CHARACTERISTICS Note: (1) This parameter is tested initially and after a design or process change that affects the parameter. (2) 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 (3) tWC is the time from the rising edge of CS after a valid write sequence to the end of the internal write cycle. (4) This parameter is tested initially and after a design or process change that affects the parameter. (5) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated. Power-Up Timing(4)(5) Symbol Parameter Max. Units tPUR Power-up to Read Operation 1 ms tPUW Power-up to Write Operation 1 ms CL = 50pF (2) Test |
