Notes:
(1) Test Conditions according to “AC Test Conditions” table.
(2) Power-up, Input Reference Voltage VCC = VTH, Reset Output Reference Voltage and Load according to “AC Test Conditions” Table
(3) Power-Down, Input Reference Voltage VCC = VTH, Reset Output Reference Voltage and Load according to “AC Test Conditions” Table
(4) VCC Glitch Reference Voltage = VTHmin; Based on characterization data
5) 0 < VSENSE - VCC, VLOW Output Reference Voltage and Load according to “AC Test Conditions” Table.
(6) This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested.
(7) tPUR and tPUW are the delays required from the time VCC is stable until the specified memory operation can be initiated.
(8) Latch-up protection is provided for stresses up to 100mA on input and output pins from -1 V to VCC + 1 V.
