CHARACTERISTICS CL = 50pF (2) PIN CAPACITANCE (1) Applicable over recommended operating range from TA=25˚C, f=1.0 MHz, VCC=+5.0V (unless otherwise noted). Symbol Test Conditions Max. Units Conditions COUT Output Capacitance (SO) 8 pF VOUT=0V CIN Input Capacitance ( CS, SCK, SI, WP, HOLD)6 pF VIN=0V 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 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. |
