8 / 12 page FM24C256 Rev 3.1 May 2005 Page 8 of 12 Electrical Specifications Absolute Maximum Ratings Symbol Description Ratings VDD Voltage on VDD with respect to VSS -1.0V to +7.0V VIN Voltage on any signal pin with respect to VSS -1.0V to +7.0V and VIN < VDD+1.0V * TSTG Storage Temperature -55 °C to + 125°C TLEAD Lead temperature (Soldering, 10 seconds) 300 ° C VESD Electrostatic Discharge Voltage - Human Body Model (JEDEC Std JESD22-A114-B) - Machine Model (JEDEC Std JESD22-A115-A) 4kV 400V Package Moisture Sensitivity Level MSL-1 * Exception: The “VIN < VDD+1.0V” restriction does not apply to the SCL and SDA inputs. 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 = 4.5V to 5.5V unless otherwise specified) Symbol Parameter Min Typ Max Units Notes VDD Main Power Supply 4.5 5.0 5.5 V IDD VDD Supply Current @ SCL = 100 kHz @ SCL = 400 kHz @ SCL = 1 MHz 200 500 1.2 µA µA mA 1 ISB Standby Current 100 µA 2 ILI Input Leakage Current 10 µA 3 ILO Output Leakage Current 10 µA 3 VIH Input High Voltage 0.7 VDD VDD + 0.5 V 4 VIL Input Low Voltage -0.3 0.3 VDD V 4 VOL Output Low Voltage @ IOL = 3 mA 0.4 V RIN Address Input Resistance (WP, A2-A0) For VIN = VIL (max) For VIN = VIH (min) 20 1 K Ω M Ω 5 VHYS Input Hysteresis 0.05 VDD V 4 Notes 1. SCL toggling between VDD-0.3V and VSS, other inputs VSS or VDD-0.3V 2. SCL = SDA = VDD. All inputs VSS or VDD. Stop command issued. 3. VIN or VOUT = VSS to VDD. Does not apply to WP, A2-A0 pins. 4. This parameter is characterized but not tested. 5. The input pull-down circuit is strong (20K Ω) when the input voltage is below V IL and weak (1MΩ) when the input voltage is above VIH. This resistance is characterized and not tested. |
