CY7C109B-15VI datasheet by Cypress Semiconductor

CY7C109B-15VI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY7C109B-15VI?
  The maximum operating temperature range for CY7C109B-15VI is -40°C to +85°C.
• How do I implement a clock signal for the CY7C109B-15VI?
  The CY7C109B-15VI 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 of the device.
• What is the maximum clock frequency supported by CY7C109B-15VI?
  The maximum clock frequency supported by CY7C109B-15VI is 15 MHz.
• How do I configure the CY7C109B-15VI for asynchronous or synchronous operation?
  The CY7C109B-15VI can operate in either asynchronous or synchronous mode. To configure the device for asynchronous operation, tie the SYNC pin to VCC. To configure the device for synchronous operation, tie the SYNC pin to GND.
• What is the purpose of the VCCQ pin on the CY7C109B-15VI?
  The VCCQ pin is the power supply pin for the output buffers of the CY7C109B-15VI. It should be connected to the same power supply as the VCC pin, but it can be separated from VCC to allow for separate power supply noise filtering or voltage regulation.
