low and then clock in the self-refresh command (CBA10 = 0, CBA9 = 0, CBA8 = 1, CBA7 = 0, CBA6 = 0, CBA5 = 0, CBA4 = 0, CBA3 = 0, CBA2 = 0, CBA1 = 0, CBA0 = 1) on the address pins. The device will then enter self-refresh mode, reducing power consumption.
• What is the maximum clock frequency supported by CY7C1021V33-12VC?
  The maximum clock frequency supported by CY7C1021V33-12VC is 133 MHz.
• How do I handle interrupts in CY7C1021V33-12VC?
  CY7C1021V33-12VC does not have an interrupt output pin. Instead, the device uses a flag bit in the status register to indicate the completion of a write operation or the occurrence of an error. The host processor must poll the status register to detect these events.
• What is the latency for a read operation in CY7C1021V33-12VC?
  The latency for a read operation in CY7C1021V33-12VC is 2 clock cycles.
