Both crossing 70% of VDD 600 ns tDH Output Data Hold Time From SCL falling edge crossing 30% of VDD, until SDA enters the 30% to 70% of VDD window 0ns tR SDA and SCL Rise Time From 30% to 70% of VDD 20+ 0.1*Cb 250 ns tF SDA and SCL Fall Time From 70% to 30% of VDD 20+ 0.1*Cb 250 ns Cb Capacitive Loading of SDA or SCL Total on-chip and off-chip 10 400 pF Rpu SDA and SCL Bus Pull-Up Resistor Off-Chip Maximum is determined by tR and tF For Cb = 400pF, max is about 2~2.5k Ω For Cb = 40pF, max is about 15~20k Ω 1k Ω tSU:WP WP Setup Time Before START condition 600 ns tHD:WP WP Hold Time After STOP condition 600 ns NOTES: 2. Typical values are for TA = 25°C and VDD = 3.3V. 3. LSB = (V(RW)127 – V(RW)0)/127. V(RW)127 and V(RW)0 are the voltage at pin RW for the DCP Register set to 7F hex and 00 hex respectively. 4. FSerror = (V(RW)127 – VDD)/LSB 5. ZSerror = V(RW)0/LSB 6. DNL = [(V(RW) i – V(RW) i-1)/LSB] – 1, for i from 1 to 127. i is the DCP Register setting. 7. INL = [V(RW) i – i * LSB – V(RW)0]/LSB, for I = 1 to 127. 8. for i = 16 to 111, and T = -40°C to 85°C 9. MI = (R0 – R127)/127. MI is minimum increment. R0 and R127 are the resistances between RH and RW with the DCP Register set to 00 hex and 7F hex, respectively. 10. RDNL = (R i – R i-1)/MI – 1, for i from 1 to 111. i is the DCP Register setting. 11. RINL = [R i – (MI * i) – R127]/MI, for i from 1 to 111. 12. ; for i = 1 to 111, and T = -40°C to 85°C 13. tWC is the minimum cycle time to be allowed for any non-volatile Write by the user, unless Acknowledge Polling is used. It is the time from a valid STOP condition at the end of a Write sequence of a I2C serial interface Write operation, to the end of the self-timed internal non-volatile write cycle. 14. Parameter is not 100% tested. Electrical Specifications Over recommended operating conditions unless otherwise stated. All voltages with respect to GND.
