CY7C188-20VC datasheet by Cypress Semiconductor

CY7C188-20VC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY7C188-20VC?
  The maximum operating temperature range for CY7C188-20VC 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 CY7C188-20VC?
  The CY7C188-20VC requires a clock signal with a frequency range of 10 MHz to 20 MHz. You can use an external clock source or generate a clock signal using a crystal oscillator or a phase-locked loop (PLL).
• What is the maximum data transfer rate for the CY7C188-20VC?
  The maximum data transfer rate for the CY7C188-20VC is 20 MHz, which translates to a data transfer rate of 40 Mbps.
• How do I handle power-up and power-down sequences for the CY7C188-20VC?
  During power-up, ensure that the clock signal is stable before applying VCC. During power-down, ensure that the clock signal is stopped before removing VCC. Also, follow the recommended power-up and power-down sequences to prevent latch-up or other damage to the device.
• What is the recommended termination scheme for the CY7C188-20VC?
  The recommended termination scheme for the CY7C188-20VC is to use a 10-ohm to 20-ohm series resistor at the output of each signal line, and a 10-ohm to 20-ohm parallel resistor at the input of each signal line.
