Unit ILI Input leakage current (E1, E2, SCL, SDA) VIN = VSS or VCC device in Standby mode ± 2 µA ILO Output leakage current SDA in Hi-Z, external voltage applied on SDA: VSS or VCC ± 2 µA ICC Supply current (Read) VCC = 1.8 V, fc= 400 kHz (rise/fall time < 50 ns) 0.8 mA VCC = 2.5 V, fc= 400 kHz (rise/fall time < 50 ns) 1mA VCC = 5.0 V, fc= 400 kHz (rise/fall time < 50 ns) 2mA 1.8 V < VCC < 5.5 V, fc= 1 MHz (1) (rise/fall time < 50 ns) 1. Only for M24xxx-HR6. 2.5 mA ICC0 Supply current (Write) During tW, 1.8 V < VCC < 5.5 V 5(2) 2. Characterized value, not tested in production. mA ICC1 Standby supply current Device not selected(3), VIN = VSS or VCC, VCC = 1.8 V 3. The device is not selected after power-up, after a READ command (after the Stop condition), or after the completion of the internal write cycle tW (tW is triggered by the correct decoding of a WRITE command). 1µA Device not selected(3), VIN = VSS or VCC, VCC = 2.5 V 2µA Device not selected(3), VIN = VSS or VCC, VCC = 5.5 V 3µA VIL Input low voltage (SCL, SDA, WC) 1.8 V ≤ VCC < 2.5 V –0.45 0.25 VCC V 2.5 V ≤ VCC ≤5.5 V –0.45 0.3 VCC VIH Input high voltage (SCL, SDA, WC) 1.8 V ≤ VCC < 2.5 V 0.75VCC VCC+1 V 2.5 V ≤ VCC ≤ 5.5 V 0.7VCC VCC+1 VOL Output low voltage IOL = 1 mA, VCC = 1.8 V 0.2 V IOL = 2.1 mA, VCC = 2.5 V 0.4 V IOL = 3.0 mA, VCC = 5.5 V 0.4 V |
