8 / 18 page 8 FN6423.1 March 13, 2008 Cb (Note 19) Capacitive Loading of SDA or SCL Total on-chip and off-chip 10 400 pF Rpu (Note 19) 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:A A1 and A0 Setup Time Before START condition 600 ns tHD:A A1 and A0 Hold Time After STOP condition 600 ns NOTES: 5. Typical values are for TA = +25°C and 3.3V supply voltage. 6. LSB: [V(RW)255 – V(RW)0]/255. V(RW)255 and V(RW)0 are V(RW) for the DCP register set to FF hex and 00 hex respectively. LSB is the incremental voltage when changing from one tap to an adjacent tap. 7. ZS error = V(RW)0/LSB. 8. FS error = [V(RW)255 – VCC]/LSB. 9. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 255. i is the DCP register setting. 10. INL = [V(RW)i – i • LSB – V(RW)0]/LSB for i = 1 to 255. 11. VMATCH= [V(RWx)i -V(RWy)i]/LSB, for i = 0 to 255, x = 0 to 3, y = 0 to 3. 12. for i = 16 to 240 decimal, T = -40°C to +125°C. Max( ) is the maximum value of the wiper voltage and Min ( ) is the minimum value of the wiper voltage over the temperature range. 13. MI = |RW255 – RW0|/255. MI is a minimum increment. RW255 and RW0 are the measured resistances for the DCP register set to FF hex and 00 hex respectively. 14. Roffset = RW0/MI, when measuring between RW and RL. Roffset = RW255/MI, when measuring between RW and RH. 15. RDNL = (RWi – RWi-1)/MI -1, for i = 16 to 255. 16. RINL = [RWi – (MI • i) – RW0]/MI, for i = 16 to 255. 17. RMATCH= [(Rx)i -(Ry)i]/MI, for i = 0 to 255, x = 0 to 3, y = 0 to 3. 18. for i = 16 to 240, T = -40°C to +125°C. Max( ) is the maximum value of the resistance and Min ( ) is the minimum value of the resistance over the temperature range. 19. This parameter is not 100% tested. 20. tWC is the time from a valid STOP condition at the end of a Write sequence of I 2C serial interface, to the end of the self-timed internal non- volatile write cycle. 21. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested. Operating Specifications Over the recommended operating conditions unless otherwise specified.
