CY7C4291V-15JXC datasheet by Cypress Semiconductor

CY7C4291V-15JXC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY7C4291V-15JXC?
  The maximum operating temperature range for CY7C4291V-15JXC is -40°C to +85°C.
• How do I implement a reset circuit for CY7C4291V-15JXC?
  A simple reset circuit can be implemented using a 10kΩ resistor, a 10μF capacitor, and a diode. The resistor and capacitor form an RC network that generates a reset pulse when power is applied, and the diode ensures that the reset signal is not affected by noise.
• What is the recommended clock frequency for CY7C4291V-15JXC?
  The recommended clock frequency for CY7C4291V-15JXC is 15 MHz, but it can operate up to 33 MHz.
• How do I configure the CY7C4291V-15JXC for SPI or I2C interface?
  The CY7C4291V-15JXC can be configured for SPI or I2C interface by setting the MODE pin high or low, respectively. For SPI mode, the MODE pin should be tied high, and for I2C mode, it should be tied low.
• What is the maximum data retention period for CY7C4291V-15JXC?
  The maximum data retention period for CY7C4291V-15JXC is 20 years at 25°C, and 10 years at 85°C.
