6 / 13 page 6 FN6331.3 May 28, 2009 SDA vs SCL Timing A0, A1, and A2 Pin Timing tSU:A A2, A1 and A0 Setup Time Before START condition 600 ns tHD:A A2, A1 and A0 Hold Time After STOP condition 600 ns NOTES: 3. Typical values are for TA = +25°C and 3.3V supply voltage. 4. 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. 5. ZS error = V(RW)0/LSB. 6. FS error = [V(RW)127 – VCC]/LSB. 7. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 127. i is the DCP register setting. 8. INL = [V(RW)i – i • LSB – V(RW)0]/LSB for i = 1 to 127. 9. VMATCH = [V(RWx)i – V(RWy)i]/LSB, for i = 1 to 127, x = 0 to 3 and y = 0 to 3. 10. for i = 16 to 112 decimal, T = -40°C to +125°C. Max( ) is the maximum value of the wiper minimum value of the resistance over the temperature range. 11. This parameter is not 100% tested. 12. tWC is the time from a valid STOP condition at the end of a Write sequence of I2C serial interface, to the end of the self-timed internal non-volatile write cycle. 13. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested. Operating Specifications Over the recommended operating conditions unless otherwise specified.
