(VCC = 1.7 V to 5.5 V, TA = −40°C to +85°C and VCC = 2.5 V to 5.5 V, TA = −40°C to +125°C, unless otherwise specified.) (Note 6)
VCC = 1.7 V − 5.5 V
VCC = 2.5 V − 5.5 V

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.

6. AC Test Conditions:
Input Pulse Voltages: 0.3 VCC to 0.7 VCC
Input rise and fall times: ≤ 10 ns
Input and output reference voltages: 0.5 VCC
Output load: current source IOL max/IOH max; CL = 30 pF
7. This parameter is tested initially and after a design or process change that affects the parameter.
8. tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated.
9. tWC is the time from the rising edge of CS after a valid write sequence to the end of the internal write cycle.
10. The tWC time can be set by the user to allow faster internal writes (max 3 ms) by setting the tWC bit from the Status Register. The fast write
mode is recommended for VCC > 2.5 V.
