CY7C149-25PC datasheet by Cypress Semiconductor

CY7C149-25PC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY7C149-25PC?
  The maximum operating temperature range for CY7C149-25PC is 0°C to 70°C (commercial grade) and -40°C to 85°C (industrial grade).
• How do I implement a clock signal for the CY7C149-25PC?
  The CY7C149-25PC requires a clock signal to operate. You can implement a clock signal using an external clock source, such as a crystal oscillator or a clock generator IC. The clock signal should be connected to the CLK pin (Pin 14) and should meet the specified clock frequency and duty cycle requirements.
• What is the maximum clock frequency supported by CY7C149-25PC?
  The maximum clock frequency supported by CY7C149-25PC is 25 MHz.
• How do I configure the CY7C149-25PC for asynchronous or synchronous operation?
  The CY7C149-25PC can be configured for asynchronous or synchronous operation by setting the MODE pin (Pin 13) high or low. For asynchronous operation, the MODE pin should be tied high, and for synchronous operation, the MODE pin should be tied low.
• What is the purpose of the CE (Chip Enable) pin on the CY7C149-25PC?
  The CE (Chip Enable) pin (Pin 12) is used to enable or disable the device. When the CE pin is low, the device is enabled, and when it is high, the device is disabled. This pin can be used to power down the device when not in use to reduce power consumption.
