6 / 13 page 6 FN6177.0 July 28, 2006 SDA vs SCL Timing A0, A1, and A2 Pin Timing tHD:A A2, 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)127 – V(RW)0]/127. V(RW)127 and V(RW)0 are V(RW) for the DCP register set to 7F 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)127 – VCC]/LSB. 9. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 127. i is the DCP register setting. 10. INL = [V(RW)i – i • LSB – V(RW)0]/LSB for i = 1 to 127. 11. VMATCH = [V(RWx)i – V(RWy)i]/LSB, for i = 1 to 127, x = 0 to 3 and y = 0 to 3. 12. for i = 16 to 112 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 = |RW127 – RW0|/127. RW127 and RW0 are the measured resistances for the DCP register set to 7F hex and 00 hex respectively. 14. Roffset = RW0/MI, when measuring between RW and RL. Roffset = RW127/MI, when measuring between RW and RH. 15. RDNL = (RWi – RWi-1)/MI - 1, for i = 16 to 127. 16. RINL = [RWi – (MI • i) – RW0]/MI, for i = 16 to 127. 17. RMATCH = (RWi,x – RWi,y)/MI, for i = 1 to 127, x = 0 to 3 and y = 0 to 3. 18. for i = 16 to 112, 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.
