4. AC Test Conditions:
Input Pulse Voltages: 0.3 V_CC to 0.7 V_CC
Input rise and fall times: ≤ 10 ns
Input and output reference voltages: 0.5 V_CC
Output load: current source I_{OL max}/I_{OH max}; C_L = 50 pF
5. This parameter is tested initially and after a design or process change that affects the parameter.

6. t_WC is the time from the rising edge of CS after a valid write sequence to the end of the internal write cycle.
7. All Chip Select (CS) timing parameters are defined relative to the positive clock edge (Figure 2). t_CSH timing specification is valid
for die revision C and higher. The die revision C is identified by letter “C” or a dedicated marking code on top of the package. For
previous product revision (Rev. B) the t_CSH is defined relative to the negative clock edge.

8. t_PUR and t_PUW are the delays required from the time V_CC is stable until the specified operation can be initiated.
