CY7C1021BN-12ZXC datasheet by Cypress Semiconductor

CY7C1021BN-12ZXC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1021BN-12ZXC has an industrial temperature range of -40°C to +85°C, making it suitable for a wide range of applications.
• How do I implement a self-refresh mode to reduce power consumption?
  To implement self-refresh mode, set the SREF bit in the Mode Register (MR) to '1'. This will allow the device to automatically refresh the memory array, reducing power consumption when the device is not being accessed.
• What is the maximum clock frequency supported by this device?
  The CY7C1021BN-12ZXC supports clock frequencies up to 133 MHz, making it suitable for high-speed applications.
• How do I handle interrupts generated by the device?
  The CY7C1021BN-12ZXC has an interrupt output pin (INT) that can be connected to a microcontroller or other interrupt-capable device. When an interrupt occurs, the device asserts the INT pin low. The interrupt can be cleared by reading the Interrupt Status Register (ISR).
• What is the latency for read and write operations?
  The CY7C1021BN-12ZXC has a read latency of 2 clock cycles and a write latency of 1 clock cycle, making it suitable for applications that require fast data access.
