6 / 10 page Ramtron FM573/574 27 March 2001 6/10 Electrical Specifications Absolute Maximum Ratings Description Ratings Ambient storage or operating temperature -40 °C to + 85°C Voltage on any pin with respect to ground -1.0V to +7.0V D.C. output current on any pin TBD Lead temperature (Soldering, 10 seconds) 300 ° C Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only, and the functional operation of the device at these or any other conditions above those listed in the operational section of this specification is not implied. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. DC Operating Conditions TA = -40 ° C to + 85° C, VDD = 2.7V to 5.5V unless otherwise specified Symbol Parameter Min Typ Max Units Notes VDD Main Power Supply 2.7 5.5 V 1 VMIN State change blocked/restored 2.40 2.5 2.54 V 1,8 ISB Quiescent Supply Current 125 µA 2 IDDDY Dynamic Supply Current ex. 3.3V, 10 MHz, 8 inputs 20pF*V*f*n 5.28 A mA 3,4,5 IDDNV State Change Supply Current 500 µA 5 ILI Input Leakage Current 10 µA 6 ILO Output Leakage Current 10 µA 6 VIL Input Low Voltage -0.3 0.3*VDD V 1 VIH Input High Voltage 0.7*VDD VDD + 0.5 V 1 VOH Output High Voltage @ IOH = -8 mA VDD>4V @ IOH = -8 mA VDD<4V VDD-0.8 VDD-1.0 V 1,7 VOL Output Low Voltage @ IOL = 8 mA 0.8 V 1,7 Notes 1. Referenced to VSS. 2. C = VSS, all other inputs at VDD or VSS 3. Dynamic supply current depends on the clock frequency, the frequency of inputs toggling, and the number of bits toggling. In the formula, V = VDD; f is clock frequency; n is the number of bits switching. The Dn inputs toggle at approximately a 50% duty-cycle at ½ of the frequency of C and comply with the minimum setup time. Outputs are tri-stated. All input levels at VDD and VSS. If C is static but the inputs toggle (573 in transparent mode), then the f should be the frequency of the inputs. 4. In a realistic system, the IDD needed to drive the loads also should be considered. IL = CL*V*fo *n where CL is the load capacitance, V is the output swing voltage, fo is the output frequency, and n is the number of bits switching. 5. Changes in state cause a nonvolatile write which adds a DC current component to the static power or dynamic for the duration of the nonvolatile write operation. The total current consumption after each state change = ISB + IDDNV + IDDDY. After the state change is recorded, total current consumption = ISB + IDDDY. 6. VIN or VOUT = VSS to VDD 7. This parameter is characterized but not tested. 8. All state changes will be ignored when VDD is below VMIN. VDD rising above VMIN causes the user latch to be restored from the nonvolatile latch. |
