Notes:
(1) AC Test Conditions:
Input Pulse Voltages: 0.3VCC to 0.7VCC
Input rise and fall times:
≤ 10ns
Input and output reference voltages: 0.5VCC
Output load: current source IOL max/IOH max; CL = 50pF
(2) This parameter is tested initially and after a design or process change that affects the parameter.
(3) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated.
(4) tWC is the time from the rising edge of CS
after a valid write sequence to the end of the internal write cycle.
