The maximum operating temperature range for CY7C251-65DMB is -40°C to +85°C.
The CY7C251-65DMB requires a clock signal with a frequency range of 10-66 MHz. You can use an external clock source or generate a clock signal using a crystal oscillator or a phase-locked loop (PLL).
The maximum data transfer rate for the CY7C251-65DMB is 66 MHz, which translates to a data transfer rate of 528 Mbps.
The CY7C251-65DMB can operate in either synchronous or asynchronous mode. To configure the device for synchronous operation, connect the clock signal to the CLK pin and use the SYNCE pin to synchronize the data transfer. For asynchronous operation, connect the clock signal to the CLK pin and use the ASYNC pin to control the data transfer.
The power consumption of the CY7C251-65DMB depends on the operating frequency and voltage. At a frequency of 66 MHz and a voltage of 3.3V, the typical power consumption is around 150 mW.
